Specimens vary in pronotal width from 1.7 2.0 mm, in elytral length from 6.0 6.1 mm, and in total length from 7.77.9 mm. The color and sculpture is very similar to that of the holotype.Published as part of Staines, C.

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 7.1 8.0 mm. The color and sculpture is very similar to that of the holotype.Published as part of Staines, C.
