| dc.description.abstract | Euraphia eastropacensis sp. nov., of the tropical Eastern Pacific, is distinguished from its tropical Western Atlantic congener, E. rhizophorae, by morphological and electrophoretic evidence. Because of the apparent recent radiation of high intertidal chthamaloids and the recent closure of the Isthmus of Panama, one would expect that these two species of Euraphia were geminates. However, utilizing electrophoretic data, a large genetic distance value (0.95) was found, and this creates difficulties when explaining speciation between the two in terms of the molecular clock. A molecular evolutionary interpretation of the data suggests that the two species may have speciated before the closure of the Isthmus of Panama, probably as early as the Upper Miocene. | |
