Abstract

Atlanticus Scudder illustrates a disjunctive distribution comprising 1 subgenus and 10 valid species from eastern North America and 2 subgenera and 14 valid species from eastern Asia. Several authors also predicted that it would appear that China was rich in new species of the genus Atlanticus. Based on investigation of male stridulatory apparatus, as well as previously used characters, including male and female abdominal apex and measurements of various structures, we present a taxonomic account of 43 species of Atlanticus from China. Twenty-seven species of Atlanticus new to science are described. Erroneous synonyms are noted, based on examination of topotypes. Atlanticus changi Tinkham, 1941 and At- lanticus pieli Tinkham, 1941 are valid species and not synonyms of Atlanticus kiangsu Ramme, 1939. Atlanticus jeholensis Mori, 1935 is also valid and not a synonym of Atlanticus sinensis Uvarov, 1924. Moreover, the supposedly important character, i.e., length comparison between male pronotum and tegmen, is not suitable for differentiating two subgenera of Atlanticus, because it is easy to cause confusion. In contrast, the architecture of the male tegmen is a useful character to differentiate the two subgenera. The previous mentioned Species Groups and the corresponding descriptions are also studied. Necessary illustrations are provided.

Introduction

Atlanticus was described for three species Decticus dorsalis Burmeister, Decticus pachymerus Burmeister, and Atlanticus gibbosus Scudder by Scudder (1894). It is characterized by the sharply pronounced lateral carinae of pronotum, prosternum armed with two erect spines, ventral surface of the hind femora with four terminal spines, and the short inner tooth of male cercus (Scudder 1894). Kirby (1906) designated Decticus pachymerus Burmeister as its type species. Subsequently, several authors including Rehn & Hebard (1916), Davis (1915), and Hebard (1934) provided transfers and described new species of Atlanticus from eastern North America. Some others including Uvarov (1924, 1926), Mori (1936), Ebner (1939), Ramme (1939), Tinkham (1941), Bei-Bienko (1951, 1955), Zheng and Shi (1999) and Du and Shi (2005) described some new species and provided new transfers from eastern Asia. Until now, there have been recorded two subgenera twenty-four valid species in the world. They are distributed with one subgenus and ten species occuring in eastern North America and two subgenera fourteen species in eastern Asia. In addition, both Uvarov (1924) and Tinkham (1941) also stated that eastern Asia must possess further new species unknown to science. Presently, the taxonomic status of species in the Atlanticus requires clarification. In Rehn & Hebard’s excellent monograph (1916), the North American species were divided into four groups, based on the size, lateral margin of pronotum, degree that male tegmina are concealed under pronotum, shape of male cercus, and female ovipositor. Tinkham (1941) divided the eastern Asian species into six species groups, based on characteristics of male tegmen, male cercus and ovipositor. Ramme (1939) considered Atlanticus ussuriensis Uvarov, 1926 in Tinkham’s Palpalis Group as type species to establish the genus Paratlanticus. Bei-Bienko (1955) divided the genus into two subgenera based on the differences on the length comparison between male pronotum and tegmen, shape of female ovipositor apex, and female subgenital plate; however, he didn’t discuss the relationship between the subgenus and the species groups in Tinkham (1941). Among the species distributed in China, four belong to the subgenus Atlanticus, seven belong to the subgenus Sinpacificus, and two species are not ascribed to any subgenus in Eades et al. (2013); however, the ascription needs to be carefully checked. Additionally, one of the initially proposed characters used to differentiate the two subgenera of Atlanticus, i.e., length comparison between male pronotum and tegmen, is not useful because utilization of the character is easy to cause confusion.

