Stenus shibataianus View in CoL nov.sp. ( Figs 35 View Figs 26-45 , 101 View Figs 89-107 , 110, 112, 120 View Figs 108-121 )
T y p e m a t e r i a l: Holotype and 1, 1 - paratypes: TAIWAN: Kaohsiung Hsien: near Tengchih , 13.VIII.1978, leg. Y. SHIBATA . Paratypes: 1: Nantou Hsien: Lushanwenchuan , 28.V.1980, leg. H. MAKIHARA ; 1: Chiai Hsien: Fenchihu , 4.VI.1971, leg. M. NISHIKAWA. HT and PTT in coll. Y. SHIBATA, PTT also in coll. Naomi and in cP .
D e s c r i p t i o n: Macropterous, black with a faint brownish hue, each elytron with a round reddish spot in posterior middle (fig. 35), moderately shiny, coarsely and very densely punctate; pubescence short, recumbent. Antennae yellowish brown, club infuscate. Maxillary palpi yellowish red, segment 3 infuscate. Paraglossa oval. Legs reddish brown. Clypeus black, labrum blackish brown, moderately densely pubescent.
Length: 4.3-5.0 mm) (forebody: 2.1-2.2 mm).
PM of the HT: HW: 37.5; DE: 19; PW: 28.5; PL: 30; EW: 37.5; EL: 38; SL: 29.
M a l e: Legs simple. Metasternum shallowly impressed, coarsely and densely punctate, smooth interstices smaller than half diameter of punctures (fig. 101). Anterior sternites simple, sternite 6 slightly shallowed and finely punctate posteromedially, sternite 7 with a shallow finely and densely punctate median impression. Sternite 8 apically with a small rounded notch about one tenth as long as the sternite. Sternite 9 pointed apicolaterally. Tergite 10 broadly rounded apically. Aedeagus (fig. 110), apical portion of median lobe obtuse-angled narrowed, expulsion hooks large, internal sac with a weakly sclerotized falgelliform tube, parameres slightly longer than median lobe, with 3+4 apical setae.
F e m a l e: Sternite 8 rounded apically. Valvifer acute apicolaterally (fig. 120). Tergite 10 rounded apically. Spermatheca (fig. 112), spermathecal collum long-oval, spermathecal duct weakly sclerotized (incomplete in the type specimen?).
In many respects similar to S. electristigma , but the head narrower. Elytra broader, size and position of the elytral spots different. Abdominal punctuation about same as in S. electristigma , but the punctuation denser: on tergite 4 interstices are distinctly smaller than diameter of punctures, punctation of tergite 7 much finer than in the compared species, punctures distinctly smaller than eye facets near dorsal eye margins, interstices much larger than punctures, punctuation of tergite 10 fine and sparse.
C o m p a r a t i v e n o t e: Also this new species belongs to the S. indubius -group as is shown by the spermatheca. For identification amongst the Taiwanese species see key.
E t y m o l o g y: This new species is dedicated to its collector, Mr. Y. SHIBATA.
