Acupalpus lusitanicus Dejean, 1829: 469 .

The specimen here recognized as holotype is a male bearing the labels “ex-Museo Chaudoir”, “ lusitanicus m. in Lusitania”, “Schüppel” and “ Holotype of Acupalpus lusitanicus Dejean, 1829, J. Serrano vidit.” .

The recognition of this specimen as the holotype of the species is based on the statement of Dejean (1829): Je ne possède qu’un individu mâle de cet insecte, qui m’a été envoyé pai’ M. Schuppel, comme venant du Portugal .

The characteristics of the holotype slightly differ from those described in Serrano & Ortuño (2001), in that it has a pronotum side less rounded and the posterior angle is more marked, not so rounded. Keys to the species see Fuente (1927), Antoine (1959) and Serrano & Ortuño (2001).

It is distributed in the Iberian Peninsula, the Maghreb and southern Italy (Jaeger & Kataev, 2017).
