Family Praeaulacidae Rasnitsyn, 1972

Subfamily Praeaulacinae Rasnitsyn, 1972

Diagnosis. Antennae polymerous, rarely with 15 flagellomeres, usually more (14–17 in Cretocleistogastrinae). Forewing with pterostigma comparatively narrow (widely triangular or semicircular in Cretocleistogastrinae), M+Cu fork much closer to pterostigma than to wing base (nearly equidistant in Nevaniinae); 2–3r-m and 2m-cu always present (lost in Cretocleistogastrinae, only 2r-m lost in Anomopterellinae); 3r cell moderately wide (very wide and nearly triangular because of long and almost straight apical section of RS in Anomopterellinae); 2A absent (present in Nevaniinae). Hindwing with C absent (present in Nevaniinae), R strong, reaching apex of Rs and forming a distinct vein; cells rm and cua always closed (R lost beyond hamuli and cua cell lost in Cretocleistogastrinae). Ovipositor long, with sheaths more than half length of metasoma (shorter in Anomopterellinae).

Remarks. For the genera included in the subfamily and their distribution, see Zhang & Rasnitsyn (2008) and Rasnitsyn & Zhang (2010).
