" Cichlasoma zarskei sp.n. is herein described from the rio Maranhão basin, northern Brazil. The new species differs from all its congeners, except C. orientale, by having a conspicuous posterior band of the longitudinal stripe and dorsal, anal and caudal fi ns faintly dotted. It is also distinguished from its congeners by the precense of the following character states: trisserial predorsal squamation, four anal-fin spines, reduction of the squamation between dorsal and anal-fins rays, forâmen between infraorbital plate 3+4 and plate 5 smaller, deeper entopterygoid, premaxilla with teeth on its entire dentigerous surface, caudal-fin base spot not ocellated, fewer pleural ribs, more scales on E1 series, shorter last dorsal-fin spine, shorter last anal-fin spine, longer snout, wider head and shorter lower jaw. A new diagnosis for C. orientale, without overlapping character states, is herein presented "
