PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON 111(4):936-941. 1998. A new species of the genus Bellator (Pisces: Triglidae), with comments on the trigloids of the Galapagos Islands William J. Richards and John E. McCosker (W.J.R.) NOAA Fisheries, Southeast Fisheries Science Center, 75 Virginia Beach Drive, Miami, Florida 33149, U.S.A.; (J.E.McC.) California Academy of Sciences, Golden Gate Park, San Francisco, California 94118, U.S.A. Abstract. — A new, endemic species, Bellator farrago, is described from the Galapagos Islands. It differs from its congeners by a combination of characters including absence of a supplemental preopercular spine, short first dorsal fin spine, produced rostral spines, and lack of scales on the breast and interpelvic area. The Galapagos trigloid fauna comprises: B. farrago, Prionotus miles, Pr. stephanophrys, and Peristedion crustosum. The fishes of the New World genus Bel-lator were revised by Miller & Richards (1991); they treated four Atlantic species and three eastern Pacific species. Recent collecting in and around the Galapagos by the submersible Johnson Sea-Link revealed the presence of an undescribed species. The submersible captured one specimen and an-other was found in the California Academy of Sciences Fish Collection. Prior to this study only one Bellator was known from the Galapagos based on Gruchy (1970), who added Prionotus loxias {= Bellator lox-ias) to the Galapagos fauna. A re-exami-nation of the Gruchy specimens reveals that they also are this undescribed species and not B. loxias. This new species is diagnosed and described, and details of its habitat are provided based on observations made from the submersible. The submersible also cap-tured three specimens of Peristedion crus-tosum Garman which is a new record of this species from the Galapagos.
