deskripsi pendek Morfologi | Morfometrik

This species is distinguished by the following characters: disc rhombic to evenly inverse heart-shaped (in adult male), with angled outer corners, its body length to mid-vent shorter than tail length from mid-vent; preorbital snout length 13-15% and distance between first gill slits 15-16% of TL; orbits are large, horizontal diameter 1.1-1.4 times interorbital width; young specimens with 1-3 rows of tail thorns, adults 3-5; more than two interdorsal and nuchal thorns; dorsally, it is largely smooth, but snout tip prickly; with growth, dermal denticles also on anterior margins of disc and inner posterior pectorals, as well as ventrally on snout and anterior margins of disc; ventral snout tip blackish, especially in young specimens; dorsal ground color ocher, anterior snout dusky; its dorsal pattern on disc and pelvic fins consisting of variable dark brown spots encircled with beige pigment and arranged into rosettes; ventral pores are few, tiny, and blackish; long interdorsal and postdorsal tail sections, with high posterior part of epichordal caudal lobe and light edged low ventral keel; 37-42 upper tooth, relatively few pectoral fin radials (71-75); clasper without external pseudosiphon and funnel; inner dorsal lobe with components slit, terminal bridge, and 2 clefts; inner ventral lobe with components shield, dike, rhipidion, sentinel, spike, and two sentinas; terminal clasper skeleton with 3 dorsal terminal, 1 ventral terminal, and 2 accessory terminal cartilages; unlike its congener, its ventral terminal is atypically broad distally, the accessory terminal 1 is only slightly Y-shaped, and the dorsal terminal 2 and the terminal bridge are fused; anterior cranial fontanel with clear-cut contour all around and extending about one fifth into rostral shaft length; subrectangular scapulocoracoid, with rear corner sharply marked; large oval anterior fenestra without anterior bridge, one large oval postdorsal and one lower, moderately large oval postventral fenestra; its pelvic girdle with massive ischiopubic bar with weakly convex anterior contour, posterior contour slightly concave in females and juvenile males but deeply concave in semi adult and adult males; prepelvic processes are moderately long, solid, conical, and straight, their length 2.4-2.9 times median thickness of ischiopubic bar (Ref. 101518).

Bayesian length-weight: a=0.00302 (0.00141 - 0.00645), b=3.24 (3.07 - 3.41), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.6 se; based on size and trophs of closest relatives
Daya lenting (Ref. 120179):  Rendah, Waktu penggandaan populasi minimum 4.5 - 14 tahun (Preliminary low fecundity).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (40 of 100).
