850487E0836ACC65FD7FFA88C78F6F7D.taxon	description	(Figs. 1 – 3, 5 – 9) Description. Body entirely black, rounded, convex. Male (Figs. 1 – 2) body length 11 – 12 mm (n = 2). Head moderately coarsely, evenly punctate, punctures separated by distance 1.5 – 2.0 X puncture diameter on frons and genae, 1.0 – 1.5 X on clypeus. Antennomere 3 elongate, about 3 X as long as antennomere 2 and 2 X as long as antennomere 4. Pronotum narrower than elytra, transverse, widest at base, pronotal index 168.2; surface finely, sparsely, evenly punctate on disc (sparser than on head), punctures separated by distance 1.5 – 4.0 X puncture 3) S. triplehorni, female, dorsal view; 4) S. arnoldii, male, dorsal view. Scale bar = 2.0 mm. diameter, tending smaller, denser toward lateral, anterior, posterior portions; puncture interspaces smooth, dull; lateral margins finely beaded, slightly arched from posterior to anterior corners, outline with weak concavity in anterior 1 / 3; anterior margin with bead restricted to lateral 1 / 4; posterior margin without bead. Prothoracic hypomeron finely rugosegranulate; apex of prosternal process beaded, with minute, shiny median tubercle. Elytra subglobose, evenly convex, widest at middle; elytral index 83.0; surface finely, sparsely, and irregularly punctate on disc (sparser than on pronotum), smaller punctures separated by distance 3 – 5 X puncture diameter, larger punctures arranged into hardly discernible rows becoming obsolete toward apex; puncture interspaces slightly rugose, dull; lateral margins evenly arched from humeral angle to apex, visible only just posterior to humeral angle; humeral angle rectangular, humeral callosity absent. Elytral epipleura punctate and rugose as disc. Ventral sclerites of meso- and metathorax finely rugosegranulate. Abdominal ventrites with punctation as sparse as but coarser than on elytra. Legs coarsely and densely punctate. Protarsomeres 1 – 3 (Fig. 5) and mesotarsomeres 1 – 2 (Fig. 6) with dense ventral pad of reddish setae. Inner margin of apical 1 / 3 of protibiae fringed with reddish hairs. Aedeagus with apicale elongate triangular, pointed at apex, with straight sides (Figs. 7 – 9). Female (Fig. 3) body length 11 – 13 mm (n = 7). Similar to male, but larger on average. All tarsomeres without ventral pad of setae.	en	Merkl, O., Egorov, L. V.
