Description. Habitus Fig. 2 . Length from front of head to apex of elytra 0.83 mm. Head pubescent, strongly tuberculate and with a row of prominent setae on the posterior margin. Width across eyes 0.27 mm. Antennomeres 3–11 0.37 mm long. Mentum and submentum Fig. 8 . Pronotum and scutellum pitted, strongly tuberculate Fig. 7 ; pronotum 0.23 mm long, 0.35 mm. wide, scutellum with two shallow depressions at anterior corners Fig. 6 .

Etymology. Based on the country where the insect was found.

Remarks. Very similar to E. impiger sp. n. and at first considered to be that species but distinguishable by the less shining and much denser and more tuberculate head and pronotum, and by the absence of a visible spermathecal duct.
