Key to species of Kuzicus  (for males only)

2. Tenth abdominal tergite with one or two pairs of apical lobes (Figs. 1 B – 1 H, 2 B – 2 J). 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. 3View FIGURE 3 B – 3 J)........................................................ 4

- Tenth abdominal tergite with two pairs of apical lobes (Figs. 1 A, 2 A, 6 C). Epiphallus without denticles and these appendiceslobules but with a pair of robust unarticulated projections directed anteriorly (backward from the apex) ( Figs. 3View FIGURE 3 A, 6 G)..... 3

3. Tenth abdominal tergite with median lobes with stout ventral teeth apically; with lateral lobes obtuse apically ( Figs. 6View FIGURE 6 C, 6 E) Cercus stout and short ( Figs. 6View FIGURE 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. 6View FIGURE 6 G).... K. pakthongchai Tan et al.  sp. n.

- Tenth abdominal tergite with median lobes without tooth apically; with lateral lobes tapering apically (Figs. 1 A, 2 A). Cercus long and slender ( Fig. 4View FIGURE 4 A). Epiphallus with a pair of tongue-shaped lateral processes pointing posteriorly at the apex; with posterior margin rounded ( Fig. 3View FIGURE 3 A)...................................................... K. uvarovi Gorochov, 1993 

4. Tenth abdominal tergite with two pairs of apical lobes (Figs. 1 G, 2 I)............... K. scorpioides Sänger & Helfert, 2006 

- Tenth abdominal tergite with one pair of apical lobes (Figs. 1 B – 1 H, except 1 G, 2 B – 2 J, except 2 I); if with two pairs, lateral lobes are small and truncated ( Figs. 8View FIGURE 8 C, 8 D)................................................................ 5

5. Tenth abdominal tergite with medial lobes modified or bifurcate at the apex (Figs. 1 B, 1 D, 1 H, 2 B, 2 D, 2 H, 2 J)........... 6

- Tenth abdominal tergite with medial lobes simple, usually forming a flattened disc at the apex (Figs. 1 C, 1 E, 1 F, 2 C, 2 E, 2 F, 2 G)................................................................................................. 9

6. Tenth abdominal tergite with medial lobes bifurcate at the apex (Figs. 1 H, 2 J). Epiphallus as shown in Fig. 3View FIGURE 3 J.................................................................................. K. suzukii (Matsumura & Shiraki, 1908) 

- Tenth abdominal tergite with medial lobes highly modified, forming structure (Figs. 1 B, 1 D, 2 B, 2 D, 2 H). Epiphallus not as above............................................................................................... 7

7. Tenth abdominal tergite with apex of medial lobes with minute teeth and warts (Figs. 1 B, 2 B, 8 C, 8 E). Cercus with basal process, apex acute (Figs. 1 B, 4 B, 4 C, 8 F). Epiphallus at apex with one large tooth and numerous minute denticles on each side ( Figs. 3View FIGURE 3 B, 8 E, 8 G)..................................................................................... 8

- Tenth abdominal tergite with apex of median lobes without minute teeth and warts (may have ventral spine-like process); with apex of medial lobes forming a hammer-head structure (in lateral view) (Figs. 1 D, 2 D). Cercus without basal process, apex with minute teeth ( Fig. 4View FIGURE 4 F). Epiphallus at apex with two pairs of relatively large dentiform processes ( Fig. 3View FIGURE 3 D)....................................................................................... K. compressus Han & Shi, 2014 

8. Tenth abdominal tergite with median lobes denticulated on the dorsal and posterior margins at the apex (Figs. 1 B, 2 B).......................................................................... K. aspercaudatus Sänger & Helfert, 2006 

- Tenth abdominal tergite with median lobes denticulated on the ventral margin at the apex only ( Figs. 8View FIGURE 8 C, 8 F)...................................................................................... K. multidenticulatus Tan et al.  sp. n.

9. Cercus bifurcate at the apex; with ventral process stout, dorsal process slender ( Figs. 4View FIGURE 4 D, 4 E). Epiphallus broader and with articulated ventral processes small ( Fig. 3View FIGURE 3 C)....................................... K. cervicercus (Tinkham, 1943) 

- Cercus not bifurcate at the apex ( Figs. 4View FIGURE 4 G – 4 K). Epiphallus more slender and/ or with articulated ventral processes longer ( Figs. 3View FIGURE 3 E – 3 H)........................................................................................ 10

10. Median lobes of tenth abdominal tergite appears distinctively bulbous at the distal end in lateral view (Fig. 2 G). Epiphallus with articulated ventral processes short and stout ( Fig. 3View FIGURE 3 G)................ K. megaterminatus Ingrisch & Shishodia, 1998
