简单描述 型态特徵 | 形态测量图

This medium-size species is distinguished by the following set of characters: disc wider than long, width 47.1-50.3% TL, length 42.0-43.6% TL; head short (dorsal head length 15.2-16.2% TL; ventral head length 21.6-22.9% TL); snout relatively short (preorbital length 10.1-11.1% TL; ventral snout length 11.2-12.1% TL); interspiracular distance 5.3-5.9 TL, internasal distance 6.2-6.8% TL, preorbital length 2.4-3.0 times orbit length and 2.9-3.6 times interorbital; dorsal fins two, interdorsal space 1.1-1.9% TL; tail width at pelvic-fin axil 0.9-1.6 times its height; preorbital thorn single and small ; dorsal and most of ventral surface of disc entirely velvety, covered with fine denticles; adolescent male with median disc and pelvic fins naked; in females, anterior pelvic-fin lobe naked (skin naked or with sparse denticles ventrally on mid belly, chin, nasal curtain, and around cloaca); tail is long and slender, entirely velvety and without thorn-like denticles; lateral tail folds are moderately well developed; nasal lobes expanded, width of nasal curtain 7.9-8.3% TL; anterior pelvic-fin lobe is slightly shorter or similar length to posterior lobe; dorsal and ventral surfaces are greyish brown to dark bluish grey; total pectoral-fin radials 58-60; monospondylous centra 23-25, total diplospondylous centra 103-106, total centra 126-131 (Ref. 116308).

生物学特性     字汇 (例如 epibenthic)

The species is known from three type specimens consisting of two females (45.9 and 45.8 cm TL) and an adolescent male (36.3 cm TL); based on the adolescent male size, the females are most likely adults (Ref. 116308).
