A new mayfly species, Sparsorythus sivaramakrishnani sp. nov. from the stream of Pullian cholai, Thuraiyur, Namakkal district, Tamil Nadu, India is described based on male and female nymphs. Sparsorythus sivaramakrishnani sp. nov. differs from the closely related S. gracilis by the shape of the left prostheca, the number of bristle-like processes at base of left prostheca, the ratio and shape of right prostheca, the ratio of femur length: width, the size of the female nymph, the mesonotum overlapping in fifth abdominal segment of the female, and by the shape of hypopharyngeal lingua.

A New Species

We describe a new species of shieldtail (uropeltid) snake, Uropeltis rajendrani sp. nov., from the Kolli Hill complex of the southern Eastern Ghats in Tamil Nadu, India.  The new species belongs to the U. ceylanica group and is differentiated from related species in having 16–17:16–17:15–16 dorsal scale rows; 145–158 ventral scales; 8–11 pairs of subcaudals; dorsum uniform brown, anteriorly powdered with yellow mottling; venter brown, scales outlined with yellow.  This endemic species with a restricted range is known only from atop Kolli Hill complex, inhabiting higher elevation (> 900m) evergreen forests, where it is the only known member of this genus. Allopatric species, endemism, isolated massif, Uropeltis rajendrani sp. nov., Western Ghats.

A New Species

Hydrocotyle kollimalayensis, a new species is described and illustrated from Kolli hills of South Eastern Ghats, Tamil Nadu, India. The new species is morphologically closer to H. sibthorpioides, but differs from the latter by its filiform stem, glabrous peduncle, shorter petiole and narrower flowers. The most prominent features of the new species Hydrocotyle kollimalayensis are: stem filiform with silky setaceous hairs; leaves sparsely hirsute above and dense below, 5-lobed; flowers 6-12 per inflorescence with glabrous peduncle; and fruits ellipsoidal with 3 obscure ribs. A key to distinguish the new species from other Hydrocotyle species of Tamil Nadu, India is provided. We also inferred the relationship of H. kollimalayensis with allied species using molecular phylogenetic analyses based on nrDNA ITS sequence data.DOI: http://dx.doi.org/10.3329/bjpt.v21i2.21356Bangladesh J.

A New Species

We describe a new species of Asian gracile skink from the dry leeward slopes of the Nilgiri hills, Tamil Nadu state, India which forms a part of the eastern, rain shadow escarpment of the Western Ghats in peninsular India. The new species, Subdoluseps nilgiriensis sp. nov., is characterized by: slender, small-sized body (47–67 mm); sandy brown above, with each scale tipped with black; a thick black lateral band from snout to tail; a distinct white labial streak; dirty white venter, with throat having mild black striations; 28–29 midbody scale rows; 71–74 mid ventral scales; 66–69 paravertebral scales. The new species is described based on external morphological characters, genetic data and geographical isolation. Based on two mitochondrial DNA genes, we show that the new species shares a sister relationship with Subdoluseps pruthi (Sharma, 1977) which is found in parts of the Eastern Ghats in peninsular India. The discovery of this new population raises two novel scenarios. Firstly, it renders the genus Subdoluseps evolutionarily polyphyletic with respect to the Indian species included in this genus. Secondly, it falsifies the notion that S. pruthi group skinks are restricted to the Eastern Ghats. Our results further indicate that the dry zone of peninsular India has unrealized skink diversity that needs to be further explored.

A New Species

Impatiens megamalayana, a new species from Tamil Nadu, India is described and illustrated. This species is characterized by a ridged stem, ensiform and villous leaves, a wrinkled boat-shaped lower sepal with outwardly curved tip, ornamented seeds and strictly ovate pollen grains. This combination of characters makes determining the relationships of I. megamalayana difficult. The floral structure of I. megamalayana is closely allied to I. herbicola Hook.f. and I. inconspicua Benth. in Wall., the latter with three varieties, but it differs by several unique vegetative and floral features. Impatiens megamalayana is assessed as Critically Endangered in accordance with the IUCN guidelines. The habitat of the species is severely affected by landslides. As a result, effective strategies should be developed to protect I. megamalayana from exinction.

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.
