A New Species

Abstract The hymenosomatid crab Neorhynchoplax devroyi sp. nov. is described here from West Bengal in eastern India. The species is most similar to N. demeloi Kemp, 1917, described from Cochin in western India, but can easily be distinguished by its proportionately longer and more slender ambulatory legs, truncate cutting teeth on the chelipeds, relatively broader first pleonal somite and the distal part of the male first gonopod being stout and short. Ten species of Neorhynchoplax Holthuis, 1968, are now known from Indian waters.

A New Species

The genus Platylestes Selys, 1862 is known from India, by only one species, P. platystylus from eastern India, West Bengal, and recently from Kerala.  Here, we describe a new species Platylestes kirani from the coastal tracts of the northern part of Kerala, southern India.  The new species differs from all other known species of the genus by its unique coloration, distinct marking on synthorax, and the shape of anal appendages.

A New Species

A new species of green frog of the genus Euphlyctis Fitzinger, 1843 is described from West Bengal, a state of eastern India. A robust frog, SVL of male 86mm and that of female 132mm. The species is diagnosed by the presence of following characters: green dorsum and female with a greenish white mid-dorsal line, tibiotarsal articulation reaches eye, male with two vocal sac openings at the junction of jaw, female is larger than male though body parameters is proportionately longer in male, nostril snout length 3.45% of SVL, nostril much closer to snout tip than eye, units of hind limb i. e. thigh, shank and foot are almost equal in length, relative length of finger: II < IV < I < III. The new species is compared with existing eight species of the genus Euphlyctis.

A new species of frog belonging to the genus Polypedates Tschudi is described from the state of West Bengal, Eastern India. A mid-sized frog, SVL ranges from 47.9–53.6 mm in males and 72.0 mm in the single female. The species is diagnosable in showing the following suite of characters: digits lack webbing, inner and outer metacarpal tubercles present; no dermal fold on forearm; toes webbed, webbing formula I1–1 II0.5–2III1–2IV2–0.5V; an inner metatarsal tubercle present; tibio-tarsal articulation reaches between eye and nostril; and skin on forehead co-ossified to cranium.

A New Species

The tribe Polydrepanini is rediagnosed through an elongate, mostly slender, sometimes twisted/helicoid gonofemorite and a more or less thin, mostly flagelliform, suberect, apical or subapical solenomere often forming a conspicuous loop/curve near the base. The tribe presently encompasses seven genera, all redefined, illustrated and keyed: Dasypharkis Attems, 1936, stat. revalid., Delarthrum Attems, 1936, Grammorhabdus Carl, 1932, stat. revalid., Pocockina Jeekel, 1965, Polydrepanum Carl, 1932 (= Gyrodrepanum Carl, 1932 and Hindomorpha Golovatch, 1984, both syn. nov.), Telodrepanum Carl, 1932, and Xiphidiogonus Carl, 1932. The genus Polydrepanum is shown to currently comprise only four described species, all also redefined, depicted and keyed: Polydrepanum tamilum Carl, 1932 (the type species), P. horridum Golovatch, 1984, P. granuliferum (Attems, 1936), comb. nov. ex Hindomorpha, and P. lamprum (Chamberlin, 1920), comb. nov. ex Gyrodrepanum. Grammorhabdus fissus (Sankaran & Sebastian, 2018) is formally transferred from Polydrepanum, comb. nov. Because Polydrepanum implicatum Carl, 1941 shows a strongly shortened gonopodal femorite, coupled with a distal and flagelliform solenomere, this species is considered as not only somewhat intermediate between the tribes Alogolykini and Polydrepanini as redefined here, but it is formally assigned to Alogolykini as the type species of Carlogonopus gen. nov. (masculine), with C. implicatus (Carl, 1941), comb. nov. ex Polydrepanum, as well as a comb. nov. ex Telodrepanum. A somewhat similar situation concerns Manikidesmus suriensis Bhakat, 2021, a still invalid genus and species from West Bengal, eastern India that likewise shows a clearly shortened gonofemorite. However, this being even more important, Manikidesmus suriensis is a “nomen nudum” not available yet for zoological nomenclature. The large and mainly Himalayan genus Delarthrum is briefly reassessed, mainly in connection with a new species, D. anomalans sp. nov., described from Kerala, southern India and placed in a species-group of its own. Some general considerations concerning the diversity and distribution of the subfamily Alogolykinae are presented.

