الأشعة الظهرية الناعمة (المجموع) : 7; أشعه شرجية لينه: 7. This species is distinguished from its congeners by the following characters: presence of 8-branched pectoral-fin rays (vs. nine); single (vs. multiple) lateral cheek plate developed as a thin rod (vs. expanded, laminar); trunk plates of dorsal and ventral series large, contacting plates of midline series at least posteriorly (vs. plates small, not contacting those of midline series posteriorly); presence of a dark pigment band on snout (vs. snout region uniformly pigmented or mottled); further distinguished from Lithogenes wahari having odontodes along entire length of the ventral surface of the first pelvic-fin ray (vs. none from proximal portion of ventral surface); accessory premaxillary teeth present (vs. none); 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 leading edge (vs. no spine); further distinguished from L. valencia by the presence of asymmetrically bifid teeth (vs. tooth cusps symmetrically bifid), 7 (vs. 5) branched anal-fin rays (Ref. 83588).
