Bayesian posterior probability node support values greater than 0.7 shown. Coloured diamonds indicate specimens from the IBVNet project coloured by collection site (KA1: red; TN01: purple; TN02: green; TN08: blue; TN10: orange; TN11: yellow; TN12: black) with specimen number followed by GenBank accession number in brackets.
