Palpus with long white setae. Proboscis dark brown with white setae at base and apex. Orbital setae white. Ocellar setae white, less than length of scape. Postocular setae and macrosetae white. Lower occipital setae white.Antenna brown. Scape and pedicel reddish yellow at base, with white setae, pospedicel reddish yellow at base and in the middle. Style wide and beveled with seta-like sensory element; equal to 1/3 of scape length ( Fig. 18 ).

Thorax black. Median and paramedian stripes in presutural area of scutum and sutural area silvery tomentose. Scutum with wide stripe of silvery tomentum extending from anterior margin to scutellum in lateral view. Scutum with short white and black setae. Pleuron black, silvery tomentose and without setae, but katatergite with few white setae and macrosetae. Anepimeron reddish dorsally. Postpronotal lobe clearly reddish yellow, silvery tomentose and without setae. Postalar callus reddish with silvery tomentum. Scutellum reddish on margin, with 2 white apical macrosetae; disk silvery tomentose, without setae. Notum with 1 white dorsocentral seta or none. 2 notopleural, 2 supra- and 2–3 postalar setae white ( Figs 19–20 ).

Wings are darkened anteroproximally due to dense brown microtrichia along veins, veins brown ( Fig. 20 ).

Legs. Coxae reddish yellow, black laterally, silvery tomentose, with white setae and macrosetae. Trochanters reddish yellow with silvery tomentum. Fore femur reddish yellow with brown stripe dorsally and a light brown one ventrally, not reaching the apex. Mid and hind femora dark brown, reddish yellow at base and apex. Femora and tibiae with white setae. Fore and mid tibiae reddish yellow, dark brown at apex. Hind tibia reddish yellow at 1/3 of its length, dark brown distally. Tibiae with golden macrosetae, some of them brown at apex of tibiae. Fore and mid tarsi dark brown, hind tarsus black, with black macrosetae, some of them golden. Spine on fore tibia black. Claws dark brown, reddish yellow at base. Pulvillus well developed, reddish yellow, longer than 2/3 of claw length ( Fig. 21 ).

Abdomen. Tergites shiny black with white setae; tergite I with white macrosetae laterally. Tergites I–IV, sometimes V, with reddish brown stripe posteriorly in dorsal and lateral view ( Figs 20–21 ).

Hypopygium reddish brown, rotated 90 o to the right, with white setae becoming longer and denser towards the apex. Epandrium divided in the middle into two halves. Gonocoxite elongated, with two narrow process on posterior margin. Aedeagus elongated and curved in the middle. Apodeme of ejaculator large and rounded ( Figs 21–26 ).
