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.
