Key to species of

1I
, 2K)..........................................................................................
K. koeppeli

2. Tenth abdominal tergite with one or two pairs of apical lobes (Figs. 1B–1H, 2B–2J). Epiphallus with small ventro-subapical inflation with small denticles and a pair of small semi-articulated, spine-like appendices or lobules directed more or less posteriorly (forward from the apex) or laterally (
Fig. 3
B–3J)........................................................ 4
- Tenth abdominal tergite with two pairs of apical lobes (Figs. 1A, 2A, 6C). Epiphallus without denticles and these appendiceslobules but with a pair of robust unarticulated projections directed anteriorly (backward from the apex) (
Figs. 3
A, 6G)..... 3
3. Tenth abdominal tergite with median lobes with stout ventral teeth apically; with lateral lobes obtuse apically (
Figs. 6
C, 6E) Cercus stout and short (
Figs. 6
G). Epiphallus with a pair of tongue-shaped lateral processes pointing anteriorly at the apex; with posterior margin producing into a plate in the middle (instead of rounded) (
Fig. 6
G)....
K. pakthongchai
Tan
et al.
sp. n.
- Tenth abdominal tergite with median lobes without tooth apically; with lateral lobes tapering apically (Figs. 1A, 2A). Cercus long and slender (
Fig. 4
A). Epiphallus with a pair of tongue-shaped lateral processes pointing posteriorly at the apex; with posterior margin rounded (
