( Figs. 7 View FIGURES 5 – 8 , 18, 22, 25, 29, 84, 85, 124)
Diagnosis. Separable from other members of the emarginatus group by the following characters: Occiput black, prementum orange. Anterior margin of anepisternum with microtomentum below spiracle. Mid tibia with row of anterodorsal bristles. Hind tibia with anteroventral bristle just past half, with two ventroapical bristles. Wing without white spots. Male sternite 5 with deep V-shaped notch in posterior margin.
Description. Head orange, occiput black, ocellar triangle brown, prementum brown to dark brown. Ventral corners of face may be somewhat darker. Mostly covered with microtomentum, frons with shiny spots lateral to ocelli ( Fig. 29 View FIGURES 26 – 29 ), face mostly shiny with microtomentum below antenna and lunule. Ocellar bristles just anterior to median ocellus. Subvibrissal and anterior genal bristles about 0.5X length of vibrissa.
Thorax black, mostly covered with microtomentum. Proepisternum shiny, anepisternum with ventromedial shiny spot covering about three-quarters height and half length of sclerite, katepisternum with a shiny spot behind fore coxa, thin shiny stripe along margin of meron and metapleuron, metapleuron with a shiny spot in posteroventral corner ( Fig. 7 View FIGURES 5 – 8 ). Halter white, brownish below knob.
Legs black, joints and trochanters reddish brown, tarsi yellow except distal 3 tarsomeres of fore tarsus brown. 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 paler (Fig. 18).
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 ( Fig. 22 View FIGURES 21 – 23 ).
Male postabdomen: Sternite 5 long, lateral margins rounded, posterior margin with a deep V-shaped notch, anterior apodeme broad for most of its length with a pointed tip, with a prominent dorsal keel ( Fig. 85 View FIGURES 78 – 85 ). Epandrium fused between anal opening and cerci ( Fig. 25 View FIGURES 24 – 25 ). Surstylus paddle-shaped, anterior face covered with setae. Pregonite indistinct, fused with postgonite. Postgonite with distal portion narrow, lobes overlapping, both narrow, truncate, posterior lobe longer. Basiphallus with very broad epiphallus, narrow preepiphallus. Distiphallus with long dorsal tube, straight and with a few spines medially, flanked by a single spike-like sclerite ( Fig. 84 View FIGURES 78 – 85 ).
Female postabdomen: Tergites 6–7 sclerotized along anterior and lateral margins only, sternites 6–7 mostly sclerotized. Tergites with 3 posterior strips, sternites with 2 posterior strips. Tergite 8 covered with microtomentum except anterior margin, shallowly emarginated anteriorly and posteriorly. Epiproct with very short anterior arms, microtomentum medially, with 2 pairs of setae. Cerci long, narrow. Sclerites of sternite 8 subrectangular, broadened at apex, covered with microtomentum except anterior margin. Hypoproct subrectangular. Spermathecae barrel-shaped, slightly longer than wide, long apical invagination meeting basal invagination, sclerotized duct about as long as bulb.
