Abstract

The mitochondrial (mt) cytochrome oxidase I (COI) gene was studied in specimens of the chiton Ischnochiton striolatus (Gray 1828) from Isla de Margarita and surrounding areas along the coast of Venezuela to understand their haplotype diversity, and to evaluate the relationship of this species with the closely related chitons Ischnochiton papillosus (C. B. Adams 1845) and Ischnochiton erythronotus (C. B. Adams 1845). Two haplotypes were observed among the I. striolatus samples. A pairwise identity of 94.3% supports that the entities currently described as I. striolatus might be, in fact, two reproductively isolated species. Samples of I. erythronotus grouped within one of the I. striolatus haplotypes, which indicates that these two nominal species are synonymous. Preliminary results indicate that I. papillosus is a distinct species. ^
