Generic diagnosis

Females are characterized by the following characters ( Gibson 1995, 2005): body usually dark with various metallic lusters, but sometimes yellow to brown; head with ventral margin of torulus lower than lower orbit, scrobal depression deep or not but dorsally delimiting linear or only very narrow region along upper inner orbit; antenna with scape sometimes slender though often variably compressed; clypeus flat; mandible tridentate; pronotum usually subtriangular and divided medially; mesoscutum usually flat with anterior and lateral parts slightly raised, posterior part slightly concave; mesopectus with setae, acropleuron usually bare; fore wing usually hyaline at base, infuscate beyond base of parastigma, and sometimes with one or more lighter colored band or spots behind marginal vein; mesotibia with oblique apical groove and with dark apical pegs in a patch; gaster elongate, base of gaster usually without white region unlike species of Anastatus ; syntergum apically reflexed into fingernail like flange.

Key to females of Zaischnopsis from China
