Protoita, gen. nov.
Diagnosis
Antenna 14-segmented (Fig. 3A, B); clava 1–3 segmented, terminal two flagellomeres differentiated by a line of weakness (partially fused) when clava multi-segmented (Fig. 3A, B); MPS present on all flagellomeres. Clypeus inflected dorsally and laterally with an arched groove at margin (Figs 6G, 7C, 8E, 10C). Malar sulcus present. Lower tentorial bridge present, about as broad as distance between lower margin of occipital foramen and dorsal margin of hypostomal foramen. Postgenal bridge absent (Fig. 5A). Pronotum dorsally narrow, almost entirely concealed by mesonotum medially in dorsal view (Figs 5D, 6C, 7A, 8B, 10D, 11D); lateral panel externally reaching base of tegula. Mesonotum about 4× as long as mesoscutellum (Figs 4D, 5D, 6C, 7A, 8B, 11D, 13A, 14A). Prepectus laterally evident as elongate, vertical sclerite partly covered by posterior-most margin of lateral panel of pronotum (Fig. 16A, B). Mesopleuron oriented dorsoventrally, abutting ventrally on a lower plane than coxae (Fig. 8B); mesodiscrimen deeply invaginated. Fore wing with basal vein completely sclerotized (Fig. 2A). M+Cu pigmented at least distally and usually sclerotized. Marginal vein strongly sclerotized and 2–3× as wide as submarginal vein. Parastigma usually as wide as or nearly as wide as marginal vein (Fig. 2A). Costal cell reaching far beyond junction of submarginal vein and basal vein. Retinaculum pigmented. Hind wing with three hamuli of equal length and orientation, the distal hamulus not extending beyond midpoint of hind wing. Meso- and metacoxae abutting, separated widely from procoxa by mesopleuron (Figs 6A, C, 8B, 11D, 13A). Protibial spur curved and apically cleft; probasitarus with basitarsal comb nearly always present (Figs 4C, 7D, 10E, 11F, 14D:cal). Metatibia with two apical spurs with shorter spur about ⅓ length of longer spur (Figs 8A, 9A, 11C). All tarsi 5-segmented; basitarsi about as long as or slightly shorter than tarsomeres 2–4 (Figs 4A, 5A, 6A, 8A, 10E, 11F, 15C). Metasoma with short petiole. Hypopygium reaching end of metasoma.
