Diphascon (Diphascon) patanei Binda & Pilato, 1971

Material examined: Two specimens (body length 127.2 and 204.5 µm) collected from a moss sample at Parque Biológico (Avintes, Vila Nova de Gaia) were mounted in Hoyer’s medium.

Distribution: The species was recorded from various localities of the Mediterranean region ( Italy, Turkey) and from North America.

After this study, 63 limno-terrestrial tardigrade species are recorded for Portugal, including 10 described as new species to science ( Table 5 ). However, some records needs to be confirmed. Eventual mis-identifications, already stressed by Maucci & Durante-Pasa (1984c), could have occurred. Macrobiotus echinogenitus Richters, 1904 was probably confused with M. harmsworthi Murray, 1907 a. Da Cunha (1941) described the observed specimens attributed to that species as having three macroplacoids instead of two. Some years later and without other comments, Da Cunha (1947b) reported the presence of the species in other Portuguese stations. The first records of Macrobiotus harmsworthi and M. richtersi Murray 1911 are also doubtful because Da Cunha (1948) reported the synonym name M. schultzei Greeff, 1866 . Fortunately, both species have been recorded in Portugal some years later ( Fontoura, 1981). Echiniscus bisetosus Heinis, 1908 , according to Maucci (1985), is not a valid species and the specimens attributable to this species belong to other species of the blumi group ( E. blumi Richters, 1903 ; E. canadensis Murray, 1910 ; E. mediantus Marcus, 1930 ; E. trisetosus Cuénot, 1932 ), all of them already recorded in Portugal. According to Binda & Guglielmino (1982) Echiniscus bisetosus , and other elements of the series blumi-canadensis have probably to be attributed to E. blumi . Very probably, Bryodelphax tatrensis ( Węglarska, 1959) is present in Portugal (the description and pictures of Bryodelphax parvulus Thulin, 1928 presented by Da Cunha (1941) seems to match with B. tatrensis ). If so, the first Portuguese record of B. parvulus must be attributed to Maucci & Durante- Pasa (1984c). On the other hand, Table 5 also shows that some Districts are very poorly surveyed and the number of Portuguese species will be probably much higher.
