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 cryptic species of the genus Fejervarya is described from the Chittagong district of Bangladesh. Fejervarya asmati sp. nov. is compared with its morphologically similar and geographically proximate congeners. The species can be readily diagnosed by having the following combination of characters: SVL 29.1– 33.4 mm; butterfly shaped vocal marking present in male; forearm length 70% of hand length; relative length of fingers, shortest to longest: 2 < 4 < 1< 3; nostril much closer to snout tip than eye, nostril–snout length 57% of distance from front of eyes to nostril; nostril–snout length 0.67% of internarial distance; MBE 18% of HL.

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 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. Additionally, males possess paired vocal sacs. The new species is compared with known species of the genus Polypedates.

Agaricus duplocingulatoides (Agaricaceae, Agaricales, Basidiomycota) is proposed here as new to science based on collections made from West Bengal, Eastern India. The morphological features together with molecular data confirms its placement in Agaricus sect. Brunneopicti within Agaricus subg. Pseudochitonia. A comprehensive description, illustrations and comparison with morphologically and phylogenetically related taxa are provided.

Tritodynamia bengalensis n. sp. is described on the basis of a male specimen dredged from the shallow coastal waters of West Bengal state, India. The new species is morphologically similar to T. bidentata Yang & Tang, 2005 and T. serratipes Anker & Ng, 2014, but can be distinguished by the carapace shape, dentition of the pollex, relative length of the dactylus of the third maxilliped, proportions of the propodus of the third pereopod, and structure of the male left gonopod. This is the first record of the genus Tritodynamia from India.

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 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.

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 of Trogia (Marasmiaceae, Basidiomycota) is described from West Bengal, India. Analysis of the molecular sequence (nuclear ribosomal internal transcribed spacer region) data suggests that T. benghalesis is phylogenetically distinct from its closely related species. Comprehensive description based on macro- and microscopic characters, photographs and comparisons with morphologically similar and phylogenetically related species are provided.
