Contribution to the knowledge of the terrestrial isopod fauna of Lithuania

Abstract

The present survey provides records on terrestrial isopods from southern and north-western parts of Lithuania. Isopods were sampled manually by checking substrates in eight habitats (several types of forest and anthropogenic environment) between 2014 and 2016. In total, seven species were recorded. The common European species Trachelipus rathkii was noted as the most frequent isopod in all studied habitats from southern Lithuania. Porcellionides pruinosus, found in the habitat of anthropogenic activity, was recorded for the first time from Lithuania. Based on the data of the present study and previous surveys, the 14 species of terrestrial isopods are recorded in Lithuania and the current state of knowledge about Lithuanian isopod is summarised.
