Onega sanguinicollis (Latreille) comb. nov.

( Figs 1 G, 5)

Length. female 14.9 mm.

External morphology. Crown ( Fig. 1 G) with median length 6/10 interocular and 4/10 transocular length; apical and lateral concave areas on crown not confluent. Frons mostly concave. Pronotum ( Fig. 1 G) with posterior margin straight. Forewings ( Fig. 1 G) mostly opaque; membrane extending only over first apical cell; most of corium with plexus of veins, this absent on apical and brachial cells; clavus with crossveins between claval veins and between inner claval and claval margin. Hindlegs with femoral setal formula 2:1:1; first tarsomeres with length approximately equal to combined length of posterior ones. Other external characters as in generic description ( Young 1977: 285).

Female genitalia. Sternite VII with posterior margin with small median acute projection ( Fig. 5 A); fine transverse striations on disc. Pygofer ( Fig. 5 C) with few macrosetae distributed dorsally on anteapical region. Gonoplacs ( Fig. 1 C) with apex broadly round. Second valvulae ( Fig. 5 D) bearing 45 noncontiguous teeth; ventral prominence ( Fig. 5 F) slightly conspicuous. Other invariant generic characters as described above.

Coloration. Crown tan ( Fig. 1 G); pair of large semicircular areas on apical portion over muscle scars and posterior margin, dark­brown. Frons and clypeus dark­brown. Genae and lora castaneous. Pronotum and mesonotum ( Fig. 1 G) tan; pronotum with pair of faint castaneous stripes convergent anteriorly on posterior half; large triangular area on posterior 2/3 of pronotum and mesoscutellum, red; pair of maculae on anterolateral margin of pronotum behind eyes, anterior angles of mesoscutum, and apical margin of mesoscutellum, black. Forewings ( Fig. 1 G) dark red; clavus with basal half with translucent tan band along anal margin (continuous basally with small region of corium); membrane light brown. Thoracic pleura red, with small irregular tan and dark brown areas. Mesosternum mostly dark brown. Legs with femora mostly red; apical portions of femora and tibiae dark brown to black; tarsi dark brown with bases tan.
