“…The chaetotaxy of P. africanus and P. simicola is essentially the same (Tables IV, V), including tarsus I with its group of setae, probably corresponding to the 'Haller's organ' of ticks, as suggested by Vitzthum (1930). Two differences were, however, discovered.…”

“…A new genus, Pneumonyssoides, was erected by Fain (1955) for a species from the warthog and for P. caninum. It also includes P. stammeri (Vitzthum, 1930) from New World monkeys. A third genus, Rhinophaga Fain, 1955, comprises mites inhabiting the nasal cavities of Old World primates.…”
The lung mite P. africanus Fain, 1959 and its larva from a new host (Mandrillus leucophaeus) is described and compared to the most frequently found species, P. simicola Banks, 1901. The chaetotaxy of the legs is essentially identical, but leg IV of P. simicola bears 5 spines and10 setae, while in P. africanus one of the spines is replaced by a seta. Also, very fragile small setae were discovered at the base of the ambulacra on legs II, III and IV in P. africanus and only on leg IV in P. simicola. The chaetae of the 'Haller's organ' on leg I are described in detail, and formulae for the chaetotaxy of all legs and measurements of both species are given.

“…Also, there has been one species of lung mite in the genus Pneumonyssoides that has been reported from the lungs, larynx, nasal cavities, and sinuses in New World monkeys (woolly monkeys and howler monkeys) [254,290,405,413,742,871].…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
