Diagnosis. Argyropelecus aculeatus can be differentiated from its congeners by the following combination of characters: dorsal blade high, its height equal to the width of its base; post-abdominal spines well developed, posterior larger than anterior; ventral keel extending along body margin; AN and SC well separated; lower jaw with a pair of large canine-like teeth; spines present ventrally and anterior to subcaudal photophores.
Meristic description. Fin rays: D 9; A 11–13; P 1 9–11. Gill rakers: 15–17 (6–7+2+7–8). Photophores: BR 6; I 6; AB 12; SAB 6; PAN 4; AN 6; SC 4.
Distribution. Worldwide in tropical and subtropical waters, probably occurring along the entire Brazilian coast.
