Description

Male (holotype)

Head: Eye hairs brown, except white and sparser lower down; vertical triangle shiny black, only pollinose on the anterior corner; ocellar triangle with long black hairs; frontal triangle shiny black, with long, anteriorly directed, black hairs; antenna thinly pollinose, black; arista red; basoflagellomere 1.5 ¥ longer than the pedicel; scape conspicuously shorter than the basoflagellomere ( Fig. 52 ); bf = 2.1; face straight between the bottom of the frontal prominence and the mouth edge, only the facial tubercle protruding; area just below the antennae narrowly yellow; face extensively shiny black, white pollinose on a narrow band along the eye margin (this band reaches the frontal prominence, above, and the gena, below, where it is interrupted for a short distance to continue along the eye margin up to the lower third of the occiput); face with long light-yellow hairs except for a central bare stripe extending from the antennae to the mouth edge.

Thorax: Scutum with two faint medial pollinose stripes extending beyond the TS; lateral pollinose stripes as well as the pollinose spots near the PP very faint, almost absent; scutum with slightly posteriorly directed red hairs, except for the black hairs on the lateral margins; PP with black setae; PAPT posterodorsally, NP, and AEP only with black hairs, denser on PAPT posterodorsally and NP; anterior spiracle dark brown; posterior spiracle light brown; darkbrown scutellum, black laterally and with long red hairs; legs extensively black, only metatibia apically and mesobasotarsomere red dorsally (metabasotarsomere dark red dorsally); legs mostly with black hairs, only with red hairs on tibiae, tarsi, and some reduced areas of the metafemur; wings heavily darkbrown pigmented on the anterior half (pigmented area tapering towards the wing apex) ( Fig. 69 ); cells BM and CuP with lower density of microtrichia than other cells; calypter black.

Abdomen: Shiny black, mainly covered with short black hairs, except for the moustache arrangement of golden yellow hairs on tergum I; tergum II with long black hairs on the lateral margins, shorter when more posterior on the tergum; sterna with both long red and black hairs.

Genitalia: Shape of the superior lobes and surstyli as depicted in Figures 70–72 .

Female

Same as the male except ocellar triangle with long anteriorly directed black hairs; frons with an anteriorly directed chevron of pollinosity, and, posterior to the chevron, a pollinose area of about the pedicel length along the eye margin; frons with long erect and laterally directed white and black hairs intermixed on the pollinose area; frons with black anteriorly directed hairs between the pollinose area and the antennal insertion, as well as with a line of shorter white hairs on each eye margin; frontal prominence with the area surrounding the antennae narrowly yellow (each yellow marking sometimes shortly projects downwards); basoflagellomere about 1.5 ¥ longer than pedicel; medial pollinose stripes on scutum more conspicuous than in the male, and extending on about the anterior three-quarters of the scutum; scutum mostly with light-yellow hairs, but also with a few black hairs intermixed; PP, NP, PAPT, and AEP with both black and light-yellow hairs; legs mostly pale haired; wings with cells BM and CuP bare of microtrichia, and cells DM and CuA1 partially bare; terga II–III with more white hairs than those in the male, including on the lateral margins; sterna with long white hairs.

Etymology

The epithet ‘ zoricae ’ means ‘Zorica’s’, and refers to Dr Zorica Nedeljkovic´, a Serbian syrphidologist, and someone special to me.
