Gasteruptiidae Ashmead, 1900

Diagnosis.

Body length between 5.0-20.0 mm; female antenna 14-segmented, male 13-segmented, very rarely 14-segmented; eye relatively long, extending almost to mandible; mandibles short and not broadly overlapping when closed; maxillary palp 6-segmented, labial palp 4-segmented; propleuron neck-like, more or less as long as mesoscutum in front of tegulae; propodeum with or without longitudinal carina; fore wing with discal cell small or absent; trochantellus of hind leg distinctly differentiated, hind tibia (or metatibia) clavate; metasoma inserted very high on propodeum; ovipositor varies from not exposed (in Pseudofoenus) to more than twice as long as the body (Jennings and Austin 2002; Macedo 2009; 2011).

Gasteruptiidae includes two extant subfamilies, Hyptiogastrinae and Gasteruptiinae . Gasteruptiinae is distinguished from Hyptiogastrinae mainly by mandible short, prefemur present, female subgenital sternite notched or slit (Jennings and Austin 2002).

In China only the genus Gasteruption belonging to the subfamily Gasteruptiinae occurs.
