Pseudolycoriella longisetosa sp. n.

( Fig. 1 D – E )

Locus typicus: USA, Arizona, Cochise County, Huachuca Mountains, Ash Canyon Road , 31.39°N, 111.24°W .

Holotype: Male, 22.–31.x.1993, oak-pine woodland, Malaise trap, leg. N. McFarland, ( PWMP).

Description. Male. Head: Round; eye bridge 3 facets wide. Antenna brown; 4 th flagellomere with a l/w index of 2.2, brownish, with hairs as long as the diameter. Palpi 3-segmented, long; first segment with 5–6 bristles and a flat patch of short sensillae. Mouth parts short. Thorax: Brown, scutum with short sparse hairs, some lateral and prescutellar bristles longer. Scutellum with 4 stronger bristles. Postpronotum bare. Wing brownish; R 1 = 2/3 R; c longer than 1/2 w; y = x, both bare; M-fork as long as M-stem, narrow; CuA-stem shorter than x; posterior veins distinct and without macrotrichia. Haltere short, brownish. Legs yellowish brown; tibial organ small, with row like bristles, weakly bordered. Claws toothed. Abdomen: Ventral base of hypopygium without lobe and bare; inner margin of gonocoxites with short sparse hairs in the proximal half and densely covered with long strong bristles in the distal half. Gonostylus broadly ovoid, densely haired apically, subapically with 3 fine hyaline spines and a long whiplash hair. Body length: 3.5 mm.

Comments. The species is characterized by having a large ovoid gonostylus with three fine hyaline spines, a longer whiplash hair and unusually long strong dense bristles in the distal half of the gonocoxites. It is similar to Psl. chlorothoracica sp. n., but differs from it by possessing long and strong bristles in the apical half of the gonocoxites, shorter spines on the gonostylus and uniformly brown antennae.

Distribution. USA (Arizona).
