A new phreatic species of genus Parastenocaris Kessler (Copepoda: Harpacticoida: Parastenocarididae) from southeastern India, with a key to species of Indian subcontinent

Author[s]: Y. RANGA REDDY

Abstract: 

Parastenocaris tirupatiensis sp. nov. is described from southeastern India. It has a unique combination of characters in the male (the female unknown): leg 4 with five unequal, imbricate petaloid spinules at base of carpel-like hyaline endopod; leg 5 primitively large, with short spinous apical process, and unusually long, sturdy spinules on inner margin; caudal rami about 4 × width, with lateral group of setae and dorsal seta located distally and opposite each other; antennule “coiled type”; leg 2 endopod short, spatulate, with claw-like apical seta; leg 1 with inner armature element on basis, and endopod longer than exopod and with inner spinules; and leg 3 with rudimentary endopodal segment, apophysis shorter than thumb, and exopod with one row of spinules. This new phreatic species has some affinity with the West African Monodicaris species. A key to all the 16 parastenocaridid species known from the Indian subcontinent is also provided.

Abstract: 

A new Teleasinae Dvivarnus punctatus Rajmohana & Veenakumari gen. et. sp. nov. (Platygastridae: Hymenoptera), is described from South India. The new genus is apparently confined to the Deccan plateau, Southern India. Bioecological notes and a distribution map of the new genus are appended. Affinities of Dvivarnus with other Indian genera of Teleasinae are discussed. A dichotmous key to distinguish the genera of Indian Teleasinae is also provided.
