Doesn't EXIST things like INSECTIVORA, Lipotyphla nor Eulipotyphla as little! The ZALAMBDODONTA and Erinaceoidea are monophyletic GROUPs.

It is very, very CLEAR ! Can't you SEE ? IF NOT ! So...it's better to accept !

LINK To all that want to understantand these monophylies and all about the new classification of Mammalia !

Erinacoidea (an illustration to the beginners)

 I propose Caecoidea  as sister group of Erinacoidea .  As that group is characterized mainly by presenting a "caecum" developed. Caecoidea comprises the Tubulidentata, Glires, Macroscelidea and Paenungulata. I didn't like this name, but we need a reference. I will think in something better.
