Diomus is a genus of lady beetles that belongs to the family Coccinellidae. It can be found worldwide.

It can grow to a length of 1.2-3.5 mm. Its body is a elongated oval that is weakly convex. The coloration of their body and elytra is variable.

Distribution

Members of this genus can be found worldwide with many species occurring in tropical and subtropical regions including adjacent islands. They are mainly found in neotropical regions with more than 260 species described. The Australian region has 77 species with an estimated 140. Both the afrotropical and palaeartic regions contains 7 species and the oriental region contains 4 species.

Taxonomy

This genus was originally described by Étienne Mulsant, a French entomologist and ornithologist, in 1850 as a subgenus of Scymnus. It was than elevated to its own genus in 1895 by Weise. However its status as its own genus within the tribe Scymnini or a subgenus of Scymnus was controversial. (Chapin, 1933) considered it its own genus immediately distinguishing it from Decadiomus. Some thought that it was a subgenus of Nephus. In 1999, Gordon suggested that this genus was a allogenic genus from Scymnini and proposed the tribe Diomini.

Species

This genus is probably one of the largest genera in the family Coccinellidae. This genus currently contains more than 400 described species worldwide with many species possibly being undescribed. A list of species belonging to this genus can be found below:
