Body color (Fig. 1A-C ) dark brown or blackish brown except elytra reddish brown. Antennae filiform in males, but antennomeres VI-VIII slightly swollen (Fig. 2A ), length ratios of antennomeres I-XI 1.0: 0.3: 0.8: 1.1: 1.2: 1.2: 1.2: 1.1: 1.1: 1.0: 1.2, length to width ratios of antennomeres I-XI 2.8: 1.2: 2.5: 3.3: 3.6: 3.4: 3.4: 3.2: 3.5: 3.4: 4.1; filiform in females (Fig. 2B ), length ratios of antennomeres I-XI 1.0: 0.3: 0.8: 1.0: 1.0: 0.9: 0.9: 0.9: 0.9: 0.8: 0.9, length to width ratios of antennomeres I-XI 3.0: 1.4: 3.1: 3.5: 3.5: 3.2: 3.4: 3.4: 3.6: 3.4: 3.7. Elytra elongate, parallel-sided, 2.0 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. 2C-E ) slender, 6.5 x longer than wide; sides widest at middle, gradually narrowed towards basal 1/4, gradually and apically narrowed towards apical 1/5, parallel between apical 1/5 and 1/12, apex with shallow notch; tectum well sclerotized, basally broadened, as broad as aedeagus, with hollow area behind base of tectum; moderately curved in lateral view; ventral surface with deep notch from near apex, apically extending into basal opening, more approximate at apical 1/5; triangular sclerites small; internal sac with one median, elongate sclerite, 0.7 x as long as aedeagus, apically tapering from basal 1/3, apex acute, connected with 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. 2G ) elongate, widest at apical 1/6, both gonocoxae joined 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. 2F ) 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. 2H ) strongly swollen; pump slender and strongly curved; proximal spermathecal duct deeply inserted into receptacle, narrow and short. Figure 1.

Populations from Laos and southwest China were misidentified. They represent Theopea bicoloroides sp. nov. (see below). Diagnosis. 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 (Fig. 1G-I ) by the dark brown or blackish brown head, prothorax, and scutellum, and indistinct ridges in the elytra. Besides, males of T. bicolor and T. bicoloroides sp. nov. possess a median elongate sclerite internally in the aedeagus that is covered with transverse rows of hair-like setae (Figs 2C, D ; 3C, D ). This differs from those of T. mouhoti , which lacks such hair-like setae (Fig. 4C, D ). Theopea bicolor differs from T. bicoloroides sp. nov. by the relatively slender antennae (Fig. 2A ) in males (length to width ratios of antennomeres V-X more than 3.0 in T. bicolor , relatively broader antenna (Fig. 3A ), less than 3.0 in T. bicoloroides sp. nov.), the narrowly rounded apex of the ventral surface of the aedeagus (Fig. 2E ) (broadly rounded apex of aedeagus in T. bicoloroides sp. nov. (Fig. 3E )), endophallic sclerite broad and without longitudinal groove in lateral view (Fig. 2D ) (dorso-ventrally flattened and with longitudinal groove in lateral view in T. bicoloroides sp. nov. (Fig. 3D )), and slender notch at apex of gonocoxae (Fig. 2G ) (broad notch at apex of gonocoxae in T. bicoloroides sp. nov. (Fig. 3G )). Distribution. Thailand, Vietnam.