A new snake eel (Anguilliformes: Ophichthidae: Ophichthinae) species, Ophichthus kailashchandrai sp. nov., is described from three specimens, collected from the Shankarpur fishing harbour located on the northern part of the Bay of Bengal, West Bengal, India. Ophichthus kailashchandrai sp. nov. is distinguished from its congeners by having its dorsal-fin origin at the posterior third of the pectoral fin, preanal length 2.6–2.8 in TL, uniserial maxillary and mandibular teeth and vertebral count (predorsal vertebrae 14–15, preanal vertebrae 54–55, and total vertebrae 180–182).

The identity of the majid species of Paramaya De Haan, 1837, in the Indian Ocean is clarified with the collection of fresh specimens from the Bay of Bengal. Previously identified as P.spinigera (De Haan, 1837) which is known only from Japan, Taiwan, and Korea, the material from eastern India is here referred to a new species, P.mulli sp. n. The new species can easily be distinguished from all congeners by its relatively shorter pseudorostral and carapace spines, more swollen branchial regions, distinctly granulated male thoracic sternum, and the G1 is not prominently curved with the dorsal projection on the sub distal part short and the tip rounded.

A new species of the genus Microhyla, Microhyla bengalensis sp. nov., described from West Bengal state, India. The new species is distinguished from its congeners by a combination of the following morphological characters: 1) Small in size (SVL= 16.2 mm. in male); 2) truncated snout in dorsal view; 3) head wider than long (HW: HL= 1.36); 4) canthus rostralis and tympanum are indistinct; 5) nostril placed on the dorsal side of the snout; 6) tibiotarsal articulation not reaching the eye; 7) fingers and toes without disc; 8) toe webbing basal; 9) thigh and foot length are equal and smaller than shank; 10) skin tuberculated on dorsum; 11) 'teddy bear' dark brown mark on dorsum; 12) an inverted 'V'-shaped dark brown mark above the vent. A comparative morphological data of all the 14 Indian species of Microhyla is also provided.

We describe a new species of the Rhacophorus genus, which differs from all species known in Asia by the combination of characters. It strongly differs also from small and middle-sized species of Rhacophorus sensu lato: Rhacophorus calcaneus Smith, 1924, Leptomantis cyanopunctatus (Manthey et Steiof, 1998), Rhacophorus hoabinhensis Nguyen, Pham, Nguyen, Ninh et Ziegler, 2017, Rhacophorus hoanglienensis Orlov, Lathrop, Murphy et Ho, 2001, Zhangixalus jarujini (Matsui et Panha, 2006), Rhacophorus laoshan Mo, Jiang, Xie et Ohler, 2008, Rhacophorus pardalis Günther, 1858, Rhacophorus rhodopus Liu et Hu, 1960, Rhacophorus robertingeri Orlov, Poyarkov, Vassilieva, Ananjeva, Nguyen, Sang, and Geissler, 2012, Leptomantis robinsonii (Boulenger, 1903), Rhacophorus spelaeus Orlov, Gnophanxay, Phimminith, and Phomphoumy, 2010, Rhacophorus translineatus Wu, 1977, Rhacophorus turpes Smith, 1940, Rhacophorus vampyrus Rowley, Le, Thi, Stuart et Hoang, 2010, Rhacophorus viridimaculatus Ostroshabov, Orlov et Nguyen, 2013 by having brown color with two green dorsolateral stripes starting at the groin level and connecting through the distal part of eyelid with green triangle on the head, slender body and head, lower ratio HW/HL 0.86, lower HW/SVL 0.28 and lower ratio HL/SVL 0.32.
