Distribution.

External morphology of the genital organs

(Fig. 54.1). The V is shorter than the FO. The FDBC is as long as the SDBC+BC. The BC+SDBC is slim, club-like in shape, with a clear distinction between the SDBC and the BC. The D is much longer than the SDBC+BC and thinner. The V is short and thin in diameter. The PC is ~ 2 × longer than the V. The P is cylindrical and slightly swollen along its proximal part. The transition between P and EP is clearly visible. The PR is long and robust. The E is as long as the P but much thinner in diameter.

Internal morphology of the genital organs

(Figs 54.2-54.6). The V presents irregular smooth pleats. The A has a fleshy, mushroom-like fold. The P shows many irregular smooth to fringed pleats. The hemipapilla is short, smooth to moderately folded. The outlet of the hemipapilla is slit-like. The E shows two moderately fringed ELP. They proximally fade before the VD.
