Allophrys matsumurai Khalaim , sp. nov.

( Figs 1–7 )

Comparison. Differs from two other Japanese species of Allophrys by its distinctly punctate and smooth between punctures mesopleuron, and deep and long foveate groove with strong transverse wrinkles ( Figs 1, 2 ). It also differs from A. takemotoi sp. nov. by granulate temple and longer ovipositor, and from Allophrys sp. by occipital carina lacking dorsally. See also Table 1 .

Description. Female. Body length 4.3 mm. Fore wing length approximately 2.7 mm (both fore wings crumpled).

Head strongly narrowed, weakly rounded behind eyes in dorsal view; temple about half as long as eye width. Clypeus lenticular, convex in lateral view, smooth, with fine punctures in upper part. Mandible slender, with upper tooth 2.5× longer than the lower tooth. Malar space 0.8× as long as basal mandibular width ( Fig. 2 ). Antennal flagellum slender, slightly tapered towards apex, with 14 flagellomeres ( Fig. 2 ). Face, frons, vertex and temple granulate, dull, without distinct punctures. Occipital carina distinct laterally and absent dorsally. Hypostomal carina complete, strong.

Mesoscutum granulate, dull, with very fine dense punctures. Scutellum with lateral longitudinal carinae developed in its basal half. Notaulus with rather strong wrinkle anterolaterally. Foveate groove long, situated in anterior 0.8 of mesopleuron, S-curved, deep, coarsely crenulate ( Figs 1, 2 ). Propodeum ( Fig. 3 ) with basal area moderately broad, strongly widened anteriorly, 0.35× as long as apical area; basal longitudinal carinae well developed. Propodeal spiracle separated from pleural carina by about 2.5× diameter of spiracle ( Fig. 1 ). Apical area ( Fig. 3 ) impressed along midline, narrowly rounded anteriorly, transversely wrinkled posteriorly; apical longitudinal carinae strong, reaching transverse carina anteriorly.

Fore wings partly crumpled, therefore some characters of venation not discernible. Second recurrent vein (2 mcu) interstitial or slightly postfurcal, weakly pigmented anteriorly but distinct. Intercubitus (2 rs-m) moderately long, not unusually thick. Pterostigma large; first abscissa of radius (Rs +2 r) much shorter than width of pterostigma. First section of radius (Rs +2 r) distinctly curved, meeting with second section (Rs) at right angle. Hind wing with nervellus (cu 1& cu-a) weakly reclivous (less than 30°). Legs slender.

First tergite very slender, 5.8× as long as posteriorly broad, smooth, without glymma, with dorsolateral carina present only at extreme base. Second tergite 2.8× as long as anteriorly broad ( Fig. 4 ). Thyridial depression deep, about 2.5× as long as broad. Ovipositor short, with shallow dorsal subapical depression ( Fig. 5 ); its sheath 0.8× as long as first tergite.

Head black. Palpi, mandible (teeth dark red) and lower half of clypeus yellow. Antenna yellow basally to fuscous apically. Mesosoma mostly black; pronotum, propleuron and mesopleuron dark reddish brown. Tegula brown. Pterostigma dark brown. Legs yellow. First metasomal tergite dark brown. Metasoma behind first tergite yellow with extensive brown markings laterally, predominantly dark brown dorsally.

Male ( Fig. 6 ). Malar space very short, base of mandible almost touching the eye margin. Flagellum basally very slender, with 14 flagellomeres. Eyes strongly enlarged; anterior ocellus almost touching the eye margin, its maximum diameter less than shortest distance between inner eye margins ( Fig. 7 ). Occipital carina dorsally absent. Hypostomal carina strong, complete. Propodeum with basal area wider, basal longitudinal carinae somewhat stronger and apical area broader than in female. Tergites 1 and 2 much slenderer than in female. Thyridial depression very long. Mesosoma extensively dark reddish brown. Hind coxa basally brown. Metasoma brown to dark brown. Otherwise similar to female.
