The genus Cryptotis is a group of relatively small shrews with short ears which are usually not visible and short tails.
They are found mainly in Central America; the North American Least Shrew, C. parva, is the only species of the genus found north of Mexico. The genus occurs as far south as northern Peru and as far east as western Venezuela in South America. It is the only soricomorph genus found south of Guatemala. They are red-toothed shrews; species in this group have 30 teeth. Since 1992, Neal Woodman (in corporation with Robert Timm) at the United States National Museum has been in the process of revising the genus. To date, this has resulted in an increase of number of species from 12 in 1992 to 30 now.
