Phygadeuon dromicus (Gravenhorst, 1815)

Phygadeuon spp. are very common but need to be revised. At this stage only a limited group of well-defined species can be identified with absolute certainty. One of those groups consists of species with brachypterous females.

P. dromicus belongs to this group. Its fore wing is very short, measuring at most half of the hind tibia and it does not reach the scutellum. The third antennal segment measures more or less twice its width. Its colouration is also distinct. The antennae are often tricoloured (orangewhite-black). The mesosoma and metasoma are predominantly black except for the second and third tergite, which are reddish with black marks ( HORSTMANN, 1993). It is a known parasitoid of the coleopteran Oulema spp. ( Coleoptera : Chrysomelidae ) ( MICZULSKI, 1988).

First report for the Netherlands; unreported in Belgium.
