<i>Euborlasia</i> Vaillant, 1890 (Nemertea: Pilidiophora) from Bocas del Toro: description of a new species, with comments on the systematics of the genus
Available for editors [request]
Members of the lineid heteronemertean genus Euborlasia Vaillant, 1890 are relatively large-bodied ribbon worms, often with mottled, dark coloration. We describe Euborlasia maycoli sp. nov. from Bocas del Toro, Panama, which represents the 11th member, as well as the first Caribbean representative of the genus. We infer the phylogenetic position of the new species among the family Lineidae based on phylogenetic analyses using partial sequences of the mitochondrial 16S rRNA and cytochrome c oxidase subunit I, the nuclear 18S and 28S rRNA, and histone H3 genes. The resulting phylogenetic tree suggests that Euborlasia is likely related closely to Corsoua Corrêa, 1963.
