Jezonogonalos laeviceps (Tsuneki, 1991) comb. n., re-instated Figs 64-72

Taiwanogonalos laeviceps Tsuneki, 1991: 40. Synonymized by Carmean and Kimsey 1998 with Taeniogonalos maga Teranishi, 1929, and is here re-instated as valid species.

Type material.

Holotype, ♀ (OMNH) "[China:] Formosa, Arisan, 2-23.X.1918, J Sonan, M. Yoshino", " Taiwanogonalos laeviceps Tsuneki, ♂ [sic!], holotype".

Diagnosis.

Occipital carina wide lamelliform and only with a short carina medio-dorsally (Fig. 66); supra-antennal elevations entirely black; middle lobe of mesoscutum largely smooth (Fig. 69); propodeum with 1-2 transverse rugae medially (Fig. 69); second submarginal cell of fore wing small and narrowed anteriorly (Fig. 68); fore wing with more or less conspicuous dark brown patch below pterostigma (Fig. 68); metasoma of ♂ entirely black dorsally or nearly so, but apical 0.4 of first tergite largely ivory except medially (Fig. 71); first tergite 0.6-0.8 times as long as its apical width (Fig. 71); third sternite about 0.5 times as long as second sternite (Fig. 72).

Description.

Holotype (mutilated as indicated in original description), female (not male as indicated in original description!), length of body 6.5 mm (of fore wing about 5.0 mm).

Head. Antenna unknown [male antenna with 21 segments (including scapus) glued on card with longitudinal tyloids on 10 th– 15th segments is most likely of holotype of Taeniogonalos alticola ]; frons spaced punctulate; vertex largely smooth, sparsely punctulate and strongly shiny (Fig. 66), with rather short setae; temple largely smooth (Fig. 67); head gradually narrowed behind eyes, eye in dorsal view as long as temple (Fig. 66); 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 sparse punctures, latero-basally with pit-shaped depression (Fig. 66); clypeus slightly concave and thick medio-ventrally.

Mesosoma. Length of mesosoma 1.6 times its height (Fig. 70); mesopleuron below transverse mesopleural groove largely smooth but superficially rugulose anteriorly, above groove smooth but rugose anteriorly and no vertical groove (Fig. 70); transverse mesopleural groove wide, deep and widely crenulate; notauli narrow anteriorly, wide posteriorly and coarsely crenulate; mesoscutum largely smooth, spaced finely punctate and shiny, with some rugae posteriorly (Fig. 69); scutellar sulcus wide, both medially and laterally and coarsely crenulate; scutellum largely smooth (except some punctulation and medio-posteriorly coarsely crenulate) and shiny, longitudinally depressed medially and anteriorly above level of mesoscutum; metanotum medially hardly protruding, obtuse and smooth (Fig. 69); propodeum rugulose anteriorly (and sulcus medially widely crenulate and depressed), with smooth patches antero-laterally, with few transverse rugae medially (Fig. 69); posterior propodeal carina thick lamelliform and curved, foramen medially 0.6 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. 68); second submarginal cell of fore wing small and narrowed anteriorly.

Metasoma. First tergite 0.7 times as long as apically wide, smooth and with indistinct depression basally (Fig. 71); second and following tergites smooth and strongly shiny (Fig. 71); sternites mainly smooth; second sternite weakly curved in lateral view; third sternite about half as long as second sternite (Fig. 72).

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

Male. Unknown.
