Type material: Holotype () and 17, 19 - paratypes: Taiwan: Nantou Hsien: Yushan National Park , 1.8 km W Pai-Yun Hut, 3375m, 17.V.1991, A. Smetana (T 85) . Paratypes: 11, 9: ibidem, 2 km W Pai-Yun Hut , 3350m, 16.V.1991, idem (T 84) ; 1, 1: Yushan National Park, Mun-Li Clif , 2700m, 13.V.1991, idem (T 79).- HT and PTT in coll. Smetana (Ottawa), PTT also in cN, cT and in cP .
Description: About as in S. persubtilis nov.sp.
Length: 2.5-3.5mm (forebody: 1.4-1.6mm).
PM of the HT: HW: 29; DE: 15; PW: 21; PL: 21; EW: 26.5; EL: 23; SL: 17.
Male: Metasternum shallowly impressed, moderately coarsely and moderately densely punctate, interstices often as large as half diameter of punctures. Anterior sternites simple, sternite 7 finer and denser punctate and pubescent posteromedially. Sternite 8 with a very shallow apical emargination (LS: ED= 50:2). Sternite 9 with comparatively short apicolateral teeth (fig. 12). Aedeagus (fig. 38), apical portion triangularly narrowed, apex acute, expulsion hooks connected medially; parameres slightly longer than median lobe, with about 8-9 apical setae.
Female: Sternite 8 at posterior margin slightly projecting, apex moderately broadly rounded. Valvifer with a comparatively short apicolateral tooth. Spermatheca (fig. 67), infundibulum more than 3x as long as broad.
About as S. persubtilis , but the elytra with deep longitudinal impressions in lateral half and near suture; median portion of frons distinctly exceeding the level of medial eye margins; longitudinal impression of pronotum deep, broadly impunctate and deeply reticulate, dull; abdominal punctation throughout very dense.
Comparative note: This new species resembles many similar species with deep elytral impressions, from which it should be distinguished by examining the sexual characters.
Etymology: Because of its great similarity with other species of the group and the difficulty to identify this species I name it " perodiosus " (Lat.= very odious).
