Allophrys takemotoi Khalaim , sp. nov.

( Figs 10–17 )

Comparison. Differs from two other Japanese species of Allophrys by shorter upper mandibular tooth, polished temple, narrow rectangular basal area, lack of second recurrent vein (2 m-cu) and extremely short ovipositor (unknown for Allophrys sp.). See also Table 1 .

Description. Female. Body length 3.1 mm. Fore wing length 2.2 mm.

Head strongly narrowed, weakly rounded behind eyes in dorsal view; temple 0.55× as long as eye width. Clypeus lenticular, distinctly convex in lateral view, smooth ventrally to finely granulate dorsally, with a small median pit on lower margin. Mandible slender, with upper tooth about 1.5× longer than the lower tooth. Malar space almost as long as basal mandibular width ( Fig. 11 ). Antennal flagellum filiform, very slender, with 13 flagellomeres ( Fig. 11 ). Face, frons and temple impunctate; face very finely granulate and weakly shining; frons finely granulate, dull; temple polished. Occipital carina distinct laterally, dorsally not distinguished (head closely adjoining to mesosoma). Hypostomal carina complete, strong ( Fig. 12 ).

Mesosoma mostly finely granulate, impunctate and dull; mesopleuron centrally very finely punctate, almost smooth, weakly shining ( Fig. 13 ); dorsolateral area of propodeum almost smooth and weakly shining in upper part. Scutellum with lateral longitudinal carinae developed in its basal 0.3. Notaulus with rather strong wrinkle anterolaterally. Foveate groove short and broad, situated in anterior half of mesopleuron, strongly oblique, shallow, with very fine transverse wrinkles ( Fig. 13 ). Propodeum ( Fig. 14 ) with basal area narrow, impressed, indistinct, 0.35× as long as apical area; basal longitudinal carinae weak. Propodeal spiracle small, separated from pleural carina by 5.0× diameter of spiracle ( Fig. 13 ). Apical area ( Fig. 14 ) impressed along midline, narrowly rounded anteriorly, with weak transverse wrinkles posteriorly; apical longitudinal carinae strong, reaching transverse carina anteriorly.

Fore wing ( Fig. 15 ) with second recurrent vein (2 m-cu) virtually absent, only extreme hind end discernible. Intercubitus (2 rs-m) very short and very 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. Metacarpus (R 1) not reaching apex of fore wing. Second section of postnervulus absent, thus brachial cell is widely open posteriorly (as in genera Aneuclis Förster and Sathropterus Förster ). Legs slender.

First tergite slender, 4.4× as long as posteriorly broad, smooth, without glymma, with distinct dorsolateral carina in basal half. Second tergite 2.7× as long as anteriorly broad ( Fig. 17 ). Thyridial depression deep, about 2.5× as long as broad. Ovipositor very short, its sheath less than half length of first tergite ( Fig. 16 ).

Head and mesosoma black with slight brownish tinge. Palpi and mandible (teeth red) yellow. Lower 0.4 of clypeus reddish yellow. Antenna yellow basally to black apically. Tegula and pterostigma brown. Legs yellow, mid and hind coxa infuscate basally. Metasoma brown to dark brown.

Male. Unknown.

Etymology. The species is named in honour of the collector of the type specimen, H. Takemoto.

Material examined. Holotype female ( NIAES), Japan, Kyushu Region, Miyazaki Pref., Takaharu-machi, Miike , 20.V.1982, coll. H. Takemoto.

Distribution. Japan (Kyushu I.).
