Alaptus klonx Triapitsyn, sp. n.

Alaptus klonx Triapitsyn, sp. n. (Figs 74–81) Type material. Holotype female [UCRC] on slide (Fig. 76) labeled: 1. “USA, Florida, Jefferson Co., Monticello, University of Florida North Florida Research & Educa-tion Center, 315. viii.2002, R. Mizell, III, MT at forest edge”; 2. “ Mounted by V. V. Berezovskiy 2015 in Canada balsam ”; 3. [magenta] “ Alaptus klonx Triapitsyn HOLOTYPE ♀ ”; 4. “ Det. by S. V. Triapitsyn 2015 ”; 5. [database label] “ Univ. Calif. Riverside Ent. Res. Museum UCRC ENT 382897 ”. The Malaise trap that captured the holotype had been installed by S.V. Triapitsyn and V.V. Berezovskiy in the former University of Florida North Florida Research & Education Center in Monticello, Florida, and then was kindly maintained for several years by Russell F. Mizell, III. The holotype is dissected into many parts under 3 coverslips; missing are scape of one antenna as well as F5–F5 of the other antenna, and also one hind wing.

Head very dark brown; scape and pedicel yellowish-light brown, flagellum brown; mesosoma almost white laterally, mesonotum brown except anterior scutellum light brown; legs yellowish, gaster dark brown. Antenna (Fig. 74) about as long as body, with scape (including radicle) about 2.9× as long as wide and smooth; pedicel slightly longer than F1; F1 the shortest funicle segment, F2 a little less than 6.0× as long as wide and the longest funicle segment, F4 almost as long as F3 and longer than F5; clava about 4.8× as long as wide, with 4 mps, a little shorter than combined length of F3–F5. Mesosoma about 1.5× as long as wide. Fore wing (Fig. 75) about 8.5× as long as wide; disc with a slight brownish tinge and a complete row of 20 setae closer to anterior margin besides the admarginal rows; longest marginal seta 3.2× maximum wing width. Hind wing (Fig. 75) 17× as long as wide; disc more strongly infumate, with 1 row of setae closer to posterior margin; longest marginal seta 6.0× maximum wing width. Ovipositor (Fig. 77) longer than body, strongly exserted beyond apex of gaster (by about 0.5× its own total length), occupying its entire length, and 3.3× length of metatibia. Measurements (µm) of the holotype. Body (measurement taken from the dry specimen prior to slidemounting) 347; gaster 326; ovipositor 571. Antenna: scape (including radicle) 70; pedicel 42; F1 38; F2 63; F3 52; F4 51; F5 45; clava 132. Fore wing 507:60; longest marginal seta 179. Hind wing 510:30; longest marginal seta 194. Variation (slide-mounted paratypes except when indicated otherwise). Body length (dry-mounted, critical point dried specimens) 460–480 µm. Scape (including radicle) 3.4× as long as wide; pedicel about as long as F1; clava 3.6–5.1× as long as wide. Fore wing 8.1–8.6× as long as wide; disc with a complete row of 20–22 setae closer to anterior admarginal row (occasionally an additional seta present just behind the complete row of setae, near apex); longest marginal seta 2.9× maximum wing width. Hind wing with longest marginal seta 5.9× maximum wing width. Ovipositor 2.8–3.0× length of metatibia. MALE (paratype). Body length (slide-mounted specimen) 570 µm. Similar to female except for normal sexually dimorphic features and the following. Antenna (Fig. 80) with scape (including radicle) 2.8× as long as wide; all funicle segments longer than pedicel. Fore wing (Fig. 81) 7.8× as long as wide, disc with 3 or 4 additional setae behind the complete row of setae in the widest part; hind wing 17× as long as wide. Genitalia as in Fig. 78. Diagnosis. Female of A. klonx is characterized by a very long ovipositor, which is longer than body and exserted beyond the gastral apex by about 0.5× its total length and 2.8–3.3× length of metatibia, and also by the fore wing disc with a complete row of 20–22 setae closer to the anterior margin. In two similar Holarctic species with very long, notably exserted ovipositors, A. terebrans and A. longicaudatus, the former has the ovipositor shorter than body, 2.2–2.6× (but in the tentatively identified specimens from the USA 2.8–3.0×) length of metatibia, and exserted at most by about a third of its total length, whereas in the latter it is 3.7–3.9× length of metatibia and exserted by about 0.7× its own total length. Alaptus klonx, which has the mesosoma almost white laterally (Fig. 79), is definitely more similar to A. terebrans whose mesosoma is always brown laterally. Etymology. The species name is a noun in apposition and a combination of letters without any meaning. Hosts. Unknown.
