Rybocyclops dussarti Ranga Reddy & Defaye, 2008

( Fig. 23 )

Synonymy. Rybocylops dussarti Ranga Reddy & Defaye, 2008: 40–50, Figs. 1–3 .

Material examined. Two female topotypes collected from the type locality.

Remark. A close scrutiny of the topotypes of R. dussarti shows that the original figures and description of the antennule and antenna ( Figs. 23 a, b), especially of the former, are incomplete in certain respects. Hence fresh drawings are provided herein for both these appendages. Importantly, the female antennule has the modified conical seta on segment 5, an aesthetasc on segment 8 as well as segment 11, and plumosity on certain setae, but these details are missing in the original account. Otherwise, the topotypes examined perfectly agree with the original account.
