Description: Cambeva luteoreticulata differs from all other congeners by its unique rounded, stapula-shaped caudal fin in specimens above about 40 mm SL (Fig. 8A). Cambeva luteoreticulata is also distinguished from all other congeners of the Cambeva beta-clade, except Cambeva chrysornata Costa, Feltrin, Mattos, Dalcin, Abilhoa & Katz, 2023 and C. papillifera, by having short barbels, with the nasal barbel not reaching the orbit in specimens above 60 mm SL and maxillary and rictal barbels not reaching the interopercular patch of odontodes. Cambeva luteoreticulata also differs from C. chrysornata and C. papillifera by the absence of the anterior segment of the infraorbital series (vs. presence), from C. chrysornata by having more procurrent caudal-fin rays (21 or 22 dorsal and 15 or 16 ventral, vs. 16 or 17 and 11 or 12, respectively) and fewer opercular odontodes (10–12 vs. 18), and from C. papillifera by the absence of hypertrophied papillae on the head surface (vs. presence) and narrow nasal barbel (vs. broad laminar, ribbon-shaped). Cambeva luteoreticulata is also distinguished from all other congeners by a unique pattern of ontogenetic colouration change consisting of flank pale yellow with irregularly shaped and arranged, dark brown to black blotches in specimens below about 40 mm SL (Fig. 9A), becoming dark brown, with small, irregularly shaped pale yellow marks forming reticulate pattern in larger specimens, (Costa et al. 2024). Etymology: The specific name luteoreticulata, From the Latin luteus (saffron yellow) and reticulata (reticulated), in reference to the flank colour pattern of adult specimens, (Costa et al. 2024). |