2 · Zootaxa 3647 (1) © 2013 Magnolia Press LIU At the same time, validity of several species still requires reconfirmation. Bei-Bienko (1955) considered A. karnyi Ebner, A. pieli Tinkham and A. changi Tinkham as synonyms of A. kiangsu Ramme, and A. jeholensis Mori as synonym of A. sinensis Uvarov. But he didn’t examine the types or topotypes of A. kiangsu, A. jeholensis or A. sinensis. Notably, Rehn & Hebard (1916) proposed that Atlanticus in America is of austral origin, centre of distribution being in the south-eastern part of the United States. After recording three species from Eastern Asia, Uvarov (1924) indicated, the circumstance that the whole subfamily is a very ancient group and undoubtedly a relict of some widely distributed fauna should be emphasized when speculating the reasons of the two entirely disconnected regions. After recording nine eastern Asian species, Tinkham (1941) inferred that Atlanticus might have penetrated into North America from Asia since Glacial times like the genus Metrioptera, or persisted in both Asia and North America because of their adaptations to a more rigorous climate like the Holarctic genera since Glacial times. Additionally, the species in Atlanticus can give loud sounds, but male stridulatory apparatus and male stridulatory file have not been studied. Herein, I examined numerous materials collected from China including several topotypes. I studied the male stridulatory apparatus including male stridulatory file, as well as previously used characters. I present a taxonomic account about this unusual genus and unveil the species distribution patterns in China. I redescribe the two subgenera, provide the description and inclusion of five species groups mentioned in Tinkham (1941), and presented description of 27 new species, and redescription of some known species. The total number of Atlanticus species is now 44 in eastern Asia, among which 43 are in China, and 10 in the rest of the world. This will provide new clues of the origin of the genus. The terminology used is that of Tinkham (1941) and Rentz and Colless (1990). The examined specimens come from Collection of Institute of Zoology, Chinese Academy of Sciences, Beijing, China (IZCAS).

Description. Scudder (1894); Rehn & Hebard (1916); Tinkham (1941). Redescription. Fore femur longer than pronotum. Fore and middle tibiae dorsally with a subapical spine only on one side, exterior in fore tibiae and interior in middle ones. Female tegmen micropterous. Ovipositor somewhat recurved in Asian species, but decurved in most North American species. Notes. The present taxonomic account is based on the material collected from China. The Asian species of Atlanticus are variable in body size, length, shape and vein structure of male tegmen, male tenth abdominal tergum, male cercus, and shape, length, width of female ovipositor. According to the variance, they were divided into six species groups in Tinkham (1941). Nonetheless, American species of Atlanticus are variable regarding the presence of spines on the prosternum, divergence degree of lateral carinae on disc of pronotum, shape of caudal margin of disc of pronotum, length of medio-internal spur of hind tibia, and especially the curvature of the ovipositor. The genus was divided into four groups in Rehn & Hebard (1916). Thus, it is essential to also re-examine species distributed in North America to give a detailed redescription; however, the material of those species was not available at this time.

Proximal three quarters of stridulatory file of male left tegmen with 68 distinct teeth gradually becoming larger centrad (Fig. 1A). Proximal one third part of mirror of male right tegmen covered by pronotum (Fig. 2A). Female ovipositor robust (1.9 mm wide in middle), twice as long as pronotum, with moderately recurved apical half (about 15º angle) (Fig. 7E). Proximal one third of ovipositor narrowed from base, remainder of equal width, with upper margin slightly obliquely truncate in apex. Notes. One male paratype collected from Haichou, Kiangsu province is not A. kulingensis. It is possible that Tinkham (1941) possessed only one male specimen which had male cerci that resembled those of A. kulingensis. Actually, A. kulingensis distinctly differs from the material from Haichou, Kiangsu province by shape of the pronotum and ovipositor (see below). Distribution. China (Jiangxi).

4 · Zootaxa 3647 (1) © 2013 Magnolia Press LIU Notes. The type or topotype is not available. According to the original description, male tegmen of the species is much shorter than the length of the pronotum, and the posterior margin is rounded and the tegmen bears rudimentary veinlets. Furthermore, its male cerci are similar to those of A. (A.) kulingensis. Consequently, the species is temporarily ascribed to the Kulingensis Group. Obviously, it is erroneous that Eade et al. (2013) put the species into the subgenus Sinpacificus, based on the characteristics aforementioned. Distribution. China (Anhui).

One male paratype [No. IOZ(E)361919] possesses different characters from the holotype including male stridulatory apparatus, length of tegmen and coloration (Fig. 1E; 2E; 3E; 4E; 7H; 9E). Proximal three-quarters of stridulatory file on underside of male left tegmen with 52 distinct teeth gradually becoming larger centrad. Most of mirror of right tegmen concealed by pronotum. Notes. This new species belongs to the Kulingensis Group of Tinkham (1941), based on the structure of male cercus. It differs from A. kulingensis by its robust shape, shape of pronotum and its tegminal structure. The aforementioned male paratype possesses significantly different characters, indicating that it might be a different species. I reservedly consider it as variation of the new species for there is only one specimen at hand. Further investigation is needed to provide an accurate identification. Etymology. The new species is named for its type locality. Distribution. China (Shandong).

