Catálogo de los coleópteros acuáticos de la ZEC Complejo Ons-O Grove, Pontevedra (Galicia)

Abstract

The Ons-O Grove Complex is classified as a ZEC zone, it is located in the extreme northwest of the province of Pontevedra (Galicia). It is a coastal wetland of great biological interest formed by a great variety of aquatic environments. A provisional catalog of aquatic beetles is proposed for this wetland consisting of 76 taxa from 11 different families. The data presented have been obtained from different sources, 19 species based on bibliographic citations already published and 57 species (22 Adephaga / 35 Polyphaga) collected within the ZEC Ons-O Grove. The knowledge of the aquatic beetles of the autonomous community of Galicia is expanded with the contribution of 5 new species for this community Dryops gracilis (Karsch, 1881), Helophorus (Rhopalhelophorus) obscurus Mulsant, 1844, Helophorus (Rhopalhelophorus) asturiensis Kuwert, 1885, Helophorus (Helophorus) grandis Illiguer, 1798 and Cercyon (Cercyon) sternalis (Sharp, 1918). This last species is listed for the first time for the iberian peninsula. For the province of Pontevedra there are 11 new species and for the study area 36.
