Description.

Length 5.6-6.6 mm, width 2.0-2.6 mm. Body color (Fig. 8A-C ) golden green, but legs yellowish brown but apices of tibiae and tarsi darker; mouth parts and antennae dark brown. Frontoclypeus (Fig. 9A, B ) transverse and deeply excavated between eyes in males, concavity as wide as interspace between eyes, margined with long hair-like setae except along basal margin; with dense, long hair-like setae at center. Antennae filiform in males, (Fig. 10A ), relatively broader than females, antennomeres V and VI slightly curved, length ratios of antennomeres I-XI 1.0: 0.3: 0.9: 1.2: 1.1: 1.1: 1.1: 1.0: 1.0: 0.9: 1.1, length to width ratios of antennomeres I-XI 3.2: 1.3: 3.2: 4.1: 4.4: 4.5: 4.9: 5.1: 5.2: 5.0: 5.8; filiform in females (Fig. 10B ), length ratios of antennomeres I-XI 1.0: 0.3: 0.7: 0.9: 0.9: 0.8: 0.8: 0.8: 0.8: 0.8: 0.9, length to width ratios of antennomeres I-XI 3.8: 2.1: 3.7: 4.8: 4.9: 4.4: 4.7: 5.1: 5.3: 4.9: 6.6. Elytra elongate, parallel-sided, 1.8-2.0 × longer than wide; disc with dense, coarse punctures, arranged into longitudinal rows, with one indistinct longitudinal ridge between two longitudinal rows of punctures; with distinct convex area behind scutellum in males. Tarsomeres I of front legs swollen in males; subparallel in females. Aedeagus (Fig. 10C-E ) extremely slender, 7.7 × longer than wide; apex with shallow notch, both apices equal in length; tectum elongate from apical 1/10 to basal 2/5; moderately curved in lateral view, angular at apical 1/4, straight from apex to apical 1/4; triangular sclerites elongate; internal sac with elongate, endophallic sclerite complex, 0.4 × as long as aedeagus, composed of two sclerites, apical piece (0.6 ×) much shorter than basal piece. Gonocoxae (Fig. 10G ) 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, some setae extremely short; lateral processes reduced. Ventrite VIII (Fig. 10F ) 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. 10H ) tightly joined with pump, pump slender and strongly curved; proximal spermathecal duct deeply inserted into receptacle, narrow and short.

Diagnosis.

Pseudotheopea boreri sp. nov. (Fig. 8A-C ), P. clypealis (Medvedev) (Fig. 8D-F ), 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 boreri sp. nov. (Fig. 8A ) is similar to P. hsingtzungi sp. nov. (Fig. 15A ) and P. smaragdina (Fig. 15D ) by sharing the indistinct longitudinal ridges on the elytra (convex and distinct longitudinal ridges on the elytra in P. clypealis (Fig. 8D )), but differs by the presence of convex area surrounding scutellum and with reduced longitudinal ridges on the elytra in males (Fig. 8A ) (without convex area surrounding scutellum on the elytra in those of others (Figs 8D , 15A, D )) and concavity wide between eyes and without erect processes in males (Fig. 9A, B ) (concavity wide between eyes with one erect process in those of P. smaragdina (Fig. 16C, D ); concavity narrowed between eyes and without erect processes in those of P. hsingtzungi sp. nov. (Fig. 16A, B )). In males, the internal aedeagal sac of P. boreri sp. nov. lacks additional sclerites except the median elongate sclerite (Fig. 10C, D ). This structure is shared with males of P. gressitti sp. nov. (Fig. 14C, D ), and P. costata (Allard), Pseudotheopea boreri sp. nov. males differ from both species in possessing a dorso-ventrally flattened aedeagus with a sclerotized ventral surface (Fig. 7C-E ) (wide aedeagus with membranous ventral surface in P. gressitti sp. nov. (Fig. 14C-E )).

Etymology.

This new species is dedicated to Matthias Borer (Curator, NHMB), who encouraged the first author to focus his research on leaf beetles.

Distribution.

India.
