NOTE.—RI, retention index CI, Consistency index.

^a The 2 mtDNA partitions were treated as a single partition in parsimony searches.

^b Base frequencies and substitution rates from the best fit model found by Mr. Modeltest version 2.2 (Modeltest version 3.7 for combined data set) using the Akaike information criteria. Observed base frequencies are given in parentheses.

^c Results from parsimony searches for the coded-gaps data set (results from uncoded-gaps data set in parentheses).
