(6) Cypris pubera O.F. Müller, 1776

Daday (1892, 1900) described the following five varieties of Cypris pubera , mainly in relation to the presence/absence and development of posteroventral marginal spines of the right valve: anacantha (absence of spines), monacantha (one single spine), diacantha (two spines), triacantha (three spines) and polyacantha (more than three spines). We consider these varieties – which were not retained in any of the subsequent faunistic synopses (e.g., G.W. Müller 1912; Klie 1938 a; Farkas 1958; Henderson 1990; Meisch 2000) – to express the morphological variability of the species and they are therefore listed here as synonyms of the main form. Daday (1900) does not mention the variety triaculeata of C. pubera , which he had described eight years earlier ( Daday 1892). The latter variety was raised to species rank by Fuhrmann & Pietrzeniuk (1990), mainly based on the difference in the posteroventral spines of the right valve. However, we here consider triarticulata to rank within the variability range of Cypris pubera , a variation that is indeed to be expected in a species that reproduces almost entirely parthenogenetically (males of C. pubera are so far only known from one site in Turkey; Schäfer 1952). Cypris triaculeata sensu Fuhrmann & Pietrzeniuk 1990 is therefore listed as a synonym of Cypris pubera .
