( Figures 10–13 )

Material

Holotype: male, Madagascar, Fianarantosa , 7 km W. Ranomafana, 20.83 ° S, 44.7 ° E, Malaise pans, 22–31 October 1988, W. E. Steiner ( LACM Ent. 095334—26-60).

Etymology

The name means careful or wary and refers to the fact that unless one is careful one may confuse this species with C. steineri .

Male

A generally brown species but mostly not dark. Antennae and palps light brown, the latter with numerous hairs but apical one only a little differentiated. All femora and tibiae light brown, but hind femur with a darker ventral band in basal half. Wing 1.2–1.3 mm long. Costal index about 0.6. Membrane tinged brown. Hypopygium brown and as Figures 10– 13 ; with the most anterior bristle on left side of epandrium strongly differentiated as a spine and right gonopod with a long and a short robust bristle.
