Diagnosis
Mesosoma mostly reddish ( Fig. 25 View Fig A–B). Scutellum densely punctate. Basal part of hind tibia white ( Fig. 25A View Fig ). Apical part of fore wing infuscate.
Material examined
Holotype PHILIPPINES • ♀; Luzon , Mt Macolod; 24 Oct. 1953; H. Townes leg.; USUC.
Description
Female (holotype)
SIZE. Fore wing length 4.0 mm. Body short and stout, 1.35 times as long as high ( Fig. 25 View Fig ).
HEAD. Face 1.5 times as broad as high, centrally slightly convex, finely granulose ( Fig. 25C View Fig ). Clypeal suture indistinct. Clypeus slightly convex, matte, transversely striate, apically evenly convex downwards, with sharp apical margin. Mandible basally sparsely punctate; teeth blunt, of subequal length. Malar space granulated, 1.2 times as long as basal mandible width. Gena glossy, smooth and shiny, with no distinct carina dorsally between vertex and eye. Vertex ( Fig. 25D View Fig ) smooth to coriarious; posterior portion from behind ocelli to occipital carina slanted almost vertically, slightly concave. Postero-ocellar distance 5.2 times ocular-ocellar distance ( Fig. 25D View Fig ). Frons coriarious-rugose, lower portion slightly concave. Antenna slightly longer than body, with 27 flagellomeres, median portion moderately thickened.
MESOSOMA. Pronotum rugulose. Epomia indistinct. Mesoscutum wide and short, convex, with coarse and dense punctures. Notaulus distinct, reaching past half-length of mesoscutum. Scutellum convex, with coarse shallow punctures ( Fig. 25D View Fig ). Postscutellum transverse, smooth. Mesopleuron punctaterugose, with sparse, small, smooth areas, glabrate. Epicnemial carina long and curved in middle of mesopleuron ( Fig. 25B View Fig ). Sternaulus indistinct. Juxtacoxal carina indistinct from other metapleural rugae. Submetapleural carina complete. Fore wing with 1cu-a distinctly distad of M becoming Rs, 3rsm absent, distal abscissa of vein M spectral; ramulus absent; length of vein Cu equal to 2cu-a ( Fig. 25A View Fig ). Hind wing with cu-a strongly inclivous and interrupted at lower 0.2. Distal abscissa of Cu spectral. Distal abscissa of M spectral. Inner profile of fore basitarsus with basal half distinctly bent. Hind coxa punctate along lateral longitudinal portion, elsewhere smooth. Hind femur stout, 4.35 times as long as its maximum width. Basal portion of hind tibia slender, gradually thick toward apex. Longer spur of hind tibia 0.55 times as long as length of hind basitarsus. Propodeum steeply sloping in lateral view, with crowded coarse punctures, almost alveolate. Propodeal carinae indistinct except for vestiges of longitudinal carinae near insertion of T1.
METASOMA ( Fig. 25E View Fig ). T1 approximately 2.5 times as long as apically broad; petiole flat, smooth; postpetiole wide, with distinct punctures; median dorsal carina absent; dorsolateral and ventrolateral carinae distinct; spiracle small, round, not prominent. T2–T5 with coarse, adjacent punctures, almost alveolate. T2 widened posteriorly, approximately 0.6 times as long as apically broad. T3 approximately 0.6 times as long as apically broad, parallel-sided. Ovipositor 0.9 times as long as hind basitarsus.
COLOUR. Head and mesosoma mostly blackish, mesosoma mostly ferruginous. Head black; mouthparts fuscous and whitish; scape, pedicel and basal portion of flagellum light brownish, antenna dark brown towards apex. Mesosoma ferruginous; ventral portion of pronotum, fore coxa and trochanters dark brown; fore and mid femora basally brown, light brown towards apex. Fore tibia and tarsus light brown; hind tibia light brown with anterior face whitish on basal 0.7; mid tarsus light brown and whitish; hind trochanters, femur, apical 0.6 of tibia and T2–T5 dark brown; basal 0.4 of tibia and basitarsus whitish. Wings hyaline, with large apical infuscate band, but apical margin hyaline. Mesosoma mostly blackish; T1 ferruginous on anterioir 0.4; T2 light brown on anterior 0.6; T6–T8 whitish.
Remarks
This species is similar to P. striator ( Aubert, 1961) , from which it can be distinguished by the following combination of characters: mandibles sub-basally swollen, with a basal, transverse groove; propodeum sloping gradually; mesosoma mostly reddish ( Fig. 25A View Fig ); fore wing with one infuscate transverse band; antenna, scape and trochanters without white colouration.
Distribution
Philippines (Luzon), Japan (Okinawa).
