Astarteserphinae subfam. nov.

Type genus. Astarteserphus gen. nov.

Diagnosis. The subfamily is diagnosed by the following combination of characters: Females with head broad, slightly wider than long; antennal toruli separated from clypeal base by about 3× torular diameter; scape short; flagellomere XI enlarged; compound eyes short, occupying upper portion of lateral head surface, hirsute, inner ocular margins roughly parallel; malar space elongate, nearly as long as compound eye and longer than mandible; mandible simple, without subapical teeth; maxillary palpus tetramerous; labial palpus trimerous; occipital carina wholly lacking (neither present dorsally nor laterally). Mesoscutum with notauli present as shallow furrows extending to posterior margin of mesoscutum; metepisternum without demarcated smooth polished area. Forewing with only Sc+R, pterostigma, and rrs as sclerotized veins; C absent, thus costal cell open along entire anterior length (marginal cell only closed cell); 3Rs nebulous, short, straight, forming short marginal cell shorter than pterostigma. Metasoma with metasomal tergum I and sternum I short, fused, forming short petiole, petiole visible from above; terga II–IV fused to form syntergum, with two faint furrows running transversely across syntergum indicating points of fusion between original terga II, III, and IV.
