Description
An extremely sexually dimorphic species, a characteristic of most Chalcidoptera spp., with bright reddish brown males and mainly yellow females. There is some variability in the extent of yellow spotting on the males which have longer abdomens. The males have long fawn anal hair scales. Schulze (2000) taxon #506. C. pyrrhocosma Meyrick is said to be syn. (Shaffer et al. 1996) but there are similar specimens with slightly different FW apical patterning. So we illustrate those separately as C. pyrrhocosma? The association of male and female in many Chalcidoptera spp. needs re-confirmation. See Chalcidoptera pryeri Hampson, 1898. A morphotype from the Molluccas, resembling a male of this sp. is larger with a different wing shape and is probably not conspecific.
