Molecular data resolving the systematics of the related Blattellidae genera Symploce, Episymploce, and Blattella (Blattodea: Blaberoidea)

Members of the morphologically and ecologically diverse Blattellidae provide a dilemma: their systematic assignment, whether similar or different, is uncertain. We pay special attention to several taxa: Episymploce Bey-Bienko, 1950 Symploce Hebard, 1916, which were strongly disputed because extremely generic diagnosis in past century, one brachypterous species Blattella Caudell, 1903, can be easily distinguished from other macropterous members, but at risk being misassigned genera on basis morphological characters. address phylogeny using DNA sequences (mitochondrial 12S rRNA , 16S COII nuclear 28S histone H3 ) broad sample taxa. A new genus ( Centrocolumna gen. nov .) four ericea sp. nov. nigra tubercularis foliolata are established characters combined with molecular data. The phylogenetic results indicate relationships (( + . Furthermore, we delimited taxonomic status 12 combinations, involve
