Scutellum normally with 1 pair of setae, placed near or slightly behind middle of sclerite; if 2 pairs {Chrysonotomyia albiceps, some Chrysocharis moravica) or with several setae (Pediobius setigerus, P. multisetis) or without setae (Myrmokata) then frons (Figs 3,4) with an impressed line extending from antennal scrobes nearly or quite to eyes, this line placed about midway between toruli and median ocellus, or at all events not very close to the latter; this line sometimes V-shaped but may be nearly straight. Forewing: submarginal vein with 2 dorsal setae except in the African genus Myrmokata which has only 1 seta. Both maxillary and labial palpi usually 1-segmented. Notauli nearly always shallow posteriorly, or incomplete, rarely complete and deep throughout. Mandibles bidentate, bidentate with inner tooth serrulate, tridentate, or edentate. Antennae with 6-10 segments (one to three of these anelliform) ENTEDONTINAE Scutellum usually with 2 pairs of setae, occasionally with more than 2 pairs, or with several setae irregularly distributed (these setae are weak and difficult to see in some Euderinae). When the scutellum has 2 pairs of setae, or setae irregularly distributed, then the structure of the frons is different from that of Entedontinae (either without an impressed transverse line, or (Fig. 5) with a similar line very close to the median ocellus, or with an incomplete suture which does not reach the eyes). Forewing: submarginal vein with 1 to several dorsal setae. Maxillary and labial palpi 1- or 2-segmented. Notauli often complete and deep throughout. Mandibles tridentate, or with an acute outer tooth and a serrulate inner lobe, or edentate Forew
