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.

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].
