Diagnosis.
This species belongs with species with robust body form, strongly marked pronotal summit and with a smaller number of large, chisel-shaped asperities on the antero-lateral margin of the pronotum. It would key out to couplet

Wood’s 2007
key. Depending on how the reader interprets the characters in his key, it might be incorrectly identified as

(couplet 8) which it resembles in elytral vestiture, but differs in having many fewer asperities on the anterior slope of the pronotum.
Female.
total length:
1.84 mm
(1.7–1.9), maximum width:
0.86 mm
(0.8–0.9), length of elytra:
1.15 mm
(1.1–1.2), total length / width: 2.13 elytra length / total length: 0.63, pronotal length / width: 0.80 (n = 10).
Frons convex without any elevations or impressions. Surface shining, shallowly strigose to vertex, except impunctate in narrow area from between eyes to epistoma. Vestiture of sparse setae between eyes, sparse hairs

along epistomal margin. Antenna with four segments in flagellum (plus pedicel); club oval with clearly marked sutures, narrower than width of compound eye.
Anterior margin of pronotum with two large, closely spaced teeth. Anterior slope (not including summit) with 10–12 large, chisel shaped asperities. Pronotal summit closer to posterior margin than anterior margin, sharply defined. Area posterior to summit marked by a posteriorly directed carina or additional large asperities, not reaching posterior margin of pronotum. Discal surface of pronotum with large, deep punctures; surface shining, coarsely rugose. Vestiture of erect, hair-like setae on anterior slope, with blunt scale-like setae on disc.
Striae on elytral disc weakly impressed, with punctures clearly indicated on disc and declivity, about ½ width of interstriae, becoming wider and more impressed on declivity. Interstriae on disc and declivity smooth, shining, narrowed posteriorly becoming subequal in width to striae. Erect interstrial setae scale-like, blunt, about 3× as long as wide; spaced within rows by ¾ length scale; ½ distance between rows; generally uniseriate, with a few “extra” or out-of-line setae. Strial setae small, recumbent, hair-like.
Declivity evenly convex (dorsally and laterally), without indication of impressed or elevated sutures or interstriae. Striae more impressed than on disc, punctures closely spaced. Erect interstrial setae strictly uniseriate, shorter and more closely spaced than on disc, each subtending distinct granules. Interstrial ground vestiture absent. Strial setae similar to those on disc.
Male.
Unknown.
