LATE CRETACEOUS AND EARLY TERTIARY NON-MARINE GASTROPODS FROM SOUTHERN ANHUI Yii Wen Pan Huazhang Wang Huiji (Nanjing Institute of Geology and Palaeontology, Academia Sinica) Abstract The present paper deals with non-marine gastropod fossils collected by the Red Bed Team of Nanjing Institute of Geology and Palaeontology, Academia Sinica, in 1972—1974 in Late Cretaceous and Early Tertiary red series of Xuancheng, Langxi and Nanling, Southern Anhui. The fossils, well-preserved and quite abundant in number of both species and in- dividuals, described herein are 46 species referred to 28 genera in 13 families, of which 6 genera and 38 species are considered to be new. Except 5 new species of gastropod opercula are erected. CHARACTERS OF FAUNA AND AGE OF THE FOSSILLIFEROUS BEDS The Late Cretaceous deposits occur extensively on the Yangongqiao of Xuancheng and Qilidian of Langxi, namely, Xuannan formation. On the basis of its lithological characters and faunal assemblages, Xuannan formation may be divided into three members: Upper member consists of purplish-red, massive-bedded conglomerate and sandstone with fine-grained conglomerate; Middle member comprises purplish-red or brick-red, finegrained siltstone, fine-grained calcareous siltstone and argillaceous silt- stone intercalated with conglomerate; Lower member is mainly composed of the purplish-red massive-bedded conglomerate and quartz siltstone containing fine-grained conglomerate. The gastopod fossils are imbedded in bricke-red sandy siltstone of upper part of the Middle member. The important elements are Valvata sp., Polycirsus xuanchengensis Pan (sp. nov,), Parhydrohia minima Pan (sp. nov.), Peringia carinata Pan (sp. nov.), Acrostelel incertum Pan ( sp. nov. ), Reesidella orientalis 'P&n (sp. nov.), R. rotundaconvexa Pan (sp. nov.), Truncatella sp., T. rahora Pan (sp. nov.), and Hippeutis langxiensis Pan (sp. nov.). Among them, Valvata sinensis Yii et Lee was first discovered in Upper Cretaceous Sifantai formation of Songliao plain. Therefore, it may be more available for stratigraphic correlation. Truncatella in Xuannan forma- : 26 ^mm^^mMmm^^^m^^mn %\-m tion is rich in variety as well as in individuals, it includes five species. Truncatella magna Yii et Lee has been recorded from Sifangtai formation. Though Truncatella crasiolahia is a new species, it resembles Truncatella maxima Yii et Lee from Upper Cretaceous Sifantai formation. Reesidella rotundaconvexa closely comparable with Rcesidella cathaica Yii et Lee was found from Nenjiang formation of Songliao plain. Besides, Polycirsus and Hippeutis are more closely related to those of Sifangtai forma- tion. It can be clearly seen from the above faunal analysis, that they are more closely akin to both genera and species from middle member of Xuannan formation and Sifangtai formation, so that they may belong to the same age late Late Cretaceous. Lower Tertiary deposits are widely exposed in Xuancheng, Nanling and Leian areas. These deposits are named as Shuangta group by Regional Survey Team, Geological Bureau of Anhui Province. According to its lithological characters and faunal assemblages, Shuangta group may be grouped into the following three members Brown-red or grey-brown sandstone containing fine grained conglomerate and ailtstone with fine grained conglomerate in the upper, purplish-red mudstone intercalated with fine-grained sandstone in the middle and purplish-red calcareous siltstone and silty mudstone in the lower member. The gastropod fossils are obtained from purpliah-red calcareous siltstone and fine-grained sandstone of middle member. Fossils of common and important occurrence are Theodoxus xuanchengensis Yii (sp. nov.), Bithynia loxostoma Wang (sp. nov.), Negulus amplinternatus Wang (sp. nov.), Pupoides (Ischnopupioides) antiquus Yii et Wang, Enteroplaxi luosigangensis Yii (sp. nov.), Prionolahium polytychium Yii (gen. ' et sp. nov.), Xuanchengospira flexilahrosa Yii (gen, et sp. nov.), Archaeozonites luosigangensis Yii (sp. nov.), Anhuispira granulifera Yii (gen. et sp. nov.), Oiffordius antiquus Wang (sp. nov.), Multiscapta raris Yii (gen. et sp. nov.), Ganeselloides sulcatus Wang (sp. nov.), G. latus Wang (sp. nov.), Undatornatus peregrinus Wang (gen. et sp. nov.), Crenatilabiellus profundus Wang (gen. et sp. nov.). Among them, the genus Ganeselloides is so far known from Middle Eocene Guanzhuang formation of Shandong. Ganeselloides latus is similar to