description: Key to the species of S. tolutarius species group
1. Elytra (Figs 23, 31) with apex not visible in dorsal view, hidden by slope overhanging apex; pronotum with punctures of two different sizes, with unevenly scattered coarse and conspicuously smaller and fine punctures.......................... 2
- Elytra (Fig. 9) with apex visible in dorsal view; pronotum with punctures of equal size, in some species weakly variable in size but never distinctly small............................................................................... 3
2. Rostrum 1.61–1.67× as wide as long; pronotum 1.03–1.06× as wide as long; elytra (Fig. 31) laterally flat, slope overhanging apex, evenly descending downwards; tarsi with segment 2 1.1–1.2× as wide as long.............. S. tolutarius Schoenherr
- Rostrum 1.85× as wide as long; pronotum 1.11× as wide as long; elytra (Fig. 23) with slope overhanging apex, rounded and then perpendicularly falling downwards; tarsi with segment 2 1.4× as wide as long............... S. marocanus Hoffmann
3. Pronotum shiny, with very fine and sparse punctures; distance between two nearest pronotal punctures greater than diameter of a puncture; elytra at most 1.68× as long as wide, with semierect setae on disc, and with finely punctate striae; distance between elytral punctures greater than a puncture diameter; interstriae distinctly wider than striae; funicle segments in females wider than long................................................................................ S. muelleri Lona
- Pronotum matt, densely punctate; distance between two nearest pronotal punctures smaller than diameter of a puncture; elytra at least 1.81× as long as wide, with semi-appressed setae on disc, and with coarsely punctate striae; distance between elytral punctures shorter than their diameter; interstriae weakly wider or equally wide as striae; funicle segments in females longer than wide or as long as wide (except for S. leonhardi)......................................................... 4
4. Epifrons (Fig. 16) wide, with distinctly concave sides, posteriorly significantly enlarged, at base only slightly narrower than space between anterior margins of eyes; funicle segments 3–7 in females wider than long; pronotum in female wider than long.................................................................................... S. leonhardi Wagner
- Epifrons (Fig. 19) slender, at basal half subparallel-sided, at base significantly narrower than space between anterior margins of eyes; funicle segments 3–7 in females isodiametric or longer than wide; pronotum in female isodiametric or longer than wide................................................................................................ 5
5. Femora ventraly with small but distinct tooth (Fig. 2); rostrum with slightly concave sides and slightly laterally projecting pterygiae; striae and interstriae with equally large punctures; interstriae weakly wider than striae; female sternite VIII (Fig. 3) with isodiametric plate, narrowly sclerotised along anterior margin and with large fenestra; spermatheca (Fig. 4) with ramus and nodulus perpendicular................................................................. S. benedikti sp. n.
- Femora adentate (Fig. 8); rostrum with straight sides, without laterally projecting pterygiae; punctures in striae distinctly larger than those on interstriae; striae and interstriae equally wide; plate of female sternite VIII (Figs 10, 20) wider than long, with apical half uniformly sclerotized and lacking fenestra; spermatheca (Fig. 12) with ramus and nodulus divergent, V-shaped.. 6
