树蛙家族再添新物种

Core Findings - A new species of tree frog named "Motuo Tree Frog" has been discovered in Motuo County, Tibet, by a collaborative research team from various institutions [1][2] - The research was published in the international journal "Animal Systematics and Evolution" [1] Research Methodology - The research team conducted in-depth investigations in the mountainous areas of Motuo County, at altitudes ranging from 500 to 1700 meters [1] - Initial identification categorized the frogs as known species, but detailed morphological comparisons and molecular phylogenetic analyses revealed their true identity as a new species [1] Species Characteristics - The Motuo Tree Frog has a medium body size, with adult lengths ranging from 31.6 mm to 55.5 mm [1] - Distinctive features include a reddish-brown or gray-green back, unique skin protrusions at the tip of the snout, black spots on the sides, and prominent triangular skin folds at the ankle joints [1] Significance of Findings - The study highlights significant morphological and genetic differences between the Motuo Tree Frog and the previously known Two-spotted Tree Frog [2] - The research reevaluated the geographical distribution of the Two-spotted Tree Frog, confirming its range is limited to northern India and central-western Myanmar, contrary to previous beliefs of a broader Southeast Asian distribution [2] - The discovery contributes to the understanding of amphibian diversity and evolution in the Himalayas, providing essential data for biodiversity conservation policies in Tibet [2]
