Similar Species |
Sirembo amaculata differs from other species of Sirembo in the coloration that changes ontogenetically from a pale abdomen and alternating black and white horizontal bands on the body in smaller specimens (165–175 mm SL) to a darker abdomen and vermiculate bands in larger specimens (295–405 mm SL). The species also differs in the following combination of characters: pelvic fins inserted below preopercle; prepelvic length 15.5–20.5% SL; 17–20 scale rows between origin of dorsal fin and lateral line; 3–4 long rakers on anterior gill arch; pseudobranchs with 24–40 filaments; and pectoral fins with 24–28 rays. S. amaculata is most similar to S. jerdoni, with horizontal and oblique stripes on the head and body and an indistinct lateral line. S. amaculata differs from S. jerdoni by the number of scales between the origin of the dorsal fin and the lateral line (17–20 vs. 5–7) and by having a longer pelvic fin (19.0–25.0% SL vs. 12.5–15.5% SL, respectively). |
