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. 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).

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.
