Figs 15A–E , 112 , 144F

Diagnosis: This species can be recognized by the hind trochanter having a patch of short bristles ventrobasally ( Fig. 144F ); elongated surstyli with two lobes at outer margin before apex and a small, pointed edge in ventrobasal margin in dorsal view ( Fig. 15A ); both gonopods extended towards surstyli, rounded at apex; phallic guide with 3–4 short dorso- dorsolateral spines in ventral view ( Fig. 15D–E ).

Description: MALE: Body length: 2.8–2.9 mm. Head. Scape and pedicel dark, arista dark brown, flagellum light brown. Flagellum tapering. Face silvery pollinose. Frons, upper part shining black; lower part distinctly silver pollinose; eyes touching for distance equal to 2.2 times the length of ocellar triangle. Occiput silvery pollinose, less so on upper 1/3. Thorax. Postpronotum pale, with 3–4 dark bristles. Mesonotum (viewed obliquely from front) brown pollinose, anterior part of scutum more grey. Scutellum silvery brown pollinose with scattered dark bristles. Dorsocentral and supra-alar bristles short, dark, longer in frontal half, numerous pale bristles around postpronotum present. Halter, knob pale, tip brownish, stem light brown with 2 short bristles in upper side, base dark. Legs. Mid coxa with 3–4 long dark bristles. Fore and mid trochanters with 2–3 short bristles ventroapically. Trochanters brown, femora black, silvery pollinose posteriorly except shiny hind femur; knees and basal 1/6 of tibiae yellow (tibiae otherwise brown), tarsal segments brown dorsally, light brown ventrally. Hind trochanter with a batch of short bristles ventrobasally, brown pollinosity ( Fig. 144F ); one long ventrobasal bristle present on fore and 1–3 shorter bristles on mid femur. Hind femur without ventroapical spines. Subapical (distal) spines on first four tibiae present (short). Hind tarsomeres not flattened, hind metatarsus almost as long as 2–4 combined, dorsally all tarsomeres with erect bristles. Pulvilli shorter than last tarsal segment. Wing. Length: 3.0 mm. Upper side of basal costal cell with one long dark brown bristle. Fourth costal section 3 times as long as third costal section. Cross-vein r-m at middle of discal cell. 3–5 short dark setulae on tegula. Abdomen. Viewed obliquely from front tergites brown-black, tergite 1 silvery grey. Lateral bristles on first tergite present, 3–5 long dark bristles up to as long as ¾ of hind femur’s width at base. Genitalia. Genital capsule in dorsal view: epandrium as long as wide (MLE:MWE = 1.20). Surstyli elongated, with two lobes at outer margin before apex, curved to each other at apex, left surstylus is longer, both surstyli with a small pointed edge in ventrobasal margin ( Fig. 15A ). Genital capsule in ventral view: both gonopods extended towards surstyli, rounded at apex; phallic guide with 3–4 short dorso- dorsolateral spines; subepandrial sclerite large with some transverse sutures ( Fig. 15B ); Genital capsule in lateral view: both surstyli straight in basal half, strongly bent towards sternite in basal half; both surstyli with a pointed edge dorsobasally ( Fig. 15D–E ). Ejaculatory apodeme tube-like, bent, with a bulb in its middle ( Fig. 15C ).

FEMALE: Unknown.

Etymology: From the Greek bounites, dweller in the hills, in reference to the fact that all known specimens have been collected on hilltops. Many pipunculids go to hilltops to mate ( Skevington, 2008).
