簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 7 - 8; 臀鰭軟條: 9 - 10; 脊椎骨: 35 - 36. Can be differentiated from Pseudecheneis paviei in possessing 14-20 transverse ridges (laminae) of thoracic apparatus (vs. 9-13); from Pseudecheneis paviei and Pseudecheneis sulcatoides in having furcated neural spine of complex vertebra (vs. single); from P. immaculatus, P. tchangi, and P. paucipunctatus in having yellow spots and patches at occipital, post-temporal, origin and base end of the dorsal fin and adipose fin, and caudal fin base (vs. absent or lacking); from Pseudecheneis gracilis and Pseudecheneis stenura in having a shorter caudal peduncle (19.9-30.0% SL vs. 26.0-35.8); from Pseudecheneis sulcata in having a longer pelvic fin, reaching base of first anal fin ray (vs. not reaching); and from Pseudecheneis crassicuada in having a longer pectoral fin, reaching origin of pelvic fin (vs. not reaching); and from Pseudecheneis serracula in having a shorter adipose fin base (length of adipose fin base 125-166.7% in length of anal fin base vs. larger than 200%); and from Pseudecheneis sympelvica in having separate pelvic fins (vs. fused) (Ref. 74729).
Body shape (shape guide): elongated.
