Triapitsyn 2006”. The holotype ( Fig. 131 ) is in good condition, mounted dorsoventrally, with a pair of wings detached and mounted under a separate coverslip; missing are a clava of one antenna and a pair of wings . Paratype : same locality and collectors as the holotype except collected 16.vii.2001 (code SK-01-DJB-028C) [ 1 ♀ on slide, CAS ]. The type locality is in Sakhalinskaya oblast’ of Russia . Description. FEMALE ( holotype ). Head and gaster dark brown, mesosoma yellowish to light brown; appendages light brown except metacoxa brown. FIGURES 130–133. Alaptus plih sp. n. ♀ (holotype). 130, antenna; 131, body; 132, fore and hind wings; 133, slide. Antenna ( Fig. 130 ) shorter than body; scape (including radicle) 5.2× as long as wide, almost smooth; F1 shorter than pedicel and the shortest funicle segment, F2 the longest funicle segment and about 4× as long as wide, F3–F5 subequal in length, F4 and F5 the widest funicle segments; clava 3.8× as long as wide, apparently with 4 mps, as long as combined length of F3–F5. Fore wing ( Fig. 132 ) 9.3× as long as wide; disc slightly infumate and bare except the admarginal rows; longest marginal seta 4.0× maximum wing width. Hind wing ( Fig. 132 ) about 17× as long as wide; disc a little more strongly infumate, with 1 row of setae closer to posterior margin; longest marginal seta 6.2× maximum wing width. Gaster ( Fig. 131 ) longer than mesosoma. Ovipositor short, not exserted beyond apex of gaster, occupying about 0.4× its length, and a little more than 0.6× length of metatibia. Measurements of the holotype (µm). Body 466; head 112; mesosoma 173; gaster 215; ovipositor 188. Antenna: scape (including radicle) 79; pedicel 42; F1 30; F2 39; F3 33; F4 33; F5 33; clava 106. Fore wing 427:46; longest marginal seta 182. Hind wing 421:25; longest marginal seta 155. Variation ( paratype ). Body length 488 µm; fore wing 9.1× as long as wide, longest marginal seta 4.1× maximum wing width; hind wing about 18× as long as wide, longest marginal seta 6.6× maximum wing width; ovipositor a little less than 0.7× length of metatibia. MALE. Unknown. Diagnosis. Alaptus plih is most similar to A. pallidicornis and A. sp. near pallidicornis , from which it differs in the consistent body color patterns, as indicated in the key. Etymology. The species name is a noun in apposition and a combination of letters without any meaning. Hosts. Unknown. Comments. I also examined one specimen which could belong to this species: RUSSIA : PRIMORSKIY KRAY , Ussuriyskiy rayon, Gornotayozhnoye , 24.ix–5.x.1999 , M.V. Michailovskaya [ 1 ♀ , UCRC ] .
