(Figs. 3, 98, 130)
Diagnosis. Separable from other members of the emarginatus group by the following characters: Occiput black, prementum reddish brown. Anterior margin of anepisternum shiny below spiracle. Fore leg with distal three tarsomeres brown; posterior face of fore femur covered with microtomentum. Mid tibia with row of anterodorsal bristles. Hind tibia without anteroventral bristle, with two ventroapical bristles. Wing without white spots. Postgonite without projection on posterior margin.
Description. Occiput black, posterior three-quarters of frons, gena, and prementum dark brown, face, antenna, and anterior quarter of frons orange to dark brown, maxillary palp yellow to brown (Fig. 3). Face sometimes with lateral corners and middle stripe below lunule darker. Mostly covered with microtomentum, frons with shiny spots lateral to ocelli, face with microtomentum below lunule and in dense crescent below antenna. Ocellar bristles just anterior to median ocellus. Subvibrissal bristle about 0.3X length of vibrissa, anterior genal bristle about 0.5X length of vibrissa.
Thorax black, mostly covered with microtomentum. Proepisternum shiny, anepisternum mostly shiny with microtomentum covering dorsal quarter and posterior third, katepisternum with a shiny spot behind fore coxa, meron and metapleuron shiny with band of microtomentum between posterior spiracle and hind coxa. Halter white, brownish below knob.
Legs black, joints, trochanters, and tarsi yellow, distal 3 tarsomeres of fore tarsus brown. Posterior face of fore femur covered with microtomentum. Fore basotarsomere with a small spur in male. Mid tibia with row of anterodorsals, 1 anteroventral, 1 posteroventral, 5 subapical bristles. Hind tibia with 2 ventroapical bristles.
Wing brown, veins dark brown, crossveins r-m and dm-cu pale.
Abdomen with tergites and sternites weakly sclerotized. Syntergite 1+2 with posterolateral corners and a thin band between them strongly sclerotized, tergites 3–4 with a thin posterior band moderately sclerotized.
Male postabdomen: Sternite 5 with sides straight, slightly wider at apex, posterior margin shallowly notched, anterior apodeme about as long as external portion, not keeled. Surstylus with distal portion longer than wide, lateral margins rounded. Pregonite fused with postgonite. Postgonite with straight posterior margin, boundary between lobes indistinct, posterior lobe long, rounded. Basiphallus expanded medially, without distinct epiphallus, preepiphallus long, transparent distally. Distiphallus with curved, spinose dorsal tube, blunt at tip, flanked by a single spike-like sclerite laterally (Fig. 98).
Female postabdomen: Tergites 6–7 wider than longer, sclerotized along anterior and lateral margins only. Sternites 6–7 mostly sclerotized, sternite 7 with a small unsclerotized spot medially. Tergites with 3 posterior strips, sternites with 2 posterior strips. Tergite 8 nearly square, slightly wider anteriorly, shallowly emarginated anteriorly, covered with microtomentum except anterior margin. Epiproct subtriangular, with wide anterior arms, 2 pairs of setae, with microtomentum medially. Cerci long, narrow. Sclerites of sternite 8 subrectangular, reaching anterior corners of sternite 8 laterally, anterior half shiny with a subconical proturberance. Hypoproct with an anterior notch, posterior margin and medial band moderately sclerotized. Spermathecae round, about as long as wide, with long apical invagination, sclerotized ducts about 1.5X longer than bulb.
