alleghaniensis

alleghaniensis is a Latin adjectival suffix often used in scientific nomenclature, particularly for species, to denote origin or association with the Allegheny Mountains or the Allegheny Plateau region of North America. When encountered in a scientific name, such as *Geomys alleghaniensis* or *Ambystoma alleghaniensis*, it indicates that the organism was first described from, or is characteristic of, this specific geographical area.

The Allegheny Mountains form a prominent ridge-and-valley physiographic province of the Appalachian Mountains. This region stretches across several eastern states of the United States, including Pennsylvania, West Virginia, Maryland, Virginia, and New York. The extensive range of habitats within this area, from forested slopes to river valleys, has supported a diverse array of flora and fauna, leading to the naming of many species with the alleghaniensis epithet.

Examples of scientific names incorporating alleghaniensis can be found across various biological taxa. These include mammals like the Allegheny woodrat (*Neotoma alleghaniensis*), amphibians such as the Allegheny salamander (*Ambystoma alleghaniensis*), and various plant species. The use of this suffix is a convention that aids taxonomists and ecologists in understanding the distribution and evolutionary history of species. It serves as a direct link between the organism's scientific designation and its geographical home.
