The Afroinsectiphilia (African
polyphyletic and obsolete. This proposed classification is based on molecular studies only, and there is no morphological evidence for it.[2]
The
otter shrews and tenrecs are part of this clade. Some also regard the elephant shrews and aardvarks as part of it, although these two orders were traditionally seen as primitive ungulates. The sister group of the Afroinsectiphilia is the Paenungulata
, which were also traditionally regarded as ungulates.
If the clade of Afrotheria is genuine, then the Afroinsectiphilia are the closest relatives of the
ungulates
, thus not related to Afroinsectiphilia. However, DNA research is thought to provide a more fundamental classification.
Additionally, there might be some dental synapomorphies uniting afroinsectiphilians: p4 talonid and trigonid of similar breadth, a prominent p4 hypoconid, presence of a P4 metacone and absence of parastyles on M1–2. Additional features uniting
tubulidentates specifically include hypsodont molars that wear down to a flat surface; a long and shallow mandible with an elongated symphyseal region; and trigonids and talonids that are separated by lateral constrictions.[3][4]
