Lathrostizus macrostoma (Thomson, 1887) View in CoL

Lathrostizus spp. are relatively hard to recognise and require careful keying and comparison with other campoplegine genera. There is the presence of an areolet and glymmae; and the hind wing with the distal abscissa of CU stopping short of the nervellus. Their clypeus is rather wide and their ovipositor is two to three times as long as the metasomal maximum depth, very strongly upcurved. Finally, the lower tooth of the mandible is not longer than the upper tooth ( TOWNES, 1970b).

Lathrostizus macrostoma View in CoL has relatively short ovipositor sheaths, measuring 1.3–1.6× as long as the first tergite. Its clypeus is black, the postpectal ridge is not remarkable. Our specimens had approximately 26 flagellomeres ( HORSTMANN, 2004). Tergites 2–4 are red brown, the other tergites are black. All our findings were coastal suggesting there are unknown hosts, although some of the known ones are common everywhere (see YU et al., 2012).

First report for Belgium and the Netherlands.
