A New Cryptic Species of the Theloderma asperum Complex (Anura: Rhacophoridae) from Myanmar
I describe a new species of Theloderma from two regions in Myanmar (Chin State in western Myanmar and Kachin State in northern Myanmar). Highly similar in appearance and size to Theloderma albopunctatum and Theloderma asperum, the new species differs by the presence of small, bilateral vocal sac openings absent in T. albopunctatum and T. asperum. Molecular phylogenetic analysis from two mitochondrial and four nuclear gene fragments infers that individuals are members of a unique genetic lineage within the T. asperum Complex.Abstract

The phylogenetic consensus tree derived from partial DNA sequences of the concatenated 16S-COI mitochondrial genes based on Bayesian analysis (scale bar: 0.04 estimated substitutions per site). Numbers above branches are Bayesian posterior probabilities (probabilities less than 70% are not shown). Numbers of specimens correspond to Table 2.
The phylogenetic consensus tree derived from concatenated DNA sequences of the BNDF, SIA, RHO and TYR nuclear genes based on Bayesian analysis (scale bar: 0.006 estimated substitutions per site). Bayesian posterior probabilities values > 0.95 shown as * left of slash (probabilities less than 70% are not shown). Numbers of specimens correspond to Table 2.
