Abstract
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-fi n spines, reduction of the squamation between dorsal and anal-fi ns rays, forâmen between infraorbital plate 3+4 and plate 5 smaller, deeper entopterygoid, premaxilla with teeth on its entire dentigerous surface, caudal-fi n base spot not ocellated, fewer pleural ribs, more scales on E1 series, shorter last dorsal-fi n spine, shorter last anal-fi n spine, longer snout, wider head and shorter lower jaw. A new diagnosis for C. orientale, without overlapping character states, is herein presented.
