Description.

Length 6.6-7.5 mm, width 2.6-3.2 mm. Body color (Fig. 18A-D View Figure 18 ) metallic blue or purple, but antennae and legs yellowish brown, mouth parts dark brown. Frontoclypeus (Fig. 19A, B View Figure 19 ) transverse and weakly excavated between eyes in males, semi-circular, the annular concavity 0.8 × as wide as interspace between eyes, with cluster of long setae near middle of anterior margin, some shorter setae scattered along anterior margin. Antennae filiform in males (Fig. 20A View Figure 20 ), but relatively broader than those of females (Fig. 15A View Figure 15 ), length ratios of antennomeres I-XI 1.0: 0.3: 0.9: 1.1: 1.2: 1.0: 1.1: 1.0: 1.0: 0.9: 1.1, length to width ratios of antennomeres I-XI 3.3: 1.6: 3.4: 4.4: 4.9: 4.2: 4.8: 4.5: 4.7: 4.8: 4.7; filiform in females (Fig. 20B View Figure 20 ), length ratios of antennomeres I-XI 1.0: 0.3: 0.7: 0.9: 1.0: 0.9: 0.9: 0.8: 0.8: 0.8: 0.9, length to width ratios of antennomeres I-XI 4.2: 2.2: 4.1: 5.1: 5.6: 5.4: 5.7: 5.1: 5.5: 5.2: 6.2. Elytra elongate, parallel-sided, 1.7-1.9 × longer than wide; disc with dense, coarse punctures, arranged into longitudinal rows, with one distinct and convex longitudinal ridge between two longitudinal rows of punctures, with convex area behind scutellum, ridges reduced at convex area. Tarsomeres I of front legs strongly swollen in males; subparallel in females. Aedeagus (Fig. 20D-F View Figure 20 ) slender, 8.4 × longer than wide; apex with shallow notch; tectum elongate, from apical 1/13 to basal 1/3; almost straight in lateral view, angular at apical 2/5, moderately curved near base; triangular sclerites elongate; internal sac covered with stout teeth, with elongate endophallic sclerite, 0.5 × as long as aedeagus, some small, stout teeth at apical 1/8 to 2/5. Gonocoxae (Fig. 20H View Figure 20 ) elongate, both gonocoxae fused from basal 1/4 to apical 1/5; apices convergent and narrowly rounded, each gonocoxa with eight setae along lateral margin from apex to apical 1/6, four much longer than others; lateral processes reduced. Ventrite VIII (Fig. 20G View Figure 20 ) 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. 20I View Figure 20 ) strongly swollen; pump slender and strongly curved; proximal spermathecal duct deeply inserted into receptacle, narrow and short.

Variation.

One male collected from Dalat has a smaller body (5.3 mm long, 2.2 mm wide) and the convex area on the elytra is indistinct and with longitudinal ridges (Fig. 20D View Figure 20 ), antennomeres IV-VI are curved (VII-XI lost, Fig. 20C View Figure 20 ), and the frontoclypeus lacks a concavity.

Diagnosis.

Pseudotheopea kimotoi sp. nov. is similar to P. clypealis (Medvedev) and P. leehsuehae sp. nov. based on the convex and distinct longitudinal ridges on the elytra but differs in having all longitudinal ridges convex and distinct (Fig. 18A, C, D View Figure 18 ) (intertwined with convex distinct ridges and weak indistinct ones in others (Figs 8D, F View Figure 8 ; 18F, H View Figure 18 ), with a convex area surrounding the scutellum and longitudinal ridges reduced on the convex area in males (Fig. 18A View Figure 18 ) (without convex area surrounding scutellum in those of others (Figs 8D View Figure 8 , 18F View Figure 18 )) and the shallow concavity between it in males (Fig. 19A, B View Figure 19 ) (deep concavity in others (Figs 9C, D View Figure 9 ; 13C, D View Figure 13 )). Males of P. kimotoi sp. nov. (Fig. 20E, F View Figure 20 ) are similar to those of P. hsingtzungi sp. nov. (Fig. 17D, E View Figure 17 ) in possessing elongate triangular aedeagal sclerites but differ in the absence of lateral sclerites attached to the median elongate sclerite, with small spines near apex of median elongate sclerite, which is undivided (Fig. 20D, E View Figure 20 ) (with one pair of hook-like sclerites at sides of median elongate sclerite, without small spines near apex of median elongate sclerite, and divided at middle in those of P. hsingtzungi sp. nov. Fig. 17C, D View Figure 17 )).
