Maximum likelihood tree of nuclear internal transcribed spacer of ribosomal DNA (ITS-rDNA) region for newly obtained sequences from Sphenopus exilis sp. n. in this study along with previously published GenBank sequences of family Sphenopidae. Bootstrap values of ML >60% are shown at respective nodes. Nodes supported by Bayesian posterior probabilities >0.90 are marked with asterisks. Species names’ of sequences obtained from GenBank follow with accession numbers. The subtree shown in b) shows only the clade formed by genus Sphenopus, Palythoa mizigama and P. umbrosa, delineated by the gray square in a).
