Front of head rounded with tangent to apex of its curve about 60° from horizontal axis; mouth slanted obliquely upwards, forming an angle of about 70° to horizontal axis of body; lower jaw slightly projecting; maxilla extending posteriorly to level of front of pupil; anterior narial tube short, not reaching posterior margin of upper lip; gill opening extending forward to a vertical at posteroventral edge of vertical limb of preoperculum; cephalic sensory-canal pore system lacking only an IT pore; cutaneous sensory papillae pattern obscure; male urogenital papilla a flat rounded plate; urogenital papilla of female small and rounded.
First dorsal fin triangular, first spine filamentous, reaching to first soft ray of second dorsal fin when adpressed. Pectoral-fin rays apparently unbranched (but ends broken), fin long and apparently pointed, reaching at least to below middle of second dorsal fin. Fifth pelvic-fin ray absent; fourth pelvic-fin ray broken, except for part of one ray with 2 elongate branches on paratype.

Etymology

The specific name is from the Latin lentiginosus (full of freckles), in reference to the many tiny dark spots covering the yellow head and body.
