ABSTRACT Inatwo-yearstudy of thefamily Parastenocarididae in the River Krishna at Vijayawada,South India, vespecies belonging to the genus Parastenocaris Kessler,1913, have been met with. Of these,three are new to science: P. gayatri n. sp., P. savita n. sp., and P. sandhya n.sp.The rsttwo ofthesebelong to the brevipes-group,the last one to the sioli-group.This paper gives an illustrated descriptionof thesenew taxa, and also brie y discussestheir af nities and ecology. The other two species,viz., P.curvispinus Enckell,1970, and Parastenocaris sp.,will be dealtwith elsewhere. This isthe rstreport on Parastenocarididae from India. Incidentally,it has also been found that parastenocaridids constitute a ratherfavoured item in thediet of the postlarvae of a commerciallyimportant gobioid sh, Glossogobiusgiuris (Hamilton, 1822).A briefnote of this ndinghas been made.

Aidedby their minute,vermiform body and short limbs, theycan crawl orswim freely in the capillary system ofthe interstices betweensand grains. Thefamily Parastenocarididae contains about200 species in vewell-recog- nizedgenera: Parastenocaris Kessler, 1913, Forcatocaris Jakobi,1969, Parafor - catocaris Jakobi,1972, Potamocaris Dussart, 1979,and Murunducaris Reid, 1994. Of these, Parastenocaris is the most speciose genusand has aworld-widedistribu- tion,whereas all othergenera, containing few species, are exclusively Neotropical (Reid,1994). The family is ‘primarily freshwater’and only about a dozenspecies inhabit marine andbrackish coastal subsoil water (Wells, 1986).In the wholeof Asia, onlyabout 20 species haveso far beenrecorded (see Dussart &Defaye, 1990),but, surprisingly, none from India, as conrmed by H.K.Schminke(pers. comm.). Inthe courseof a two-yearstudy of parastenocaridids ofthe River Krishna at Vijayawada,I havecome across vespecies, viz., Parastenocaris gayatri n. sp., Parastenocaris savita n. sp., Parastenocaris sandhya n. sp., Parastenocaris curvispinus Enckell,1970, and Parastenocaris sp.The three newspecies will bedescribed below; accounts of the othertwo species foundwill bepublished elsewhere. STUDY AREA TheRiver Krishnais oneof the major rivers ofIndia. Originating near Mahabaleswarat analtitude of1360 m in the Western Ghatmountains, only about60 km from the ArabianSea, the river owsacross almost the entire peninsularIndia from the west to the east overa distance ofapprox. 1300 km beforedischarging into the Bayof Bengal. It enters the sea bytwoprincipal mouths andhas built upa large,very fertile delta continuouswith that ofthe Godavari River to the northeast.In the deltaic region,numerous arti cial habitats suchas tanks,ponds, canals, etc., are fedby the river.Theriver derives its water from the monsoonrains andhas several tributaries, ofwhich the Bhima (north)and the Tungabhadra(south) are the largest ones.It has acatchment area ofabout 233,229 km2. At the headof the delta at Vijayawada(16 ±310N 80±E)there is animportant barrage,named Prakasam Barrage,which was constructedin 1955for regulating the owof water in asystem ofirrigation canals, andwhich is situated 80km from the river mouth.The river narrowsbetween two hills ofgneiss andthen spreads PARASTENOCARIDIDAE FROMINDIA 707 overalluvial plains. Thechannel there is 1.2km wide.During summer, the river, downstreamof the barrage,becomes a narrowstream, with depthsbarely reaching 1.5m. Thedepth, however, rises to as muchas 13m during oodingtimes. Thesampling site at Vijayawadais located nearthe southernend of a road- bridgeacross the river,called KanakaDurga V aradhi,about 2.5 km downstream ofPrakasam Barrage.Here the river bedhas adeposit of nesand and detritus particles, butwith little ornoclay,andis almost devoidof macrophyticvegetation. Purefreshwater conditionsprevail throughoutthe year.During the present study, anunprecedented oodwas witnessed in the monthof October, 1998, which causedserious damageto the benthiccommunities. Thetemperature regime was: air 30-38±C,water 28-35 ±C. METHODS Coresamples wereregularly collected oncea monthfor two consecutive years, i.e.,January 1998 to December1999, using plastic tubes of70cm lengthand 4 cm diameter. Onafewoccasions, a metal corerwas also employed.Moist, exposedas well as submergedparts ofthe riverbedwere sampled. Each time, sampling was doneat vesites in c.100 m 2,andat eachpoint about ten cores weretaken from the sediment surface to adepthof 10-30cm, pooled into a bucketand vigorously stirred with ltered habitat-water.Thesupernatant was ltered througha plankton net madeof bolting silk (mesh size 70 ¹m).The ltrate was then xedin 10% formalin andpreserved in a5%formalin solution.A fewsamples werealso xed in 20%alcohol and preserved in 70%alcohol.

