Colasposoma aeneoviolaceum explained

Colasposoma aeneoviolaceum is a species of leaf beetle of the Democratic Republic of the Congo.^[1] It was first described by the Belgian entomologist in 1941.

Description

Adults measure between 7 and 10 mm in length. They have a shiny bronze-coloured dorsum, while the edges of the pronotum, the underparts and the feet are violet in colour. However, one specimen from Moliro was found with a blue underside. The species generally resembles Colasposoma overlaeti.

Subspecies

There are two subspecies of C. aeneoviolaceum:

• Colasposoma aeneoviolaceum aeneoviolaceum Burgeon, 1941: the nominotypical subspecies
• Colasposoma aeneoviolaceum elisabethae Burgeon, 1941: Compared to the nominal form, the adults differ in their bronze colouring, have a cupreous or tanned underside, and have less abundant elytral punctuation. The subspecies was described from Élisabethville (now Lubumbashi), in the south of Katanga.
