dc.description.abstractSix of the eight species of the genus Setaphyes have been described from Europe. In the present contribution, the European Setaphyes species are revised and two of them, S. dentatus (Reinhard, 1881) and S. kielensis (Zelinka, 1928), are redescribed following the current approaches of Kinorhyncha taxonomy. For this purpose, material from 17 localities throughout the Atlantic Ocean and the Mediterranean and Black Seas was investigated. The redescriptions of two of the most common pycnophyid species in Europe include detailed information on intraspecific variation among populations. Setaphyes dentatus is characterized by the presence of middorsal el-evations on segments 2-6, and middorsal processes on segments 1, 7-9, unpaired paradorsal setae on segments 2-9; laterodorsal setae on segments 3, 5 and 7; ventromedial setae on segments 4-5, 7-8 in males and 3-5, 7-9 in females; anterior cuticular, reticulate ridges on the tergal plate of segment 1 and conspicuous patch of later-odorsal and ventrolateral longitudinal, cuticular ridges on segment 10. Setaphyes kielensis is characterized by middorsal elevations on segments 1-9; paired paradorsal setae on segments 2-9 (unpaired on segment 8); lat-erodorsal setae on segments 2-9; ventromedial setae on segments 3-9. Furthermore, morphometric features of the European Setaphyes are analysed. Specifically, the morphometric analyses revealed sex-specific variability in the LTS/TL proportion, with females of all the European species of Setaphyes showing smaller LTS/TL. Thus, the LTS/TL ratio unveils a conspicuous sexual dimorphism in the genus.

dc.description.sponsorshipThe present study was partially funded by the project Fauna Iberica XII: Escalidoforos de la Peninsula Iberica y Baleares (PGC-2018 095851- B -C62) of the Ministerio de Ciencia, Innovacion y Universidades (MICINN) of Spain. Samples from Tuerkiye were obtained through the framework of the project ANEMONE Assessing the vulnerability of the Black Sea marine ecosystem to human pressures, funded by the EU under ENI CBC Joint Operational Programme Black Sea Basin 2014-2020, grant contract 83530. We kindly acknowledge the project coordinator Dr. Laura Boicenco and the team leader of Sinop University, Dr. Levent Bat for the samplings on the Southern Black Sea coast. For help with sampling in Germany B.N. is grateful to Dr Hiroshi Yamasaki, Kyushu University, Fukuoka, Japan, and to Birgit Hussel, Alfred-Wegener -Institute, Wadden Sea Station List/Sylt, Germany.
