Taeniogonalos alticola (Tsuneki 1991)

Holotype of Taeniogonalos alticola, male, length of body 6.0 mm (of fore wing 5.4 mm). Head. Antenna incomplete, with 11 segments remaining; frons moderately punctate with smooth interspaces much wider than width of punctures; vertex sparsely punctulate and strongly shiny (Fig. 269), with rather long setae; temple largely smooth with few punctures at orbita (Fig. 273); head gradually narrowed behind eyes, eye in dorsal view nearly as long as temple (Fig. 269); occipital carina narrow, non-lamelliform, smooth (Fig. 269); supra-antennal elevations medium-sized (about 0.5 times as long as scapus), outer side distinctly oblique (angle about 45°) carinate and with few punctures and rugae (Fig. 269); area between elevations distinctly concave (Fig. 269); clypeus distinctly concave and thick medio-ventrally. Mesosoma. Length of mesosoma 1.5 times its height (Fig. 275); mesopleuron densely and finely obliquely rugulose, but smooth posteriorly, rather shiny; transverse mesopleural groove narrow, shallow and anteriorly crenulate; notauli narrow, rather deep and finely crenulate posteriorly; middle lobe of mesoscutum irregularly transversely rugose, lateral lobes rugulose laterally, coriaceous medially and with satin sheen (Fig. 274); scutellar sulcus complete, narrow and narrowly crenulate; scutellum rather flat and moderately rugose but smooth and shiny posteriorly, anteriorly near level of mesoscutum; metanotum medially distinctly convex and finely rugose (Fig. 274); propodeum comparatively slender and flat, anteriorly irregularly finely rugose and posteriorly largely smooth (Fig. 274); posterior propodeal carina distinctly arched, narrow lamelliform, foramen comparatively narrow (Fig. 274) and as high as wide basally. Wings. Fore wing: vein 1-M 1.4 times as long as vein 1-SR (Fig. 272), distinctly curved and vein 1-SR narrow anteriorly; second submarginal cell 1.5 times as long as third cell. Metasoma. First tergite 0.8 times as long as apically wide, smooth and with shallow wide depression medially (Fig. 276); second and following tergites superficially punctate and strongly shiny (Fig. 276); second sternite slightly convex, superficially and rather sparsely punctate (Fig. 278); third sternite without depression. Colour. Black or dark brown; outer orbita slightly brownish (Fig. 268); mandibles largely dark brown; palpi, pronotum postero-dorsally and tegulae brown; first tergite widely posteriorly and seventh tergite ivory (Fig. 276); antenna mainly, legs and pterostigma dark brown; fore wing membrane subhyaline (Fig. 272). Female. Unknown. Variation. Holotypes of Taeniogonalos minima and of Taeniogonalos similis are very similar to the holotype of Taeniogonalos alticola. Taeniogonalos minima has the antenna with 22 segments and longitudinal tyloids on 10th-13th segments (Fig. 283); mesoscutal lobes largely smooth and shiny or rugose; mesopleuron smooth (except antero-dorsally) to obliquely finely rugulose; seventh tergite brown or ivory; length of body 4.8-6.0 mm and of fore wing 4.4–5.4 mm.
