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 View TABLE 4 ), representing 82 % of specimens, and type D ( Table 4 View 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 View TABLE 2 ). Echiniscus bisetosus   was found at eight sampling points (Table 3), but always in MR samples.
