Abstract

Augustinus tuberculatus Huang, Yoshitake & Zhang, sp. n., is described from Guizhou Province, southwestern China. The species is readily distinguishable from its congeners by the prothorax having five pairs of tubercles in addition to paired median prominences. We classify the species into a new species group, the A. tuberculatus group, based mainly on the basally convex rostrum, elytral interval 1 with a velvety black scaly patch in the basal 1/3, interval 3 with a large obtuse tubercle in the middle (with 1–3 rows of setiferous granules), the posterior margin of ventrite 2 angularly produced in the middle and the anterior and posterior margins of ventrite 4 equidistant along their entire length. A key to the species groups of Augustinus is provided.
