Family Paracortinidae Wang & Zhang, 1993

Emended diagnosis.

Middle-sized callipodidans with well-developed pleurotergal crests, poriferous ones prominent; male head either unmodified or with a prominent bulge. Pleurotergal setae apically pointed, usually in anterior position until PT4, on PT 5 some setae migrate posteriorly, and from PT6 all are in posterior position. Gonopods: parallel, diverging or converging. Sternum reduced or fused with coxae; coxae freely connected through a medial membranous lamina. Each gonopod with one or two prefemoroidal processes clavate and setose (pf1, pf2); one or two coxal lobes and a mesal coxal process varying in size; telopodite (T) long, unbranched in proximal parts, sometimes curved, twisted or forming a sharp angle at mid-length, distally complex with apical folds and lamellae and smaller projections, ending with solenomere (s) and parasolenomere (ps). Leg 2 in adult females reduced to two simple sclerites.

In most representatives of the family we examined, the chaetotaxy in the anterior pleurotergites is the same and follows this distribution (Table 1 ), except in the Vietnamese species Paracortina multisegmentata and P. kyrang . As already established by Wang and Zhang (1993), some paracortinids have a greater number of setae on each hemipleurite (6 or 7) from PT 6 onwards. However, the majority of the species show a 5+5 pattern.
