Stenus perplicatus nov.sp. ( Figs 34-36 , 61 )

Type material: Holotype () and 1 - paratype: Taiwan: Nantou Hsien: Meifeng , 2130m, 4.V.1998, A. Smetana (T 199) . Paratypes: 2 ibidem, 3.V.1991, idem (T 61) ; 3, 1: ibidem, 10.VII.1993, idem (T 146) ; 7, 9: ibidem, 2100m, 26.X.2000, H.

Smetana (Ottawa), PTT also in cN, cT and in cP .

Description: About as in S. persubtilis nov.sp.

Length: 2.5-3.3mm (forebody: 1.4-1.5mm).

PM of the HT: HW: 29.5; DE: 15; PW: 22; PL: 23; EW: 26.5; EL: 23.5; SL: 17.5.

Male: Ventral characters as in S. persubtili s. Aedeagus (fig. 34), apical portion of median lobe triangularly narrowed (figs 35, 36), apex narrowly rounded, expulsion hooks connected medially; parameres with 7-10 apical setae.

Female: Sternite 8 and valvifer as in the compared species. Spermatheca (fig. 61), infundibulum comparatively short and broad.

In all respects very similar to S. persubtilis except in the genitalia.

Comparative notes: This new species may be distinguished from its relatives by the genitalia.

Etymology: Since this species is extremely similar to S. persubtilis I name it " perplicatus " (Lat.= very intricate).
