Lochetica westoni (Bridgman, 1880)

An outstanding species within the subfamily. The lower edge of the mandibles is rounded and the hairs on the outer face of the mandibles are dense and short. In the fore wing, wing vein 2m-cu only has one bulla and the areolet is relatively large and closed. Finally, the ovipositor is relatively long for a species in this subfamily, only slightly less than the total fore wing length. Our specimens have a more or less black mesosoma and red metasoma (except for the apical tergites and base of the first tergite). Its basal flagellomeres and its legs are orange. It is a known parasitoid of the rather uncommon crabronid wasp Passaloecus insignis (Vander Linden, 1829) ( Apocrita : Crabronidae ) (see for example KREISCH, 2000).

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

Medophron recurvus (Thomson, 1884)

This genus belongs to the subtribe Endaseina . The fore wing vein 2m-cu is weakly inclivous or vertical and the hind edge of the mesoscutum has a transverse break. Their prescutellar transverse groove does not have a median longitudinal ridge. Their area superomedia is much wider than long ( TOWNES, 1970a).

M. recurvus has its areolet closed and its flagellum has a whitish band. Its metasoma is shiny and entirely red, except for the first tergite which is black, at least basally. Its ovipositor sheaths are about half as long as the metasoma ( JONAITIS, 1981).
