Description. Male: Length 4.6–4.8 mm, width 2.7–2.8 mm. Brown or blackish brown; thoracic and abdominal ventrites blackish brown or black; elytra bluish- or purplish- metallic. Antenna relatively short, about 0.7X as long as body; but slender, ratios of length to width of antennomeres III to XI about 1.0: 1.0: 1.0: 1.0: 1.1: 1.0: 1.0: 1.1: 1.5. Pronotum strongly transverse, 2.1X wider than long, anterior margin slightly concave, lateral margin rounded. Elytra long, about 1.4X longer than wide. Aedeagus ( Figs 55–57 ) relative wider about 3.1X longer than wide, twisted at middle, widest near apex, then abruptly narrowed; apex concave at middle of apical margin, apical margin slightly irregular; in lateral view moderately curved, gradually narrowed toward apex; tectum membranous; apico-lateral sclerites large; lateral spiculae two-paired; median specula long, about 0.8X as long as aedeagus.

Female:Length 4.3–4.8 mm, width 2.6–3.0 mm. Similar to males, but elytra relatively wider than males, about 1.3–1.4X longer than wide. Hind wings ( Fig. 88 ) extremely reduced, about 0.14–0.20X as long as those of males, apically reduced. Gonocoxae ( Fig. 58 ) connected with one transverse sclerite, widest near base, basal margin slightly concave; connection between gonocoxae and sclerite extremely wide. Ventrite VIII ( Fig. 59 ) apically and extremely widened, surface with dense setae along apex, as well as apical margin, spiculum slender. Spermathecal receptaculum ( Fig. 60 ) as wide as pump; pump strongly curved, apex widely rounded; spermathecal duct short, stout, shallowly projecting into receptaculum.

Differential diagnosis. Similar to Paraplotes meihuai ( Figs 21–26 ). Paraplotes tsoui , P. tsuenensis and P. yuae are characterized by their asymmetric and twisted aedeagi ( Figs 55–57 , 61–63 , 73–75 ). P. ts oui and P. y u ae are separated from P. tsuenensis by the irregular and tapering apical margins of aedeagi ( Figs 55–57 , 73–75 ). P. tsoui differs from P. y ua e by its wider aedeagus in dorsal and lateral views, and the concave apex ( Figs 55–57 ).

Distribution. Widespread in northern Taiwan (Taipei city, Taoyuan, Ilan, and Taichung counties) ( Fig. 79 ).

Etymology. Dedicated to Mr. Mei-Hua Tsou for collecting a portion of type specimens.
