description: Allophrys daklaka Khalaim, sp. nov.
(Figs 1–3)
Comparison. Allophrys daklaka is similar to A. davichia as both possess a broad pterostigma in the form of an almost equilateral triangle (as in Fig. 9) (distinctly elongated in the other two Vietnamese species) but differs from this and other Vietnamese species of Allophrys by the combination of short malar space, flagellum with 14–15 flagellomeres (Fig. 2), distinctly punctate mesopleuron with long and broad foveate groove (Fig. 1), and short basal area of propodeum (Fig. 3).
Description. Female. Body length 3.5 mm. Fore wing length 2.3 mm.
Head strongly tapered, weakly rounded behind eyes in dorsal view; temple 0.5× as long as eye width. Clypeus 3.0× as broad as long, lenticular, slightly convex in lateral view, separated from face by sharp groove, smooth, with fine inconspicuous punctures in upper part. Mandible slender, with upper tooth much longer than lower tooth. Malar space 0.7–0.8× as long as basal mandibular width. Antennal flagellum slender, weakly tapered towards apex, with 14–15 flagellomeres (Fig. 2); second flagellomere 1.4–1.8× and subapical flagellomeres 1.1–1.3× as long as broad. Face, frons, vertex and temple granulate, dull, impunctate or with very fine inconspicuous (because of granulation) punctures. Occipital carina complete laterally and absent dorsally (Fig. 2). Hypostomal carina strong, complete.
Mesoscutum very finely punctate, finely granulate, dull. Scutellum with lateral longitudinal carinae present in its anterior 0.3–0.5. Notaulus with strong wrinkle. Foveate groove extending in anterior 0.7 of mesopleuron, strongly oblique anteriorly, deep and broad, with coarse transverse wrinkles (Fig. 1). Mesopleuron mostly smooth and shining, finely granulate peripherally, finely to rather distinctly punctate centrally (above foveate groove). Propodeum with short basal area (basal longitudinal carinae more or less distinct) which is about 0.3× as long as apical area, distinctly widened anteriorly (Fig. 3); dorsolateral area finely granulate, impunctate, dull. Propodeal spiracle separated from pleural carina by 1.5–2.5× diameter of spiracle. Apical area distinctly impressed along midline, pointed or narrowly rounded anteriorly (Fig. 3), sometimes with fine transverse wrinkles posteriorly; apical longitudinal carinae distinct, reaching transverse carina anteriorly.
Fore wing with second recurrent vein (2 m-cu) postfurcal, weakly pigmented in anterior half. Pterostigma broad, in the form of almost equilateral triangle (as in Fig. 6). Intercubitus (2 rs-m) slightly thickened. First abscissa of radius (Rs +2 r) weakly arcuate, shorter than width of pterostigma. First and second sections of radius (Rs +2 r and Rs) meeting at right angle. Metacarpus (R 1) reaching tip of the wing. Second abscissa of postnervulus present. Hind wing with nervellus (cu 1& cu-a) reclivous, slanted 45–50° from horizontal. Legs slender.
First tergite very slender, 5.5× as long as posteriorly broad, round in cross-section, polished, its upper margin in dorsal view more or less straight in basal 0.7 and arcuate in apical 0.3. Second tergite 2.6× as long as anteriorly broad. Thyridial depression 2.5–3.0× as long as broad. Ovipositor short and slender, weakly and evenly upcurved, with very shallow dorsal subapical depression; sheath about 0.8× as long as first tergite.
Head and mesosoma dark reddish brown. Palpi and mandible yellow, mandibular teeth dark red. Clypeus brownish yellow in its lower 0.4. Scape and pedicel of antenna yellow, flagellum yellow basally to dark brown apically. Tegula brown. Pterostigma dark brown. Wings slightly infumate with brown. Legs yellow. Metasomal tergites 1–3 brown, following tergites brown dorsally and ventrally and yellow laterally and posteriorly.
Male. Unknown.
Variation. Material from Vietnam is rather uniform with only minor variation in structure and coloration. Specimens from Indonesia have slightly enlarged propodeal spiracles and wings more strongly infumate with brown. Of the Indonesian specimens, one small female from Halmahera has mesopleuron entirely granulate, impunctate, and the female from Ceram has antennal flagellum pale brown basally and yellow apically.
Etymology. The species is named after the type locality, Dak Lak province of Vietnam.
