Abstract
A new copepod species Speleophriopsis mljetensis collected from an anchialine cave Bjejajka on Mljet Island Croatia is described The prosome of the new species is 5segmented the urosome has five somites in females and six in males the genital doublesomite is symmetrical and is longer than wide the caudal rami are symmetrical with seta I well developed the antennules of both sexes are 27segmented and symmetrical the antennal exopod is 7segmented the maxillule possesses 15 armature elements on the praecoxal arthrite and the proximal basal endite has three slender setae and one stout clawlike seta the fifth legs are symmetrical 4segmented and uniramous and the distal segment is elongate and armed with seven and six elements in males and females respectively Speleophriopsis mljetensis is comparated with similar species S balearicus and S canariensis The new species is mainly distinguished by the armature of the genital operculum the fifth legs of both sexes maxilliped distal segment armature and total length of both sexes This is the second report of a speleophriid copepod otherwise thought to be a Tethyan relict from an Adriatic anchialine cave In the Bjejajka Cave the salinity varied between 15 at the surface to 39 psu at the bottom and the temperature ranged between 142 and 166 °C It might be assumed that it colonised Bjejajka anchialine cave from its natural deepsea habitat However the distributions of speleophriids in the Mediterranean are difficult to explain therefore this finding is of particular importance contributing to our knowledge of the global biogeography of these Tethyan relictsI would like to thank Branko Jalžić from the Croatian Natural History Museum Zagreb and members of the Croatian Biospeleological Society in Zagreb for collecting the material on which this work was based Many thanks go to drsc Nikola Tvrtković for his supported investigations of anchialine caves along the eastern Adriatic coast I would also like to thank Geoff A Boxshall and the anonymous reviewers for their suggestions on the improvement of this paper
