Maximum likelihood tree based on internal transcribed spacer region of ribosomal DNA for family Sphenopidae. Numbers on nodes represent ML and neighbor-joining (NJ) bootstrap values (>65% are shown). Thick branches indicate high supports of Bayesian posterior probabilities (>0.95). Sequences obtained from GenBank are shown with accession numbers.
