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.
