Fig 1. Maximum likelihood tree of 112 individuals belonging to the subgenus Hylobatrachus, based on DNA sequences (507 bp) of the mitochondrial 16S gene.

The inset pictures show representative individuals of the respective species. Values at nodes are support values in percent of a bootstrap analysis (2000 replicates). The tree was rooted with Mantidactylus femoralis (subgenus Ochthomantis) as the outgroup (removed from the graphic for better visualization of ingroup relationships). The inset haplotype network is based on haplotypes inferred from 572 bp of the nuclear RAG1 gene for 54 individuals (haplotypes numbered H1–H14). Colours correspond to those used in the tree.
