KEY TO GENERA OF CHEIROCHELINI

1. Abdominal and thoracic venter with thick erect hair pile, especially evident when viewed laterally; anterolateral angles of prothoracic venter curved inward to form cup-like depressions adjacent to eyes; ventral margin of anteclypeus with band of dense, short setae ................................................. Cheirochela

– Abdominal and thoracic venter lacking erect hair pile, bearing instead a covering of very fine, short, closely appressed hairs barely evident in lateral aspect; anterolateral angles of prothoracic venter not curving to form cup-like depressions; ventral margin of anteclypeus lacking fringe of setae ......... 2

2. Posterolateral abdominal angles produced, each ending in two sharp spinose projections ( Fig. 18 ); form broad, rounded; Indochina ............................................................... Gestroiella

– Posterolateral abdominal angles not produced, slightly notched and bidentate but not produced into bispinose projections; form elongate oval ( Fig. 1 ); Borneo ........................... Coptocatus
