Type material. Holotype, female: " Bolivia, La Paz, 9.4 km E. Chulumani, Apa-Apa, 2200 m, 16º 20.99' S 67º 30.30' W, 19.1.2001, R. Anderson, lower yungas litter, 2001 – 005B." Holotype in CMN.
Diagnosis. Interstriae 10 sharply elevated only to level of metacoxae, protibiae with an additional mesal socketed tooth, pronotum strongly asperate in declivious area. Distinguished from all other species by the combination of impressed striae 1, large strial punctures, granulated interstriae containing erect setae on declivity, and by the large shiny and impunctate area in the female frons.
Description female. Length 1.87 mm, 2.4 times longer than wide; colour dark reddish brown. Head. Eyes separated above by 2.5 times their width. Frons weakly impressed and flat on circular area between eyes and epistoma; surface smooth and shiny on central two-thirds, densely set punctures in a semicircle around shiny area. Vestiture consisting of medium long soft setae forming a horseshoe shaped wreath. Antennal club flattened, with two sutures marked by setae, suture 1 straight with a distinct partial septum, suture 2 procurved. Funiculus 6- segmented. Pronotum 1.1 times longer than wide, widest at base, sides parallel on basal three-fifth; anterior twofifth steeply declivious with coarse asperities that extend further backwards in lateral areas only, anterior row of asperities forming a low crenulated margin; surface finely reticulated, with punctures present on non-asperate area, each puncture spaced on average by their diameter. Vestiture consisting of fine short setae in asperate area, each seta arising from posterior base of an asperity (0–0–0). Elytra 1.4 times longer than wide, 1.4 times longer than pronotum; sides straight on basal two-thirds, broadly, almost squarely rounded behind; striae 1 strongly impressed, striae 2–3 weakly impressed, punctures large, deep, spaced by half the diameter of a puncture; interstriae as wide as striae, punctures few, very minute, frequently replaced by seta-bearing granules that increase in size on declivity. Interstriae 10 reaching level of ventrite I. Vestiture consisting of erect interstrial setae spaced by the length of a seta, more closely spaced and coarse on declivity. Legs. Procoxae separated by 0.35 times the width of a coxa. Mesocoxae separated by the width of one procoxa. Protibiae with two distinct lateral teeth of subequal length, tooth 1 slightly longer; an additional mesal socketed tooth arising close to base of tarsus. Mesotibiae armed by 6 lateral socketed teeth on distal half. Metatibiae armed by 6 lateral socketed teeth on distal third. Ventral vestiture. Setae on mesanepisternum and metanepisternum trifid.
Key. Leads to couplet 87 if one allows for a mismatch in couplet 81 (length of interstriae 10). A group of three species (S. erineophilus Wood, S. reticulatus (Wood), S. pilifrons Wood) are all quite different with much smaller elytral punctures and a totally different female frons.
Etymology. Latin, referring to the large (grosse) and deeply impressed strial punctures (punctatus).
Biology and distribution. This species is only known from the holotype locality in Bolivia.
