Diagnosis. Length, 11.5 mm. Black except head entirely orange ( Fig. 24 ). Forewing uniformly lightly infuscated; hind wing somewhat paler on basal half ( Fig. 23 ). Antenna ( Fig. 29 ) with 14 or 15 antennomeres; length of first four antennomeres as 1.0:0.3:0.8:0.4. Sculpture on frons consisting of straight to irregular carinae, not reticulate ( Fig. 28 ). Head from above gently rounded behind eyes, distance behind eyes much longer than eye length ( Fig. 27 ). Malar space narrow between eye and antennal groove, much shorter than width of groove ( Fig. 28 ). Axilla and mesoscutellum with irregular longitudinal carinae, posterolateral and posterior sides smooth and shiny ( Fig. 26 ). Mesepimeron with long, distinct, almost parallel carinae ( Fig. 25 ). Hind basitarsomere subequal to length of remaining tarsomeres combined. Length of sheath slightly shorter than length of basal plate. Male unknown. Figures 23-24.

Female, labeled "[FORMOSA] Tattaka, 31.May.1965, T. Shirozu" (KU). Okutani (1966) stated "31-v-1965, Sungkang, Formosa, T. Shirozu leg.". TAIWAN: "[Taiwan], Sungkang, 2000m, Nan-tou-Hsien, 19-25.iv.1987, C. C. Lo (1 ♀, NSMT). Discussion. The two specimens examined are very similar, though the carinae on the frons and mesoscutellum of the holotype are somewhat more distinct than in the other specimen.
