Face 1.2–1.35 × as broad as high, punctate, slightly convex medially in lateral view. Length of malar space 1.0–1.05 × as long as basal mandibular width. POL 0.9–1.2 × as long as OD. OOL 0.9–1.1 × as long as OD. Antenna with 41–44 flagellomeres. FL I 7.9–8.35 × as long as maximum depth in lateral view and 2.15–2.3 × as long as FL II.

Mesosoma densely punctate. Epomia present ventrally. Smooth area of mesoscutum extended to anterior to the line between each tegula ( Fig. 1 F View FIGURE 1 ). Scutellum largely smooth ( Fig. 11 C View FIGURE 11 ). Speculum with a small smooth area ( Fig. 12 D View FIGURE 12 ). Dorsal surface of propodeum punctate to rugose punctate. Fore wing length 6.6–7.2 mm. Areolet received vein 2m-cu slightly based of the outer angle. Nervellus subvertical, intercepted slightly posterior to the middle. Terminal tooth of fore and mid tarsal claws larger than other teeth ( Fig. 2 C View FIGURE 2 ). Hind femur 5.0–5.2 × as long as maximum depth in lateral view. Ratio of length of hind first to fifth tarsomeres 4.4–4.6: 2.0: 1.35–1.4: 0.65–0.7: 0.8–0.9. Hind second tarsomere 6.65 × as long as maximum depth in lateral view. All trochantelli without an apical tooth on the outer side. Hind tarsal claws each with an accessary tooth ( Fig. 2 R View FIGURE 2 ).

Metasoma. T I 4.0–4.4 × as long as maximum width, smooth with a few fine punctures. T II 1.65–2.05 × as long as maximum width. T II to T V coriaceous with fine and sparse punctures. Ovipositor sheath 1.5–1.7 × as long as hind tibia.

Coloration ( Figs 5 A View FIGURE 5 , 10 E View FIGURE 10 , 11 C, 12 C). Head black. Clypeus, a pair of markings of frontal orbit, malar space, mandible except for teeth, palpi and ventral surfaces of scape and pedicel yellow. Two pair of lateral spots of face and ventral surface of basal segments of flagellum reddish brown. Mesosoma and metasoma reddish brown. Postero-dorsal corner of pronotum, scutellum and subtegular ridge yellow. Antero-median part of mesoscutum, T V to T VII blackish brown to black. T II and T IV more or less tinged with blackish brown. Membranous part of metasomal sternites yellowish brown. Subgenital plate brown to blackish brown. Ovipositor reddish brown. Wings hyaline except for apical clouded area of fore wing. Veins and pterostigma blackish brown except for yellowish-brown wing base. Legs reddish brown to yellowish brown. Hind trochantellus, base and apex of hind femur, hind tibia, hind tibial spurs, basal part of hind first tarsomere and apical segments of hind tarsus more or less tinged with blackish brown.

Male (n = 13). Similar to female. Clypeus 1.6–1.8 × as broad as high. Length of malar space 1.1–1.2 × as long as basal mandibular width. POL 0.75–0.85 × as long as OD. OOL 0.5–0.7 × as long as OD. Hind femur 5.0–5.7 × as long as maximum depth in lateral view. T I 5.4–6.05 × as long as maximum width. T II 2.65–2.95 × as long as maximum width. Face, frontal orbit, lower part of gena, pronotum, propleuron, anterior part of mesoscutum except for median black area, mesopleuron and metapleuron yellow ( Figs 5 B View FIGURE 5 , 10 F View FIGURE 10 ).

Distribution. Japan (Amamioshima Is.).

Bionomics. Host unknown. Adults were collected in May, June, July, August, September and October.

Remarks. This species is endemic to Amamioshima Island. Insects from Amamioshima Island are usually found on Tokunoshima Island, which belongs to the same archipelago. The first author has intensively field sampling the ichneumonids in Tokunoshima Island on several years, but has not been able to find any specimens, including those in museum collections.
