Taxonomic key to males of Kinrentius

1 Pygofer, in lateral view, with apex acutely rounded, ventral margin with anteroventral ( AVP) and posteroventral ( PVP) processes ( Figs 9–10 , 18–19 ); aedeagus weakly constricted sub-basally between preatrium and shaft ( Figs 14 , 23 )................ 2

- Pygofer, in lateral view, with apex broadly rounded ( Fig. 10 in Wei, Dietrich & Webb 2010), ventral margin without processes; aedeagus strongly constricted sub-basally between preatrium and shaft ( Wei, Dietrich & Webb 2010: Figs 22–26 )........................................................................... K. constrictus Wei, Dietrich & Webb, 2010

2 Pygofer with posteroventral processes very short ( PVP in Fig. 18 ); aedeagus with paired apical processes, each subquadrate with apical margin slightly serrate ( Fig. 25 )........................................ Kinrentius peruvianus sp. nov.

- Pygofer with posteroventral processes well developed ( PVP in Figs 9, 10 ); aedeagus with paired apical processes, each acute with apical margin strongly serrate ( Fig. 16 )............................................................... 3

3 Pygofer with anteroventral ( AVP) and posteroventral ( PVP) processes multidentate, with several short teeth between processes ( Fig. 9 ); aedeagus median portion with well-developed dorsal projection forming a distinct process ( Fig. 14 ), apical paired processes, in lateral view, strongly expanded and with anterior margin broadly rounded ( Fig. 14 )..................................................................................................... Kinrentius catuaba sp. nov.

- Pygofer with anteroventral and posteroventral processes not multidentate, without teeth between processes; aedeagus median portion with dorsal projection small, tooth-like, and apical paired processes, in lateral view, moderately expanded and with anterior margin acute ( Wei, Dietrich & Webb 2010: Figs 13 , 20, 21 )........... K. bispinosus Wei, Dietrich & Webb, 2010 .
