Short description
Identification keys | Morphology | Morphometrics
Dorsal soft rays (total): 7; Anal soft rays: 5. The species is distinguished by the following characters: presence of 5 branched anal-fin rays (vs. 7); premaxilla broad elongate (vs. narrow, short), 25-29 premaxillary teeth (vs. 9-10); tooth cusps symmetrically bifid, spatulate and tips not diverged from one another along midline (vs. cusps asymmetrically bifid, or symmetrically bifid with tips diverging from one another along midline); further distinguished from L. wahari
by having odontodes along entire length of the ventral surface of the first pelvic-fin ray (vs. no odontodes from proximal portion of ventral surface); accessory premaxillary teeth present (vs. absent); anal fin dusky (vs. intense pigment band along fin base and diffuse spot at midlength of fin rays); adipose fin with an ossified spine along its anterior edge; further distinguished from L. villosus by having a 9 branched pectoral-fin rays (vs. 8); first lateral cheek plate laminar, broad (vs. thin, narrow rod); trunk plates of dorsal and ventral series small, not contacting those of midline series posteriorly (vs. large plates, contacting plates of midline series at least posteriorly); snout region uniformly pigmented or mottled (vs. presence of a dark pigment band lateral to nares) (Ref. 83588).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.6250 [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.
