Stenus pertenuis View in CoL nov.sp. ( Figs 41 View Figs 30-41 , 75 View Figs 70-77 )
Type material: Holotype () and 2, 3 - paratypes: Taiwan: Kaohsiung Hsien: Creek 2 km E Tien Chih , Hwy 20, 2400m, 22.VII.1993, A. Smetana (T 161). Paratypes: 1: Kuanshan Trail above Kaunshanchi River, 2550m, 22.VII.1993, idem (T 160).- HT and PTT in coll. Smetana (Ottawa), PTT also in cP.
Description: About as in S. persubtilis nov.sp.
Length: 2.9-3.4mm (forebody: 1.5-1.6mm).
PM of the HT: HW: 31; DE: 16; PW: 22.5; PL: 23; EW: 27; EL: 25; SL: 19.5.
Male: Metasternum distinctly impressed, coarsely and densely punctate, interstices smaller than half diameter of punctures. Anterior sternites simple, sternite 7 finely and densely punctate and pubescent medially. Sternite 8 with a shallow, moderately broad apical emargination (LS: ED= 54:3). Sternite 9 with moderately long blackish apicolateral teeth. Aedeagus (fig. 41), apical portion of median lobe very broadly rounded ventrally, with a short triangular apex dorsally, expulsion hooks separated; parameres distinctly longer than median lobe, with about 8 apical setae.
Female: Sternite 8 obtusely angled triangular at posterior margin, apex rounded. Valvifer with a comparatively short apicolateral tooth. Spermatheca (fig. 75), infundibulum at least 4x as long as broad.
Median portion of frons distinctly exceeding the level of medial eye margins; elytra very uneven with deep longitudinal impressions, punctation coarser than in S. persubtilis , largest punctures as large as medial cross section of antennal segment 2; abdominal punctation dense, interstices on tergite 7 smaller than punctures.
Comparative note: This species has to be identified best by the sexual characters; see also key.
Etymology: Because of the small body I name this species " pertenuis " (Lat.= very small).
