Echinonyssus butantanensis — Tenorio 1984: 265 ; Mašán & Fend’a 2010: 121 , figs 113–116. Type locality : Brazil , Sao Paulo . Type series : Brazil , Sao Paulo , Butantan Institute . Type host : Mus musculus (Linnaeus, 1758) , albino morph (the white mouse) Host range : H . butantanensis prefers murine rodents of the genera Mus and Rattus ( Mašán & Fend’a 2010 ). Distribution : Virtually cosmopolitan; the tight association of H . butantanensis with synanthropic rodents possibly explains its finding from areas far remoted from the type locality, e.g. in New Zealand ( Tenquist & Charleston 2001 ). In Asiatic Russia , the species has been known (as H . latiscutatus ) from Western Siberia and the southern parts of Eastern Siberia ( Davydova & Nikol’sky 1986 ; Nikulina 2004 ). Notes: In Russian parasitological and acarological literature the name H . butantanensis is not in common use; most authors have used the name H . latiscutatus (see, for example, Zuevsky 1970 ; Nikulina 2004 ). The identity of Schrank’s (1803) mite species Acarus musculi ( type host—the house mouse) is enigmatic due to the brevity of its original description and loss of the type series. Some authors (e.g. Baker & Wharton 1952 ) assigned this species to the genus Steatonyssus Kolenati, 1858 . However, Steatonyssus mites are obligatory parasites of bats, and the finding of a member of this genus on the skin of a house mouse is very unlikely ( Till & Evans 1964 ).
