Key to the identification of C. obsoletus species group from Indo-Burma

1. Eyes large, their diameter 1.1–1.2 times interocular distance, phallus slender, parallel-sided in apical half ( Fig. 20 ). ........................................................................................................................................................ C. bolavensis sp. n.

- Eyes smaller than their frontal interocular distance...................................................................................................... 2

2. Eye diameter at most 0.7 times frontal interocular distance......................................................................................... 4

- Eye diameter more than 0.7 times frontal interocular distance .................................................................................... 3

3. Phallus parallel-sided in most of its length, only slightly wider in apical third ( Fig. 24 ). The maximum eye diameter in the lateral view 0.78 times frontal interocular distance ................................................................. C. matsudai sp. n.

- Phallus is the widest in its apical two fifths of length, getting narrow to the apex ( Fig. 29 ). The maximum eye diam- eter in the lateral view 0.85 times frontal interocular distance ........................................................ C. kundratai sp. n.

- Phallus wider in middle ( Fig. 25 ) or apical part of its length ( Figs 23–24, 26–28 )...................................................... 5

5. Phallus wide in middle of apical part and gradually narrower towards middle and apex ( Figs 26, 27 ) ...................... 6

- Phallus almost parallel-sided in wider apical half ...................................................................................................... 7

6. Phallus 6.5 times longer than wide at the widest part ( Fig. 26 ) ....................................................... C. dembickyi sp. n.

- Phallus 8.0 times longer than wide at the widest part ( Fig. 27 ) ........................................................ C. hergovitsi sp. n.

7. The apical half of phallus slightly slenderer towards apex ( Fig. 23 ) .................................................... C. jendeki sp. n.

- The apical part or phallus parallel-sided ( Fig. 28 ) ........................................................................... C. yunnanus sp. n.
