Description.

Length 5.8-6.2 mm, width 2.1-2.4 mm. Body color (Fig. 15A-C View Figure 15 ) golden green, but mouthparts and legs yellowish brown, antennae dark brown. Frontoclypeus (Figs 16A-16B View Figure 16 ) with transverse deep groove between eyes in males, concavity 0.5 × as wide as interspace between eyes. Antennae filiform in males (Fig. 17A View Figure 17 ), antennomere I smaller than others, length ratios of antennomeres I-XI 1.0: 0.3: 1.0: 1.2: 1.2: 1.2: 1.2: 1.1: 1.1: 1.0: 1.1, length to width ratios of antennomeres I-XI 3.3: 1.2: 3.8: 4.8: 5.7: 5.5: 5.5: 5.4: 6.1: 5.6: 6.2; similar but slightly shorter in females (Fig. 17B View Figure 17 ), length ratios of antennomeres I-XI 1.0: 0.3: 0.8: 0.9: 0.9: 0.9: 0.9: 0.9: 0.9: 0.8: 0.9, length to width ratios of antennomeres I-XI 3.6: 1.7: 4.0: 4.9: 5.3: 5.3: 5.1: 5.4: 5.3: 4.9: 4.7. Elytra elongate, parallel-sided, 1.8-1.9 × longer than wide; disc with dense, coarse punctures, arranged into longitudinal rows, with one distinct longitudinal ridge between two longitudinal rows of punctures. Tarsomeres I of front legs swollen in males; subparallel in females. Aedeagus (Fig. 17C-E View Figure 17 ) extremely slender, 7.2 × longer than wide; apex with deep notch; tectum elongate, from apical 1/9 to middle; almost straight in lateral view, moderately curved near base, angular at apical 2/5; triangular sclerites elongate; internal sac with elongate, endophallic sclerite complex, 0.5 × as long as aedeagus, composed of two sclerites, apical piece as long as basal piece, one pair of dorsal sclerite hook-like, connected near base of apical piece; ventral sclerites absent. Gonocoxae (Fig. 17G View Figure 17 ) elongate, both gonocoxae fused from basal 1/4 to apical 1/4; 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. 17F View Figure 17 ) 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. 17H View Figure 17 ) strongly swollen; pump slender and strongly curved; proximal spermathecal duct shallowly inserted into receptacle, narrow and short.

Diagnosis.

Pseudotheopea hsingtzungi sp. nov. (Fig. 15A-C View Figure 15 ), P. boreri sp. nov. (Fig. 8A-C View Figure 8 ), P. clypealis (Medvedev) (Fig. 8D-F View Figure 8 ), and P. smaragdina (Gressitt and Kimoto) (Fig. 15D-F View Figure 15 ), 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 hsingtzungi sp. nov. (Fig. 15A, B View Figure 15 ) is similar to P. boreri sp. nov. (Fig. 8A, C View Figure 8 ) and P. smaragdina (Fig. 15D, E View Figure 15 ) based on the shared indistinct longitudinal ridges on the elytra (convex and distinct longitudinal ridges on the elytra in P. clypealis (Fig. 8D, F View Figure 8 )), but differs by having the concavity narrower between the eyes in males (Fig. 16A, B View Figure 16 ) (concavity wide between eyes in others (Figs 9A, B View Figure 9 ; 16C, D View Figure 16 )). Males of P. hsingtzungi sp. nov. are similar to those of P. kimotoi sp. nov. in possessing elongate triangular aedeagal sclerites (Figs 17D, E View Figure 17 ; 20E, F View Figure 20 ) but differ in the presence of one pair of long hook-like lateral sclerites of the median elongate sclerite, lacking small spines near the apex of the median elongate sclerite, and the median division (Fig. 17C, D View Figure 17 ) (lacking hook-like sclerites at sides of median elongate sclerite, with small spines near apex of median elongate sclerite, and undivided in those of P. kimotoi sp. nov. (Fig. 20D, E View Figure 20 )).
