Forward and reverse DNA sequences were assembled, and
edited using Chromas version 2.23 [46], BioEdit v. 5.0.6 [47]
and CodonCode v.3.01 (CodonCode Corporation, Dedham,
MA). Alignment and homology analysis were performed using
CLUSTAL X v. 1.8 [48] and MEGA 4 [49] with pairwise
nucleotide sequence divergences calculated using the Kimura
2-parameter (K2P) model [50]. Base composition and distance
summaries were obtained using the tools provided on the
BOLD workbench (www.boldsystems.org) [38], but only
sequences ≥ 350 bp were included in the analysis.
