Diparidae new status

Diparinae (=Diparides, not Latin) Thomson, 1876. Type genus: Dipara Walker, 1833.

Diagnosis.

Antenna with 12 flagellomeres, including a small 4th clavomere. Eyes not ventrally divergent. Labrum hidden behind clypeus, flexible, subrectangular, with marginal setae in a row. Mandibles with 3 or 4 teeth. Subforaminal bridge with postgenal bridge occurring dorsal to the hypostoma (Fig. 15 ). Mesoscutellum with frenum indicated at least laterally, and with axillular sulcus. Mesopleural area without an expanded acropleuron; mesepimeron not extending over anterior margin of metapleuron (except in Diparisca Hedqvist). All legs with 5 tarsomeres; protibial spur stout and curved; basitarsal comb longitudinal. Metasoma with syntergum, therefore without epipygium; cercal brush present anterior to cercus (Fig. 16 ).

Discussion.

As discussed by Desjardins (2007), Diparinae have a cercal brush anterior to the cercus (Fig. 16 ). This feature is not perfectly diagnostic however, because it can also be present in Spalangiidae and Neapterolelapinae , which are recovered as the sister group to Lyciscidae , and Herbertiidae (Cruaud et al., submitted). Spalangiidae differ in having the mesepimeron extending over the anterior margin of the metapleuron. Lyciscidae differ in having an exposed, rigidly sclerotized labrum, and in lacking a frenum (except in Solenurinae ). Herbertiidae differ in having at most 10 antennal flagellomeres, and in having an exposed, rigidly sclerotized labrum. In the features listed in the diagnosis, Cerocephalidae may appear similar to Diparidae , although they differ in that Cerocephalidae have an intertorular prominence and at most 10 antennal flagellomeres. Diparisca remains in Diparidae as a genus of uncertain placement ( Mitroiu 2016), with distinction from Ceinae discussed therein.
