Comments on the Distribution of Trimerodytes yunnanensis Rao et Yang, 1998 (Squamata: Natricidae) with Remarks on its Pholidosis, Natural History, and Conservation Status

The distribution range of the species Trimerodytes yunnanensis is revised based on preserved specimens and literature data review. Comparing morphology, colour pattern, and classification history of Trimerodytes aequifasciatus form Myanmar (Sagaing) and T. percarinatus previously reported from northeast India (Arunachal Pradesh), Myanmar (Kachin) and Thailand (Chiang Mai) proved to be misidentifications of T. yunnanensis. Trimerodytes yunnanensis is recorded for India for the first time. We propose to remove Trimerodytes aequifasciatus from the species list of Myanmar and T. percarinatus from the species lists of India, Myanmar, and Thailand. The natural history and conservation status of T. yunnanensis is discussed. A diagnostic key for the species of the genera Trimerodytes and Isanophis is provided.
