Description. Head dark brown, occiput black, face and clypeus brown, antenna and prementum orange, maxillary palp yellow. Mostly covered with microtomentum, frons with shiny spots lateral to ocellar triangle, ventral half of face shiny. Ocellar and outer vertical bristles short, about 0.5X length of postocellar bristles, ocellar bristles just anterior to median ocellus, both pairs of orbital bristles present. Subvibrissal and anterior genal bristles about 0.3X length of vibrissa. Gena about 0.25X eye height. Labellum with 12 pseudotrachea.

Thorax black, entirely covered with microtomentum. Postpronotal, anterior notopleural, lateral postalar, and apical scutellar bristles long, posterior notopleural, lateral scutellar, and katepisternal bristles about half length, medial postalar bristle very short, other bristles absent. Wing and halter absent.

Coxae and hind femur and tibia black, fore and mid tibia, hind trochanter, and two basal tarsomeres of hind leg brown, trochanters, femora, and tarsi of fore and mid leg and three distal tarsomeres of hind leg yellow. Mid tibia with row of anterodorsal, 1 anteroventral, 1 posteroventral, and 5 apical bristles. Hind tibia with 1 anteroventral bristle at two-thirds to three-quarters, 2 ventroapical bristles.

Abdominal tergites black, heavily sclerotized, covered with microtomentum. Male with sternites 2–4 black, heavily sclerotized, covered with microtomentum, female with sternites 2–5 moderately sclerotized, covered with microtomentum.

Male postabdomen: Sternite 5 with lateral margins straight, posterior margin rounded with medial V-shaped notch, anterior apodeme long, reaching segment 2, without keel ( Fig. 67 View FIGURES 65–70 ). Surstylus bilobed, anterior lobe short, both rounded apically ( Fig. 66 View FIGURES 65–70 ). Pregonite large, not fused with postgonite. Postgonite narrow, without distinct lobes, tip excavated anteriorly. Basiphallus without epiphallus, preepiphallus short, transparent. Distiphallus with a strongly curved spinose dorsal tube ( Fig. 65 View FIGURES 65–70 ).

Female postabdomen: Tergites 6–7 heavily sclerotized along anterior and lateral margins, anterior margin shiny, not sclerotized medially, with 3 posterior weakly sclerotized strips. Tergite 8 with microtomentum covering posterior two-thirds. Epiproct with 1 pair of setae. Tergites 6–7 narrow, heavily sclerotized along anterior and lateral margins, anterior margin shiny, not sclerotized medially. Sclerites of tergite 8 subrectangular, anterior end pointed, posterior third with microtomentum and setae. Hypoproct trapezoidal, covered with microtomentum. Spermathecae sausage-shaped, about 2.5X longer than wide, annulated, with apical invagination, sclerotized duct about as long as spermathecae.

Comments. The species name is from the Latin bi (two) + flavus (yellow), referring to the yellow fore and mid femora. A few other species in the subfamily have orange or yellow fore femora, but only this species has the mid femur also yellow.
