TL;DR: The presence of Synodus saurus and Saurida suspicio in Brazilian waters is discussed, and a key to the Western Atlantic Aulopoidei is provided.
Abstract: In this second paper dedicated to report on deep-sea fishes from Brazilian waters, mainly from Bahia, the presence of one family and three species of Aulopoidei is reported for the first time from Brazilian waters: the aulopid Aulopus filamentosus (royal flagfin), the synodontids Saurida normani and Synodus poeyi (shortjaw lizardfish and offshore lizardfish, respectively). The presence of Synodus saurus and Saurida suspicio in Brazilian waters is discussed, and a key to the Western Atlantic Aulopoidei is provided.
TL;DR: Aulopus bajacali, described from the eastern Pacific Ocean from a single specimen, is redescribed and is the only Pacific species of Aulopus belonging with the Atlantic species group of A. nanae, A. filamentosus, and A. cadenati.
Abstract: Aulopus bajacali, described from the eastern Pacific Ocean from a single specimen, is redescribed. It is now known from over 400 specimens. It is the only Pacific species ofAulopus belonging with the Atlantic species group ofA. nanae, A. filamentosus, andA. cadenati. It shares a short dorsal-fin base and some color pattern characters with this group. New distribution records from Ecuador and the Galapagos Islands extend its range; it is now known from mid-Baja California (25°N) to about 3°S in the eastern central Pacific.
