First record of Eyndhovenia (Mesostigmata: Gamasina: Spinturnicidae) from Vietnam

Eyndhovenia is one of the twelve genera of Spinturnicidae which are highly specialised parasites of bats. Previously known hosts of this genus comprised 17 species of Old World bats: Eptesicus serotinus, Hipposideros larvatus, Miniopterus schreibersi, Myotis blythi, M. emarginatus, Pipistrellus pipistrellus, P. gaisleri, Rhinolophus axillaris, R. blasii, R. clivosus, R. cornutus, R. euryale, R. ferrumequinum, R. hipposideros, R. megachyllus, R. mehelyi, R. rouxi. Within Asia, Eyndhovenia was only recorded from two countries, China and Thailand. Between 2018 and 2020, we conducted a series of bats surveys and recorded of this genus from intermediate horseshoe bat, Rhinolophus affinis, in Vietnam. The present study exhibits the new record in both parasitological and geographical aspects.
