Alaptus sp. near pallidicornis Foerster, 1856

( Figs 180–182 )

Material examined. GREECE: CENTRAL MACEDONIA, Lake Kerkini: Ecotourism site, 41°08’15.6’’N 23°13’01.2’’E, 65 m, G. Ramel: 23–29.v.2006 [1 ♀, UCRC] ; 30.v–5.vi.2006 [2 ♀, UCRC]. Kerkini Marsh , 41°13’32.8’’N 23°05’04.2’’E, 45 m, 21–27.iii.2007, G. Ramel [1 ♀, UCRC] .

Descriptive notes. FEMALE. Body length 383–412 µm. Head brown, mesosoma pale yellow except pronotum brownish, appendages and gaster pale ( Fig. 180 ). Antenna ( Fig. 181 ) about as long as body; scape (including radicle) 3.7–3.8× as long as wide, smooth; F1 a little shorter than pedicel, F2 the longest funicle segment and about 4.5× as long as wide, F3 almost as long as F1 and slightly shorter than F4, F5 the shortest and widest funicle segment; clava 3.8–3.9× as long as wide, apparently with 4 mps, a little longer than combined length of F3– F5. Mesosoma ( Fig. 180 ) about as long as wide. Fore wing ( Fig. 182 ) 9.2–9.8× as long as wide; disc almost hyaline and bare besides the admarginal rows; longest marginal seta 3.5–3.8× maximum wing width. Hind wing 14–16× as long as wide; disc more strongly infumate (more so basally), with 1 row of setae closer to posterior margin; longest marginal seta about 5.8× maximum wing width. Gaster just a little longer than mesosoma; ovipositor exserted slightly beyond apex of gaster, occupying about 0.7× its length, and 1.0–1.1× length of metatibia.

MALE. Unknown.

Diagnosis. Alaptus sp. is very similar to A. pallidicornis in lacking setae on the fore wing disc with the exception of the admarginal setal rows, from which it differs only in having a pale yellow mesosoma (except for the pronotum) and a pale gaster ( Fig. 180 ). I am reluctant to describe it as a new taxon, however, based solely on color.

Hosts. Unknown.
