FIGURE 3 in Further specimens and phylogenetic position of the recently described leaf turtle species Cyclemys gemeli (Testudines: Geoemydidae)
FIGURE 3. Fifty-percent majority rule tree based on mixed-model Bayesian analysis of three nuclear DNA fragments (C-mos: 573 bp; Rag2: 628 bp; R35 intron: 1075 bp) of leaf turtles (Cyclemys).

FIGURE 2 in Further specimens and phylogenetic position of the recently described leaf turtle species Cyclemys gemeli (Testudines: Geoemydidae)
FIGURE 2. Phylogenetic hypothesis for Cyclemys species as revealed by Bayesian analysis of 984 bp of the mitochondrial cyt b gene. Numbers preceding species names are GenBank accession numbers or voucher numbers (CAS —California Academy of Sciences; FMNH—Field Museum of Natural History; MTDT—Museum of Zoology Dresden, tissue collection). A, B, C denote haplotypes of C. gemeli. Haplotype A was identified in two samples (MTDT 5055- 5056). The cyt b sequence of the type specimen of C. gemeli (AM931656; Fritz et al. 2008) is identical with haplotype C. Numbers along nodes indicate posterior probabilities. Under ML and MP, bootstrap support of each note is 100%. Note that C. enigmatica clusters within C. dentata, suggesting introgressive hybridization (for details, see Fritz et al. 2008).
