Holotype, ♀, JAPAN: Biwakubo-sawa, Masutomi, Hokuto City , Yamanashi Pref , 28. VII. 2007, Kyôhei Watanabe ( KPMNH [KPM-NK 55268]). Data on the label: “, // ( JAPAN) Yamanashi Pref. // Hokuto-shi, Masutomi, Biwakubo-sawa // 2007 July 28 // Kyohei Watanabe leg.”
Female ( HT). Body length 8.5 mm.
Coloration. Body ground color black and covered with short white setae; setae on head and mesoscutum brown. Scutellum with single white spot. Flagellum with white semiannulus on flagellomeres 6–10. Metasomal T 5– T 7 with apical white markings.
Head. Vertex and dorsal part of gena granulated and punctate; supra-clypeal area finely granulated with dense punctures and reticulate rugose; clypeus granulated and densely punctate ( Figs 3-A–C View FIGURE 3 ). Occipital carina meeting hypostomal carina above base of mandible by 0.2 × MBW. HW/HL = 2.1; OW/HW = 0.6; OOL/POL = 0.8. SCW/ SCH = 1.8; CLW/CLH = 1.9. MBL /BMW = 2.1; MSL/BMW = 0.9. MP 5/BMW = 1.4.
Antenna. Flagellum about as long as body length, with 35 flagellomeres; apical flagellomere conical; FL1 3.8 × as long as apical width and 1.3 × as long as FL2.
Mesosoma. Pronotum punctate; mesoscutum dull, densely punctate; dorsal and posterior surface of scutellum punctate; postscutellum polished, with sparse longitudinal rugae; mesopleuron and metapleuron densely punctate; surface of propodeum strongly punctate, except areola and petiolar area roughly rugose ( Fig. 3-C, D View FIGURE 3 ). Dorsal surface of scutellum moderately convex ( Fig. 3-G View FIGURE 3 ). Lateral carina of scutellum reaching posterior end ( Fig. 3-C View FIGURE 3 ). Costula very weak ( Fig. 3-C View FIGURE 3 ). MSSL / MSSW = 1.0; ARL/ARW = 1.0; ARW/PSD = 0.3; PSI = 1.5.
Legs. Surface of legs coriaceous, except coxae finely punctate. Hind tibia 0.4 × as long as fore wing.
Wings ( Fig. 4-B View FIGURE 4 ). Fore wing 7.6 mm long; areolet quadrangular, 1.2 × as long as 3rs-m, 0.4 × as high as 2m-cu; 1/M:2/M = 1.0:0.9. Cu-a opposite Rs&M; ramulus very slightly developed. Hind wing with cu-a 0.2 × as long as first abscissa of Cu1; three basal hamuli, 7 distal hamuli on R 1 vein.
Metasoma. Surface of petiole polished with sparse punctures; lateral area of petiole weakly rugose; median field of postpetiole polished, lateral field of postpetiole weakly rugose-punctate; T 2 strongly punctate except gastrocoelus and area between gastrocoeli roughly rugose; T 3 weakly densely punctate and coriaceous, T 4– T 5 coriaceous ( Fig. 3-E, F View FIGURE 3 ). Petiole in dorsal view almost parallel sided in basal half; postpetiole moderately widened; dorsomedian carina weakly developed; median and lateral field of postpetiole weakly separated ( Fig. 3-E View FIGURE 3 ). Posterior margins of T 5– T 7 slightly concave ( Fig. 3-E View FIGURE 3 ). T 1 L/W = 2.1; T 2 L/W = 0.9. THI = 1.6.
Male. Unknown.
Diagnosis: This species can be easily distinguished from other species of the genus by combination of: body entirely black except scutellum with single white spot; scutellum moderately convex; areolet quadrangular; T2 strongly punctate.
Distribution: Japan (Honshû).
Etymology: The new species is named after a great taxonomist of Darwin wasp, Dr Kyohei Watanabe, who collected the holotype.
Remarks: This species is probably rare, as only single specimen was found. The morphological characteristics, such as body sculpture and quadrangular areolet, are somewhat similar to L. gotoi Kusigemati, 1986 from Taiwan, although the colorations are different; in gotoi , head with broad yellow bands on each side of vertex to clypeus, pronotum and subalar ridge with yellow markings, and each femur, hind and mid tibiae reddish-brown. Considering by the morphological similarity with Oriental species, this new species might be found in southern part of Japan.
