Stenus persculpturatus View in CoL nov.sp. ( Figs 29 View Figs 17-29 , 57 View Figs 55-69 )
Type material: Holotype () and 7, 2 - paratypes: Taiwan: Pingtung Hsien: Peitawushan, Kuai-Ku Hut , 2325m, 21.V.1991, A. Smetana (T 88) . Paratypes: 3, 4: ibidem, 22.V.1991, idem (T 90) ; 1, 9: ibidem, 2130m, 27.IV.1992, idem (T 101) ; 6, 7: Peitawushan above Kuai-Ku hut , 2750m, 22.V.1991 (T 89).- HT and PTT in coll. Smetana (Ottawa), PTT also in cP .
Description: Apterous, black with brownish hue, elytra brownish, punctation about as in S. perpastus nov.sp.. Maxillary palpi yellowish. Antennae and legs as in S. perpastus .
Length: 2.8-3.3mm (forebody: 1.5-1.6mm).
PM of the HT: HW: 29.5; DE; 15; PW: 22; PL: 22; EW: 26.3; EL: 23; SL: 17.
Male: Metasternum flat, moderately coarsely, very densely punctate. Sternites 3-5 finer and denser punctate medially than laterally. Sternite 6 with a shallow triangular impression medially, which is very finely and very densely punctate and pubescent, sternite 7 with a broad, slightly divergent median impression, punctation and pubescence as previous, posterior margin broadly and shallowly emarginate. Sternite 8 about as in S. perpastus . Sternite 9 with long apicolateral teeth. Aedeagus (fig. 29), apical portion of median lobe triangularly narrowed, expulsion hooks separated; parameres with about 12 setae in apical third.
Female: Sternite 8 at posterior margin triangularly projection, apex rounded (about as in fig. 10). Valvifer with a long apicolateral tooth. Spermatheca (fig. 57), infundibulum short and broad.
Comparative notes: In most respects very similar to S. perpastus but the median portion of frons extending beyond the level of medial eye margins and the lateral margination of the abdominal segments even narrower, sometimes on segment 5 only traces of a thread-like line visible.- This species belongs also to the S. cephalotes- group. A reliable identification is only possible by examining the genitalia.
Etymology: Since the impressions on pronotum and elytra are very distinct, I name this new species " persculpturatus " (Lat. =very distinctly sculptured).