genotype Ganeselloides marianus Yen from Guanzhuang formation. Pupoides (Ischopupoides) antiquus has originally been found from middle-lower parts of Funing Group in Jintan, and Shuyang, Jiangsu province. In general lower Bithynia loxostoma resembles Stalioa deschiensis Deshayes from Eocene in Europe. Theodoxus xuancheng- ensis is a more common element in Shuangta group of Xuancheng basin and closelj' related to Theodoxus (Theodoxus^) cryptospioides (Fontannes) from Sannoisian stage of Europe in general shape of shell. Opercula fossils in middle member of Shuangta group are same to those of Guanzhuang formation and quitely differ to those from Cretaceous of Montana, America. From the above statement, it becomes clear that the Shuangta fauna shows apparently closely related with the Guangzhuang fauna and the Funing fauna of Jiangsu. Therefore, the middle member of Shuangta group may belong to the Early- Middle Eocene. In Nanling Basin, the freshwater gastropods were first collected from the Lower Tertiary. The Physa yuanchiiensis Yii and Australorhis odhneri Yen have originally been found from-Hedi formation of Yuanchii basin, Shanxi, therefore their age is Late Eocene. ^s:^: ^mm&m^m^mE.mmmm&mit^ 27 DESCEIPTION OP NEW GENERA Genus Prionolabium Yu (gen. nov.) Type species: Prionolabium polyptychium Y\\ (gen. et sp. nov.) Diagnosis: Shell small, conical, apex obtusely rounded. Whorls narrow, gradual- ly increasing, 7—8 in number. Aperture narrow and oblique, lunate, peristome thick- ened and reflected. Parietal wall with 5 parietal lamellae; columellar lip thickened palatal folds 6. Umbiicus narrow. Surface ornamented with growth lines. and smooth ; Remarks: This new genus is similar to Agallospira Yii, 1977 in the elevated spire, in the rounded periphery, but the Agallospira distinguished in the wider aper- ture and in presence of 1 parietal lamellae and 2 palatal folds, as compared with the Prionolabium. Distribution: Early Tertiary, China. Genus Xuanchengospira Yii (gen. nov.) Type species: Xuanchengospira flexilabrosa Yii (gen. et sp. nov.) Diagnosis: Shell small, depressed conical, spire low, apex obtusely rounded, whorls narrow, 7—8 in number, gradually increase, with convexly rounded periphery. Aperture obliquely ovate, wider than high. Peristome reflected, with 4 parietal lamellae., 1—2 palatal folds and 5 basal folds. Surface ornamented with growth lines only. Remarks: In depressed conical shell, obtusely rounded apex and the form of aperture, the present new genus resembles Shanshuispira Yii et Zhang, but differs from the latter in the fewer parietal lamellae and basal folds. It also distinguished from the Prionolabium (gen. nov.) in the depressed conical shell, in the reduced parietal lamellae and in the form of the aperture. Distribution: Early Tertiary, China. Genus Anhuispira Yii (gen. nov.) Type species: Anhuispira granulifera. Yii (gen. et sp. nov.) Diagnosis: Shell medium in size, depressed conical, spire slightly elevated. Apex obtusely rounded. Whorls 7—8 in number, gradually increase in early whorls, rapidly in the last whorl, then slightly descending near the aperture, with rounded periphery. Suture rather impressed. Aperture ovate, peristome expanded and strongly reflected. Surface ornamented with granular spirals and growth lines. Remarks: In general form of the shell, this genus is closely related to Archaeozonites Sandberger, 1874, but easily distinguished from Archaeozowites by its roundly ovate aperture and by its granular spirals. Distribution: Early Tertiary, China. Genus Multiscapta Yii (gen. nov.) Type species: Multiscapta raris Yii (gen. et sp. nov.) Diagnosis: Shell small, broadly conical, spire rather high, apex elevated. Whorls 28 ^mn^^mp.mm^^^mnmmn m n ^ narrow, 7—8 in number tightly coiled, last whorl slightly descending, with roundly convex periphery. Aperture oblique, ovate — rounded, peristome thickened and strongly reflected, but abruptly constricted behind apertural margin 6—7 mm. and with 1 columellar lamella and 6—8 baso-palatal folds in the constricted zone. Remarks: In the general characters of the shell, this new genus is closely related to Thaumatophora Ancey, 1887, a recent genus described from Yangtze Kiver of China, but the Thaumatophora having 3 palatal folds, which extended to the apertural margin. Distribution: Early Tertiary, China. Genus Undatornatus Wang (gen. nov.) Type species: Undatornatus peregrinus Wang (gen. et ap. nov.)

