Material examined. Holotype male, allotype female and three paratype females ex Mimetillus moloneyi, La Maboki, Republic of Central Africa, 1965, in the collection of MNHN; a male paratype ex M. moloneyi, Bo, Sierra Leone, date uncertain (BM ); and a female paratype ex M. moloneyi, date uncertain (BM ). The holotype and allotype are deposited in the collection of the MNHN; a pair of male and female paratypes is in the collection of the BMNH (BM ); and three para- type females are in the collection of the author. Diagnosis. Among the known species of the genus Pteracarus, P. charinolobus (Womersley), P. microdorsalis Fain & Lukoschus and the preceding species, P. pipistrellius (Radford), are characterized by lacking d5 dorsally on the female idiosoma. Pteracarus mimetillius sp. nov. is easily differentiated from the above three species by its unique setae on the idiosomal venter. Thick, relatively short and apically bifurcated setae ve, sc e and /t of both sexes are also characteristic of the new Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Farn, Alexander E.
