Diagnosis. Both sexes of this species are readily distinguished by the dark band largely covering the anterior part of forewings, the deeply fuscous area is often extending largely over the first cubital cell. The female charac- teristically bears a prominent tubercle on the S3 apicomedially. The habitus is more elongated than in the other Korean Taeniogonalos species.

Description. Female. Body length 11.5 mm, forewing length 9.3 mm.

Head. SAEs yellow, with broad translucent apical lamella; in dorsal view, DSAE 0.33 × as long as distance between eyes at level of SAE. Occiput more or less concave medially but occipital carina narrow in its entire length (not broadened dorsdomedially, posterior margin of occipital carina also concave, fitting in occiput concavity). Frons, temple, vertex, and gena anteriorly punctate-reticulate; gena posteriorly densely punctate; occiput moderately punctate; clypeus densely punctate, but punctures smaller than those on frons; mandible sparsely punctate dorsally, densely punctate laterally (interspaces dully ridged).

Mesosoma. Entire length of notauli interrupted by thick keels. Almost entire mesosoma strongly, irregularly reticulate; posterior half of pronotal side longitudinally ridged; larger median propodeal declivity obliquely, sinuously ridged.

Metasoma. T1 0.5 × as broad as T2, without longitudinal depression. S1 1.1 × as broad as long. S2 not evenly convex in profile, weakly slopped in its anterior one-third, and more abrupt apically. T1 largely smooth medially, moderately to densely punctate laterally; T2 - 6 densely punctate; S1 - 3 densely punctate, S4 - 6 punctate-reticulate.

Coloration. Body largely black, following parts/markings deep yellow: lower frons lateral to inner orbits, genal stripes along lower two-third of outer orbits, anterior and posterior margins of pronotal dorsum, metanotum, narrow apical band of T1, broad apical band of T2 (ca. in apical one-third of T), small triangular apicomedian spot of T3, large hat-shaped spots of T4 - 5, almost entire T6, slender apical band of S1, paired lateral bands of S2, fore and mid trochanters, fore and mid femora apically, inner face of fore tibia, hind coxa apically, hind trochantellus and trochanter, and hind femur apically. Antennae and fore tarsus reddish to reddish yellow. Mandible and femora of all legs ferruginous.

Male. Much as in female except usual sexual dimorphic difference. Body length 10.3 mm, forewing length 7.8 mm. Antennae with tyloids as mentioned in the key. Apicomedian larger part of S2 more or less concave.

Biology. No breeding records are available for this rarely collected species. Adults appear in June and July, and are remarkably constant in size, a possible evidence for a more specialized range of hosts.
