Diagnosis. Both sexes of this species are easily identified by the apical bands or paired triangular markings on terga that appear bi-colored (the usual yellow markings being outlined anteriorly with bright reddish-orange markings). In a male specimen of this species, forewing is infuscate anteriorly and forms an unusual continuous band as in Fig. 6C. But DC1 is not fuscous, unlike in T. subtruncata . Description. Female. Body length 9.5 - 12.5 mm, forewing length 8.0 - 11.0 mm.

Head. In dorsal view, DSAE 0.33 × as long as distance between eyes at level of SAE. Occipital carina narrow in its entire length. Almost entire face of head punctate-reticulate; clypeus and mandible densely punctate; occiput with tiny, sparse punctures.

Mesosoma. Notauli without distinct transverse keel, at most apically with a few weak bottom keels. Propleuron densely punctate; msoscutum and scutellar disc punctate-reticulate to irregularly reticulate; scutellar trough longitudinally ridged to irregularly reticulate; pronotal side punctate-reticulate to punctate-obliquely ridged; mesopleuron except posterior marginal part punctate-reticulate, or punctate-reticulate medially and obliquely ridged in its anterior and posterior declivities; metapleuron densely punctate to mostly ridged longitudinally; propodeum irregularly reticulate, often reticulae weaker (than those on mesoscutum) or transversely ridged dorsomedially, with smooth area above foramen.

Metasoma. T1 0.6 × as broad as T2, T2 without longitudinal depression. S1 1.3 × as broad as long. S2 more or less evenly convex in profile, highest submedially. T1 smooth; T2 - 6 punctate-reticulate except anteromedial smooth area; S1 moderately punctate, S2 densely punctate, S3 - 6 punctate-reticulate.

Coloration. Body extensively colored, following parts/ markings reddish orange, often tinged with deep yellow: all transverse or longitudinal stripes on frons and vertex connecting each other as in Fig. 6A and B (also refer to key herein), posterior half of dorsal mesopleuron, at least upper half of occiput, gena except posterior lower marginal part, lateral margins of median lobe of mesoscutum, margins of lateral lobes of mesoscutum, lateral margin of scutellar disk largely to entire face of scutellar disk, and outer bands of yellow apical bands or paired triangular markings of T1 - 6. Following parts/markings yellow to deep yellow: scape, SAE, lower frons laterally, clypeus laterally, mandible mostly, pronotal dorsum, tegula, metanotum, sublateral spots of propodeal dorsum, apical bands of T1 - 3, paired apical triangular spots of T4 - 6, apical bands of S1 - 2, femora apically, and ventral faces of fore and mid tibiae. Antennal flagellomeres reddish brown.

Male (Fig. 6C - E). Much as in female except usual sexual dimorphic difference. Body length 8.3 - 10.5 mm, forewing 7.5 - 9.3 mm. F8 - 13 with tyloids developed in almost entire length of each F, sometimes F14 also with a dot-like basal one (Fig. 6D). Apical bands of terga slenderer than in female. In a male specimen (Fig. 6C), forewing anteriorly fuscous, but first discal cell hyaline.

Biology. No host record is available for this uncommon species. All specimens have been collected in June and July. In an area covered with a low deciduous natural forest (near Posoksa , Geumsan-gun, CB, South Korea), this species was found regularly flying in the openings of the vegetation that were covered with patches of vines climbing on the trees (vine thickets), forming a natural continuation of the canopy towards the ground. Most specimens collected in this situation were males attracted by the parts of the vegetation exposed to the sun. One female was collected during ovipositing on Vitis sp , about 2 m above ground .

This species seems to appreciate the forested areas, where it may prefer to occupy the lower parts of the canopy.
