Paraplotes tatakaensis Lee , sp. nov.

( Figs 51–54 , 87 )

Type locality. Nantou county, Tungfu (№A), near Tatachia (ffiffi3), 23°32’N, 120°53’E, 2100 m.

Type material (n= 22). Holotype ♂: Nantou: Tungfu (№A), 8.V.2011, leg. M.-H. Tsou“. Paratypes: 19♂♂, 1♀, same data as holotype, but of which 7♂♂ collected by T.-H. Lee, 7♂♂, 1♀ collected by C.-F. Lee; 1♂, Tatachia (ffiffi3), 20.VII.2009, leg. C.-F. Lee.

Description. Male: Length 4.5–4.7 mm, width 2.3–2.5 mm. Blackish brown or black; sometimes antennae, tibiae, and tarsi dark brown, elytra dark bluish 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: 0.9: 0.9: 0.9: 1.1: 1.2: 0.9: 1.3. Pronotum strongly transverse, about 2.3–2.5X wider than long, anterior margin slightly concave, lateral margins rounded. Elytra long, about 1.5–1.6X longer than wide. Aedeagus ( Figs 51–53 ) slender, about 5.3X longer than wide, abruptly narrowed near apex, apex pointed; in lateral view strongly curved, gradually narrowed toward apex, apex narrowly rounded; tectum sclerotized; apico-lateral sclerites small; lateral spiculae two-paired; median specula long, about 0.9X as long as aedeagus.

Female: Length 4.6–4.7 mm, width 3.2–3.3 mm. Similar to males but elytra much wider, about 1.2X longer than wide. Hind wings ( Fig. 87 ) extremely reduced, about 0.19X as long as those of males, apically reduced. Gonocoxae ( Fig. 54 ) combined with one wide but longitudinal sclerite, with margin extremely irregular; connection between gonocoxae and sclerite extremely slender. Ventrite VIII and spermatheca lost.

Differential diagnosis. See diagnosis of Paraplotes taiwana .

Distribution. Type specimens were collected on the road from Tungfu (№A) to Tatachia (ffiffi3) ( Fig. 80 ).

Etymology. Name after one of the type localities.
