Kinorhynchs from sandy coastal habitats in Turkey, with the description of a new pan- Mediterranean species of Echinoderes (Cyclorhagida: Echinoderidae)

Abstract

Kinorhynchs from eight sandy, shallow water localities along the west and south coasts of Turkey were examined. The study resulted in the finding of six different species: Two species, Echinoderes gerardi and Cephalorhyncha flosculosa were known from Turkey, two species, Echinoderes riedli and Campyloderes vanhoeffeni were known from the Mediterranean, but are new to Turkey, and two species, Echinoderes sp. and E. shahmaranae sp. nov. are new to science.Echinoderes sp. resembles E. charlotteae from the Gulf of Mexico, but differs at some minor points. However, since only a single specimen was available, only diagnostic details, but no formal description, is provided. Echinoderes shahmaranae sp. nov. is described from Muğla. The species is distinguished by its unique combination of spine, tube and glandular cell type 2 distributions, as well as the presence of conspicuous, rigid, paraventral cuticular hairs. The latter character was evaluated across all echinoderid species from which information was available. It is present in only sixteen other echinoderid species, and is considered to be a character of potential phylogenetic significance. Other morphological findings include the confirmed lack of paradorsal sensory spots on segments 4 and 5, and presence of a middorsal fissure on segment 11 in C. flosculosa.

The genus Setaphyes (Kinorhyncha, Pycnophyidae) in European waters: Redescription of Setaphyes dentatus ( ) and Setaphyes kielensis ( ), including notes on morphometrics, sexually dimorphic features and reproduction of the genus

“…More recently, research on kinorhynch taxonomy in the eastern deep-sea Mediterranean and the Anatolian Peninsula to some extent balanced out the current sampling bias towards the middle and western Mediterranean (Sönmez et al, 2016;Ürkmez et al, 2016;Yıldız et al, 2016;Yamasaki et al, 2018a,b;Yamasaki and Durucan, 2018;Sørensen et al, , 2021. Regarding records of allomalorhagids in this region, four species have been found: Setaphyes dentatus (Reinhard, 1881), Setaphyes kielensis (Zelinka, 1928) Fujuriphyes ponticus (Reinhard, 1881), and Pycnophyes paraneapolitanus (Sheremetevskij, 1974).…”

En la península ibérica, el primer estudio de kinorrincos (Pardos et al, 1998) supuso la descripción de dos nuevas especies en Santoña (mar Cantábrico), Echinoderes cantabricus Pardos et al, 1998y E. hispanicus Pardos et al, 1998.…”
