Derivation of name. From sanguis (Latin= blood) for the bright red dorsal coloration.

Diagnosis. This species belongs in group 4b ( Uhmann 1937) and is most similar to S. minuta Staines. It can be distinguished by the bright red color, by antennomeres II­X being cylindrical, and by the 12 rows of punctures on each elytron.

Description. Antennae, head, scutellum, and legs, except base of femora, black; pronotum bright red with medial black vitta and black lateral margins; elytra bright red; pro­, meso­, and metasterna yellowish medially, black laterally; abdominal sterna black. Head: medial sulcus present; row of punctures present along inner margin of each eye; vertex alutaceous; triangular projection present between antennal bases; frons smooth, yellowish. Antenna: antennomere I subglobose, shorter than II; II­V cylindrical, III as long as I & II combined, IV­V decreasing in length; VI cylindrical, length of V; VII­X cylindrical, subequal in length, each longer than VI; XI elongate, rounded at apex; I­VII with scattered setae; VIII­XI setose. Pronotum: convex; lateral margin sinuate, distinctly angulate just behind middle; each anterior angle with rounded tooth; posterior angle acute; densely punctate except near anterior margin; punctures on disc smaller; medial callus present; pronotal length 0.9 mm; pronotal width 1.0 mm. Scutellum: quadrate; micropunctate.

Elytron: lateral margin sinuate, smooth; exterior apical angle rounded; apical margin laminate, smooth; apices emarginate; sutural angle with distinct tooth; humerus slightly produced, rounded; 12 rows of punctures; interspaces 2, 4, & 8 costate, 8 most pronounced, 2 & 4 more pronounced apically; elytral length 4.2 mm; elytral width 1.6 mm. Venter: pro­ and mesosterna punctate; metasternum with few punctures medially at base; 5 visible abdominal sterna. Total length: 5.5 mm.

Variation. Specimens vary in pronotal length from 0.9­1.0 mm, in pronotal width from 1.0­ 1.1 mm, in elytral length from 4.1­4.6 mm, in elytral width from 1.4­1.7 mm, and in total length from 5.3­5.9 mm. The color and sculpture is very similar to that of the holotype.
