PRONOTUM. Length 0.16 mm, width 0.27 mm, pubescent with a series of ± eight foveolae along the posterior margin, and further foveolae on disc becoming obliterated towards the anterior margin; lateral margins sharply angled then sinuate posteriorly to rectangular hind angles, bordered, the border extending along the posterior margin to the medial emargination ( Fig. 108B View Fig ).
ELYTRA. Length 0.43 mm, width 0.35 mm, pubescent, length of setae as pronotum, basal half foveolate.
