Alaptus longicaudatus Lou, Cao & Lou, 1999 View in CoL
( Figs 82–85 View FIGURES 82 – 85 )
Alaptus longicaudatus Lou, Cao & Lou 1999: 430 View in CoL –431. Type locality: Jingpo (as “Jingbo”) Lake (ca. 44°N 129°E), Ningan Co., Heilongjiang, China . Holotype female [ Shenyang Agricultural University , Shenyang, Liaoning, China] (not examined).
Material examined. RUSSIA: PRIMORSKIY KRAY, Ussuriyskiy rayon, Gornotayozhnoye, M.V. Michailovskaya: 24.vii–1.viii.1999 [1 ♀, UCRC] ; 12–17.viii.1999 [1 ♀, UCRC]; 15–17.vii.2000 [1 ♀, ZIN]; 11– 20.viii.2000 [1 ♀, UCRC]; 24–30.vii.2003 [1 ♀, UCRC]; 11–15.viii.2003 [1 ♀, IPBV].
Redescription. FEMALE (non-type specimens from Primorskiy kray, Russia). Body length (slide-mounted specimens) 580–630 µm. Head brown to dark brown (vertex); antenna yellowish-light brown except clava brown; mesosoma and metasoma brown except apical gastral terga a little darker, ovipositor sheath yellowish, and ovipositor dark brown; legs yellowish-light brown.
Vertex faintly transversely striate. Antenna ( Fig. 83 View FIGURES 82 – 85 ) a little shorter than body, with scape (including radicle) 2.7–3.0× as long as wide and smooth; pedicel either slightly shorter than F1 or about as long or slightly longer; F2 4.0–4.5× as long as wide, either a little longer than or about as long as F1, the following funicle segments a little shorter; clava 4.7–5.1× as long as wide, with 4 mps, usually a little shorter than (but sometimes about as long as) combined length of F2–F5.
Mesosoma ( Fig. 82 View FIGURES 82 – 85 ) 1.2–1.3× as long as wide. Midlobe of mesoscutum finely reticulate, with adnotaular seta rather long (36–42 µm); axillar seta also long (33–45 µm); frenum of scutellum with larger, fine longitudinal striations. Fore wing ( Fig. 84 View FIGURES 82 – 85 ) 8.2–8.9× as long as wide; disc with a slight brownish tinge (more so basally) and a complete row of 21–25 setae closer to anterior margin as well as from 1 to several additional setae behind it, besides the admarginal rows; longest marginal seta 3.1–3.4× maximum wing width. Hind wing ( Fig. 85 View FIGURES 82 – 85 ) 18–19× as long as wide; disc more strongly infumate, with 1 median row of setae; longest marginal seta 6.6–7.0× maximum wing width.
Gaster ( Fig. 82 View FIGURES 82 – 85 ) longer than mesosoma. Ovipositor longer than body, strongly exserted beyond apex of gaster (by about 0.7× its own total length), occupying at least 0.9× its length (often its entire length), and 3.7–3.9× length of metatibia.
MALE. Known, see Lou et al. (1999).
Diagnosis. Female of A. longicaudatus is distinctive due to its very long ovipositor ( Fig. 82 View FIGURES 82 – 85 ) which is strongly exserted beyond the gastral apex (by about 0.7× its own total length).
Distribution. Palaearctic: China (Heilongjiang, Jilin) and Russia * (Primorskiy kray).
Hosts. Unknown.
Comments. Besides the holotype, this species was also described from the 5 female and 2 male paratypes ( Lou et al. 1999) from Heilongjiang and Jilin provinces of China. The specimens from the Russian Far East, which were collected within 250 km from the type locality, match quite well the original description and illustrations of Lou et al. (1999).
