Relationship.—The diagnosis distinguishes this species from A. callida in gnathopods, pereopods 1 and 2 and epistome. Aceroldes synparis (J. L. Barnard, 1961) differs from A, edax in its broader and shorter hand of gnatbopod 2, narrower anterior coxae, and a distally rounded Figure 46.—Aceroides edax, new species, holotype, male, mm, 7358: a, maxilliped; b,c, mandible; d, lower lip; e,f, maxillae 1,2; g, head and labrum, lateral; h, telson. Aceroides edax closely resembles A. Umicola K. H. Barnard (1925) in its head, telson, gnathopods, and mandible but the latter is said to have coalesced imier lobes of the lower lip, and five or six setae on the inner lobe of maxilla 1 (the specimen is 15 mm long and thus would be expected to have more setae). The principal difference appears to be in the expanded articles of pereopods 1 and 2 of ^. Umicola^ which resemble those of A. latlpes (Sars) (see 1895, pi. 120, fig. 2). Article 2 of pereopods 3 and 4 is not as ovately expanded in A. edax as it is in^. Umicola. One might consider that Aceroides edax and A. synparis (J. L. Barnard, 1964b) (described as Oediceroides {Patoides) synparis) of the Caribbean Sea are an analogous pair of species; Aceroides edax.
