Habitat and general distribution.

Pterostichus anthracinus is a West Palaearctic species ( Arndt et al. 2011). It prefers habitats that combine warm and wet conditions (Kolesnikov and Karyaman 2019) like floodplains and forest stream banks ( Lindroth 1992).

Comments.

Pterostichus anthracinus is known from the Greek mainland, Peloponnese and the Aegean ( von Oertzen 1886; Apfelbeck 1904; Arndt et al. 2011). To our knowledge, this is the first time P. anthracinus has been reported from Crete. It was only recorded from one locality (Agya Lake). Unfortunately, we observed intense human intervention (construction of various artificial structures mainly for recreational activities) near the sampling site. Given that Agya Lake is an artificial lake, it is uncertain whether P. anthracinus is a relatively novel species of the Cretan Carabid fauna. More research regarding its distribution in the island is needed.