Remarks: This genus has denticles similar to that of Metodontia, but it differs in its irregular undulate growth lines. In the known morphological features of shell, the new genus seems to be closely related to the genera of Bradybaenidae. Distribution: Early Tertiary, China. Genus Crenatilahiellus Wang (gen. nov.) Type species:. Crenatilabilellus profundus Wang (gen. et sp. nov.) Diagnosis: Shell conic, narrowly perforate, increasing slowly in size, aperture semicircular in outline, peristomal margin thickened and reflex, parietal lip with five denticles, opposite which outer lip bearing eight denticles.

LATE CRETACEOUS AND EARLY TERTIARY NON-MARINE GASTROPODS FROM SANSHUI BASIN, GUANGDONG Yii Wen (Nanjing Institute of Geology and Palaeontology, Academia Sinica) Zhang Xianqui (735 Geological Team, Geological Bureau of Guangdong) Abstract In South China, the Sanshui basin is commonly known to be one of the region where the Cretaceous and Early Tertiary Eed Series are well developed over a large extent and rich in fossils, such as ostracods, gastropods, pelecypods, insects, coricho- straca, flora, charophytes and spore. Based on the sedimentary characters and faunal assemblages. The Cretaceous and lower Tertiary series in this region may be divided in ascending order into: 1, Baihedong formation, 2, Sanshui formation, 3, Dalangshan formation, 4, Xinzhuang formation, 5, Buxin formation, 6 Baoyue formation and 7, Huayong formation, each of them being subdivided respectively into several members. The materials are obtained mostly in the Xinzhuang and Baoyue formations, minor in the Dalangshan and Buxin formations, rare in the Sanshui and Huayong formations and absent in the Baihedong formation. A total of 35 genera and 48 species and subspecies are here described with 6 new genera and 36 new species and subspecies included. CHARACTERS OF ASSEMBLAGES AND AGE OF THE FOSSILIFEROUS BEDS According to their stratigraphic distribution, 6 gastropod assemblages may be divided ascendingly as follows: ? 70 ^mn^^mp^mm^^mm^mmn %\m 1. This assemblage, the lowest one, dominated by the aquatic prosobranchians, is now known to occur only in the dark grey or brown-red siltstone and marly limestone of the middle member of Sanshui formation, containing Valvata sp., TruncateUa sanshuiensis (sp. nov.), Pyrgula? xijiangehins (sp. nov.), and Physa shakengensis (sp. nov.). The genus TruncateUa is widespread in the Early Tertiary strata in Asia, Europe, North Africa and Australia, which has also been found from the Upper' Cretaceous Paomagang formation of Hubei and from the Upper Cretaceous Xuannan formation of southern Anhui of China. The species TruncateUa sanshuiensis bears a closely similarity to TruncateUa maxima Yii et Lee from the Upper Cretaceous Sifangtai formation of Songliao Plain. Valvata sinensis Yii et Lee was first recorded from Sifangtai formation, then occurs from the Upper Cretaceous Xuannan forma- tion of southern Anhui. Therefore, the Saushui formation is referable to the Upper Cretaceous in age. 2, The gastropod assemblage of the Dalangshan formation is represented by the aquatic prosobranchians. The commonest forms are Valvata sp., Valvata (Cincinna) Shakengensis (sp. nov.), Reesidella striata (sp. nov.), Charydrohia pyrymis (sp. nov.), Parateinostoma turriculatum (sp. nov.), Physa shakengensis (sp. nov.) etc. Parateino- stoma turriculatum is similarity to Parateiniostoma manum (Tausch) from the Upper Cretaceous of western Hungary. Reesidella striata is closely related to Beesidella protea (Yen), which has been reported from the Upper Cretaceous Edmonton formation to the Palaeocene Paskapoo formation of Canada and from the Palaeocene Fort Union formation in Montana of United State. In consideration of these features, it appears that Dalangshan formation may be referable to late Late Cretaceous. 