The subfamily Rhizomyinae is known from the Late Oligocene up to the present. Today this group comprises six species, which live in southern Asia and eastern Africa. Despite the current moderate diversity of the rhizomyines, they had a greater diversification and wider distribution in the past: from Asia, their land of origin, to Africa, which they entered during the Early Miocene. So far 33 fossil species can be referred to this group. A cladistic analysis involving fossil and living species has been carried out. Prokanisamys spp. turned out to be the most basal taxa of the ingroup. This analysis calls into question the monophyly of several genera, and allows the proposal of a phylogenetic definition of the tribes Tachyoryctini and Rhizomyini. It also provides information about the origin of the African rhizomyines and allows inferring multiple dispersal phenomena from Asia to Africa in Early and Late Miocene times.
竹鼠亚科已知存在于晚渐新世至今。如今，该类群包括六个物种，分布于亚洲南部和非洲东部。尽管目前竹鼠类的多样性适中，但它们在过去具有更高的多样性和更广泛的分布：从其起源地亚洲，到在中新世早期进入的非洲。到目前为止，有33个化石物种可归入该类群。已经对化石和现存物种进行了支序分析。原卡尼鼠属被证明是内群中最基部的分类单元。该分析对几个属的单系性提出了质疑，并允许对速掘鼠族和竹鼠族进行系统发育定义。它还提供了有关非洲竹鼠类起源的信息，并允许推断在中新世早期和晚期从亚洲到非洲的多次扩散现象。
