Taiwanoserica variegata NOMURA (Figs 1-3) Taiwanoserica variegata NOMURA, 1974: 86. Material examined - 9 ex. "Rep. of China Formosa (Taiwan) A Li Shan 17-26.6.'95 P. Moravec" (CA, CP), 4 ex. "Formosa Alishan 2400 m 17-26.6.1995 Dalihod leg." (CP). Diagnosis of male - Body length: 9.6 mm, width: 5.3 mm, elytral length: 6.7 mm. Antenna 10-segmented, club three segmented, straight, slightly longer than the remaining segments com­bined. Eyes small, ratio of diameter/ interocular width: 0.49. Pronotum widest at base, lateral margin posteriorly strongly curved, anterior two-thirds feebly curved, nearly straight and convergent anteri­orly to weakly pointed anterior angles; proepisternum basally strongly produced and reflexed, deeply grooved transversely, lateral edge of pronotum sharp. Pygidium moderately convex, finely and densely punctate, without smooth midline, with few fine, long and dense hairs. Metatibia slender and long, subparallel, width/length ratio: 1/4.4, dorsally sharply edged, with two groups of spines, basal one behind middle, apical one at three fourth of metatibial length, basally with four single hairs with punctures having a serrated margin; outside longitudinally convex, glabrous, with moderately dense, fine punctures; ventral edge with two widely separated fine hairs, basal one at one fourth, apical one at three fourth of metatibial length, inside sparsely, finely punctate, apex interiorly near tarsal articu­lation shallowly concave, nearly truncate. Tarsal segments dorsally shallowly and moderately densely punctate, ventrally with sparse short setae; metatarsal segments laterally moderately edged and with a strongly serrated ridge ventrally, dorsally not longitudinally grooved, first metatarsomere distinctly shorter than the two following segments combined and more than one-third longer than the upper tibial spur. Protibia long, bidentate, external edge at middle convexly widened, claws of ante­rior symmetrical, normally developed. Aedeagus: Figs 1-3. Notes - The original description of this species was based on a single female from Alishan. Although the type was not available for study, the specimens listed here most probably represent T. variegata. They agree closely with the original de­scription and were collected from the type locality. Taiwanoserica gracilipes NOMURA Taiwanoserica gracilipes NOMURA, 1974: 88. Material examined- 11 ex. "Taiwan: Tai Chung Co. Yun Li, near Nan Hu Da Shan alt. 2600 m. 5-9/VIII/1990 Collr. C. L. Li" (CA). Taiwanoserica elongata NOMURA Taiwanoserica elongata NOMURA, 1974: 88.
