The family Heteroceridae MacLeay, 1825 (Coleoptera, Dryopoidea) in the lberian peninsula and the Balearic Islands

Abstract

The information available on the family Heteroceridae in the lberian peninsula and the Balearic lslands is revised, based on published sources and on the study of unpublished material from the authors and museum collections. The male genitalia of the 17 studied species, eight Augyles and nine Heterocerus, is illustrated, and a brief description is included. Augyles hispidulus Kiesenwetter is recorded for the first time in the lberian peninsula, in Spain, and Heterocerus fossor Kiesenwetter for the first time in Portugal. A key to the European genus and the lberian and Balearic species of Heteroceridae is provided. Brief ecological notes and distribution maps of al1 species are also included. While the known number of species in Spain, eight Augyles and eight Heterocerus, is similar to other nearby geographical areas, the fauna of Portugal, with only seven species, and that of the Balearic Islands, with three, is considered to be still poorly known. The possible unrecorded presence of central European and north African species in Spain is discussed.
