Hypertragulus hesperius

Mammalia - Hypertragulidae

Taxonomy
Hypertragulus hesperius was named by Hay (1902) [No type specimen was originally designated for Hypertragulus hesperius (Hay, 1902), but Lull (1922) states that in a conversation he had with William D. Matthew that AMNH 7918, figured by Cope and Scott (specific references not cited in Lull 1922), is to be regarded as the type, and Lull did include additional characters for the species. AMNH 7918 was not formally designated as a type (Hay 1902) nor a lectotype by Lull (1922), but Famoso and Jewell (2024) stated that it should be recognized as the lectotype as per ICZN article 74.5.].
