The genus <i>Setaphyes</i> (Kinorhyncha, Pycnorhaga nom. nov.) in European waters: redescription of <i>S. dentatus</i> (Reinhard, 1881) and <i>S. kielensis</i> (Zelinka, 1928), including notes on morphometrics, sexually dimorphic features and reproduction of the genus

In the frame of a redescription of Setaphyes dentatus and S. kielensis (Kinorhyncha), an additional set of files shows images taken by SEM of Setaphyes kielensis and is available under a CC BY NC SA licence via the data publisher Museum für Naturkunde Berlin (MfN) - Leibniz Institute for Evolution and Biodiversity Science. Each file name of a SEM images indicates a continuous image number, the species name, the catalogue number, the segments photographed from which side (d, dorsal; v, ventral; le, left; ri, right side or combinations thereof), and the magnification. SEM images were taken with 2,048 x 1,536 pixels at a resolution of 72 dpi and stored with a depth of grey levels of both 8 bit (with image metadata) and 16 bit (for technical reasons of the SEM without image metadata) as uncompressed TIF files, altogether 714 files with 3.4 GB of data. Metadata of the 8 bit files include scale in micrometers, magnification as multiples of 1,000x (Mag K), voltage of the beam (EHT), working distance (WD), photo number (Photo No.), and date. Usually, noise reduction at the SEM was done in the mode “pixel averaging”, but various amounts of “line integration” (LineInteg) were applied, if charging of a specimen occurred. Last not least, best results were obtained in those cases with pixel averaging after sputtering the specimens again. Additional set of files “MfN_ZMB_CollectionVermes_SEM”. Overview and detailed SEM images of several segments from dorsal, lateral, and ventral side if available, non-types, ZMB “Vermes” 12454–12478 of Setaphyes kielensis (Kinorhyncha) from Sylt, Germany.
