while in exilis it is more or less a rectangle. The protoconid area of the is better developed and the trigonid is relatively wider in exilis

. Mg with talonid narrower than in exilis. Myotis paradaubentoni sp. n. Derivatio nominis

: The name of this new species refers to its relation with Myotis daubentoni (Kuhl, 1819). Stratum typicum and locus typicus

: Estramontian horizon of the Middle Pliocene, Osztramos Locality 13, NE Hungary. Diagnosis

: A small Myotis related to M. daubentoni

, with wider interorbital constriction and narial notch, stronger canines, more progressed, shorter premolar rows and shorter M
