Remarks. Our specimens agree well with the detailed description of this species given in Miyake & Baba (1970).

The dorsal series of tubercles on the abdominal tergite 3 and maxilliped 3 merus spinulation ensures the identification of this material as M. speciosa separating it, at the same time, from the allied Munida rutllanti Zariquiey Álvarez, 1952 not represented in our collection but reported in previous works from Mauritanian waters. In our opinion, the similarity of both species and potential misidentifications make it difficult to provide a clear picture of the distribution of each species in northwest Africa.

Distribution. Senegal to north of Namibia, in depths from 108 to 809 m (Baba et al. 2008; Muñoz et al. 2012). Our records increase the northern distribution to Mauritania.
