Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenweichstrahlen (insgesamt) : 36 - 37; Afterflossenweichstrahlen: 30; Wirbelzahl: 40 - 42. This species is distinguished by the following set of characters: vertebrae 40-42; D 36 or 37; A 30; pectoral-fin rays 28 or 29 rays, deeply notched, with lower lobe reaching to anal-fin origin; large pelvic disk 34.2-34.5% HL (10.3-10.9% SL); teeth are strongly trilobed on both jaws, with inner teeth weakly trilobed or shouldered; cephalic pore pattern 2-6-7-2, chin pores paired; gill slit is above pectoral-fin base. Colouration: body bright red, non-variegated in life (Ref. 131310).

The ovary of holotype pouch-like, translucent whitish, with yolked eggs (0.50 mm maximum diameter); testes of paratype (FAKU 150605) was enlarged, color creamy-white (Ref. 131310).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].

Trophic level (Ref. 69278): 3.1 ±0.5 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
