Etymology.

From Greek prefix para and weyersi, a patronym from Weyers, referring to similarities with Ptocasius weyersi .

Diagnosis.

Similar to Ptocasius weyersi (see Żabka 1985: figs 530-532), but the tegulum has one small bump (Fig. 38D) and the RTA is straight (Fig. 38B) vs. bent backward in Ptocasius weyersi . The female resembles Ptocasius weyersi , but differs by having two epigynal hoods (Fig. 39A) vs. one. Compared to Ptocasius songi Logunov, 1995, the hoods are located medially (Fig. 39A) vs. laterally and the receptacles are elongate (Fig. 39B) vs. spherical.
