Description.

Length 5.3-6.7 mm, width 2.3-2.8 mm. Body color (Fig. 5F-H ) metallic blue or purple, antennae and legs yellowish brown, mouthparts dark brown. Frontoclypeus (Fig. 19C, D ) transversely deeply excavated between eyes, concavity 0.8 × as wide as interspace between eyes; with one longitudinal ridge from middle of anterior margin to basal 1/3, with hair-like setae along lateral margins of longitudinal ridge; one pair of membranous areas near sides of longitudinal ridge and anterior margin; with one small rounded process at center of labrum, disc with several hair-like setae. Antennae filiform in males, but relatively broader than those of females (Fig. 23A ), 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: 1.0, length to width ratios of antennomeres I-XI 4.2: 1.2: 3.6: 3.9: 4.2: 4.2: 4.2: 4.9: 4.6: 4.2: 5.8; filiform in females (Fig. 23B ), length ratios of antennomeres I-XI 1.0: 0.3: 0.7: 0.9: 0.9: 0.8: 0.9: 0.8: 0.8: 0.7: 0.8, length to width ratios of antennomeres I-XI 3.6: 1.7: 3.9: 4.9: 5.3: 5.0: 5.3: 5.0: 4.8: 4.9: 5.5. Elytra elongate, parallel-sided, 1.7 × 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 slightly swollen in males; subparallel in females. Aedeagus (Fig. 23C-E ) extremely slender, 9.7 × longer than wide; apex with shallow incision; tectum short, from apical 1/12 to 1/4; almost straight in lateral view, slightly curved at base; triangular sclerites small; internal sac with elongate, endophallic sclerite complex, 0.6 × as long as aedeagus, composed of two sclerites, apical piece (0.7 ×) much shorter than basal piece, dorsal sclerite well developed, 0.5 × as long as apical piece. Gonocoxae (Fig. 23G ) elongate, both goncoxae 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. 23F ) 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. 23H ) strongly swollen; pump slender and strongly curved; proximal spermathecal duct deeply inserted into receptacle, narrow and short.

Diagnosis.

Pseudotheopea sufangae sp. nov. (Fig. 5F-H ) is similar to P. azurea (Gressitt and Kimoto) (Fig. 5D, E ) based on distinct but not convex ridges on the elytra. It differs by possessing a broad concavity between the eye with a median ridge (Fig. 19C, D ) (narrow concavity between eyes and without ridge in P. azurea (Fig. 6A )). Males of P. sufangae sp. nov. are characterized by its incised aedeagal apex (with notch in other species), and presence of only one additional elongate dorsal sclerite near the base of the apical piece of the aedeagus (Fig. 23C-E ). Females of P. sufangae sp. nov. are similar to those of the sympatric species, P. sauteri . Both lack sexually dimorphic characters but female P. sufangae differ in having the frons elevated above the clypeus (Fig. 19E ) (frons as same height as clypeus in females of P. sauteri (Fig. 19F )).

Etymology.

The new species is dedicated to Mrs. Su-Fang Yu, who is a member of the Taiwan Chrysomelid Research Team (TCRT) for her contribution to the diversity of leaf beetles.

Distribution.

Taiwan.
