Texanus

Texanus is a Latinized descriptor often used in scientific nomenclature to indicate an origin or association with the state of Texas in the United States. This suffix is commonly applied to species of plants, animals, and other organisms that are native to or have been historically found within the geographical boundaries of Texas. For example, it might appear in the scientific name of a particular subspecies of lizard or a variety of wildflower.

The use of "texanus" in taxonomy serves to precisely identify the geographical distribution of a species or subspecies. It helps distinguish between populations that may be morphologically similar but geographically separated, thus contributing to a better understanding of biodiversity and evolutionary relationships. Researchers often employ this designation when describing new species discovered in Texas or when reclassifying existing ones based on new genetic or morphological data. Its presence in a scientific name provides a clear indicator of the organism's connection to the Texan ecosystem.
