Genus Eulychnia

According to the results given by Larridon et al. (2018) a population of Eulychnia from south of Rio Huasco Valley (informally named “ Eulychnia spec. aff. acida ”) should be regarded as a new species since phylogenetic analyses revealed that this taxon is more closely related to E. chorosensis Klaassen (2011: 172) and E. castanea Philippi (1864: 80) than to E. acida Philippi (1864: 80) . Eulychnia spec. aff. acida resulted sister to the rest of “Clade 2” and not clustered with E. acida samples collected at south and north of the distribution of the specie, these results led us to propose this taxon as a new specie.
