CLADISTIC ANALYSIS OF 37 MEDITERRANEAN BOGIDIELLIDAE (AMPHIPODA), INCLUDING BOGIDIELLA ARISTA, NEW SPECIES, FROM TURKEY Downloaded from https://academic.oup.com/jcb/article-abstract/18/2/383/2418982 by Old Dominion University user on 30 November 2018 Stefan Koenemann, Ronald Vonk, and Frederick R. Schram ABSTRACT A new subterranean amphipod species, Bogidiella (Medigidiella) arista, found in the mesopsam- mic ground waters of southern Anatolia, Turkey, is described, together with Bogidiella (Bogidiella) calicali Karaman, the latter being recorded for the first time in the eastern Mediterranean. A cladis- tic analysis of 37 Mediterranean species of the family Bogidiellidae is performed, using 4 species from the Canary Islands as an outgroup. Alternatively, 2 cladistic software packages, PAUP 3.1.1 and HENNIG86, are employed to calculate consensus trees of minimal length. The resulting trees show more or less identical robust clades, characterizing a central, a central-eastern, and an east- ern Mediterranean group. Apart from this pattern of major geographical clusters, all species of the subgenus Medigidiella appear as a robust, monophyletic clade as well. This initial attempt to ana- lyze the phylogeny of Mediterranean bogidiellids forms a useful basis for further, extended stud- ies, using either different outgroup taxa or additional morphological data. During the spring of 1987 a major biospe- sammic species, Bogidiella (Medigidiella) leological expedition of the Dutch speleo- arista, as well as a new record of B. calicali logical society "Speleo Nederland" was car- G.
