Pipistrellus cinnamomeus Miller 1902 Referred to the Genus Myotis

"Pipistrellus cinnamomeus Miller 1902 Referred to the Genus Myotis by Hall et al." by E. Raymond Hall and Walter W. Dalquest is a scientific publication written in the mid-20th century. This text discusses the taxonomic classification and detailed examination of a particular species of bat, specifically "Pipistrellus cinnamomeus", and its reassignment to the genus "Myotis". The work highlights the anatomical and morphological comparisons that led to the taxonomic changes and provides a comprehensive account of the bat specimens examined. The book primarily details the history surrounding the naming of "Pipistrellus cinnamomeus", including the original description by G. S. Miller in 1902, based on limited specimens collected in Mexico. It elaborates on additional specimens discovered later which contributed to a better understanding of this bat species. Key distinguishing features from other related species—such as the presence of two premolars instead of three—are detailed. The authors ultimately argue for the reclassification of "Pipistrellus cinnamomeus" as "Myotis fortidens", analyzing its geographical distribution and notable physical characteristics, while emphasizing the need for further research to understand the relationship between various "Myotis" species comprehensively.
