Bayesian consensus tree inferred from 28S D2/D3 rDNA under TVM + I + G model (−lnL = 13,024.7812; AIC = 26,067.5625; freqA = 0.1584; freqC = 0.2128; freqG = 0.3327; freqT = 0.2961; R(a) = 1.0917; R(b) = 5.2109; R(c) = 2.5802; R(d) = 0.8631; R(e) = 5.2109; R(f) = 1; Pinva = 0.1293; Shape = 0.8648). Posterior probability values exceeding 50% are given on appropriate clades. The new sequence is in boldface.
