Distribution: D. laternatus is found in warmer waters from off San Diego, California, to 

 about 33° S, off Chile (Fig. 41). Occurrence in the coastal waters of Chile, which are normally 

 quite cold, may be due to a tongue of submerged warm water present along the coast at a depth 

 of about 300 m to as far as 40° S (Wooster and Gilmartin, 1961).

Discussion 



Diogenichthys panurgus Bolin (1946), a small species (to 23 mm) more related to D. 

 laternatus than D. atlanticus, occurs in the Indian Ocean. A very similar form (possibly a new 

 species) is known from the Indo-Pacific region and the far western Pacific but has not been 

 reported from the central or eastern Pacific Ocean.
