Phylogenetic analyses of the nepalensis group of species in the genus Nicrophorus have revealed a possible case of morphological-based long-branch attraction. Bayesian Inference using the Mkv model was compared with Parsimony using data simulated in both the Felsenstein and Farris zones. Complicating this problem, morphological data strongly conflict with molecular data.
