Stenus perversor View in CoL nov.sp. ( Figs 32 View Figs 30-41 , 69 View Figs 55-69 )
Type material: Holotype () and 34, 23 - paratypes: Taiwan: Nantou Hsien: Houhanshan , 3175m, 15.V.1991, A. Smetana (T 59). – HT and PTT in coll. Smetana (Ottawa), PTT also in cN, cT and in cP.
Description: About as in S. persubtilis nov.sp.
Length: 2.5-3.0mm (forebody: 1.4-1.5mm).
PM of the HT: HW: 28; DE: 15; PW: 20.5; PL: 20; EW: 25; EL: 21.5; SL: 16.5.
Male: Metasternum shallowly impressed, moderately coarsely, densely punctate, interstices smaller than half diameter of punctures. Anterior sternite simple, sternite 7 finer and denser punctate and pubescent medially than laterally. Sternite 8 with a moderately broad, shallow apical emargination (LS: ED= 51:2). Sternite 9 with comparatively short, blackish apicolateral teeth. Aedeagus (fig. 32), median lobe narrowly rounded apically, expulsion clasp strong; parameres nearly as long as median lobe, with about 6 apical setae.
Female: Sternite 8 obtusely angled triangular at posterior margin, apex narrowly rounded. Valvifer with a short apicolateral tooth. Spoermatheca (fig. 69) with an oval infundibulum.
Median portion of frons strongly elevated, in most specimens narrowly impunctate; pronotum and elytra in most (not in all) specimens with deep impressions, punctation coarser than in S. persubtilis and more distinctly coalescent, diameter of elytra punctures slightly larger than apical cross section of antennal segment 2; punctation of tergite 7 dense, interstices mostly smaller than punctures.
Comparative note: This new species may be distinguished from most of its close relatives by the oval infundibulum, from all by the aedeagus.
Etymology: Since this species makes the identification of very close species more difficult I name it " perversor " (Lat.= the spoiler).
