Temporal range: Middle Eocene–Middle Miocene
|Range of Leptomerycinae based on fossil record|
Leptomerycinae is an extinct subfamily within the ruminant family Leptomerycidae. It contains three genera, Leptomeryx, Pronodens, and Pseudoparablastomeryx, which lived in North America during the Middle Eocene to Middle Miocene. Leptomeryx may also have occurred in Asia during the Early Oligocene. The subfamily was first named by Zittel in 1893.
Leptomerycinae was named by Zittel (1893). It was reranked as the subfamily Leptomerycinae by Matthew (1908). It was assigned to Hypertragulidae by Matthew (1908); and to Traguloidea by Carroll (1988).
