Sminthidae is a family of mouse-like jumping rodents. They are represented by two extant genus, Sicista and Breviforamen[1], represented by 24 species found throughout most of Eurasia, from central Europe east to Siberia, and south to southern China. However, they were much more diverse and had a much wider range in prehistory, having multiple genera and being found not only in Eurasia but also throughout North America, where they existed up to the early Pleistocene. They have a well-attested fossil record which dates as far back as the early Oligocene.[2]

They were formerly classified as the subfamily Sicistinae in the family Dipodidae alongside the jerboas and jumping mice, but phylogenetic evidence supports all three of these belonging to distinct families, thus leaving only the jerboas in Dipodidae.[3]

Extinct genera
editThese extinct genera are definitively known:[2][5][6]
- Genus †Allosminthus
- Genus †Heosminthus
- Genus †Heterosminthus
- Genus †Gobiosminthus
- Genus †Lophocricetus
- Genus †Macrognathomys
- Genus †Megasminthus
- Genus †Miosicista

- Genus †Plesiosminthus
- Genus †Schaubemys
- Genus †Shamosminthus
- Genus †Sinosminthus
- Genus †Tyrannomys
The Eocene genera Primisminthus and Banyuesminthus could represent even older members of Sminthidae, although other studies speculate that they may be basal dipodoids.[2]
