Remarks: The genus Androlaelaps   s.l. is problematical and unsettled taxonomically. Historically, a wide range of morphologically variable mite populations have been identified under the names A. fahrenholzi   and Androlaelaps glasgowi (Ewing)   . Furman (1966) placed A. glasgowi   in synonymy with A. fahrenholzi   , so for the purposes of this paper we have chosen to continue using this epithet for these mites, even though they occur on multiple host species around CPBS. More research is needed to assess whether this species is truly polyxenous, or a composite of more host specific, but cryptic species. In just two collecting periods, we have collected A. fahrenholzi   from nine different genera of hosts ( Sorex   , Onychomys   , Peromyscus   , Reithrodontomys   , Microtus   , Zapus   , Chaetodipus   , Dipodomys   , and Perognathus   ). Rapp (1962) recorded the occurrence of A. glasgowi   on several species of small mammal hosts in Nebraska, and noted that the “specimens show intraspecific variations depending upon their host”.
