New records and within-species variability of Iberian tardigrades (Tardigrada), with comments on the species from the Echiniscus blumi-canadensis series Author Guil, Noemí text Zootaxa 2008 1757 1 30 journal article 10.5281/zenodo.181845 29cad3d2-5685-4e65-9690-3604790334f6 1175-5326 181845 Echiniscus bisetosus Heinis 1908 Specimens with the two morphotypes described for Echiniscus bisetosus ( Ramazzotti & Maucci 1983 ) were identified, among eleven specimens isolated: type C ( Table 4 ), representing 82% of specimens, and type D ( Table 4 ), representing 18%. Both types of Echiniscus bisetosus showed asymmetries. Morphotypes C and D were not mixed within the same sample. Differences were noted in the size of the cuticle sculpture pattern ( i.e. , blumi type (Ramazzotti & Maucci 1983)) . Body size ranged from 308 to 704 μm, mean 457 μm (SD 113). The species has been cited for Europe, Asia, America and Africa. In the Iberian Peninsula, it has been recorded for Portugal ( Maucci & Durante Pasa 1984 , 1985 ), but this is the first record for Spain ( Table 2 ). Echiniscus bisetosus was found at eight sampling points (Table 3), but always in MR samples.
