Key to the species of Cacuminostreptus based on male gonopods

1. Apical metaplical process triangular ( Fig. 13a ) ............................................................................... triangulatus sp. n.

- Apical metaplical process not triangular ...................................................................................................................... 2

2. Oral fold of apical metaplical process longer and narrower than aboral fold; distally oral fold deflected laterally ( Fig. 11a ) ...................................................................................................................................................................... conatus

- Oral fold of apical metaplical process not longer than aboral fold; distally oral fold not deflected laterally ............. 3

3. Lateral margins of metaplicae strongly convex; apex of apical metaplical process concave and straight laterally, with small lateral and medial horns apically ( Figs 12a, 12b ) ................................................................... mazowensis sp. n.

- Lateral margins of metaplicae not strongly convex; apex of apical metaplical process flat and convex laterally, with- out lateral and medial horns apically ( Figs 14a, 14b ) ....................................................................... vumbaensis sp. n.
