Diomus is a genus of lady beetles that belongs to the family Coccinellidae. It can be found worldwide.[2][3][4]

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.[5]

Distribution

Members of this genus can be found worldwide with many species occurring in tropical and subtropical regions including adjacent islands.[5] 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.[6][7][4]

Taxonomy

This genus was originally described by Étienne Mulsant, an 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.[8] 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.[4]

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.[9] A list of species belonging to this genus can be found below:[2][10][11][3]
