Spiniphryne gladisfenae (Beebe 1932) 



Materia/.— LACM 36073-2, 18 mm SL, stn 94. 



Spiniphryne gladisfenae was previously known 

 only from the Atlantic Ocean (Bertelsen and 

 Pietsch 1975): three specimens collected from the 

 eastern tropical Atlantic, and the holotype from 

 off Bermuda. A fifth specimen, collected in the 

 Banda Sea by the Alpha Helix, is the first record 

 from the Pacific.
