Ailuridae

Ailuridae is a family in the mammal order Carnivora. The family consists of the red panda and its extinct relatives.

Classification
The relationship of the Ailuridae with other carnivorans is shown in the following phylogenetic tree, which is based on the molecular phylogenetic analysis of six genes in Flynn (2005), with the musteloids updated following the multigene analysis of Law et al. (2018). In addition to Ailurus, the family Ailuridae includes seven extinct genera, most of which are assigned to three subfamilies: Amphictinae, Simocyoninae, and Ailurinae. • Family Ailuridae J.E.

Taxonomic history
The species Ailurus fulgens was described by George Cuvier in 1825. In 1843, J.E. Gray assigned Ailurus fulgens to the new subfamily Ailurinae. In 1853, Pomel described the new genus Amphictis for "Viverra" antiqua. In 1858 the genus Simocyon was described. The subfamily Simocyoninae was named in 1868 for the genus Simocyon In 1899 the genus Parailurus was named. In 1940 the new genus Alopecocyon was described. In 1947 the new genus Actiocyon was described. In 1976 the new genus Protursus was described. In 1997 the new genus Magerictis was described. An additional, unnamed taxon called only "Ailurinae indet." was described in 2001 based on an upper molar from Four, a Middle Miocene-age locality near Isère, France. In 2004 the genus Pristinailurus was named. The new genera Bonisictis and Rothictis were described in 2025, both for species previously assigned to Amphictis. That genus along with Bonictis were assigned to the ressurected family Amphictidae, while Rothictis and Magerictis were assigned to the new ailurid subfamily Magerictinae. ==References==
