Derivation of name. From uni (Latin= one) plus vitta (Latin= stripe) for the medial longitudinal stripe on the pronotum.

Diagnosis. This species is in group 6 ( Uhmann 1937). It can be distinguished from all other species in group 6 by antennomeres VI­VII being transverse, by antennomeres VIII­ X being subequal in length, by the arcuate lateral margins of the pronotum, and by the medial, longitudinal vitta on the pronotum.

Description. Yellowish­brown; eyes dark; pronotum with medial longitudinal black vitta; elytral with diffuse aeneous markings. Head: medial sulcus present; vertex alutaceous; small tooth present between antennal bases; frons angulate in middle. Antenna: antennomere I subglobose; II­V cylindrical, III longest; VI­VII transverse; VIII­X cylindrical, subequal in length; XI elongate, acutely pointed at apex. Pronotum: convex; lateral margin arcuate, constricted behind anterior margin; each anterior angle with strong tooth; surface coarsely, shallowly punctate; faint medial longitudinal sulcus and faint basal impression both present; pronotal length 1.3 mm; pronotal width 1.6 mm. Scutellum: quadrate; alutaceous. Elytron: slightly expanded to apex; lateral margin smooth; apical margin dentate; exterior apical angle with strong backwardly directed tooth; humerus prominent, angulate; with 10 rows of punctures plus short scutellar row; interspace 4 costate for entire length, 6 costate at base and apex, 8 costate at apex; elytral length 6.2 mm; elytral width 3.0 mm. Venter: yellowish­brown except for mesosternum black laterally. Total length: 7.8 mm.

Variation. Specimens vary in pronotal length from 1.3­1.4 mm, in pronotal width from 1.4­1.7 mm, in elytral length from 6.0­ 6.3 mm, in elytral width from 2.9­3.3 mm, and in total length from 7.1­8.0 mm. The color and sculpture is very similar to that of the holotype.
