Tragulina (also known as Traguliformes) is an infraorder of even-toed ungulates. Only the chevrotains survive to the present, including the genera Tragulus (the mouse deer) and Hyemoschus, all within the family Tragulidae.

Taxonomy and Classification[]

Leptomeryx

Tragulina is an infraorder within the larger suborder Ruminantia, and is the sister clade to the infraorder Pecora. Tragulina contains one extant (living) family, Tragulidae, as well as several extinct families, although the extinct members currently classified as within Tragulina causes it to be considered paraphyletic.^[2]

Tragulina's placement within Artiodactyla can be represented in the following cladogram:^[3]^[4]^[5]^[6]^[7]

Artiodactyla

Tylopoda (camels)

Artiofabula

Suina (pigs)

Cetruminantia

Ruminantia (ruminants)

Tragulina	Tragulidae (mouse deer)

	Pecora (horn bearers)

Cetancodonta/Whippomorpha

	Hippopotamidae (hippopotamuses)

	Cetacea (whales)
