Hetreulophidae new status

Hetreulophini Girault, 1915. Type genus: Hetreulophus Girault, 1915.

Diagnosis.

Antenna with 9 flagellomeres, including a 1-segmented clava. Clypeus without transverse subapical groove. Labrum flexible, hidden behind clypeus. Mandibles with 3 teeth. Subforaminal bridge with postgena separated by lower tentorial bridge except for the small postgenal bridge dorsal to the hypostoma. Mesoscutellum with short frenum, with axillular sulcus, and expanded, convex axillula (Fig. 23 ). Mesopleural area without an expanded acropleuron; mesepimeron extending over anterior margin of metapleuron (Fig. 23 ). Propodeum with spiracle small, oval, separated by more than its own length from anterior propodeal margin (Fig. 24 ). All legs with 5 tarsomeres; protibial spur stout and curved; basitarsal comb longitudinal.

Discussion.

Ceidae , another family with propodeal spiracle separated far from the anterior margin of the propodeum, differ in having 12 antennal flagellomeres and only 2 mandibular teeth. Macromesidae share this feature as well, but have at least 10 flagellomeres including multiple clavomeres, 4 mesotarsomeres in females, and the mesepimeron does not extend over the anterior margin of the metapleuron. Otherwise, families that resemble Hetreulophidae in habitus have more flagellomeres and multiple clavomeres.

Omphalodipara Girault new placement is transferred from Colotrechninae , Amerostenini ( Pteromalidae ) to Hetreulophidae based on next generation molecular data (Cruaud et al., submitted). Given the 9 antennal flagellomeres with a 1-segmented clava, strongly convex axillula, short frenum, and posteriorly displaced propodeal spiracle shared between Omphalodipara and other Hetreulophidae , it is reasonable to say that morphology agrees with this placement.
