Sebastodes swifti Evermann and Goldsborough, 1907:285, 
fig. 36 (original description, two specimens: holotype, 
USNM 57821, sex unknown, 128.2 mm , Albatross sta- 
tion 4234, Yes Bay, Alaska; paratype, USNM 126656, 
sex unknown, 75.2 mm , Albatross station 4246, Kasaan 
Bay, Alaska, 185-225 m depth, 11 July 1903). 
Zalopyr aleutianus: Jordan et al., 1930:365 (new com- 
bination). 
Sebastes aleutianus'. Barsukov, 1970:997 (new combina- 
tion; comparison with S. borealis). 
Diagnosis 
This species of Sebastes is distinguished from all other 
species except S. melanostictus in having eight pairs 
of head spines and two or more infraorbital spines. It 
is distinguished from S. melanostictus by the following 
combination of color patterns and morphological and 
genetic characteristics: body pale, distinct spots absent 
on the membranes of the spinous dorsal fin; dorsal-fin 
spine 1 shorter, 1. 5-3.0 times into orbit length, 4. 3-7.2% 
SL (vs. 1.0-1. 8 times into orbit length and 5. 9-9. 6% SL); 
dorsal-fin spine 4 shorter, 9.8-15.5% SL (vs. 12.0-18.4% 
SL); gill rakers shorter, 3. 4-6. 3% SL (vs. 3. 9-7.1% SL), 
and fewer, 29-34 (vs. 30-36) (Table 2). Genetically diag- 
nosed by a combination of the presence of protein vari- 
ants ACP*100, either IDDH*100 or * 500 or both, either 
PGM-2*100 or *83 or both, and XO*100 (Hawkins et al., 
2005); homozygosity at microsatellite allele pSma6*183 
(Gharrett et al., 2005, 2006); and mitochondrial haplo- 
type B of Gharrett et al. (2005, 2006). 
Description 
D XII-XIV (XIII), 12-14 (14); A III, 6-8 (8); PI 17-19 
(18), 4-9 (6) simple; lateral-line pores 30-34 (31), scales 
42-57; infraorbital spines 2-10 (9); gill rakers 29-34 
(8-10 + 21-24) (31:9+22); vertebrae 27 (10+17); pyloric 
caeca 9-12. Meristic frequency and statistical data are 
presented in Tables 1, 2, 4, and 5.
