Colasposoma aeneoviolaceum is a species of leaf beetle of the Democratic Republic of the Congo. It was first described by the Belgian entomologist Burgeon 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.
