  Spalacidae - Wikipedia, the free encyclopedia
Spalacidae is a family of rodents in the large and complex superfamily Muroidea.
It was thought that these rodents evolved adaptations to living underground independently until recent genetic studies demonstrated that they form a monophyletic group.
Members of the Spalacidae are often placed in the family Muridae along with all other members of the Muroidea.

In the skull the zygomatic arch is slender and the fugal bone small and not extending far forwards, being supported by the long zygomatic process of the maxilla, while the infra-orbital foramen is mostly FIG.
The Spalacidae are burrowing types, allied apparently to the ancestral Jaculidae, and characterized by the second and third molars being equal in size, the presence of enamel-folds in all these teeth, and the superiority in size of the claws of the second, third and fourth front toes over the other two.
Strand-Moles.—With the so-called strand-moles of South Africa, forming the section Bathyergoidea, and the family Bathyergidae, which were formerly placed with the Spalacidae, we come to the first of two sections in which the lower jaw has a totally different form to that obtaining in all the preceding groups.

We concluded that the taxonomy of Spalacidae needs a modern revision based on chromosome and molecular-genetic data, beside that of morphology, physiology and behavior.
The subterranean Spalacidae originated probably from a muroid-cricetoid stock in Asia Minor or vicinity, in Upper Oligocene times and adaptively radiated underground in the Balkans, steppic Russia and Middle East, extending into North Africa.
A short overview is presented on population biology and life history parameters of the Spalacidae which result in K-selected, "equilibrium species".

The family Spalacidae consists of 36 species of mole rats, zokors, and bamboo rats.
This diverse group of fossorial rodents can be found throughout much of the old world from the Ukraine through the Balkans and the eastern Mediterranean, into Africa as far west as Libya and as far south as northern Tanzania, and in Asia from western China south to Sumatra and north to southern Siberia.
All members of the Spalacidae belong to the Rodentia

Based on our analyses, Myospalax appears to be sister to a clade containing the subfamilies Spalacinae and Rhizomyinae, and all three of these lineages appear to be basal to the superfamily Muroidea.
Based on the position of these three lineages, we suggest that they be placed in a distinct family, the Spalacidae, rather than subsumed as subfamilies in the family Muridae.
Finally, our analyses suggest that the earlier placement of Myospalax as a member of the Cricetinae is the result of a single misidentified specimen, which was not a Myospalax.

This is the only subfamily of muroids that has not been included in a molecular phylogenetic study.
They can be distinguished from both the family Spalacidae and the Eumuroida (all non-spalacid and non-platacanthomyine muroids) by the distinct shape of their infraorbital canal and by the presence of multiple openings in the palate of the skull.
On the basis of these two characters, they have been considered to be distinct from all other muroids.

The term Cricetidae has gone through several permutations, and members of the family as currently defined are often placed in the family Muridae along with all other muroid subfamilies.
Many other muroids have been called members of the Cricetidae in the past such as mouse-like hamsters (subfamily Calomyscinae, family Calomyscidae), gerbils (subfamily Gerbillinae, family Muridae), the crested rat (subfamily Lophiomyinae, family Muridae), zokors (subfamily Myospalacinae, family Spalacidae), the white-tailed rat (subfamily Mystromyinae, family Nesomyidae), and spiny dormice (subfamily Platacanthomyinae, family Platacanthomyidae).
Genetic studies have shown that the subfamilies listed below are related (form a monophyletic group), and that these other animals should not be included in the Cricetidae.

In the mouse genome, the 4.5SH RNA gene is a part of a long (4.2 kb) tandem repeat (
Here, we found that 4.5SH RNA genes are present only in rodents of six families that comprise the Myodonta clade: Muridae, Cricetidae, Spalacidae, Rhizomyidae, Zapodidae, and Dipodidae.
The analysis of complementary DNA derived from the rodents of these families showed general evolutionary conservation of 4.5SH RNA and some intraspecific heterogeneity of these RNA molecules.
