Redescription.

Length 5.7-6.7 mm, width 2.2-2.4 mm. Body color (Fig. 15D-F ) golden green, but antennae, mouth parts, and legs yellowish brown, five or six apical antennomeres darker. Frontoclypeus (Fig. 16C, D ) transverse and deeply excavated between eyes in males, concavity as wide as interspace between eyes; with one erect process at center, apically tapering; one pair of membranous areas surrounding erect process, mesally connected; with several erect hair-like setae at sides of anterior margin. Antennae filiform in males, but relatively broader than those of female (Fig. 22A ), antennomeres III-IX slightly curved, length ratios of antennomeres I-XI 1.0: 0.3: 0.9: 1.1: 1.0: 0.9: 0.9: 0.8: 0.8: 0.8: 1.0, length to width ratios of antennomeres I-XI 3.8: 1.3: 3.4: 4.1: 4.5: 4.2: 4.1: 4.1: 4.3: 4.6: 6.4; filiform in females (Fig. 22B ), length ratios of antennomeres I-XI 1.0: 0.3: 0.6: 1.0: 1.0: 0.9: 0.9: 0.8: 0.8: 0.7: 0.9, length to width ratios of antennomeres I-XI 3.4: 1.7: 3.1: 4.7: 4.6: 5.0: 4.8: 4.9: 4.9: 4.6: 5.3. Elytra elongate, parallel-sided, 1.8-1.9 × longer than wide; disc with dense, coarse punctures, arranged into longitudinal rows, with distinct longitudinal ridge between two longitudinal rows of punctures. Tarsomeres I of front legs swollen in males; subparallel in females. Aedeagus (Fig. 22C-E ) extremely slender, 9.4 × longer than wide; apex with shallow notch, both apices not equal in length; tectum elongate, from apical 1/12 to basal 2/5; almost straight in lateral view, apically curved, angular at apical 1/4; triangular sclerites small; internal sac with elongate, endophallic sclerite complex, 0.6 × as long as aedeagus, composed of two sclerites, apical piece as long as basal piece, two dorsal sclerites unequal in length; ventral sclerites present. Gonocoxae (Fig. 22G ) elongate, both gonocoxae fused from basal 1/4 to apical 1/3; apices convergent and 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. 22F ) longitudinal 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. 22H ) strongly swollen; pump slender and strongly curved; proximal spermathecal duct deeply inserted into receptacle, narrow and short.

Diagnosis.

Pseudotheopea smaragdina (Gressitt and Kimoto) (Fig. 15D-F ), P. boreri sp. nov. (Fig. 8A-C ), P. clypealis (Medvedev) (Fig. 8D-F ), and P. hsingtzungi sp. nov. (Fig. 15A-C ), 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 smaragdina (Fig. 15D, E ) is similar to P. hsingtzungi sp. nov. (Fig. 15A, B ) and P. boreri sp. nov. (Fig. 8A , 8C ) in sharing the indistinct longitudinal ridges on the elytra (convex and distinct longitudinal ridges on the elytra in males P. clypealis ), but it differs by having a wider concavity between the eyes bearing one erect process in males (Fig. 16C, D ) (concavity wide between eyes without erect processes in males of P. boreri sp. nov. (Fig. 9A, B ); concavity narrowed between eyes and without erect processes in males of P. hsingtungi sp. nov. (Fig. 16A, B )). Males of P. smaragdina are similar to those of P. clypealis with one additional elongate aedeagal sclerite and one pair of small lateral hook-like sclerites inside the internal sac (Figs 11C, D ; 22D, E ). They differ in having asymmetrical apices of the aedeagus and a relatively shorter apical piece (as long as basal piece) of the median elongate sclerite (Fig. 22C-E ) (symmetric apices and relatively longer apical piece, 4.0 × as long as basal piece in P. clypealis (Fig. 11C-E )).

Distribution.

China (Hainan Island, Fujian, Hong Kong).
