Diagnosis. Cyclothone can be distinguished in the Gonostomatidae by the absence of adipose fin; dorsal- and anal-fin origins about opposite; 12–15 dorsal-fin rays; 16–21 anal-fin rays; 29–35 vertebrae; maxillary teeth close-set, subequal, increasing in size posteriorly; vomerine teeth present or absent, palatine teeth only in an anterior patch; photophores present or absent, SO and isthmus series always absent; when present, photophores along the body in ventral and lateral series, OP 2, OA 6–10; caudal glands present or absent; anus closer to pelvic-fin than to anal-fin origin, or midway between origin of those fins (Grey, 1964; Mukhacheva, 1964, 1974; Badcock, 1982; Nazarkin, 2015). A total of 13 valid species (Fricke et al., 2022).
Remarks. Nine species of Cyclothone were previously reported in the Brazilian EEZ ( Tab. 2). Unfortunately, all collected specimens were severely damaged and could not be identified at the species level (S1).
