A New Species

Sparsorythus srokai sp. nov. is described from the Veerapandi River, Theni district, Tamil Nadu, India based on nymphs of both sexes. The nymphs of Sparsorythus srokai sp. nov. can be distinguished by the following combination of characters: i) presence of lateral setae in each segment of caudal filaments, ii) dorsal surface of labrum entirely covered with scattered ribbon-like bristles, iii) posterior margin of mesonotum reaching abdominal segment III in both sexes, and iv) left prostheca with several pointed teeth apically. The new species is compared with other Indian species: S. gracilis Sroka & Soldán, 2008, S. sivaramakrishnani Sivaruban, Srinivasan, Barathy, Rosi & Isack, 2021 and S. nanjangudensis Muthukatturaja & Balasubramanian, 2021. The distributional map and key to the genus Sparsorythus in Southern India are also given.

A New Species

A new species of the gekkonid genus Cnemaspis is described based on a series of nine specimens from near Sankari in Salem district, Tamil Nadu state, southern India. The new species is diagnosable by the following suite of characters: a small-sized Cnemaspis (adult snout to vent length less than 33 mm); heterogeneous dorsal pholidosis consisting of weakly keeled granular scales intermixed with large strongly keeled, conical tubercles, 9–11 rows of dorsal tubercles, 12–17 tubercles in paravertebral rows; spine-like scales absent on flank, 17–20 lamellae under digit IV of pes. Males with 4–6 femoral pores on each thigh, separated on either side by eight poreless scales from four precloacal pores; precloacal pores separated medially by a single poreless scale; two single dorsal ocelli on occiput and between forelimb insertions, two pairs of ocelli on either side just anterior and posterior to forelimb insertions. Cnemaspis agarwali sp. nov. is the fifth endemic species of Cnemaspis from peninsular India outside the Western Ghats and highlights the rich and unique diversity of this understudied region.

A New Species

A new species belonging to the subgenus Isonychia, of the genus Isonychia Eaton, 1871, is described based on larvae and imagoes collected from Moyar River, Nilgiri District, Tamil Nadu, India. The imagoes of I. moyarensis n. sp. can be distinguished from other described Oriental species of Isonychia (Isonychia) by the combination of characters: (i) forewing with rusty brown maculae in the costal, subcostal, and median areas; (ii) femur and tibia brown, fore leg pale, apices of tarsal segments brownish; (iii) males with distal angles of penes rounded, without serrations; (iv) second segment of gonostylus uniformly convex; and (v) sterna of tenth abdominal segment in female deeply cleft. Isonychia (Isonychia) moyarensis n. sp. can be distinguished in the larval stage from other known Oriental species by the following combination of characters: (i) abdominal terga II–IX with median dark brown maculae progressively larger with dark brown slanting streaks in lateral margins; (ii) trachea of abdominal gills I–VII unbranched; (iii) posterolateral projections on abdominal segments I–VII blunt and progressively longer than those of segments VIII–IX, sharp and distinct; and (iv) abdominal terga X pale yellow in anterior ⅓, and dark brown in the posterior ⅔. A key to the known larvae of Oriental species of Isonychia is also provided.

Klimakodesmus Carl, 1932 is briefly redescribed, rediagnosed, and shown to be an oligotypic genus endemic to southern India and distinct from the particularly similar genus Pyrgodesmus Pocock, 1892, monobasic and endemic to Sri Lanka, by several important features of peripheral and, especially, gonopodal structure. A new species, Klimakodesmus bilobocaudatus sp. nov., is described from Kerala state, India, differing from the sole accepted, and type species K. gravelyi Carl, 1932, from Tamil Nadu state, primarily by the laterally trilobate paraterga, the caudally more deeply bilobate mid-dorsal keel on ring 19, and certain minor details of the gonopodal structure.
