Herbertiidae new status

Herbertiinae Bouček, 1988. Type genus: Herbertia Howard, 1894.

Diagnosis.

Antenna with 10 flagellomeres, including 3 clavomeres. Clypeus with transverse subapical groove. Labrum exposed, well-sclerotized, subrectangular with marginal setae in a row. Mandibles with 2 teeth. Subforaminal bridge with postgena separated by lower tentorial bridge; head posteriorly with postgenal lamina and postgenal groove ( Burks et al. 2018) (Fig. 22 ). Mesoscutellum with frenum indicated only laterally by the frenal arm, without axillular sulcus. Mesopleural area without an expanded acropleuron, with or without pits. Fore wing marginal vein more than 1.5 × stigmal vein length, without elongate uncus. Mesepimeron extending over anterior margin of metapleuron; two mesofurcal pits present. All legs with 5 tarsomeres; protibial spur stout and curved; basitarsal comb oblique. Metasoma with syntergum, therefore without epipygium.

Discussion.

The family Herbertiidae has uncertain placement based on both molecular (Cruaud et al., submitted) and morphological data, and is treated as incertae sedis in Chalcidoidea pending more consistent phylogenetic resolution. Micradelinae are similar to Herbertiidae in body shape, but differ in having an elongate uncus and much shorter marginal vein relative to the stigmal vein on the fore wing, in having an indicated axillular sulcus, in having only one mesofurcal pit, and in lacking a postgenal lamina and postgenal groove. Erotolepsiinae ( Spalangiidae ) are similar to Herbertiidae in habitus but differ in having a transverse anterior carina across Gt1, and in most species having a long carina encircling most of the face. Eunotidae differ in having a longitudinal basitarsal comb, and in lacking a postgenal lamina and postgenal groove. The presence of two mesofurcal pits is unusual, a feature shared with Moranilidae , Enoggerinae , Asaphesinae , some Eurytominae ( Krogmann and Vilhelmsen 2006) and Chalcididae ( Haltichellinae and Smicromorphinae , G. Delvare, pers. comm). Moranilidae differ in having an axillular sulcus. Other small-bodied families such as Pirenidae and Systasidae differ in having more than 2 mandibular teeth, and Pirenidae differ in having a concealed, flexible labrum.
