Description
Summary:ABSTRACT A new species of Aspidoras from the rio da Dona basin, a small coastal river drainage in Bahia State, is described herein. The new taxon differs from its congeners by presenting infraorbital 1 with well-developed ventral laminar expansion, nuchal plate nearly reaching to or sometimes contacting posterior process of parieto-supraoccipital, anterior tip of nuchal plate just posterior to dorsal margin of first dorsolateral body plate, and blotches on dorsal half of dorsolateral body plates and/or ventral half of ventrolateral body plates fused with midlateral series of blotches, forming three or four enlarged and oblique black blotches. RESUMO Uma nova espécie de Aspidoras da bacia do rio da Dona, uma pequena drenagem costeira do estado da Bahia, é aqui descrita. O novo táxon difere de suas congêneres por apresentar infraorbital 1 com expansão laminar ventral bem desenvolvida, placa nucal quase alcançando ou alcançando o processo posterior do parieto-supraoccipital, extremidade anterior da placa nucal apenas posterior à extremidade dorsal da primeira placa dorsolateral, e três ou quatro manchas pretas grandes na porção lateral mediana do corpo, geralmente inclinadas anterodorsalmente e conectadas à série de manchas dorsais e fusionadas à série ventral de manchas.
