Ariosoma sp.

( Fig. 2 C)

Material examined. USU 0 0 998, 1 (254.0 mm), MD, 62 CB 103.

Distribution. Ariosoma sp. is known from a single specimen identified earlier by Séret and Andreata (1992) as Gnathophis sp. aff. mystax (Delaroche 1809) .

Remarks. Ariosoma sp. is being tentatively identified in the genus Ariosoma , despite its lower number of lateral line pores to the level of the anus (e.g. 34 in our specimen vs. 46–52 in A. balearicum ); further material is needed for a more precise identification. Leptocephali of A. balearicum were recorded off Brazil by Castro and Bonecker (2004), and may represent the species reported herein, since adults of that species were never reported from the area.
