Redescription.

Length 5.6-5.9 mm, width 2.3-2.5 mm. Body color (Fig. 18D, E View Figure 18 ) black, antennae and legs pale yellow, two or three apical antennomeres, and one or two apical tarsomeres darker. Antennae filiform in male, antennomeres VII-XI slightly curved (Fig. 24A View Figure 24 ), length ratios of antennomeres I-XI 1.0: 0.3: 0.8: 1.2: 1.3: 1.1: 1.2: 1.1: 1.0: 0.9: 1.0, length to width ratios of antennomeres I-XI 3.4: 1.6: 3.5: 4.9: 5.2: 4.8: 4.9: 4.8: 4.4: 4.1: 4.4; filiform and shorter in females (Fig. 24B View Figure 24 ), length ratios of antennomeres I-XI 1.0: 0.3: 0.8: 0.9: 1.0: 0.9: 1.0: 1.0: 0.9: 0.8: 1.0, length to width ratios of antennomeres I-XI 3.6: 1.8: 3.8: 4.2: 4.7: 4.3: 5.0: 4.9: 4.4: 4.3: 5.5. Elytra elongate, parallel-sided, 1.6-1.7 × longer than wide; disc with dense, coarse punctures, arranged into longitudinal rows, with one indistinct longitudinal ridge between two longitudinal rows of punctures, with dense, short setae along ridges. Tarsomeres I of front legs slightly swollen in males; subparallel in females. Aedeagus (Fig. 24C-E View Figure 24 ) slender, 7.8 × longer than wide; apex with shallow, broad notch, with a pair of small processes forming circular cavity; tectum short, from apex to apical 1/3, as broad as aedeagus; almost straight in lateral view, strongly curved at base, moderately curved near apex; triangular sclerites absent; internal sac with elongate, endophallic sclerite complex, 0.4 × as long as aedeagus, undivided; with one ventral sclerite elongate, 0.85 × as long as elongate, endophallic sclerite complex, with lateral expansion at apical 1/3, composed of dense short setae, apically tapering. Gonocoxae (Fig. 24G View Figure 24 ) elongate, both gonocoxae fused from basal 1/3 to near apex; 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, recurved and combined, extending to apex. Ventrite VIII (Fig. 24F View Figure 24 ) 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. 24H View Figure 24 ) strongly swollen; pump slender and strongly curved; proximal spermathecal duct deeply inserted into receptacle, broad and short, strongly curved near base.

Diagnosis.

Pseudotheopea nigrita (Medvedev) is easily recognized by its characteristic black color and dense setae on the elytra. In addition, a number of autapomorphic characters among genitalic structures are diagnostic, including the circular notch of the aedeagal apex; broad tectum, characteristic shape of the ventral sclerite, the recurved and combined lateral processes of the gonocoxae, and strongly curved proximal spermathecal duct of spermatheca.

Remarks.

Most setae are missing from the elytra of the holotype (Fig. 18E View Figure 18 ), but these setae are dense on the elytra (Fig. 18F View Figure 18 ) of other specimens examined.

Distribution.

Thailand.