(A.) parabeitaii sp. n.; A. (A.) abeitaii sp. n.; A. (A.) beitaii sp. n.; A. (A.) zhouzhii sp. n.; and A. (A.) wudangensis sp. n.. Notes. Bei-Bienko (1955) considered A. jeholensis Mori as synonym of A. sinensis Uvarov. Actually, the holotypes of A. jeholensis and A. sinensis, were separately collected from Wulingshan in Hebei Province, and Taibaishan in Shaanxi Province; however, Bei-Bienko (1955) examined material only collected from Yangjiaping in Hebei Province and drew the conclusion. Herein, after examining one female topotype of A. sinensis and three male specimens collected from Yangjiaping, and checking the original literature and illustrations of types in Otte et al. (2013), I think that the material from Yangjiaping should not be identified as A. sinensis. So it is necessary to temporarily resume the validity of A. jeholensis, awaiting further investigation of the type or topotypes of the two species.

32 · Zootaxa 3647 (1) © 2013 Magnolia Press LIU Diagnosis. Large-sized compared to the congeners, but slightly smaller than A. (S.) magnificus Tinkham (Fig. 8J, K; 10B). Male tegmen amplified, broadened, deepened, extending to the eighth abdominal tergum, with clear longitudinal and cross veins; flat dorsal and lateral planes at right angles to each other; lateral plane deepest in apical quarter (Fig. 8J; 10B). Male cercus of moderate length, robust, heavy of equal width to a subapical internal tooth situated in upper surface in apical one third, and then strongly constricted and gently incurved with a bluntly pointed tooth (Fig. 3V). Description. Holotype. Male. Disc of prozona slightly convex, and metazona approximately flat. Pronotum narrowest in proximal quarter, and then gradually ampliate caudad. Lateral lobes of pronotum deepest at middle; anterior margin very slightly concave, posterior margin oblique with a very indistinct central concavity, ventral margin aslant caudad to posterior angle. Tegmen with radial vein branching out two stems in apical half, median vein similar to that of A. (S.) magnificus. Stridulatory file of left tegmen with 110 distinct teeth gradually becoming larger centrad (Fig. 5B). Length of mirror (Fig. 6B) on right tegmen wider than long, and secondary mirror longer than mirror [Mirror length and width (3.5mm, 4.5mm); greatest width of secondary mirror (7mm); smallest width of secondary mirror (5 mm)]. Fore femora without spines. Middle femur with 1 external ventral spine in apical half. Hind femur with 2 exterior and 5 interior spines on ventral margins. Fore tibia with 3 dorsal spines on exterior margin and 6 ventral spines on both margins. Middle tibia with 6 ventral spines on both margins, 2 exterior and 4 interior spines on dorsal margins. Hind tibia with 20 exterior and 18 interior spines on dorsal margins. Ninth abdominal tergum with a minute “U”-shaped central notch. Tenth abdominal tergum with a large central “U”- shaped cleft (Fig. 4U). Subgenital plate with a wide “U”-shaped notch between styli, notch slightly shorter than stylus (Fig. 11U). Female (Fig. 8K). Tenth abdominal tergum with a central “U”-shaped notch. Cercus conical, with obtuse apex. Ovipositor long, straight, apical one third recurved, with apex obliquely truncate. Subgenital plate distinctly transverse, emarginate in apical half, forming two obtuse triangular lateral lobes. Coloration. Overall color reddish dark brown. Outer surface of two basal antennal segments, segments, fastigium frontis, front and lateral surfaces of fastigium verticis, postocular fascia shining black. Disc of pronotum dark brown; parallelogram-shaped area composed of ventral margin and ventral two thirds of posterior margin in lateral lobes extending upwards to almost touch lateral carinae yellowish brown, remainder below lateral carinae shining blackish brown. Fore femora, posterior and ventral surfaces of fore tibiae, fore tarsus blackish brown. Pale brown median femora with a row of dark brown dots on upper one third of anterior surface, and two rows of dark brown spots on posterior surface; pale brown median tibia with a row of dark brown dots on upper half of anterior surface, blackish posterior surface and brown dorsal surface. A robust dark brown line with indefinite striation separated the upper half from the lower half on posterior surface of hind femora. Tegmen reddish brown. Both lateral margins of visible abdominal tergite with with black striation. Abdominal sternites bright yellow. Notes. The species is put into the Magnificus Group in Tinkham (1941), due to large, broad and deep tegmina of male, and very long and practically straight ovipositor. It differs from A. magnificus, by possessing a comparatively narrow and elongate pronotum, comparatively narrow and short tegmen, comparatively small average mirror, comparatively short secondary mirror [Atlanticus magnificus: Mirror length and width (3.5mm, 5mm); greatest width of secondary mirror (8mm); smallest width of secondary mirror (7mm)], and structure of male tenth abdominal tergum and male cerci. The new species resembles A (S.) kwangtungensis Tinkham and A. (S.) hoffmanni Tinkham in Palpalis Group with similar male cerci, but distinctly differs in the shape of male tegmen. It also differs from A. (S.) hoffmanni by much longer ovipositor. It differs from A. (S.) palpalis Rehn & Hebard in the Palpalis Group by the shape of male tegmen, male cerci and much longer ovipositor. Etymology. The new species is in honor of Dr. Le Kang for his great contribution to the entomology. Distribution. China (Guangxi).

