[magenta, cut in 2 parts] “ Alaptus huberi Triapitsyn HOLOTYPE ♀”. The type locality is Grenadier Island (central part) in the Thousand Islands National Park (abbreviated as St. Lawrence Islands National Park on the original label), Ontario, Canada. The holotype ( Fig. 42 ) is almost complete (lacking most of hind leg segments except metacoxa), in good condition, mounted laterally. Paratypes (on individual slides): CANADA: ONTARIO: Ottawa, West Carleton- March Ward (as Carleton Co. on the original labels), Constance Bay : 20.vii.1973 , G. Gibson (pan trap) [4 ♀, CNC]; 29.vi–27.vii.1978 , J. Redner, C. Dandale (pitfall trap) [1 ♀, CNC]. Thousand Islands National Park (as St. Lawrence Islands National Park), Grenadier Island (central part), E. Sigler: 16.vii.1975 [3 ♀, CNC]; 16– 23.vii.1975 [1 ♀, CNC]; 30.vii.1975 [2 ♀, CNC]. Description. FEMALE ( holotype ). Head and gaster dark brown, mesosoma notably lighter (light brown or brown); appendages pale brownish. Antenna ( Fig. 44 ) longer than body; scape (including radicle) 5.5× as long as wide, slightly longitudinally striate; F1 shorter than pedicel, F2 the longest funicle segment and about 2.5× as long as wide, F3 as long as F1 and F5 and slightly shorter than F4, F4 and F5 the widest funicle segments; clava 3.5–3.6× as long as wide, apparently with 4 mps, about as long as combined length of F3–F5 plus half length of F2. Fore wing ( Fig. 45 ) 11.5× as long as wide; disc almost hyaline and with a row of 2 setae medially besides the admarginal rows; longest marginal seta 4.5× maximum wing width. Hind wing 19× as long as wide; disc a little more strongly infumate, with 1 row of setae closer to posterior margin; longest marginal seta 6.5× maximum wing width. Ovipositor ( Fig. 42 ) not exserted beyond apex of gaster, occupying about 0.7× its length, and 0.8× length of metatibia. Measurements of the holotype (µm). Body 390; head 97; mesosoma 160; gaster 167; ovipositor 118. Antenna: scape (including radicle) 121; pedicel 48; F1 33; F2 38; F3 33; F4 36; F5 33; clava 132. Fore wing 450:39; longest marginal seta 175. Hind wing 439:23; longest marginal seta 151. Variation ( paratypes ). Body length 380–490 µm; scape (including radicle) 5.1–5.4× as long as wide; clava 2.7– 3.9× as long as wide; fore wing 10.6–11.0× as long as wide, with 1–3 setae in a median row, longest marginal seta 4.2–4.4× maximum wing width; hind wing 18–19× as long as wide, longest marginal seta about 6.0× maximum wing width. MALE. Unknown. Diagnosis. Alaptus huberi is most similar to A. eriococci , from which it differs by the morphological characters indicated in the key. Etymology. The species is named after John T. Huber who kindly loaned me its specimens from the CNC. Hosts. Unknown.
