Gonotypus melanostoma (Thomson, 1887)

A small black species (more or less 4 to 6 mm) with glymmae which are sometimes hard to see on the first tergite. The ovipositor is very stout, about twice as long as the metasomal maximum depth ( TOWNES, 1970b). Its pterostigma is brownish, the tegulae are white ( SCHMIEDEKNECHT 1908). Our findings probably constitute the most southern observations so far. Among its hosts are rather rare Coleophora spp. ( Lepidoptera ) connected to Juncus spp. ( SHAW et al., 2016).

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