Description. Head black, anterior margin of frons, face, and antenna reddish brown. Clypeus orange, maxillary palp yellow, prementum dark brown. Mostly covered with microtomentum, frons with frontal triangle and interfrontal plates mostly shiny, microtomentum around bases of postvertical bristles and a little at bases of ocellar bristles, may reach anteriorly from ocellar bristles, microtomentum on orbital plates reaching bases of interfrontal setae, face mostly shiny, microtomentum on lunule and below base of antenna, gena with microtomentum on ventral half and in a spot below eye. Subvibrissal and anterior genal bristle about 0.3X length of vibrissa.
Trochanters and tarsi reddish brown. Hind tibia with a long thin anteroventral bristle, 3 ventroapical bristles.
Abdominal sternites 2–3 weakly sclerotized, sternite 4 heavily sclerotized, black, covered with microtomentum in male.
Male postabdomen: Sternite 5 with curved lateral margins, widest medially, posterior corners narrow, projecting strongly and bearing tufts of long setae, posterior margin emarginated forming two distinct lobes, anterior apodeme about as long as external portion, pointed, with a dorsal keel ( Fig. 162 View FIGURES 161–165 ). Surstylus broad but slightly narrowed apically, scooped. Pregonite small, distinct. Postgonite with lobes well separated, anterior lobe rounded, posterior lobe longer, pointed. Basiphallus with short, broad epiphallus, short, narrow preepiphallus. Distiphallus simple, with nearly straight, spinose dorsal tube ( Fig. 161 View FIGURES 161–165 ).
Female postabdomen: Tergites 6–7 and sternites 6–7 wider than long, sclerotized along anterior and lateral margins only. Tergites with 3 posterior strips, sternites with 2 posterior strips. Tergite 8 with a deep cleft in anterior margin, strongly pinched medially, medial section and posterior margin covered with microtomentum. Epiproct with short anterior arms, shiny, with 2 pairs of setae. Cerci broad. Sclerites of sternite 8 broad, subrectangular, pinched and sculptured medially, posterior margins with microtomentum. Hypoproct subrectangular, with two anterior crescent-shaped patches and posterior margin sclerotized. Spermathecae cylindrical, about 2X longer than wide, annulated, without invaginations, sclerotized duct about half as long as spermathecae.
