Myobiidae (Acarina, Trombidiformes) associated with minor families of Chiroptera (Mammalia) and a discussion of phylogeny of chiropteran myobiid genera.

Three new genera, Natalimyobia n. gen., Furipterobia n. gen., and Mizopodobia n. gen., are erected for the myobiid mites associated with the chiropteran families Natalidae, Furipteridae, and Myzopodidae, respectively. The definitions for the genera Nycterimyobia, Thyromyobia, and Mystacobia, previously known only from one sex, are refined with the description of the opposite sex. Two different types of myobiid genera, one being represented by larger elongate forms and the other by smaller rounded forms, often share hosts within a chiropteran family. A larger elongate myobiid genus is associated exclusively with each chiropteran family. Phylogenetic relationships among 16 larger-sized myobiid genera, including the 3 new ones, are deduced based primarily on the structure of female genitalia and secondarily on the formation of legs and chaetotaxy of idiosoma and legs. These relationships are regarded as being parallel to those of the chiropteran host families.
