Material examined: Scotia Sea off South Georgia: USNM 356643 (4 specimens; 115-165 mm SL) and SAIAB (RUSI) 60090 (3; 129-202 mm SL), 53°31.2'S, 37°50.9'W, ISLAS ORCADAS coll.

DeWitt. Diagnosis. Bothrocara molle is distinguished from its congeners by it long, slender gill rakers (raker ratio as percent: 163-267) and long pectoral fin, reaching almost to anus in young or just beyond it in adults. Description. Vertebrae 18-20 + 85-91 = 104-110; D 99-105; A 84-89; P 14-15; C 10; pelvics absent; branchiostegal rays 6; gill rakers 5-6 + 16-20 = 21-26; vomerine teeth 0-3; palatine teeth absent in all; pseudobranch filaments 7-10; pyloric caeca 2; gill raker ratio (as percent) 222-267; preoperculomandibular pores 8; suborbital pores 6 + 3; postorbital pores 4; supraorbital (nasal) pores 2; interorbital pore 1; occipital pores absent. Lateral line double, with dorsal branch arching across body to just posterior to anus and mediolateral branch running from just anterior to anus to tail tip. Remarks. The above synonymy, although incomplete, reflects my unpublished work on the genus Bothrocara, revisionary studies of which are in preparation. This species is close to B. brunneum with which it has long been confused. Bothrocara molle is known in the literature from Japan (Masuda et al., 1984) to Chile (as Bothrocara alalonga; ...
