Ectopoides brevicornis (Kriechbaumer, 1890)

This small genus belongs to the tribe of Platylabini . The antennae are rather short and uniquely shaped in the tribe (together with Apaeleticus spp. ): filiform for females and semi-bristle shaped for males. Furthermore, the thyridia are narrower than the interval between them and the gastrocoeli are very small and only feebly impressed ( TERESHKIN, 2009).

E. brevicornis has a predominantly black head and mesosoma. Only its tegulae, upper part of its mesopleuron and its scutellum are more or less white. The metasoma is red except for the first abdominal segment and the apical segments, which are black. The hind tibiae and femora are also red, but with a broad black band apically. The females have a white band on their antennae ( RASNITSYN & SIITAN, 1981).

First report of the species and the genus for the Netherlands; unreported Belgium.
