Type host: Plecotus auritus (Linnaeus, 1758), Long-eared bat.

Remarks: Gottschalk (1969) found spheroidal to subspheroidal oocysts (?) in the large intestine that measuered 16 x 14 (13-18 x 12-16), with a colorless, thin wall. Since neither sporocysts nor sporozoites were described, this form cannot be placed in the genus Eimeria and must be considered a species inquirendae until it can be described more completely. The only other oocysts ever found in bats of this genus were those of Klossia variabilis (Adeleidae) by Levine et al. (1955), but they thought K. variabilis probably was a pseudoparasite of the bat and a true parasite of some other invertebrate that the bat had eaten.
