Ixodes cordifer Neumann, 1908d . An Australasian species, all of whose parasitic stages, including the undescribed larva, have been found on Primates : Tarsiidae ; adults alone have been collected from Diprotodontia : Phalangeridae , Petauridae and Macropodidae ; immature stages have been recovered from Rodentia : Muridae , Dasyuromorphia : Dasyuridae , and Passeriformes (several families). There are no records of Ixodes cordifer causing human parasitism. M: Neumann (1908d) F: Schulze (1935b) ; see note below N: Schulze (1935b) ; see note below L: undescribed Redescriptions M: Nuttall and Warburton (1911) , Krijgsman and Ponto (1932) , Roberts (1970) F: Roberts (1970) N: none Note: Roberts (1955) rejects the description of the female of Ixodes cordifer in Schulze (1935b) , but the description of the alleged female and also the male of Ixodes cordifer in Roberts (1955) were later ( Roberts 1960 ) said to represent a new species, Ixodes confusus . The description of the female of Ixodes cordifer by Schulze (1935b) is valid. Roberts (1970) states that the nymph of Ixodes cordifer is unknown, but there is no reason to invalidate the succinct description in Schulze (1935b) . Camicas et al. (1998) list the larva of Ixodes cordifer as described, but no formal description of this stage has been found
