We present the first results of a detailed comparison between the pulsation properties of pulsating Extremely Low-Mass pre-white dwarf stars (the pre-ELMV variable stars) and $delta$ Scuti stars. The instability domains of these very different kinds of stars nearly overlap in the $log T_{m eff}$ vs. $log g$ diagram, leading to a degeneracy in the classification of the stars. Our aim is to provide asteroseismic tools for their correct classification.
