Description.

Male. Body dark reddish brown, darker on caudal segments, or totally black (Fig. 7). Eyes black-brown and ocelli yellowish. Antennae, upper lip, mandible, labial palpi and maxillary palpomeres brown. Legs dark reddish brown, paler on coxae and trochanter. Abdominal sternites reddish brown with the middle of the first and second sternites brown (Fig. 8).

Vertex with few punctations, exposed; face densely punctulated; ocelli round and distinct. Anterior margin of pronotum thickened, with a small mesial V-shaped indentation, a small reflexed protuberance on the each side of the excision; anterior half of pronotum depressed, with sparsely granular surface; posterior half punctured, with 2 oblique mounds armed with 2 tubercles at apex (Fig. 37). Tegmina and wings well developed, extending beyond the abdominal terminal (Fig. 7). In tegmen, the radius with 3 short or 1 relatively long posterior branches; median vein simple or branched (Figs 83-84). Radius in hind wing with apical posterior branch near the middle, which is associated with 2 branches and one of them sometimes branched, some veins fused partially; median vein branched or not; cubitus with 5-6 complete and 6-8 incomplete branches (Figs 92-93). Anterior ventral margin of front femur with 0-4 spines and a small distal spine, hind margin with a large distal spine. Abdominal tergites punctured, and the punctures denser laterally; T4-T7 with holes on the anterolateral corners which are surrounded with fine hairs, the holes on T4 small or absent; lateral margins of T7 feebly crenulate, sometimes the irregularities subobsolete and indistinct, caudal angle oblique (Fig. 38). Abdominal sternites densely punctured, hind margin with a mesial concavity (Fig. 39). Supra-anal plate densely punctate, hind margin with 8-13 subequal teeth (10 in most cases), which are broad basally, triangular, or fused together, lateral angles obtuse and about the same size as the largest tooth between them. Cercus conical, very few or no setae dorsally, ventral surface swollen, densely setose (Fig. 41). Anterior margin of subgenital plate slightly concave, lateral margins sunken (Fig. 42).

Male genitalia. Genital phallomere L1 reduced or absent (Fig. 43); L2d elongate, apically acute and forked, with a small lateral lobe (Fig. 44); R2 variably reduced and usually not hook-shaped, or absent (Fig. 45).

Female. Essentially similar to male, but larger than male and with hind margin of the seventh sternite rounded (Fig. 40).

Remarks.

Considering the Panesthia -like lateral margin on T7 and the disappearance of sclerite R2, Feng and Woo (1990) treated Panesthia concinna (Figs 7-8) as a member of the genus Panesthia . But after examining the holotype of Panesthia concinna Feng & Woo, 1990, the essentially straight lateral margin of T7 and the absence of R2 should be within the intraspecific variation of Salganea taiwanensis . Herein we treat Panesthia concinna Feng & Woo, 1990 as a synonym of Salganea taiwanensis Roth, 1979.

Distribution.

China (Jiangxi, Fujian, Guangxi, Guizhou, Guangdong, Taiwan); Japan; Vietnam.
