The genus Anisobas belongs to the small tribe Listrodromini . Their genal carina is meeting the hypostomal carina at the base of the mandible and the transverse furrow of the pronotum has a large shining central keel. Anisobas spp. have mandibles with a normal hind margin (not raised). The spiracles of the propodeum are double the size in length than breadth, the clypeus is conspicuously flat. There are short dentiparal spines on the propodeum ( PERKINS, 1959; HORSTMANN, 2007).

Anisobas rebellis does not have an elevated scutellum. Its temples and mandibles are normal, but its head, viewed in front, is triangular (BERTHOUMIEU, 1895; RASNITSYN & SIITAN, 1981). The hind femora are reddish (exceptionally black) and relatively slender (3.6–4.3× as long as wide). The hind tibiae and tarsi often are completely black. The antennae have 29–34 flagellomeres. Its hosts are butterflies from the genus Lycaena ( Lycaenidae ) ( HORSTMANN, 2007). First report for Belgium and the Netherlands.
