Description
Camptochaeta subxystica sp. n.
Fig. 6 A‒C; plate III, fig. V
Locus typicus: Canada, Alberta, Munn Creek, 53.30°N, 118.10°W, spruce forest. Holotype: Male, 23.vii.‒15.ix.1994, leg. E. Fuller, Malaise trap (PWMP).
Description. Male. Head. Eye bridge 3 facets wide; antennae brown; 4th flagellomere with l/w-index of 3.0, haired as long as the diameter, neck rather short. Palpus short, 3-segmented, first segment with two bristles and a deep sensory pit. Thorax. Brown, coxae and femora paler; scutum is haired long, brownish; scutellum with two long bristles; posterior pronotum bare. Wings brownish; R1 = 3/4 R; c = 2/3 w; y = x; y without macrotrichia; posterior wing veins distinct, without macrotrichia. Haltere are rather long, brownish. Coxae, femora and tibiae brownish; tibial organ with a horseshoe-like patch of bristles; spurs of middle and hind tibiae equally long, somewhat longer than apex of the tibia wide; claws toothless. Abdomen. Hypopygium without an intergonocoxal lobe or a bristle patch, v-shaped; gonocoxites haired rather long but sparsely at the inner ventral margin; gonostylus strong, apical rounded broadly, concaved at the inner side; apical tooth short, basely broad and pale; gonostylus with 7 shorter spines: 3 above the tooth, one in the middle of the inner side, 3 below the middle. Tegmen with fine teeth and a rather short aedeagus. Body length: 2.8 mm.
Comments. The species is characterized by short and strong gonocoxites, long and strong gonostylus with a short and broad apical tooth (with pale base) as well as 7 shorter spines.
Camptochaeta subxystica sp. n. resembles Camptochaeta mimica Hippa & Vilkamaa, 1994 by gonostylus broadened towards the apex but it has a different arrangement of the gonostylar spines. In this respect it resembles Camptochaeta xysticoides Hippa & Vilkamaa, 1994 and Cam. abnormalis sp. n. Spines of Camptochaeta subxystica and Cam. abnormalis sp. n. are much shorter but the number of medial spines (4 not 3) is like in Cam. xysticoides Hippa & Vilkamaa, 1994. Cam. subxystica sp. n. differs from Cam. abnormalis sp. n. in having gonostylus apically broadened (subglobular in Cam. abnormalis sp. n.), regular gonostylar setosity (short and dense in Cam. abnormalis sp. n.) and a peculiar notch in its apical tooth, unknown in any other species of Camptochaeta.
Distribution. Canada (Alberta).
