Paraplotes tahsiangi Lee , sp. nov.

( Figs 33–38 , 85 )

Type locality. Nontou county, Meifeng (ffiR), 24°105’N, 121°10’E, 2100 m.

Type material (n= 59). Holotype ♂ ( TARI): Nantou: Meifeng (ffiR), 30.V.2011, leg. M.-H. Tsou“. Paratypes: 29♂♂, 18♀♀ ( TARI), same data as holotype; 2♂♂, same locality, 11.VI. –8.VII.2003, leg. C. S. Lin & W. T. Yang ( NMNS); 2♂♂, same locality, 5.V. –11.VI.2003, leg. C. S. Lin & W. T. Yang ( NMNS); 2♂♂, same locality, 17.VI.2010, leg. C.-F. Lee ( TARI); 3♂♂, same locality, 19.VI.2010, leg. C.-F. Lee ( TARI); 3♂♂, same locality, 12.VI.2014, leg. C.-F. Lee ( TARI); 2♂♂, Tsuifeng (ϓR), 2300m, 25–27.VI.1981, leg. K. S. Lin & W. S. Tang ( TARI).

Description. Male: Length 4.7–5.1 mm, width 2.6–2.8 mm. Black but antennae and legs dark brown or blackish brown; elytra dark bluish metallic. Antenna relatively long, about 0.8X as long as body; ratios of length to width of antennomeres III to XI about 1.0: 1.0: 1.0: 1.1: 1.0: 1.0: 1.3: 1.2: 1.6. Pronotum strongly transverse, about 2.3X wider than long, anterior margin slightly concave, lateral margins crounded. Elytra long, about 1.5X longer than wide. Aedeagus ( Figs 33–35 ) wide, about 3.8X longer than wide, parallel, abruptly narrowed near apex, apex pointed; in lateral view strongly curved, extremely narrowed toward apex, apex narrowly rounded; tectum sclerotized; apico-lateral sclerites large; lateral speculate two-paired; median specula long, about 0.95X as long as aedeagus.

Female: Length 4.5–5.0 mm, width 3.1–3.2 mm. Similar to males but elytra much wider, about 1.2–1.3X longer than wide. Hind wings ( Fig. 85 ) reduced in various degrees, from moderately (0.28X as long as those of males) ( Fig. 85 a) to extremely (0.16 as long as those of males) ( Fig. 85 c). Gonocoxae ( Fig. 36 ) connected with a longitudinal sclerite, apically pointed, irregularly margined; connection between gonocoxae and sclerite slender. Ventrite VIII ( Fig. 37 ) apically widened, surface with dense setae along apex, as well as apical margin, spiculum slender. Spermathecal receptaculum ( Fig. 38 ) narrower than pump; pump strongly curved, apex narrowly rounded; spermathecal duct short, slender, shallowly projecting into receptaculum.

Differential diagnosis. Paraplotes tahsiangi sp. nov. is similar to P. y a oi with the wide aedeagus (<4.0X longer then wide) and large apico-lateral sclerites ( Figs 33–35 , 67–69 ), but P. tahsiangi has the apex of the aedeagus pointed ( Figs 33–35 ) (subtruncate apex in P. y ao i).

Distribution. Type specimens were collected on the road from Meifeng (ffiR) to Tsuifeng (ϓR) ( Fig. 80 ).

Etymology. Dedicated to Mr. Ta-Hsiang Lee for assisting in collecting.
