Description: About as in
S. persubtilis
nov.sp.
Length:
2.7-3.2mm
(forebody:
1.4-1.6mm
).
PM of the HT: HW: 30; DE; 16; PW: 22; PL: 22; EW: 26.5; EL: 23.5; SL: 18.
Male: Metasternum shallowly impressed, moderately coarsely and moderately densely punctate, interstices mostly larger than half diameter of punctures. Anterior sternites simple, sternite 7 finer and denser punctate and pubescent medially than laterally. Sternite 8 with a broad and shallow apical emargination (LS: ED= 51:3). Sternite 9 with comparatively short, blackish apicolateral teeth. Aedeagus (fig. 33), apex of median lobe pointed, expulsion clasp broad; parameres as long as median lobe, with 8-9 apical setae.
Female: Sternite 8 at posterior margin feebly and roundly projecting. Valvifer with a short apicolateral tooth. Spermatheca (fig. 72), infundibulum slender, about 3x as long as broad.
Median portion of frons distinctly exceeding the level of medial eye margins; pronotum and elytra with deep impressions; abdominal punctation dense, interstices on tergite 7 distinctly smaller than punctures.
Comparative notes: This new species may be distinguished from
S. perversor
nov.sp.
, which has been found in about the same area, by the shape of the spermatheca with a relatively slender infundibulum, and by the aedeagus with a more pointed median lobe, from all other close relatives also by the sexual characters.
Etymology: Since this species has no exceptional characters I name it "
permodestus
" (Lat.= very modest).
