Redescription.

Length 6.5-6.6 mm, width 2.4-2.5 mm. Body color (Fig. 5A-C ) reddish brown or yellowish brown, but antennomeres III-XI more or less darker, elytra greenish bronze. Frontoclypeus (Fig. 6A-C ) transverse and deeply excavated between eyes in males, concavity as wide as interspace between eyes; apical margin produced anterior, with clusters of hair-like setae at middle and sides, and convex at sides; with one pair of erect and slender sclerites at center, close to each other, apices rounded; with short, erect, and rounded sclerites insides at middle and sides of basal margin, margined with long hair-like setae and with longitudinal ridges at middle of basal margin. Antennae filiform in males, (Fig. 7A ), antennomeres V and VI slightly curved, length ratios of antennomeres I-XI 1.0: 0.3: 0.8: 1.0: 1.0: 1.0: 1.0: 0.9: 0.8: 0.8: 0.9, length to width ratios of antennomeres I-XI 3.7: 1.8: 3.9: 4.4: 5.0: 5.1: 5.3: 5.1: 4.8: 4.6: 5.9; similar in females (Fig. 7B ), length ratios of antennomeres I-XI 1.0: 0.4: 0.7: 0.9: 0.9: 0.9: 0.9: 0.8: 0.8: 0.7: 0.9, length to width ratios of antennomeres I-XI 3.7: 1.9: 4.0: 4.7: 4.8: 5.1: 4.9: 4.6: 4,8: 4.2: 5.3. Elytra elongate, parallel-sided, 1.9 × longer than wide; disc with dense, coarse punctures, arranged into longitudinal rows, with one indistinct longitudinal ridge between two longitudinal rows of punctures. Tarsomeres I of front legs slightly swollen in males; subparallel in females. Aedeagus (Fig. 7C-E ) slender, 7.2 × longer than wide; apex with shallow notch; tectum elongate, from apical 1/20 to basal 1/5; dorso-ventrally flattened, slightly curved in lateral view, angular at apical 1/7, straight from apex to apical 1/7; triangular sclerites small; internal sac with elongate, endophallic sclerite complex, 0.5 × as long as aedeagus, composed of three sclerites, apical piece as long as basal piece, 0.45 × long as entire sclerite; median piece shortest, 0.1 × long as entire sclerite; with one elongate, apically sclerite located near base of apical piece; with one pair of short hook-like sclerite at sides. Gonocoxae (Fig. 7G ) 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 lateral processes at basal 2/5. Ventrite VIII (Fig. 7F ) 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. 7H ) tightly joined with pump, pump slender and strongly curved; proximal spermathecal duct deeply inserted into receptacle, narrow and short.

Diagnosis.

Pseudotheopea aeneipennis (Gressitt and Kimoto) is characterized by its color pattern: reddish brown body with bluish or greenish metallic elytra (Fig. 5A-C ). The aedeagus is characterized by its broadly rounded apex, with one additional elongate dorsal sclerite near base of apical piece, and with one pair of small hook-like sclerites at sides near apex of median apical piece (Fig. 7C-E ).

Distribution.

China (Fujian, Jiangxi, Guandong, Hainan Island).
