Material studied. Holotype male. CANADA, British Columbia, Vancouver I., Upper Carmanah Valley, Malaise trap, 12–27.VIII.1991, N. Winchester (in CNC). Paratypes. 3 males, same data as holotype (in MZH), 2 males, same data but 28.VIII–9.IX.1991 (in MZH), 3 males, same data as previous but 10–29.IX.1991 (2 in CNC, 1 in RBCM), 1 male, Vancouver I., Rocky Point, malaise trap, 29.IX.1994, N. Winchester (in MZH), 1 male, Vancouver, Horseshoe Bay, 30.V.1961, R. Vockeroth (in CNC).

Description. Male. Head. Brown, antenna paler brown, maxillary palpus very pale brown. Eye bridge 2 facets wide. Face with 5–8 scattered longer and shorter setae. Clypeus non-setose or with 1 seta. Maxillary palpus with 3 palpomeres; palpomeres of variable lengths; palpomere 1 with 1(2) long sharp seta, with a dorsal patch of sensilla; palpomere 2 with 1 long sharp seta and 5–8 shorter truncate setae, palpomere 3 with 6–11 short truncate setae. Body of antennal flagellomere 4 2.70–4.0x as long as wide, the neck shorter than broad, the longest setae longer than the width of flagellomere. Thorax. Brown, setae dark. Anterior pronotum with 4–7 setae. Episternum 1 with 4–11 setae. Wing. Length 1.6–2.5 mm. Width/length 0.40. R1/R 0.75–1.05. c/ w 0.70 –0.90. r-m and bM variable in length, r-m/bM 0.90–1.40, r-m with 1–2 dorsal setae, bM non-setose. Halter pale brown. Legs. Pale yellowish brown. Coxal setae dark. Front tibial organ in depression with vestiture in patch. Front tibial spur slightly longer than the tibial width. Abdomen. Pale brown, setae dark. Hypopygium, Figs 9 View FIGURE 9 A, B. Brown, concolorous with abdomen. Gonocoxa longer than gonostylus. Gonostylus slender with the mesial side impressed at apical half; apicomesially with a few elongated setae; with a large apical tooth, with 1–2 apical megasetae, with 2 mesial megasetae at the apical half, the mesial megasetae slightly larger than the apical ones, all long and nearly straight; with a flagellate seta basad of the mesial megasetae. Tegmen as long as broad, with sharp basolateral corners and sclerotized sides.

Discussion. In having a slender gonostylus with straight mesial megasetae, Camptochaeta winchesteri most resembles C. kajsae , but is distinguished in having these megasetae more apical in position, a much larger apical tooth of the gonostylus and a conical, laterally acuminate, not roundish, tegmen.

Etymology. The species is named after its collector, the Canadian entomologist Neville Winchester.
