Outer side of supra-antennal elevations comparatively steep (angle about 45°) and elevations about 0.5 times as long as scapus and area between elevations distinctly concave (Fig. 269); occipital carina narrow, non-lamelliform and smooth medio-dorsally or nearly so (Fig. 269); head anteriorly and posteriorly, mesosoma dorsally and pronotum laterally entirely black (Figs 268, 269, 274, 275); vertex largely smooth and strongly shiny (Fig. 269); mesoscutum weakly sculptured (Fig. 274); notauli crenulate posteriorly (Fig. 274); scutellum entirely black (Fig. 274); metanotum of male black medially (Fig. 274); fore wing of male subhyaline (Fig. 272; female unknown); propodeum comparatively slender (Fig. 274); propodeal foramen comparatively narrow and posterior propodeal carina distinctly arched (Fig. 274); first metasomal tergite with wide ivory band or pair of patches posteriorly (Fig. 276); second sternite of male slightly convex medio-posteriorly and entirely dark brown (Fig. 278); third sternite of female unknown; metasoma dorsally largely dark brown, only first tergite apically and seventh tergite ivory (Fig. 276).

Description. 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. Biology. Unknown. Collected in May. Distribution. China (Taiwan).
