Redescription.

Length 5.9-6.8 mm, width 2.3-2.6 mm. Body color (Figs 8D-F , 11 ) golden green, but antennae, mouth parts, and legs yellowish brown, two or three apical antennomeres darker. Frontoclypeus (Fig. 9C, D ) transverse and deeply excavated between eyes in males, concavity 0.5 × as wide as interspace between eyes, anteriorly narrowed, margined with long hair-like setae and with one erect process at center, margined with hair-like setae; baso-lateral angles covered by rounded membranous sclerites. Antennae filiform in males, (Fig. 11A ), antennomeres III-IX slightly curved, length ratios of antennomeres I-XI 1.0: 0.3: 0.7: 0.8: 0.8: 0.8: 0.8: 0.7: 0.7: 0.6: 0.7, length to width ratios of antennomeres I-XI 3.6: 2.0: 3.2: 3.8: 3.8: 3.8: 4.2: 4.3: 3.9: 4.4: 5.3; filiform in females (Fig. 11B ), similar to males, length ratios of antennomeres I-XI 1.0: 0.3: 0.6: 0.8: 0.8: 0.7: 0.7: 0.7: 0.6: 0.6: 0.7, length to width ratios of antennomeres I-XI 4.0: 2.0: 3.3: 4.8: 4.9: 4.4: 4.8: 4.7: 4.3: 3.9: 4.5. Elytra elongate, parallel-sided, 1.8 × longer than wide; disc with dense, coarse punctures, arranged into longitudinal rows, with one longitudinal ridge between two longitudinal rows of punctures with convex, with distinct and indistinct ridges intertwined. Tarsomeres I of front legs swollen in males; subparallel in females. Aedeagus (Fig. 11C-E ) extremely slender, 10.0 × longer than wide; apex with shallow notch, both apices equal in length; tectum elongate, from apical 1/10 to basal 2/5; almost straight but moderately curved at basal 1/5 in lateral view, apically curved, angular at apical 1/3; triangular sclerites small; internal sac with elongate, endophallic sclerite complex, 0.6 × as long as aedeagus, composed of two sclerites, apical piece (4.0 ×) much longer than basal piece, one dorsal sclerite slender, 0.3 × as long as endophallic sclerite; ventral sclerites absent but one additional pair of hook-like sclerites present. Gonocoxae (Fig. 11G ) elongate, both gonocoxae fused from basal 1/3 to apical 1/4; apices convergent and narrowly rounded, each gonocoxa with seven setae along lateral margin from apex to apical 1/6; with one pair of short lateral processes at basal 2/5. Ventrite VIII (Fig. 11F ) 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. 11H ) tightly joined with pump, pump slender and strongly curved; proximal spermathecal duct deeply inserted into receptacle, narrow and short.

Diagnosis.

Pseudotheopea clypealis (Medvedev) (Fig. 8D-F ), P. boreri sp. nov. (Fig. 8A-C ), P. hsingtzungi sp. nov. (Fig. 15A-C ), and P. smaragdina (Gressitt and Kimoto) (Fig. 15D-F ), are characterized by their golden green coloration. They can be identified based on their distribution: P. boreri sp. nov. from India, P. clypealis from Vietnam, P. hsingtzungi sp. nov. from Laos, and P. smaragdina from China. Pseudotheopea clypealis can be separated from the others by the convex and distinct longitudinal ridges on the elytra (Fig. 8D, F ) (indistinct longitudinal ridges on the elytra in others (Figs 8A, C ; 15A, B, D, E ), and the narrower anterior concavity between eyes (Fig. 9C, D ) (broadly rounded anterior margin of concavity between eyes in others (Figs 9A, B ; 16A-D ). Males of P. clypealis are similar to those of P. smaragdina in possessing one additional elongate dorsal sclerite and one pair of small lateral hook-like sclerites inside the internal sac (Figs 11C, D ; 22D, E ). They differ in possessing symmetrical aedeagal apices and a relatively longer apical piece (4.0 × longer than basal piece, Fig. 11C, D ) (asymmetrical apices and relatively shorter apical piece, as long as basal piece in P. smaragdina (Fig. 22D, E )).
