description

Description Morphometric data appear in Table 3. Males larger than females, largest male examined 77.5 mm SL, largest female 57.3 mm SL. Dorsal profile weakly convex from snout to end of dorsal-fin base, approximately straight on caudal peduncle; no distinctive adipose ridge on frontal region. Ventral profile convex from lower jaw to end of anal-fin base, nearly straight on caudal peduncle. Greatest body depth at level of pelvic-fin base. Body moderately deep, slightly compressed. Snout slightly pointed and jaws moderately elongated. Tip of both dorsal and anal fin rounded. Anteromedian rays of anal fin of female not lengthened; distal portion of anal fin thickened in female. Caudal fin rounded. Pectoral fins elliptical, posterior margin on vertical between base of 3 rd and 6 th anal-fin rays in males, between urogenital papilla and base of 2 nd anal-fin ray in females. Tip of each pelvic fin reaching between base of 2 nd and 4 th anal-fin rays in males, between urogenital papilla and base of 1 st anal-fin ray in females. Pelvic-fin bases separated by small interspace. Urogenital papilla not attached to anal fin. Dorsal-fin origin on vertical between base of 3 rd and 6 th anal-fin

diagnosis

Diagnosis Distinguished from the remaining species of the A. elongatus group in having 31 - 35 scales on the longitudinal series (vs. about 50 - 75), minute contact organs on uppermost pectoral-fin ray in males (prominent contact organs on most pectoral-fin rays), and seven branchiostegal rays (vs. six).
