Type material.

Holotype, ♂ (OMNH) "[China:] Taiwan, Habon, 1.V.1929, K. Sato", " Taiwanogonalos satoi Tsuneki, ♂, holotype".

Diagnosis.

Occipital carina wide lamelliform and with short carina medio-dorsally and some small carinae near it (Fig. 98); supra-antennal elevations entirely black; middle lobe of mesoscutum densely transversely striate (Fig. 103); propodeum with an irregular transverse ruga medially (Fig. 103); second submarginal cell of fore wing medium-sized, parallel-sided and laterally about as high as wide anteriorly (Fig. 101); fore wing with more or less conspicuous dark brown patch below pterostigma (Fig. 101); metasoma of ♂ black or dark brown dorsally or nearly so (Fig. 105); first tergite 0.8 times as long as its apical width (Fig. 105); third sternite about 0.4 times as long as second sternite (Fig. 107).

Description.

Holotype, male, length of body 6.9 mm (of fore wing 6.4 mm).

Head. Antenna with 24 segments, elliptical tyloids on 11 th– 15th segments (Fig. 100); frons spaced punctulate; vertex largely smooth, sparsely punctulate and strongly shiny (Fig. 98), with medium-sized setae; temple largely smooth (Fig. 102); head gradually narrowed behind eyes, eye in dorsal view 1.7 times as long as temple (Fig. 98); occipital carina wide lamelliform medio-dorsally with one short carina and few short sublateral carinae; supra-antennal elevations strongly enlarged (about 0.6 times as long as scapus), outer side subvertical and largely smooth except for a longitudinal groove and sparse punctures, latero-basally with depression (Fig. 98); clypeus rather concave and thick medio-ventrally.

Mesosoma. Length of mesosoma 1.6 times its height (Fig. 104); mesopleuron below transverse mesopleural groove largely smooth but superficially rugulose anteriorly, above groove smooth but rugulose anteriorly and with distinct crenulate vertical groove (Fig. 104); transverse mesopleural groove wide, deep and widely crenulate; notauli moderately wide and coarsely crenulate; middle lobe of mesoscutum densely transversely striate (Fig. 103), mesoscutum partly smooth and shiny, spaced punctate, with some striae posteriorly (Fig. 103); scutellar sulcus wide, both medially and laterally and coarsely crenulate; scutellum largely smooth (except some punctulation and rugae and medio-posteriorly narrowly crenulate) and shiny, longitudinally slightly depressed medially and anteriorly above level of mesoscutum; metanotum medially hardly protruding, evenly convex and smooth (Fig. 103); propodeum rugulose anteriorly (and sulcus medially widely crenulate and depressed), with irregular transverse ruga medially (Fig. 103); posterior propodeal carina thick, wide lamelliform and curved, foramen medially 0.7 times higher than wide basally.

Wings. Fore wing: length of vein 1-M 2.2 times as long as vein 1-SR and distinctly curved; veins r and 2-SR long (Fig. 101); second submarginal cell of fore wing medium-sized, parallel-sided and laterally about as high as wide anteriorly.

Metasoma. First tergite 0.8 times as long as apically wide, smooth and with wide depression basally (Fig. 105); second and following tergites largely smooth and strongly shiny (Fig. 105); sternites smooth, except for superficial punctures; second sternite weakly curved in lateral view; third sternite 0.4 times as long as second sternite (Fig. 107).

Colour. Black or dark brown; mandible (except apically), palpi (except basally), malar space largely, inner orbita very narrowly, pronotum latero-dorsally, tegulae, first segment laterally, large patch of second segment laterally, trochanters, trochantelli and base of femora ivory (Fig. 96); remainder of legs more or less brown (but coxae dark brown); pterostigma (but medially pale brown), veins and marginal cell (except apically) brown; remainder of wing membrane subhyaline.
