Material examined. JAPAN: [Honshu] 1 F, Shizuoka Pref., Kanaya, Fukuyo, 28 Sep. 1958, J. Minamikawa leg. (NARO).
Description based on Japanese specimen. Female (n = 1). Body length 11.0 mm, polished and covered with punctures and silver setae.
Head 0.55 × as long as wide. Clypeus 1.6 × as broad as high, smooth except for dorsal part sparsely punctate, slightly convex in lateral view. Face 1.6 × as broad as high, punctate, convex medially in lateral view. Frons largely smooth medially. Length of malar space 1.0 × as long as basal mandibular width. POL 1.0 × as long as OD. OOL 1.05 × as long as OD. Antenna with 51 flagellomeres. FL I 6.65 × as long as maximum depth in lateral view and 2.0 × as long as FL II.
Mesosoma densely punctate. Epomia absent. Mesoscutum without smooth area (Fig. 11 E). Speculum with a small smooth area. Dorsal surface of propodeum rugose punctate. Fore wing length 8.5 mm. Areolet received vein 2m-cu near the outer angle. Nervellus reclivous, intercepted posterior to the middle. Terminal tooth of fore and mid tarsal claws not larger than other teeth (Fig. 2 E). Hind femur 7.0 × as long as maximum depth in lateral view. Ratio of length of hind first to fifth tarsomeres 4.3: 2.0: 1.2: 0.6: 0.8. Hind second tarsomere 6.7 × as long as maximum depth in lateral view. All trochantelli without an apical tooth on the outer side. Tarsal claws without an accessary tooth (Fig. 2 T).
Metasoma. T I 4.2 × as long as maximum width, smooth with sparse punctures. T II 1.9 × as long as maximum width. T II to T V coriaceous with fine and sparse punctures. Ovipositor sheath 1.5 × as long as hind tibia.
Coloration (Figs 7 A, 10 I, 11 E, 12 E). Body (excluding wings and legs) black. Clypeus except for dorsal margin, facial orbit, frontal orbit, malar space, lower part of gena, mandible except for teeth, palpi, ventral surfaces of scape, pedicel and basal segments of flagellum, collar, postero-dorsal corner of pronotum, propleuron, a pair of markings of mesoscutum, scutellum, tegula, subtegular ridge, postero-dorsal corner and a small spot of mesopleuron, a C-shaped marking of metapleuron, each base of T I to T III, each posterior margin of T III to T VII, base of S I, membranous part of metasomal sternites and posterior margin of subgenital plate whitish yellow to yellow. Antenna with large white band subapically. Ovipositor reddish brown. Wings hyaline. Veins and pterostigma blackish brown except for yellowish-brown wing base. Fore and mid legs whitish yellow to yellowish brown, mid tarsus more or less darkened. Hind coxa yellowish brown except for apical dorsal black marking. Hind femur reddish brown except for black to blackish brown base and apical part. Hind tibia whitish yellow except for black to blackish brown base and apical part. Tibial spurs blackish brown. Hind tarsus whitish yellow except for base of first tarsomere blackish brown.
Male. No material is available.
Distribution. Japan (Honshu). Outside Japan, this species has been recorded from Korea (Yu et al. 2016).
Bionomics. Host unknown. Adult was collected in September in Japan.
Remarks. This is the first record of this species from Japan. This species closely resembles L. lepida and both species are found from Honshu in Autumn. In this study, we treat this species as a valid species because the character state of the hind tarsal claws (with or without an accessary tooth) is conspicuous and stable.