3, In Xinzhuang formation, the gastropods occur chiefly in the brown-red, dark red fine-grained sandstone and dark grey siltstone in the middla-upper members of this formation. This assemblage is preponderated by land snails, such as Sanshuispira multilamella (gen. et sp. nov.), Gracillinoconcfui multiptychia (gen. et sp. nov.), Geotthchus^ xinanensis (sp, nov.), Protostreptaxis obliquus (gen. et sp. nov.), lAmonohelix corrugata (gen. et sp. nov.), L. filaris (gen. et sp, nov.) and L, tetralamella (gen. et sp, nov.) etc. Most of them are new genera and forms, but they occur in association with ostracods, such as Eucypris sanshuiensis Zhang, Sinocypris lenticulata Zhang and Parailyocypris changzhouensis Yang et Hou etc. Therefore, their age probably belongs to the Palaeocene-Eocene. The first appearance of the land snail assemblages in this region is of very importance for it affords us not only the fossil evidence on the geological age, but also the geographic distribution of Early Tertiary land snails in South China. 4, The Buxin formation consists mainly of dark grey siltstone and marly limestone, jrielding aquatic prosobranchians and a few land snails, namely, Bellamya heijiangen- sis (sp. nov,), Lioplax honggangensis (sp, nov.), Parhydrohia ornata (sp, nov,), Lymnaea dalangshanensis (sp. nov.), Pletirodiscus bellus (sp. nov.), and Pupoides sp. Among them Lioplax honggangensis resembles Lioplax quananensis Yii from the Early Eocene Luofozhai formation of the Nanxing basin of Guangdong, The species Parhydrohia ornata is closely related to Parhydrohia macilenta Yii from the Early- Middle Eocene Funing group of Jiangsu. The fossil-bearing deposits seem to be Early Eocene, 8 ^txw: riR^7K^mm&mi^m^m^^^mmm&mt^ 71 5. The gastropod assemblage of Baoyue formation contains 13 genera and 23 species, accounting for one-half the total of the fauna. Among the leading forms are Hydrolia nanhaiensis (sp. nov.), By thinella lecongcnsis (sp. nov.), Bithynialordostoma Yii et Wang, B. cf. magna Yii et Wang, Gyraulus cf. gaoyouensis Yii, Strohilopsi stenostoma (sp. nov.), Discostrohilopsf incerta (sp. nov.), Succinea haoyueensis (sp. nov.), Brachyspira suhsphaerica, Archaeozonites luosigangensis minleensis (subsp. nov.), Bellornatus trochiformis (gen. et sp. nov.) and Janulus decorosus (sp. nov.), etc. These forma are represented by the numerous genera and species of land snails, a feature suggesting that during the time when the Baoyue formation was formed, the water body was usually shallow, having many hilliness and a well-rivered region. Under the favorable condition, these land snails were able to bring into existence and develop flourishingly. Therefore, the gastropod assemblage in this formation is of great importance from the evolutionary point of view. The species Bithynia lordostoma has commonly been recorded from the middle-upper formations of Funing group of Jiangsu, and from the Early Eocene Luofozhai formation of Nanxiong basin of Guang- dong. Bithynia magna and Gyraulus gaoyouensis have also been found from middle- upper formations of Funing group. Besides, Strobilops? stenostoma and Discostrohilopsf incerta agree in many respects with Multiscapta raris Yii and Strohilops multiden- ticulata Wang from the middle member of Shuangta group of South Anhui. There- fore, the fossil-bearing deposits are referable to Middle Eocene in age. 6. The Huayong formation is composed of purplish grey or brown-red sandstone containing conglomerates, fine-grained sandstone, intercalated with dark grey or brown- red siltstone and volocanic rocks, containing Amnicolal sp., Physa sp., Au^tralorbis sp., Pupoides sp., and Nanhaispira eversilabia (gen. et sp. nov.), etc. The genus Australorhis is widely distributed in many parts of world. It is known in the Eocene of western Europe, in the Bridgerian formation of Nouth America, etc. In China, it has been commonly reported from the Late Eocene in North China, while in South China, it can be seen chiefly in Linjiang formation of Jiangxi, in Xialiushi formation of the Hengyang basin of Hunan and in the Eocene of Yunnan, etc, consequantly, the gastropod-bearing deposits belong probably to the Late Eocene.

