diagnosis
Diagnosis Similar to S. parallelus and S. cholopteryx, and distinguished from all other cynolebiatins by the absence of pelvic fins and pelvic girdle. Differs from S. parallelus and S. cholopteryx in having the dorsal-fin origin anterior to anal-fin origin (vs. posterior), more dorsal-fin rays in males (19 - 22, vs. 17 - 18), fewer anal-fin rays in males (17 - 19, vs. 20 - 23), iridescent dots on unpaired fins in males (vs. iridescent dots absent), and pectoral fins red, with metallic blue spots in males (vs. hyaline).
