Description. Male: Length 4.8–5.0 mm, width 2.3–2.4 mm. Blackish-brown, antenna, antennae, tibiae, and tarsi dark brown; elytron dark bluish- metallic. Antenna relatively short and slender, about 0.7X as long as body; ratios of length to width of antennomeres III to XI about 1.0: 1.1: 1.0: 1.0: 1.2: 1.1: 1.2: 1.3: 1.1. Pronotum strongly transverse, 2.2–2.5X wider than long, anterior margin moderately concave; sides anteriorly widened. Elytra relatively shorter, about 1.7X longer than wide. Aedeagus ( Figs 73–75 ) slender, about 3.9X longer than wide, twisted at middle, widest near apex, then abruptly narrowed, apex asymmetric, pointed, apical margin irregular; in lateral view slightly curved, abruptly narrowed near apex; tectum membranous; apico-latreral sclerites large; lateral speculae two-paired; median spicala long, about 0.8X as long as aedeagus.

Female: Length 4.3–4.7 mm, width 2.6–2.9 mm. Similar to males, but elytra wider than males, about 1.3–1.4X longer than wide. Hind wings reduced in various degrees, from slightly (0.38X as long as those of males, collected from Wushihkeng: Fig. 91 a), moderately (0.28X as long as those of males, collected from Anmashan: Fig. 91 b), to extremely reduced (0.18X as long as those males, collected from Wuchihshan: Fig. 91 c). Gonocoxae ( Fig. 76 ) connected with one wide but longitudinal sclerite, with lateral margins irregular; connection between gonocoxae and sclerite wide. Ventrite VIII ( Fig. 77 ) apically widened, surface with dense setae along apex, as well as apical margin, spiculum slender. Spermathecal receptaculum ( Fig. 78 ) as wide as pump; pump strongly curved, apex narrowly rounded; spermathecal duct short, slender, shallowly projecting into receptaculum.

Differential diagnosis. See diagnosis of Paraplotes tsoui .

Distribution. Widespread in central Taiwan (Hsinchu and Taichung counties) ( Fig. 79 ).

Etymology. Dedicated to Mrs. Su-Fang Yu for collecting a portion of the type specimens.

Notes. The specimen collected from Hassenzan (AviiM) ( Kimoto 1969) belongs to this species.
