Stenus kuanmontis View in CoL nov.sp. ( Figs 78, 81 View Figs 78-82 )

Type material: Holotype (): Taiwan: Kaohsien Hsien : Kuanshan trail at Kuanshanchi River, 2400m, 20.IV.1992, A. Smetana (T 94): in coll. Smetana (Ottawa).

Description: Brachypterous, black, moderately shiny, forebody moderately coarsely (frons) to coarsely (pronotum, elytra), very densely punctate, abdomen moderately coarsely (anteriorly) to moderately finely (posteriorly), densely punctate; pubescence short, recumbent. Segment 1 and base of segment 2 of maxillary palpi reddish yellow, remainder brown. Antennae dark brown. Legs dark reddish brown. Clypeus and labrum blackish, moderately densely pubescent.

Length: [2.3-] 2.8mm (forebody: 1.4mm).

PM of the HT: HW: 26; DE: 16.5; PW: 20.8; PL: 20; EW: 26; EL: 24.5; SL: 19.

Male: Unknown.

Female: Sternite 8 (fig. 78). Valvifer serrate apicolaterally. Spermatheca (fig. 81), infundibulum short.

In many respects similar to S. houhanmontis nov.sp., but the head less broad, the actual middle of frons less densely punctate (interstices about as large as punctures). Elytra subquadrate, shoulders rectangular, nearly all punctures distinctly delimited, tergite 7 with a narrow but distinct membranous fringe apically, abdominal punctation slightly coarser and slightly denser, interstices on tergite 7 nealy as large as punctures. The whole insect has very faint microsculpture and is therefore distinctly more shiny than the compared species.

Comparative notes: This new species is also closely retaled to S. rugipennis SHARP and S. suspectatus PUTHZ , from which it may be easily distinguished by the much smaller elytra, the pointed sternite 8 of the female and the spermatheca. From S. hseuhmontis nov.sp. it may be distinguished by the subquadrate elytra, the apical membranous fringe of tergite 7, denser pronotal punctation, less elevated median portion of frons and by the shape of sternite 8 of the female and the spermatheca with a shorter infundibulum.

Etymology: The name is derived from the type locality.
