(New SJN: Sumiiro-mame-togari-himebachi)

( Figs 41A–E , 65M , 66K )

Etymology. The specific name is from the Japanese term “Kuro ” (= black), which is the coloration of body and legs.

Description. Female (n=1). Body length 5.8 mm. Body covered with silver setae.

Head matt and densely punctate. Clypeus 1.8 times as wide as maximum length, its anterior margin rounded. MSL 0.9 times as long as BWM. OOL shorter than POL. OOL slightly shorter than and POL longer than OD. Occipital carina complete, its lower end joined with hypostomal carina distant from mandibular base. Upper tooth of mandible slightly longer than lower tooth. Base of mandible slightly convex. Antenna with 29 flagellomeres. FL III 4.0 times as long as maximum depth in lateral view.

Mesosoma polished. Lateral part of pronotum longitudinally striate medially, punctate dorsally and smooth ventrally. Epomia indistinct. Mesoscutum matt. Notaulus long, fading our just behind of the center of mesoscutum. Scutellum densely punctate and coriaceous, without a lateral longitudinal carina except for base. Mesopleuron longitudinally striate except for smooth speculum. Posterior transverse carina of mesosternum complete except for narrow indistinct area in front of mid coxae. Metapleuron punctures, without a juxtacoxal carina. Propodeal carinae complete ( Figs 41E , 65M ). Area basalis distinct ( Figs 41E , 65M ). Area superomedia distinct, transversely elongate, its length almost as long as area basalis ( Figs 41E , 65M ). Area petiolaris strongly elongated ( Fig. 41E ). Anterior part of propodeum largely smooth. Median part of propodeum partly longitudinally rugulose except for lateral smooth area. Posterior part of propodeum transversely rugulose. Postero-lateral corner of area dentipara weakly projected. Length of fore wing 4.2 mm. Areolet absent ( Fig. 41D ). Vein 2m-cu of fore wing with a single bulla ( Fig. 41D ). Nervellus inclivous, intercepted behind the middle ( Fig. 41D ). Hind femur 4.7 times as long as maximum depth in lateral view. Hind TS I: II: III: IV: V = 2.0: 0.9: 0.6: 0.3: 0.4. Tarsal claws simple.

Metasoma polished. T I 1.8 times as long as maximum width, longitudinally striate. Median dorsal carina of T I absent. Dorsolateral carina of T I partly indistinct. T II to T VI wider than long, finely punctate. T II partly covered with minute longitudinal striae. Ovipositor sheath 1.1 times as long as hind tibia. Ovipositor straight, without a nodus and with minute ventral teeth ( Fig. 66K ).

Coloration ( Figs 41A–E ). Body (excluding wings and legs) black to blackish brown. Base of FL I reddish brown. Mandible reddish brown except for darkened apex and base. Palpi and tegula whitish yellow. T II tinged with reddish brown postero-medially. Apices of T III and T IV narrowly tinged with reddish brown. Membranous part of metasomal sternites and ovipositor yellowish brown. Wings hyaline. Veins and pterostigma brown to dark brown. Fore and mid legs brown to yellowish brown except for white trochanters, trochantelli, tibial spurs, and base of tibiae. Hind coxa, femur, tibia, and tarsal segments blackish brown to black. Hind trochanter and trochantellus, and tibial spurs whitish yellow. Apex of hind coxa, bases of hind femur, tibia, and each tarsal segment tinged with yellowish brown.

Male. Unknown.

Distribution. Japan (Honshu).

Bionomics. Unknown.

Remarks. This species can be easily distinguished from other species by the black body, hind coxa, hind femur, hind tibia, and hind tarsus.
