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

The Microhyla heymonsi species complex from central Vietnam was examined, and based upon morphological and molecular evidence, two new species are described. The discovery of Microhyla daklakensis sp. nov. and Microhyla ninhthuanensis sp. nov. brings the total number of known species in the genus to 46 and the species number of Microhyla in Vietnam to 13. The Truong Son Range harbors the highest diversity of the genus Microhyla 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.

Automated summary

Based on morphological and molecular evidence, two new species from the Microhyla heymonsi species complex in central Vietnam have been described. The Truong Son Range in Vietnam holds the highest diversity of Microhyla genus, but faces the risk of habitat loss due to deforestation, emphasizing the need for further research to enhance conservation efforts.
