Smetana (Ottawa), PTT also in cP .
Description: About as in S. persubtilis nov.sp.
Length: 2.8-3.2mm (forebody: 1.5-1.6mm).
PM of the HT: HW: 30; DE: 16; PW: 23.5; PL: 22.5; EW: 28; EL: 24; SL: 19.
Male. Metasternum broadly impressed, coarsely and densely punctate posteriorly, very sparsely punctate anteriorly,. Anterior sternites more finely and less densely punctate medially than laterally, sternite 6 very shallowly impressed in posterior middle, finely and sparsely punctate, sternite 7 shallowed along middle, finely and densely punctate and pubescent. Sternite 8 with a moderately broad, shallow apical emargination (LS: ED= 49:3). Sternite 9 with comparatively short blackish apicolateral teeth. Aedeagus (fig. 42), in outline resembling that of S. perodiosus , but the apical portion of median lobe much longer, the expulsion hooks of different shape; parameres distinctly longer than median lobe, with 7-8 apical setae.
Female: Sternite 8 and Valvifer as in S. perodiosus . Spermatheca (fig. 68), infundibulum comparatively short and broad.
Median portion of frons distinctly exceeding the level of medial eye margins, narrowly impunctate; pronotum with deep impressions, median impression impunctate; elytra distinctly uneven, coarsely and densely punctate, diameter of punctures at least as large as apical cross section of antennal segment 2; abdomen densely punctate, but interstices often larger than punctures.
Comparative notes: This new species may be distinguished from many of its relatives by the strongly elevated median portion of frons, by the short apicolateral teeth of sternum 9, by the coarse elytral punctation, the length and the sexual characters.
Etymology: Because of the strongly punctate elytra I name this new species " perpunctus " (Lat.= strongly punctate).
