Psilota pollinosa Young and van Steenis   sp. nov.

(Species plate: Fig. 29 View FIGURE 29 ; Genitalia: Fig. 45 View FIGURE 45 A–B; Map: Fig. 61B View FIGURE 61 )

Diagnosis: Metallic blue species with pleuron white pollinose and white pilose. Hind femur with a distinct rounded apicoventral setulose carina. Hind tibia simple. Body length: 9.8–13.2 mm.

Description: MALE: Head: Head black, face densely pale pollinose. Face and frons yellow pilose, vertex black pilose. Antenna usually entirely orange, rarely dull brown dorsally on postpedicel. Eye densely yellow pilose.

Thorax: Thorax dark, metallic blue. Legs partly dark brown, with apical half of fore- and mid femora often with an anterior orange streak, fore- and mid tibia partly to entirely orange-brown. Hind femur with a distinct rounded apicoventral setulose carina. Hind tibia simple, with no basoventral spur. Pleuron densely white pollinose. Pile on pleuron almost entirely white, with some individual black pile on the posterior anepisternum and anepimeron. Pile on scutum and scutellum entirely black. Wing colourless, with cells c, r, bm, cua, and the anal lobe mostly bare. Cells r 4+5, r 2+3, and dm with bare areas basally. Alula completely microtrichose. Halter orange-brown. Calypter pale brown to dark brown, always with a dark brown border. Abdomen: Abdomen metallic blue-green. Tergites 2 and 3 almost entirely white pilose, with only posterior margin black pilose, tergite 4 entirely white pilose. Sternites shining, white pilose. Genitalia: Epandrium compact, about as long as tall. Cercus approximately triangular. Inner lobe of surstylus inserted near top of inner lobe, bent sharply downwards at two-thirds its length, slightly swollen at apex. Inner lobe elongate, with a ventral bulge near base, excavated ventrally at one-third its length and then widening smoothly to apex. Phallapodeme smooth. Gonostylus thick, not darkened.

FEMALE: Identical except for normal sexual dimorphism.

Etymology: The specific epithet pollinosa   derives from “pollinosity”, the scientific term for the microtrichose hairs covering the cuticle of some body parts of Syrphidae   . This is in reference to the pollinose pleuron of Psilota pollinosa   sp. nov., which distinguishes it from Psilota coerulea   , Psilota smaragdina   sp. nov., and Psilota alexanderi   sp. nov.