[email protected] 1. Brief definition of the group and main diagnosing characters The Harpacticoida is one of the orders of the subclass Copepoda, and includes mainly free-living epibenthic aquatic organisms, although many species have successfully exploited other habitats, including semi-terrestial habitats and have established symbiotic relationships with other metazoans. Harpacticoids have a size range between 0.2 and 2.5 mm and have a podoplean morphology. This morphology is char- acterized by a body formed by several articulated segments, metameres or somites that form two separate regions; the anterior prosome and the posterior urosome. The division between the urosome and prosome may be present as a constriction in the more cylindric shaped harpacticoid families (e.g. Ectinosomatidae) or may be very pronounced in other familes (e.g. Tisbidae). The adults retain the central eye of the larval stages, with the exception of some underground species that lack visual organs. The harpacticoids have shorter first antennae, and relatively wider urosome than the copepods from other orders. The basic body plan of harpacticoids is more adapted to life in the benthic environment than in the pelagic environment i.e. they are more vermiform in shape than other copepods. Harpacticoida is a very diverse group of copepods both in terms of morphological diversity and in the species-richness of some of the families.

E-mail: [email protected] Abstract A new species of harpacticoid, Parastenocaris distincta sp. nov., is described and discussed. The new species was collected in a freshwater interstitial habitat near the mouth of a river in Western Mindoro Province, the Philippines. This is the second species of Parastenocaris described from this country. The medial ornamentation of P1 basis, the morphology of male P3 and the number and distribution of the integumental pores in the new species differ from those previously reported in other species of Parastenocaris. We review and discuss the more common arrangements of these features in recently described species, emphasizing the taxonomic discriminative value of their variations. Key words: Parastenocaris, Philippines, interstitial habitat, Harpacticoida, groundwater Introduction The harpacticoid family Parastenocarididae Chappuis is composed of seven genera: Parastenocaris Kessler, Forficatocaris Jakobi, Paraforficatocaris Jakobi, Remaneicaris Jakobi, Potamocaris Dussart, Murunducaris Reid, Simplicaris Galassi and De Laurentiis. All of them are exclusive to freshwater subterranean waters, Paraforficatocaris, Forficatocaris, Potamocaris, and Murunducaris are neotropical with a more or less limited distribution, Remaneicaris is neotropical with a wide distribution (Corgosinho & Martínez Arbizou 2005), Simplicaris has very restricted distribution being known only for Central Italy (Galassi & De Laurentiis 2004; Ruffo and Stoch 2005).

  • Crustacea, Copepoda, Harpacticoida) from Western Australia

Two new subterranean Parastenocarididae (Crustacea, Copepoda, Harpacticoida) from Western Australia T. Karanovic Western Australian Museum, Locked Bag 49, Welshpool DC, Western Australia 6986, Australia E-mail: [email protected] Abstract - Two new species of the genus Parastenocaris Kessler, 1913 are described from Australian subterranean waters, both based upon males and females. Parastenocaris eberhardi sp. novo has been found in two small caves in southwestern Western Australia. It belongs to the "minuta"-group of species, having five large spinules at base of the fourth leg endopod in male. The integumental window pattern of P. eberhardi is the same as for the first reported Australian representative (P. solitaria), which helps to establish its affinities too, since only females of the latter species were described. Parastenocaris eberhardi has a clear Eastern Gondwana connection, like many other Australian copepods of freshwater origins. Parastenocaris kimberleyensis sp. novo is described from a single water-monitoring bore in the Kimberley district, northeastern Western Australia. It belongs to the "brevipes"-group of species, for which a key to world species is given. The present state of systematics within the family Parastenocarididae is briefly discussed.

SUMMARY The epikarst crustacean fauna from four Sicilian caves (Conza, Entella, Molara, and Zubbia del Cavallo caves) and four caves in the Lessinian Massif in the Venetian Prealps (Covolo della Croce, Ponte di Veja, Roverè Mille, Buso della Rana caves) was recently investigated. The two groups of caves differ in their environmental conditions: the Sicilian caves are fossil except one which has an active branch; they are all fed by strongly intermittent and scarce rainfall peaking in the fall. The Lessinian caves are fed by more abundant rainfall, with two yearly peaks (May-June and October-November); two of them are active, one has a temporary stream, one is fossil. The crustacean fauna found in the epikarst drip of each of the studied caves is characterized by interesting endemic harpacticoid and cyclopoid copepods, and one bathynellacean syncarid, often collected in only one cave. Higher diversity of stygobiotic taxa was recorded for the Lessinian caves (9 species of copepods in the Lessinian, and 6 species of copepods and one bathynellacean in Sicily); most of the taxa collected in Sicily are endemic to one cave.

Analysis of about 2500 samples collected from the alluvial sediments of certain rivers and streams, besides some bores in the riparian zone, mainly in the coastal deltaic belt of the rivers Krishna and Godavari in Andhra Pradesh State during 2000–2012 yielded 41 copepod and bathynellacean species. Of these, 31 new species have been formally described during the ongoing studies whereas the remainder are previously known ones. An annotated checklist of all these taxa is presented, giving the type locality and other localities of occurrence, methods of sampling, chief references, and also some taxonomic and/or ecological remarks wherever necessary. The harpacticoid copepod family Parastenocarididae and the eumalacostracan order Bathynellacea are two significant, major groups of stygofauna that have been recorded for the first time from India. Both these groups and also some cyclopoid copepods have clear-cut Gondwanan lineages, representing the remnants of unique ancient fauna that require urgent attention from conservationists in order that the overall evolutionary history of the Indian biota is preserved. A note is also added on the devastating influence of the ongoing rampant sand mining activity on the hyporheic biodiversity.
