Head width 0.5mm, deeply withdrawn into prothorax; distance between compound eyes slightly less than width of compound eye; compound eyes reaching pleurosternal suture. Antennal length 2.5mm, scape longer than wide, pedicel shorter than scape, subquadrate; antennomeres III-X subequal in length, with rami originating from base, each slightly longer than previous antennomere; antennomere XI apically rounded; antennomeres heavily setose. Pronotal width at base 1.5mm, pronotal length 0.75 mm, densely punctured, setae directed medio-posteriorly.Mesoscutellar length 0.15 mm. Elytra length 2.25 mm, width 1.7 mm, with apparently 11 striae on each side; distance between punctures equal to diameter of one puncture; setae along margin of elytra directed laterally, setae covering elytra directed medio-posteriorly.
