Spence Bate and Ortmann consider this species to be Lucifer reynaudii 

 M. Edw., but Milne Edwards's description and figure are not sufficient for 

 identification. 



Lucifer acestra has an enormous horizontal distribution throughout the 

 warmer parts of both the Atlantic and Pacific Oceans. See Ortmann, /. c.

The dorsal spine is longer than in the type specimen figured by Sars, and 

 it is minutely denticulated along the margins, as in G. sarsii Wood-Mason,t 

 a form probably not specifically distinct from G wilkmocsii.
