Redescription of Ephemeroporus barroisi (Richard, 1894) (Cladocera, Chydoridae) on the Basis of Material from Mediterranean Anatolia (Turkey)
Abstract
Ephemeroporus barroisi, accepted as nomen dubium though there are many reports to date, is redescribed on the basis of partenogenetic female, eppihipial female and male collected from Mediterranean Anatolia, Turkey. It is decided that Anaolian specimens represent the species described by Richard. On the basis of nineteen diagnostic characters that were widely used in the description and diagnosis of the species in the previous studies Ephemeroporus barroisi is most similar first to E. epiaphantoii and next to E. margalefi. It is concluded that the barroisi group can not be defined by a single outomorphy, but by the character combination of the presence of four labral teeth and that of the denticles on the posterior angle of valves. Finally, an account on the distribution of species from the barroisi group is presented and it has been postulated that the species of the barroisi group may have been derived from an ancestral stock that were present in the old Mediterranean
