Description. Male. Head. Eye bridge 3‒4 facets wide; antennae brown; 4th flagellomere with l/w-index of 3.0, haired as long as diameter, neck rather short. Palpus are 3-segmented, first segment with one bristle and a deep sensory pit. Thorax. Brown, coxae and femora paler; scutum is haired rather long and brownish; scutellum with two long bristles; mediotergite with a few hairs; posterior pronotum bare. Wings brownish; R1 = 3/4 R; c = 2/3 w; y = x; y bare; posterior wing veins distinct, without macrotrichia. Haltere are rather long, brownish. Coxae, femora and tibiae brownish; tibial organ with a large horseshoe-like patch of bristles; spurs of middle and hind tibiae equally long, somewhat longer than the apex of tibia wide; claws toothless. Abdomen. Hypopygium without an intergonocoxal lobe or bristle patch; gonocoxites haired moderately long but sparsely on the inner ventral margin; gonostylus elongate, with flat inner side; the apical tooth (paler on the base) is longer than the 5 (6) shorter spines: 2 above the tooth, 4 below, inserting separately up to the middle of gonostylus. Tegmen is wider than long, apically rounded and laterally weakly winged, with fine teeth and a short aedeagus. Body length: 2 mm.

Comments. The species is characterized by elongate gonostylus with a flat inner side and an apical tooth, longer than the 5‒6 spines. It resembles Camptochaeta ofenkaulis ( Lengersdorf, 1925) from Europe and Camptochaeta jeskei Mohrig & Röschmann, 1993 from Morocco ( Röschmann & Mohrig 1993) by very narrow gonostylus, impressed at the inner side but differs in having 5‒6 medial spines (not 2), which are distinctly shorter than the apical tooth.

Distribution. Canada ( Alberta).
