Deomyinae

Deomyinae is a subfamily within the rodent family Muridae that includes several African genera commonly referred to as spiny mice and their relatives. The group is defined largely by molecular phylogenetic studies, and its circumscription has varied among authorities. In contemporary classifications, Deomyinae typically comprises genera such as Acomys (spiny mice) and a clade that includes Lophuromys (brush-furred mice) and Deomys, representing two principal lineages within the subfamily.

Genera and distribution characteristic of Deomyinae are largely restricted to sub-Saharan Africa. Members occupy a wide range of habitats, from dry savannas and rocky outcrops to forest edges and montane regions. Spiny mice of genus Acomys are notable for their spiny fur, which provides protection from predators and harsh environments. Lophuromys species are characterized by dense, bristly fur and, in some cases, robust dentition. Deomys includes smaller, forest-associated species about which less is widely known.

Ecology and biology within Deomyinae are diverse: species are generally nocturnal and omnivorous, feeding on seeds, fruits, and invertebrates. Reproductive strategies vary among species, with litter sizes and breeding seasons influenced by environmental conditions. Behavior ranges from relatively sedentary to more exploratory, depending on habitat and resource availability.

Evolution and taxonomy within Deomyinae reflect ongoing revisions as molecular data refine murid relationships. The subfamily is viewed as a distinct lineage within Muridae by many researchers, though its internal grouping and the placement of certain genera have been subject to change. Conservation status across the subfamily ranges from common to threatened, with habitat loss and fragmentation being primary concerns for some species.
