Myobiid mites (Trombidiformes: Myobiidae) associated with the vampire bats (Chiroptera: Phyllostomatidae) and information on host taxonomy deduced from them

Eudusbabekia diphyllis n. sp. and Eudusbabekia diaemis n. sp., parasitic on Diphylla ecaudata and Diaemus youngi, respectively, are described, and measurements for Eudusbabekia arganoi (Vomero) are presented. The vampire bats are here treated as representatives of the family Phyllostomatidae on the basis of the occurrence of these mites on them. These 3 mites are closest to those parasitic on bats of the genus Phyllostomus, among all the known mites of the genus Eudusbabekia, suggesting a phylogenetic affinity between vampire bats and Phyllostomus. Asymmetry of different levels of legs I is observed in adults of E. arganoi and E. diaemis, whereas E. diphyllis bears bilaterally symmetrical legs I. From this, the phylogenetic line, E. diphyllis-E. arganoi-E. diaemis, is proposed on the premise that asymmetry of any part of the external body has been fostered and preserved in the parasites.
