Description

Size: Body length 5.7 to 7.0 mm; wing length 5.1 to 6.0 mm

Male: Head: Face mostly shiny black with scattered pollinosity along central midline of face and dense pollinosity adjacent to compound eye, mostly black pilose with a few white pili near the oral margin; frons and vertex black pilose; antenna almost entirely black, very slightly orangish-brown on ventral side, postpedicel 1.5 times as long as wide; eye densely yellow pilose.

Thorax: Scutum and scutellum shiny black, entirely black pilose; pleuron shiny black, pollen-free on anepisternum, katepisternum and anepimeron, other areas of pleuron with scattered pollinosity, pile almost entirely black, with pale pile only on ventral half of katepisternum; legs mostly black, with apices of pro- and meso femora, bases of pro- and meso tibia and ventral side of basitarsomeres dull orange; wing hyaline, with a small bare area at the base of cell c, anterobasal halves of cells bm and cua bare; alula completely microtrichose; halter orange; calypter pale brown, pile at edge of calypter brown.

Abdomen: Tergites black; tergite 1 yellowish-white pilose; tergite 2 with some white pile anteriorly, otherwise entirely black pilose; tergite 3 almost entirely black pilose, with a few scattered white pili; tergite 4 with mixed black and white pile, with posterior half of tergite entirely white pilose; sternites shining, white pilose.

Genitalia: Epandrium compact, about as long as wide; cercus subquadrate, with apex rounded and slightly wider at base; outer lobe of surstylus inserted at dorsal edge of of inner lobe, curved downwards smoothly over its entire length and narrowing slightly towards apex; inner lobe of surstylus broadening very slightly over basal ¾, expanding more abruptly to a rounded tip at apex; hypandrium narrowing smoothly towards apex; phallapodeme smooth, with ventral projection; postgonite thin, fused to hypandrium, with tip slightly expanded; phallus with a series of small, ventral spines.

Female: Similar to male, differing as follows: antenna more extensively orange, with only dorsal edge brown; face with pollen restricted to lateral edges, entirely free of pollen medially, pile entirely white; frons with mixed black and white pilosity; leg with orange areas more extensively orange, tarsomeres entirely orange ventrally; katepisternum with mixed black and white pilosity on dorsal half as well as ventral; calypter pale yellowish-white; tergite 2 with pile variable, ranging from entirely black throughout to white pilose anteriorly, with white pile not reaching lateral edge of tergite.

See Fig. 13.

Diagnosis

Entirely black, shining species with face and frons black pilose. postpedicel 1.5 times as long as wide. Scutum entirely black pilose, scutellum entirely black pilose, pleuron entirely black pilose except for some pale pile on ventral half of katepisternum. Tarsomeres dark brown. Hind coxa mostly white pilose. Tergite 2 mostly black pilose laterally. Sternite 1 shining. All sternites entirely white pilose.

Etymology

Named after John Klymko, who collected the holotype and suggested that it may be an undescribed species. John is a zoologist at the Atlantic Canada Conservation Data Centre, where he works on syrphids and many other animals.

Distribution

This species is known from six specimens from Quebec, New Brunswick and Pennsylvania.

Ecology

This rare species has been collected from late May to mid-June. It has been found in mixed woods at the edge of a clearing, in an area of pines and blueberries, on an open hilltop in mixed forest and nectaring on Pastinaca .

Taxon discussion

One COI barcode sequence of this species was obtained (Table 2 ).

Common Name

The common name given to the species by Skevington et al. (2019) is Black Haireye.
