description: Identification key to the species of Kamabrachys gen. nov.
The following key uses the characters of the male terminalia. Females should not be identified unless a male from the same collecting event is available to confirm the identification.
1. Posterior margin of the lateroventral lobe of the pygofer (lvl) rounded in lateral view (Figs 7A, 12A); in ventral view, also rounded (Figs 7C, 12C) ................................................................................... 2

– Crest of furcate processes of periandrium (cfp) extending only along distal portion, never merging basally (Figs 9D–E, 14D–E) ............................................................................................................. 3
3. Apicodorsal process (adp) of aedeagus rather weakly sinuate, elongate and narrow, surpassing apicoventral process (avp) (Fig. 64A, C) .................... K. signata (Distant, 1892) gen. et comb. nov.
– Apicodorsal process (adp) of aedeagus strongly sinuate, rather wide and stocky, shorter than apicoventral process (avp) (Figs 9A, C, 14A, C, 38A, C, 55A, C) .................................................. 4
4. Posterior margin of the lateroventral lobe of the pygofer obliquely straight in middle portion in lateral view (Fig. 7A); ventral processes of gonostyli elongate, gonostyli 1.17 times as wide as long in ventral view (Fig. 7C) ....................................................................... K. andersoni gen. et sp. nov.
– Posterior margin of the lateroventral lobe of the pygofer rounded in lateral view (Figs 12A, 36A, 53A); ventral processes of gonostyli elongate, gonostyli at least 1.25 times as wide as long in ventral view (Figs 12C, 36C, 53C) ............................................................................................................... 5
5. Posterior margin of laterodorsal process of gonostylus (ldg) in lateral view, emarginate, leaving a widely open angle between laterodorsal process and ventral process (vp) of gonostylus (Fig. 36A) ................................................................................................................... K. fasciata gen. et sp. nov.
– Posterior margin of laterodorsal process of gonostylus (ldg) in lateral view, not emarginate, forming a narrow angle between laterodorsal process and ventral process (vp) of gonostylus (Figs 12A, 53A) .................................................................................................................................................. 6
6. Crest of median furcate process of periandrium (cfp) in lateral view, wider in distal portion (Fig. 14E); apicodorsal process of aedeagus (adp) in dorsal view, wider than apicoventral process of aedeagus (avp), stocky and obliquely truncate apically (Fig. 14A) ....................... K. brennani gen. et sp. nov.
– Crest of median furcate process of periandrium (cfp) in lateral view, wider in basal portion (Fig. 55E); apicodorsal process of aedeagus (adp) in dorsal view, about as wide as apicoventral process of aedeagus (avp), tapering apically (Fig. 55A) .................................................
