Observation of the Asian Turtle Tick Amblyomma geoemydae Cantor, 1847 (Acari: Ixodidae) on the Asian Leaf Turtle Cyclemys dentata Gray, 1831 in Coron Island, Philippines

Abstract

The Asian leaf turtle (Cyclemys dentata) is a freshwater turtle species found in select Southeast Asian countries, including the Philippines. Our understanding of C. dentata’s ecology in the Philippines is not yet fully understood and documented, and this is derived only from a few studies. In this paper, we present our single-event observation of an ectoparasite interaction between C. dentata and the Asian turtle tick (Amblyomma geoemydae) from Sitio Malbato, Barangay Bintuan Coron, Palawan. Our discovery serves as the second documented instance of this ectoparasite on C. dentata in the Philippines, hence extending its known distribution outside mainland Palawan. This finding contributes to the limited understanding of C. dentata's ecology and underscores the need for further field-based observations, which are crucial for their research and conservation.
