Description. Occiput black, face reddish brown, frons and gena intermediately coloured, antenna orange, prementum dark brown. Mostly covered with microtomentum, frons with frontal triangle and interfrontal plates mostly shiny, microtomentum around bases of postvertical bristles, microtomentum on orbital plates reaching bases of interfrontal setae, face mostly shiny, microtomentum on lunule and below base of antenna, gena with large median shiny spot. Subvibrissal bristle about 0.5X length of vibrissa, anterior genal bristle about 0.3X length of vibrissa.

Anterior postsutural dorsocentral bristle short in male, about 0.25X length of posterior dorsocentral.

Trochanters and mid tarsus yellow, fore and hind tarsi brown. Hind tibia with an anteroventral bristle, barely thicker but distinctly longer than surrounding setae, 3 ventroapical bristles.

Abdominal sternites 2–3 weakly sclerotized in male, sternite 4 black, heavily sclerotized, covered with tomentum.

Male postabdomen: Sternite 5 with curved lateral margins, widest medially, posterior corners projecting strongly and bearing tufts of long setae, posterior margin emarginated forming two shallow lobes, anterior apodeme about as long as external portion, pointed, with a dorsal keel. Surstylus scooped. Pregonite small, distinct. Postgonite with lobes well separated, anterior lobe rounded, posterior lobe acutely pointed. Basiphallus with short epiphallus, short, narrow preepiphallus. Distiphallus simple, with nearly straight, spinose dorsal tube ( Fig. 155 View FIGURES 155–160 ).

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 shallow cleft in anterior margin, strongly pinched medially, medial section and posterior margin covered with microtomentum. Epiproct with short anterior arms, shiny, with 1 pair of setae. Cerci broad. Sclerites of sternite 8 broad, subrectangular, pinched and sculptured medially, distal third with microtomentum. Hypoproct subrectangular, with anterior margin and posterior inverted triangle sclerotized. Spermathecae cylindrical, about 2X longer than wide, annulated, without invaginations, sclerotized duct about half as long as spermathecae.
