Aneuclis brevicauda (Thomson, 1889)

Aneuclis spp. belongs to the group clustered around the genus Diaparsis . Both genera do not have glymmae on the first tergite (or it is isolated) and the propodeum has one basal keel. Typical for Aneuclis spp. , however, is the brachial cell of the fore wing which is widely open at apex and the posterior part of the postnervulus which is absent. The fore wing vein 2m-cu is present ( KHALAIM & YURTCAN, 2011).

A. brevicauda is a small species. Our specimen measured 2.5 mm and had 14 flagellomeres. Its ovipositor is relatively short, about as long as the first tergite (which has striations dorsolaterally). Its mesosoma and metasoma are black ( KHALAIM, 2004a). It has been reported as a parasitoid of the common coleopteran Phyllotreta nemorum (Linnaeus, 1758) ( Coleoptera : Chrysomelidae ) (HORSTMANN, 1980b).
