Abstract

Ancyronyx jaechi sp. n. from Kegalle District, Sabaragamuwa Province, Sri Lanka is described. The new species is rec-ognized by a unique combination of the elytral colour pattern, as well as the shape and size of the male sternite IX, theaedeagus, the female ovipositor, and the secondary sexual characters. An updated world checklist of the species of Ancy-ronyx Erichson, 1847 including authority clarification for A. montanus Freitag & Balke, 2011 is provided. The distributional area of the genus and its diagnostic characters are discussed. The habitats of Ancyronyx species are briefly discussed.
