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. |