In accordance with the features of these gastropod fossils, the paper has discussed the distribution and comparisons of the gastropod fossils. It has also discussed that the geologic period of the Anyuan for- mation from the Chengtanjiang district, Liuyang, Hunan should have belonged to the Late Triassic, and the of the Guanyintan formation, Dabakou member in the Lingling district Hunan and of the Baling formation in Guangxi may have belonged to the Early Jurassic. Besides, in accordance with the living habits of the gastropods belonging to the Dabakou member and the Baling series, the paper has also discussed the characteristics of the sedimentary environment of this period. The diagnosis of the new genera are given below Genus Fascivalvata Pan (gen. nov.) Diagnosis: Shell minute, subdiscoidal in outline, having 3—4 whorls rapidly increasing, with depressed and slightly elevated spire, whorl with a conspicuous spiral carina at upper surface, the surface of the shell bearing distinct growth cords, suture generally deep, perforate. Type species: Fascivalvata minuta Pan (gen. et sp. nov.) Age and distribution: Triassic; Hunan and Jiangxi, China. Genus Linglingella Pan (gen. nov.) Diagnosis: Shell small in size, subglobose in outline, obtuse apex and low spire, whorls about 3 rapidly increasing and strongly convex dilated body whorl. Suture shallow, base roundly convex, anomphalous. Aperture oblique, subovately shaped. The sculpture consists of fine growth lines or obscure growth costae, with row of small nodes just below the upper suture at early whorls, bearing a distinct spiral carina or round angulation at outer-upper edge of the whorl near the aperture. Type species: Linglingella nodusa Pan (gen. et sp. nov.) Age and Distribution: Jurassic; Hunan, China, Genus Nannobesa Pan (gen. nov.) Diagnosis: Shell minute in size, subglobose in shape, broader than high, obtuse apex, low and slightly elevated spire, slowly increasing at early whorls and rapidly increasing body whorl, subdiscoidal. Suture shallow, base convex and anomphalous. Aperture semilunar in outline, roundly angled above and round below. The surface is covered by fine lines of growth. Type species: Nannobesa globosa Pan (gen. et sp. nov.) Age and Distribution: Jurassic; Hunan, China. Genus Pericarinata Pan (gen. nov.) Diagnosis: Shell minute in size, ovally conical, slightly convex whorls, lower side of the whorl bearing a strongly sharp peripheral carina in the nepionic stage and outer side of the whorl is flat concave, forming a spiral depression, peripheral carina roundly angled at the lower side of the whorl in ephebic stage, roundly angled shoulder, deep suture, convex base, anomphalous. Aperture nearly pyriform. The surface is ornamented by distinctly fine growth lines and irregularly coarse growth lines. Type species: Pericarinate hicarinata Pan (gen. et sp. nov.) Age and Distribution: Triassic; Hunan, China. Genus Hunania Pan (gen. nov.) Diagnosis: Shell small in size and thick substance, narrowly pyramidal to high- conic in outline, whorls about 10, broader than high of the whorls, suture deep or groove. The ornamention of the shell consists of distinctly fine spiral lines and strong riblets, which are small nodes at apical end, the interspace between two riblets is con- cave, bearing conspicuously fine spiral lines and fine growth lines, base slightly convex and absenting spiral lines, riblets obscure, anomphalous. Aperture ovate-oblong in shape, angular above, round below, coUumellar smooth and nearly straight. Type species: Hunania lanshanensis Pan (gen. et sp. nov.) Age and Distribution: Jurassic; Hunan and Guangxi, China. Genus Trianglaspira Pan (gen. nov.) Diagnosis: Shell small in size, roundly-ovate to conically ovate in outline, having 4—5 whorls, Apex sharp and spire conical, the early whorls increase slowly, but the last whorl is rapidly and distinctly dilated, subcircular. Suture distinctly visible, near aperture bearing a strongly sutural groove, upper side of the aperture having a slightly convex triangular area, base convex, anomphalous or umbilical fissure. Aperture ovate-oblong in shape, the smooth surface is ornamented by fine spiral lines and fine growth lines. Type species: Triangliaspira secta (gen et sp. nov.) Age and distribution: Jurassic; Hunan, China. Subgenus Bulbusoides Pan (subgen. nov.) Diagnosis: Shell small, subglobose in outline, with a short small spire nnd subglobose body whorl, base convex, with distinct umbilicus, suture shallow, aperture high and large, nearly roundly ovate in outline, the peristome is simple, the outer lip is twisted, and the parietal lip is oblique, collumellar lip near straight, the surface of the shell is covered by strong lines of growth.

