| Summary: | Family Rajidae * Dipturus intermedius (Parnell, 1837) —No common name in Madeira; Flapper skate (Fig. 8 and 9) Günther 1870: 468 (as Raja macrorhynchus sic). Ebert & Stehmann 2013: 317–321 (as Dipturus sp. cf. intermedia). Distribution in Macaronesia. Madeira Remarks. one mounted specimen collected in Madeira by R. T. Lowe (BMNH 1860.8.30.7), named as D. macrorynchus, was identified as D. intermedius by MB. One specimen registered in MMF collection dated from 1943 (MMF 2869), collected with bottom trawl off the west coast of Funchal, could not be located. The Madeiran specimen in the Natural History Museum (London), bears two thorns along the lower edges of tail, at level of dorsal fins, distinctly inclined towards the head (Fig. 9), a character of Dipturus intermedia (Iglésias et al. 2010; Last et al. 2016b). It is most probable that this species also occurs in the Azores and the Canary Islands, but we were not able to see specimens from there and records in the literature are referred to Dipturus batis (see remarks in doubtful records).

Distribution in Macaronesia. Madeira, Azores (Santos et al. 1997 Arruda 1997; Porteiro et al. 2010) and Canary Islands (Brito et al. 2002; Brito Hernández & Sancho Rafel 2003). Remarks. no specimens or other material from Madeira was found in natural history museum collections. Carneiro et al. (2014) refer as existing in MMF collection, but the specimen in question was collected in Portugal mainland. Maul, ... |
