Redescription.

Length 4.1-5.0 mm, width 2.5-3.3 mm. General color dark brown or blackish-brown (Fig. 3 View Figure 3 ); each antennomere paler at base; legs yellowish-brown, but apices of femora and bases of tibiae blackish-brown. Antennae (Fig. 4A View Figure 4 ) filiform in males, ratios of lengths of antennomeres I to XI 1.0: 0.5: 0.6: 0.6: 0.6: 0.6: 0.6: 0.6: 0.6: 0.7: 0.9; ratios of length to width from antennomeres I to XI 3.3: 2.3: 2.5: 2.7: 2.7: 2.9: 2.9: 3.0: 2.9: 3.1: 3.6; similar in females, ratios of lengths of antennomeres I to XI (Fig. 4B View Figure 4 ) 1.0: 0.5: 0.6: 0.7: 0.6: 0.6: 0.6: 0.6: 0.6: 0.6: 0.8; ratios of length to width from antennomeres I to XI 3.2: 2.2: 2.7: 2.9: 3.2: 3.1: 3.0: 2.8: 3.0: 3.0: 3.6. Procoxal cavities widely open. Elytra 1.10-1.20 times longer than wide; disc with dense, confused, coarse punctures and longitudinal smooth patches; apices tapering in males but widely rounded in females. Tarsomeres I of front legs not modified in either sex. Penis (Fig. 4C, D View Figure 4 ) wide, about 6.3 times longer than wide; parallel sided but slightly curved in lateral view, apex narrowly rounded, base slightly sinuate; tectum broad from apical 1/10 to middle, apex truncate; ventral surface with large opening. Endophallic spiculae complex with median endophallic spiculae slender, apically bifurcate, and straight in lateral view, with one pair of small sclerites near basal third. Gonocoxae (Fig. 4E, F View Figure 4 ) short; apex of each gonocoxa widely rounded, with five to 13 long setae along apical margin, strongly narrowed in basal 1/3, with extreme wide base. Ventrite VIII (Fig. 4G View Figure 4 ) short and well sclerotized, with several short setae along apical margin, spiculum short. Spermathecal receptaculum (Fig. 4H View Figure 4 ) slightly swollen; pump extremely slender and curved; sclerotized spermathecal duct short.

Diagnosis.

Adults of Taiwanoshaira chujoi (Kimoto) comb. nov. are similar to those of T. tsoui sp. nov. based on the following shared characters: elytra smooth and lacking longitudinal ridges (Figs 3A, C-D View Figure 3 , 6D, F View Figure 6 ) (presence of the longitudinal ridges on elytra in T. taipingshanensis sp. nov. (Fig. 6A, C View Figure 6 )), widely open procoxal cavities (Fig. 2B View Figure 2 ) (almost closed procoxal cavities (Fig. 2A View Figure 2 ) in T. taipingshanensis sp. nov.), yellowish-brown legs with dark apices of femora and bases of tibiae (Figs 3 View Figure 3 , 6D-F View Figure 6 ) (entirely black legs in T. taipingshanensis sp. nov. (Fig. 6A-C View Figure 6 )), uniform protarsi I in both sexes (sexually dimorphic protarsi I in T. taipingshanensis sp. nov.), tapering elytral apices in only males (Fig. 3 View Figure 3 ) (tapering elytral apices of both sexes (Fig. 6A-C View Figure 6 ) in T. taipingshanensis sp. nov.). Taiwanoshaira chujoi comb. nov. differs from T. tsoui sp. nov. in possessing black or blackish elytra (Fig. 3 View Figure 3 ) with denser punctures in contrast to the black or blackish-brown elytra with yellowish-brown suture and margin (Fig. 6D-F View Figure 6 ) and sparser punctures of T. tsoui sp. nov. In addition, most genitalic characters of this species are diagnostic, including the slightly curved penis (Fig. 4C, D View Figure 4 ) (moderately curved (Fig. 8C, D View Figure 8 ) in T. tsoui sp. nov.), wider base of gonocoxae (Fig. 4E-F View Figure 4 ) (narrower base of gonocoxae (Fig. 8M, N View Figure 8 ) in T. tsoui sp. nov.), and longer, slender spermathecal pump (Fig. 4H View Figure 4 ) (shorter, wider spermathecal pump (Fig. 8Q View Figure 8 ) in T. tsoui sp. nov.).
