External morphology of the genital organs

(Fig. 51.1). The V is slightly longer than the FO. The FDBC is as long as the SDBC+BC. The BC+SDBC is cylindrical in shape without clear distinction between the SDBC and the BC. The D is longer than the SDBC+BC and thinner. The V is short and wide in diameter. The PC is ~ 3 × longer than the V. The P is cylindrical. The transition between P and EP is not clearly visible. The PR is short and thin. The E is slightly shorter than the P and thinner in diameter.

Internal morphology of the genital organs

(Figs 51.2-51.3). The A and the V are smooth or with weak irregular convolute pleats. The P presents irregular and wide longitudinal pleats. The hemipapilla is smooth and very short. The outlet of the hemipapilla is roundish. The E shows two moderately fringed ELP. They proximally fade before the VD.