The following parts greyish brown: head with exception of a blackish postocular fascia, disc of pronotum, and each femur except for one central dark brown stripe separating upper and lower portion of hind femur. Ventral pines on hind femur black. Male unknown. Notes. The new species most resembles others in the Magnificus Group in the general shape of pronotum, ovipositor and subgenital plate. It differs from others in some specifics including length of female tegmen, hind femora and ovipositor. Consequently, we temporarily put it into the Magnificus Group, but its true placement can be determined not until its male has been discovered. Etymology. The new species is named for the type locality—“living space for fairies”. Distribution. China (Fujian).

Pieli Group

Tinkham, 1941. Notes Ent. Chinoise 8(5):215.

Description. Tinkham (1941). Notes. After examining two males collected from Tianmushan mountain in Zhejiang province, and two females collected from Lushan in Jiangxi province, Bei-Bienko (1955) identified them as A. kiangsu Ramme. Thus, he considered that A. karnyi Ebner (type locality: Zhejiang Province), A. pieli Tinkham (Type locality: Tianmushan mountain) and A. changi Tinkham (Type locality: Lushan mountain) were new synonyms of A. kiangsu. However, the type locality of A. kiangsu is Shanghai, distant from the Tianmushan, and especially Lushan mountains. That it is, Bei-Bienko (1955) did not examine type or topotypical material of A. kiangsu. After examining topotypis of A. kiangsu, A. pieli, and A. changi, I found that distinct differences occur among these three species, including structure of male tegmen, male stridulatory apparatus and male tenth abdominal tergum. However, the female ovipositors of the three species are only slightly different in details. Lacking precise type locality details, I am unable to find topotypes of A. karnyi. By comparing the original description of A. karnyi, I judged that it is very similar to A. pieli. Obviously, the inference about the synonyms of three species in Bei-Bienko (1955) is not reasonable. Consequently I temporarily consider that A. changi, A. pieli and A. karnyi remain valid. Examination of type or a topotype of A. karnyi is very essential in making a decision in this regard. Notably, one

Atlanticus pieli Tinkham (1941) was described based on male holotype from Tianmushan mountain in Zhejiang Province. Bei-Bienko (1955) considered it a synonym of A. kiangsu. However, after comparing topotypical material of the two species, I conclude that they differ from each other in the shape of the male stridulatory region and stridulatory file. Additionally, after examining one male paratype of A. pieli collected from Shanghai, I considered that it should be identified as A. kiangsu. Distribution. China (Zhejiang).

40 · Zootaxa 3647 (1) © 2013 Magnolia Press LIU Female. Tenth abdominal tergum with a slight central “U”-shaped notch. Cercus conical, with obtuse apex. Ovipositor moderately straight, one and a half times the length of pronotum; apical half recurved with apex obliquely truncate. Apical margin of subgenital plate with a very obtusely angular tiny emargination. Coloration. Generally dark reddish brown. The following parts shining black: the outer surface of two basal antennal joints; lateral surfaces of fastigium verticis; postocular fascia; lateral lobes of pronotum except a comparatively narrow fascia along the ventral margin; upper three quarters of posterior surface of fore femur, and posterior surface of fore tibia and fore tarsus; posterior surface of median legs and median tarsus; proximal upper margin of hind femora; a robust line with indefinite striation separated the upper half from the lower half in central one third part on anterior surface of hind femora; basal half radial areas between radial and subcostal veins of male tegmen. Ventral interior spines of hind femur black. Variation. Two male paratypes possess much shorter wings than the holotype. However, all these specimens possess very similar male stridulatory apparatus. So we temporarily consider them as one species. Notes. This new species differs from the congeners in Pieli Group by the mirror of male right tegmen and the shape of cleft of male tenth abdominal tergum. Etymology. The new species is named for the type locality. Distribution. China (Anhui).
