Two new cryptic species of Microhyla Tschudi, 1838 (Amphibia, Anura, Microhylidae) related to the M. heymonsi group from central Vietnam

The <i>Microhyla heymonsi</i> species complex from central Vietnam was examined, and based upon morphological and molecular evidence, two new species are described. The discovery of <i>Microhyla daklakensis</i> <b>sp. nov.</b> and <i>Microhyla ninhthuanensis</i> <b>sp. nov.</b> brings the total number of known species in the genus to 46 and the species number of <i>Microhyla</i> in Vietnam to 13. The Truong Son Range harbors the highest diversity of the genus <i>Microhyla</i> with 11 recorded species so far. However, this apparent micro-endemic diversity is at risk because of habitat loss by deforestation, which highlights the necessity of further research leading to improved conservation measures.
