Short description Morphology | Morphometrics

Dorsal spines (total): 3; Dorsal soft rays (total): 27; Anal spines: 0; Anal soft rays: 29; Vertebrae: 38. This species of hemerocoetine trichonotid is distinguished by the following characters: dorsal fins 2 and well separated, D III, 27 with the spines rooted closely together, first dorsal fin with the first spine greatly elongated, second and third moderately extended, a fused pterygiophore complex placed between 4th and 5th neural spine and 5th spine bent down below complex, the second dorsal fin with 27 unbranched segmented rays, mid-fin rays greatly elongated; A 29, all but first two rays branched, none elongated; short pectoral fin, 17-18 rays, branched except one to three uppermost and one or two lowermost; P I,5, all rays branched and not elongated; extended filamentous uppermost branched caudal-fin ray; presence of a prominent maxillary spine; absence of barbels on head; dorsal operculum present on iris; head mostly scaled except cheek; lateral-line scales about 40, each large and with scalloped posterior margin; gill rakers 2 + 13; precaudal 10, caudal 28, total 38 vertebrae (including urostyle). Colouration: prominent bright-yellow midlateral stripe from pectoral-fin insertion to posterior body; a dorsal stripe along base of soft dorsal-fin rays extending out along upper portion of caudal fin; a ventral lateral stripe from mid-abdomen to base of caudal fin just above level of anal-fin base; three bright-yellow oblique bars anteriorly, one under the eye, second on opercle, and third over pectoral-fin base; branchiostegal rays bright yellow (Ref. 123048).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = No PD50 data   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
