Type species: nivimacula Felder (= auratus Cramer), Sri Lanka.

• Chrysocaleopsis van Eecke (type species sarah Snellen, Sumatra = ada Butler)

• Pteroceropsis Swinhoe (type species unipuncta Swinhoe, Borneo).

This genus consists of a diverse array of rather robust mimics of bees and wasps that are generally black, with metallic bands and patches on the body and wings; the wings may also have transparent patches. The antennae are strongly plumose, and this effect can be intensified over the apical section to give a clubbed appearance. The description of the male genitalia in the previous section refers to this, the type genus, rather than the next. Dense scale tufts from the patagia conceal the extensive chaetosemata (Yen et al., 2005).

Semper (1896-1902) described and illustrated the larva of C. semperi Druce (Philippines), possibly the closest relative of C. ada Butler, the larva of which is very similar as described below. The larva is onisciform (woodlouse-like), brownish-black with the dorsal surface broadly orange-yellow except for segments A1-3 which are completely black, restricting the yellow to a thoracic patch and one over A4-7. There are lateral rod-like processes on all segments, brown on A1-3 but yellow with a dark tip elsewhere. Those on the thorax forwards and on A4-6 are longer than the rest, and those on A7 and A8 shorter.

Pupation is on a leaf or stem under a shallow, ovate dome of light grey silk.

The host plant recorded was Memecylon (Melastomataceae).
