Results To examine the degree of congruence between the phylogenies of nine Anicetus species and their scale insect hosts, we used DNA sequence data from mitochondrial (COI) and nuclear (28S-D2) regions to reconstruct the phylogeny of Anicetus species, and analyzed the level of cophylogeny by using distance-based and tree-based methods. Conclusions Cophylogenetic analyses indicated a significant fit between trees using distance-based tests, but no significant cospeciation signal using tree-based tests, suggesting the presence of parasite sorting on related host species. Our results provide insight into the diversification process of Anicetus species parasitizing scale insects. } }
