Material studied. Holotype male. USA, Oregon, Benton Co., Mary’s Peak , northern ridge trailhead, 44.530104°N, 123.547080°W, along big log, Malaise trap, 9.IX–13.X.2014, S. Fitzgerald, 1 male (in MZH) ; same data but 13.X– 12.XI.2014, 2 males (in MZH and SDEI) .

Description. Male. Head. Face and antenna concolorous brown, maxillary palpus very pale brown. Eye bridge 2–3 facets wide. Face with 5–6 scattered longer and shorter setae. Clypeus with 1 dark seta or non-setose. Maxillary palpus with 3 segments; 3rd segment longer than 1 st segment , 2nd segment shortest; 1 st segment with 1 long sharp seta, with a shallow irregular pit of sensilla; body of 4th antennal flagellomere 4.3x as long as wide, surface smooth, neck as long as wide, longest setae longer than width of flagellomere. Thorax. Brown, setae dark. Anterior pronotum with 3–4 setae. Proepisternum with 4–5 setae. Wing. Fumose. Length 2.2 mm. Width/length 0.40. Anal lobe moderate. R1/R 1.1. c/w 0.80. Veins distinct; stM slightly shorter than fork of M, bM slightly shorter than r-m, r-m with 1 dorsal seta, bM non-setose. Halter pale brown. Legs. Pale brown. Coxal setae dark. Fore tibial organ with dark vestiture in large demarcated patch in depression. Fore tibial spur subequal to width of tibia. Abdomen. Pale brown, setae dark and rather long and slender. Hypopygium ( Fig. 4 A ). Brown, concolorous with abdomen. Gonocoxa longer than gonostylus, gonocoxae separated, with rather short medial setosity. Gonostylus ( Fig. 4 B ) narrow, slightly widened towards apex, with the ventromedial side strongly impressed; apicomesially with a few elongated setae; with curved apical tooth, with a megaseta on the dorsal side of apical tooth, 1 megaseta in subapical on the ventral side of the base of tooth and one megaseta slightly more basal; megasetae subequal in length, nearly straight, slightly shorter than apical tooth, without basal bodies; a flagellate seta at middle of gonostylus. Tegmen subtriangular, with sublateral sclerotized stripes on the apical half, with an area of distinct aedeagal teeth. Aedeagal apodeme rather strong.

Discussion. See under Camptochaeta chilkatensis sp. n.
