Triphoturus mexicanus (Gilbert, 1890) .

Mexican Lampfish. To 9 cm (3.5 in) SL (Personal communication: Scripps Institution of Oceanography Fish Collection, La Jolla, California). British Columbia (Gillespie 1993) to off southern Mexico (Rodríguez-Graña et al. 2004), including Gulf of California (De La Cruz-Agüero and Galván-Magaña 1992). Depth: surface to perhaps 2,882 m (9,453 ft) (min.: Personal communication: Scripps Institution of Oceanography Fish Collection, La Jolla, California; max.: Personal communication: Los Angeles County Museum of Natural History Fish Collection, Los Angeles, California). Maximum depth poorly known, most captures appear to be in 1,000 m (3,280 ft) or less. Deeper records, such as 4,100 m (13,448 ft) (Personal communication: Scripps Institution of Oceanography Fish Collection, La Jolla, California), are based on the maximum depth fished by a midwater trawl and may represent a catch shallower than the maximum depth. Triphoturus oculeus (Garman 1899) has been considered to be synonymous with Triphoturus mexicanus Gilbert, 1890 . However, on the basis of both DNA and larvae characters Rodríquez-Graña et al. (2004) separated the two species. Triphoturus oculeus is found from 13°N to 35°S.
