Description. Length 6.1-6.5 mm, width 2.3-2.5 mm. Body color (Fig. 1D-F ) dark brown or blackish brown except elytra reddish brown. Antennae filiform in males, but antennomere VI-IX strongly swollen (Fig. 3A ), length ratios of antennomeres I-XI 1.0: 0.3: 0.8: 1.0: 1.0: 1.1: 1.1: 1.1: 1.0: 0.9: 1.0, length to width ratios of antennomeres I-XI 2.8: 1.3: 2.6: 3.2: 3.2: 2.7: 2.7: 2.7: 2.7: 2.8: 3.4; more slender in females (Fig. 3B ), length ratios of antennomeres I-XI 1.0: 0.3: 0.8: 0.9: 1.0: 0.9: 0.9: 0.9: 0.9: 0.8: 1.0, length to width ratios of antennomeres I-XI 3.0: 1.5: 2.9: 3.3: 3.1: 3.0: 3.3: 3.2: 3.4: 3.1: 3.5. Elytra elongate, parallel-sided, 1.9 x longer than wide; disc with dense, coarse punctures arranged into longitudinal rows, with one weak longitudinal ridge between two longitudinal rows of punctures, basally abbreviated. Tarsomeres I of front legs slightly swollen in males; subparallel in females. Aedeagus (Fig. 3C-E ) slender, 6.4 x longer than wide; sides strongly narrowed at apical 1/4 in ventral view, apical margin truncate, with shallow notch; tectum well sclerotized, basally broadened, broader than aedeagus, with hollow area at base of tectum; slightly curved in lateral view; ventral surface with deep notch from near apex, apically extending into basal 2/5; triangular sclerites small; internal sac with one median, elongate sclerite, 0.6 x as long as aedeagus, dorso-ventrally flattened, apically tapering from basal 1/3, apex acute, connected by short broad sclerite at base, disc with dense, transverse rows of hair-like setae and with one pair of elongate, longitudinal rows of stout setae at sides. Gonocoxae (Fig. 3G ) elongate, widest at apical 1/6, gonocoxae combined from basal 1/8 to apical 1/7; apices narrowly rounded, each gonocoxa with eight setae along lateral margin from apex to apical 1/6; with one pair of short lateral processes at basal 2/5. Ventrite VIII (Fig. 3F ) elongate and well sclerotized; disc with several long setae at sides and near apical margin, and with dense, short setae along apical margin; spiculum extremely slender. Receptacle of spermatheca (Fig. 3H ) strongly swollen; pump slender and strongly curved; proximal spermathecal duct deeply inserted into receptacle, narrow and long. Figure 3.

Theopea bicolor Kimoto, T. bicoloroides sp. nov., and T. mouhoti Baly are characterized by their reddish brown elytra. Theopea bicolor and T. bicoloroides sp. nov. (Fig. 1A-F ) can be easily separately from T. mouhoti by the dark brown or blackish brown head, prothorax, and scutellum, and indistinct ridges on the elytra (Fig. 1G-I ). In addition, males of T. bicolor and T. bicoloroides sp. nov. possess median elongate internal aedeagal sclerites that are covered with transverse rows of hair-like setae (Figs 2C, D ; 3C, D ). This differs from those of T. mouhoti that lack hair-like setae (Fig. 4C, D ). Theopea bicoloroides sp. nov. differs from T. bicolor by the relatively broader antennae in males (Fig. 3A ) (length to width ratios of antennomeres V-X less than 3.0 x in T. bicoloroides sp. nov. but more than 3.0 in T. bicolor (Fig. 2A )), broadly rounded apex of the ventral surface of the aedeagus (Fig. 3E ) (narrowly rounded apex of ventral surface of aedeagus in T. bicolor (Fig. 2E )), endophallic sclerite dorso-ventrally flattened and with longitudinal groove in lateral view (Fig. 3D ) (broad and lacking longitudinal groove in lateral view in T. bicolor (Fig. 2D )); and a broad notch at the apex of the gonocoxae (Fig. 3G ) (slender notch at apex of gonocoxae in T. bicolor (Fig. 2G )). Etymology. This new species is named for the similarity with Theopea bicolor Kimoto. Distribution. China: Yunnan; Laos.
