Holotype, female (CNCI), labelled: [White] " Canada: AB, N of Twin Lakes, 27.VI. 2003, 639m 57 o 30.823'N 117 o 28.825'W Goulet, Carcamo & Otani"; [Red] " HOLOTYPE Peristenus braunae CNC No. 23474 " Condition of holotype: excellent. Allotype, male, with same data as holotype. Except for specimens from low elevation in coastal British Columbia, the remaining specimens, mentioned under "Material examined and range", are paratypes. Origin of species name. This species is named in honour of Lorraine Braun who reared this species from Lygus and helped to clarify a difficult part of the P. pallipes complex. Diagnosis. Clypeus black, punctures dense on head (between lateral ocellus and inner eye margin) and less dense on frons (surface smoother with shiny spaces between punctures), occurring in boreal region mainly after mid June. Description. FEMALE. Colour. Head and mesosoma black, clypeus usually black, metasoma usually black, rarely brown. Legs straw coloured or light reddish brown (metacoxa commonly brown or black (as in Fig. 5), uncommonly straw coloured). Metatibia light reddish brown and apical half often gradually becoming reddish brown, thus concolorous or almost so (as in Fig. 11). Metatarsomeres 1–5 as dark as apex of metatibia; palpi, tegula and mandible (except apex), straw coloured. Scape to flagellomere 2 straw coloured, then after flagellomere 3–4 brown to dark brown. Stigma uniformly dark brown or with a paler spot in basal half. Structure. Flagellum with 19–22 flagellomeres (respectively 14%, 51%, 31% and 4% of 106 specimens) and flagellomeres enlarged in apical 0.5 with at most 2 preapical flagellomeres quadrate or subquadrate. Genal length behind eye 1.00–1.31 times as long as length of eye. Height of eye 1.06–1.17 times as long as minimum distance between inner eye margins (as in Fig. 17). Maximum width of head behind eyes subequal (0.95–0.99) to maximum head width at eye level. ...
