Rotifera from the Mediterranean Sea, with description of ten new species Author De Smet, Willem H. text Zootaxa 2015 4028 2 151 196 journal article 10.11646/zootaxa.4028.2.1 2baa825b-3af6-49ff-896e-f5cb990b4d62 1175-5326 240556 D47167E0-5C14-47F9-B4AA-9E906D13DF89 Paradicranophorus spp. Paradicranophorus sp. 1 is very similar in habitus to P. halophilus sp. nov. and occasionally co-occurring, but can not be described for lack of specimens. However, the trophi ( Fig. 27 G, H) allow for an unambiguous distinction: main differences concern shape of rami, unci, apical rami teeth and preuncinal teeth, and the absence of a stout tooth on the inner ramus margin in Paradicranophorus sp. 1. It was found in psammon from the Costa Blanca and Tyrrhenian Sea, 50 m to 1 km off shore, depth 30−40 m , water temperature 22−24 °C. Two more species with affinities to Paradicranophorus wesenberglundi Sørensen, 2001 could not be described due to the small number of specimens available. Trophi of Paradicranophorus sp. 2 ( Fig. 27 I) and 3 ( Fig. 27 J) differ from those of P. wesenberglundi (see Sørensen 2001b ) by, amongst others, shape of unci and apical rami teeth; main differences distinguishing sp. 2 and sp. 3 are the shape of the median rami opening (lenticular in sp. 2 vs . elongate drop-shaped in sp. 3), and the manubria (evenly curved in sp. 2 vs . weakly incurved distally in sp. 3). Both species were found once at the Côte d’Azur: sp. 2 in the Hyères Archipelago at 4 km off shore and depth of 45 m ; sp. 3 at Cap Bénat, 50 m from shoreline and depth of 20 m .
