| abstract | Aponomma (Bothriocroton) glebopalma, n. subgen., n. sp., and Amblyomma glauerti, n. sp. (Acari: Ixodidae), are described from the monitor lizards Varanus glebopalma Mitchell and Varanus glauerti Mertens in Western Australia and the Northern Territory, Australia. The new subgenus is erected to accomodate A. (Bothriocroton) glebopalma, a new species with a deeply pitted and pilose scutum in both the adult and immature stages, unlike all other described species of Aponomma. This new species is found in an area where Aponomma fimbriatum Koch, a parasite of varanid lizards and various species of snakes, was the only known member of the genus found in both Western Australia and the Northern Territory |
