Cynarctoides harlowi is an extinct species of Cynarctoides, belonging to the subfamily Borophaginae and tribe Phlaocyonini, a canid which inhabited west central North America during the Late Oligocene to Miocene epoch living 24.8—20.6 mya and existed for approximately 4.2 million years.

Taxonomy

Cynarctoides harlowi was originally named Pachycynodon harlowi by Loomis (1932). Its type locality is Van Tassel (Upper), which is in a Harrisonian terrestrial horizon in Wyoming. It was recombined as Nothocyon harlowi by Macdonald (1963); it was recombined as Cynarctoides harlowi by Xiaoming Wang, Richard H. Tedford et al. (1999).^[1][2]
