External morphology of the genital organs

(Figs 60 .7, 60.9, 60.11). The V is as long as the FO. The FDBC is longer than the SDBC+BC. The BC+SDBC is club-like in shape, with a more or less clear distinction between the SDBC and the BC. The D is much longer than the SDBC+BC and slightly thinner. The V is long but thin in diameter. The PC is ~ 2 × longer than the V. The P is wide in diameter and swollen. The transition between P and EP is clearly visible. The PR is long and robust. The E is slightly longer than the P but thinner in diameter.

Internal morphology of the genital organs

(Figs 60 .8, 60.10, 60.12). The V presents many smooth longitudinal pleats that stop immediately before entering the A. The P shows five to seven longitudinal to irregularly fringed pleats that continue as far as the A where they become smooth. These penial pleats are irregular and randomly split and merge again one into the other and irregularly split or merge one into another. The pseudopapilla is smooth, short to moderately long. It originates from the ER which is connected to the ELP by means of three or four smooth longitudinal pleats. The two ELP are slightly fringed and fade before entering the VD. The epiphallar formula is PP(ER)+ELP.
