Lee, Chi-Feng, 2015, The genus Paraplotes Laboissière, 1933 in Taiwan, a speciose group with brachelytrous females (Coleoptera: Chrysomelidae: Galerucinae), Zootaxa 3904 (2), pp. 223-248 : 239

Paraplotes tsuenensis Lee , sp. nov.

( Figs 61–66 , 89 )

Type locality. Hualien county, Tsuen (sg), 24°11’N, 121°23’E, 2100 m.

Type material (n= 15). Holotype ♂: Hualien: Tsuen (sg), 12.VII.2014, leg. M.-H. Tsou. Paratypes: 8♂♂, 6♀♀, same data as holotype.

Description. Male: Length 4.9–5.0 mm, width 2.4–2.5 mm. Blackish brown; elytra bluish- or purplishmetallic. Antenna relatively long, about 0.8X as long as body; but slender, ratios of length to width of antennomeres III to XI about 1.0: 1.1: 1.1: 1.0: 1.2: 1.0: 1.2: 1.1: 1.5. Pronotum strongly transverse, 2.5X wider than long, anterior margin slightly concave, lateral margin rounded. Elytra long, about 1.6X longer than wide. Aedeagus ( Figs 61–63 ) relative wider about 3.3X longer than wide, twisted at middle, widest at apex, then abruptly narrowed, apical margin subtruncate; in lateral view moderately curved, apex subequal to base in width; tectum membranous; apico-lateral sclerites large; lateral spiculae two-paired; median specula long, about 0.8X as long as aedeagus.

Female: Length 4.3–4.6 mm, width 2.6–3.0 mm. Similar to males, but elytra relatively wider than males, about 1.2–1.4X longer than wide. Hind wings ( Fig. 89 ) extremely reduced, about 0.20–0.23X as long as those of males. Gonocoxae ( Fig. 64 ) connected with one longitudinal sclerite, narrowest near base, basal margin slightly concave; connection between gonocoxae and sclerite wide. Ventrite VIII ( Fig. 65 ) apically widened, surface with dense setae along apex, as well as apical margin, spiculum slender. Spermathecal receptaculum ( Fig. 66 ) as wide as pump; pump strongly curved, apex widely rounded; spermathecal duct short, stout, shallowly projecting into receptaculum.

Distribution. Only known from the type locality ( Fig. 80 ).

Etymology. Named after the type locality.
