Short description Identification keys | Morphology | Morphometrics

This species is distinguished from its congeners by the following characters: teeth with 3/3 multicusp pattern (vs. 3/3-4 in R. lopheliae ; 3/2 in R. rubicundus); prebranchial pores 15 (vs. 26 in R. eos, 19-21 in R. lopheliae); trunk pores 50 (vs. 75-77 in R. eos, 62 in R. rubicundus); tail pores 19 (vs. 26 in R. eos), total pores 80 (vs. 128-130 in R. eos, 100-102 in R. rubicundus) and by having two bilaterally symmetrical nasal-sinus papillae (vs. no nasal-sinus papillae in R. eos and R. lophelia) (Ref. 123790).

Size of 27.5 cm TL is that of an immature female. Collected with a galvanized metal minnow trap where the bottom was nearly flat, covered with fine grey sediment and occasional lava boulders (ca. 0.5 in diameter) in the vicinity of other large lava reefs (Ref. 55621). Minimum depth from Ref. 58018.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.9 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Low vulnerability (18 of 100).
