Psilota auripila Young and van Steenis   sp. nov.

(Species plate: Fig. 10 View FIGURE 10 ; Genitalia: Fig. 40 View FIGURE 40 G–H; Map: Fig. 52A View FIGURE 52 )

Diagnosis: Face black, densely white pollinose, with white pile. Frons and vertex black pilose. Thorax black. Hind femur with a distinct rounded apicoventral setulose carina. Hind tibia with basoventral spur. Calypter with dark brown border. Halter pale, sometimes with knob slightly pigmented. Abdomen black. Anterior half of tergites 2 and 3 pale pilose. Body length: 7.1–12.2 mm.

Description: MALE: Head: Head black, face pale pollinose. Face pale pilose. Scape and pedicel orangebrown, postpedicel brown. Postpedicel triangular, approximately 1.5 times as long as widest point. Eye densely brown pilose. Thorax: Thorax black. Legs variable, ranging from mostly orange to almost entirely dark brown, with only apices of femora and bases of tibiae orange. Hind femur with a distinct rounded setulose carina. Hind tibia with a basoventral spur. Pleuron densely grey pollinose. Pile on anepisternum and anepimeron mixed black and white, pile on remainder of pleuron white. Pile on scutum mixed black and yellow anterior to transverse suture, usually entirely black posterior to suture. Scutellum usually entirely black pilose, with only scutellar fringe pale pilose. Wing colourless. Wing bare on anterior three-quarters of cell bm and one-quarter of cell cua, cell c bare on basal one-third. Alula completely microtrichose. Halter pale, sometimes with knob slightly pigmented. Calypter with border dark brown, upper calypter hairs brown, lower calypter hairs yellow. Abdomen: Abdomen black. Tergites 2 and 3 white pilose on anterior two-thirds, and black pilose on posterior one-third. Tergite 4 with mixed black and white pile. Sternites black, with white pilosity. Genitalia: Epandrium compact, about as long as tall. Cercus approximately triangular. Outer lobe of surstylus inserted just above mid-height on inner lobe, curved downwards on apical onethird, with apex of lobe thickened and curved slightly backwards towards base of surstylus. Inner lobe of surstylus broadening over entire length, with a slight ventral excavation at midlength, rounded at apex. Phallapodeme smooth. Gonostylus thick, not darkened.

FEMALE: Similar to male aside from sex-specific differences. Pile on thorax much shorter than male, pile of scutum entirely yellow to entirely black.

Etymology: The specific epithet ‘ auripila   ’ consists of auri -, derived from the Latin for “gold” or “lustre” (‘aurum’), and -pila, derived from the scientific term “pile”, which refers to the hair-like structures covering some tergites in Syrphidae   . This is in reference to the bright, pale pile on the face of Psilota auripila   sp. nov. that distinguishes it from similar species, Psilota spathistyla   sp. nov. and Psilota nigripila   sp. nov.

Discussion: Psilota auripila   sp. nov. exhibits more variation in COI sequence divergence, pleural pile, and leg colouration than most Psilota   species, and may represent a complex. However, no definite characters could be found to reliably separate genetic entities, and so it is here treated as a single species.