The layer of rocks from bottom upwards are "Red bed" Formation, Weizhou group, Xiayang formation, Jiaowei formation, Foluo formation, Wanglougan forma- tion and Quaternary. The Cretaceous, Carboniferous or Cambrian metamorphosed rocks underlies the Cenozoic strata. "Red bed" formation did not consist fossil and its age probably is Cretaceous to Palaeogene. "Weizhou group is divided into the lower subgroup and the upper subgroup : The lower subgroup consists of red silty sandstone and contains fresh water and land of gastropods living on dry land and opercula which are Assiminea retopercula Wang, Mirolaminatus gracilis Wang and Enteropaxi Ivhsigangensis Yii. According to these fossils, the lower subgroup is determined to be of Eocene age. The palaeoclimate in that time was similar to that in the northern and eastern parts of our country. The upper subgroup is marked by green-grey and variegated silty sandstone and is charac- terized by marine and nonmarine gastropods as Turbonilla {Pyrgiscus) malayana Fischer, Stenothyrella roh ustostriata (sp. nov.), Stenothyra nonhasicostata (sp. nov.), Gangetia altaperta (sp. nov.) and Austraolaxispira minuta (gen. et sp. nov.), the age of the subgroup is of Oligocene. This age assignment is based on the close resem- blance of species from Oligocene of Bohai Sea Gulf. Xiayang formation consists of grey, grey-white grained sandstone. A few gastropods obtained from individual locality are Apollon (Biplex) perca (Perry), Clavus (Drillia) tjibaliungensis (Martlin), Cythara suboestata var. Strausz and Hastula homale Woodring. According to these fossils, the formation is marine Miocene. Jiaowei formation of rock types include grey-gi*een and dark-green silty slight sandstone, in which merely Pusia {ExilipMsiolina) micra (subgen. et sp. nov.) and Carinodrillia^ infantilis (sp. nov.) are found. The age of the formation can only be determined by the age of overlying and underlying formation. Foluo formation consists prodominently of yellow-green sandstone and contains abundant Limacina hainanensis (sp. nov.) and Actcocina heraclitica Berger, Ringicula ohesior Marwick, Odostomia (0.) hilgendorfi dbnorma Nomura, Seila trilinea Phil. The genus Limacina is living in warmer and rather deep sea. The geologic age of this formation is Miocene, similar to Messinian. Wanglougan formation is composed by grey, grey-green slight sandy siltstone, in -which abundant gastropods of tropid type were found. The age of the formation is considered to be of Pliocene. The environment of this formation is similar to that of today. The Quaternary bed consisting of shale, basalt or pebble seems were found to have been nonmarine sediment in which only one kind of nonmarine gastropod Fluviopupa micra (sp. nov.). Genus Paracirculus Wang (gen. nov.) Diagonsis: Shell smaller, nearly disk-shaped. "Whorls round. Spire low, but it rising a little above the last whorl. Surface ornamented by spiral lines or carinae. Umbilicus prominent and encircled by smooth carina. Aperture round or round oval and not loose. Type species: Paracirculus parvumbilicatus Wang (gen. et sp. nov.) Genus Australolaxispira Wang (gen. nov.) Diagonsis: The shell is small, slender, fusiform, strong axial ribs and subsuture band on the surface. Aperture loose on the adult shell. Type species: Australolaxispira minuta Wang (gen. et sp. nov.) Genus Xuwenospira Wang (gen. nov.) Diagonsis: Shell smaller subdisoidal. Spire depressed conical but slightly below the last whorl. Last whorl increasing rapidly in size, angulated at the periphery. Aperture wide, rhombic. Umbilicus wide, but shallow. T3T>e species: Xuwenospira rara Wang (gen. et ap. nov.) Genus Pusia Swainson, 1840 Subgenus Exilipusiolina Wang (subgen. nov.) Diagonsis: Shell small, fusiform, axial ribs on the postconch. A strong triangular prominence on the upper part of columellar lip ; a round prominence on the inner surface above the middle part of the outer lip. Type species: Pusia (Exilipusiolina) micra Wang (subgen. et sp. nov). Genus Sexlamellospira Wang (gen. nov.) Diagonsis: Shell depressed conic, round at the periphery. Aperture lunar, six parallel parietal laminae on the parietal lip, which obliquely extended; parallel short spiral goove on the outer lateral surface of the outer lip.
