The genus Muticaria Lindholm, 1925, is currently distributed either in Southeastern Sicily or in the Maltese islands and comprises the species M. syracusana (Philippi, 1836), M. neuteboomi Beckmann, 1990 and M. macrostoma (Cantraine, 1835). For the first time, we report a molecular study on the topotypicous populations of M. syracusana and M. neuteboomi carried out on fragments of the ribosomal 16S rDNA subunit and the cytochrome oxydase I (COI) mitochondrial genes by Neighbour Joining, Maximum Likelihood, Maximum Parsimony and Bayesian Inference algorithms. Our results revealed the existence of nucleotide-sequence divergence (Dxy: 5% for 16S rDNA and 12% for COI sequences) between the two taxa.

Abstract
The genus Muticaria Lindholm, 1925, is currently distributed either in Southeastern Sicily or in the Maltese islands and comprises the species M. syracusana (Philippi, 1836), M. neuteboomi Beckmann, 1990 and M. macrostoma (Cantraine, 1835). For the first time, we report a molecular study on the topotypicous populations of M. syracusana and M. neuteboomi carried out on fragments of the ribosomal 16S rDNA subunit and the cytochrome oxydase I (COI) mitochondrial genes by Neighbour Joining, Maximum Likelihood, Maximum Parsimony and Bayesian Inference algorithms. Our results revealed the existence of nucleotide-sequence divergence (Dxy: 5% for 16S rDNA and 12% for COI sequences) between the two taxa.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
