: Myotis paradaubentoni sp. n. is related to M. daubentoni of the recent faunas. Its full skull and braincase are not known, though, a few available rostra and other fragments show well a number of important characters to separate this new species from the recent one and other small Myotis found in the Middle Pliocene faunas, respectively. The rostrum is similarly stout, but even wider than taht of the recent daubentoni

. Interorbital constriction is wider in the fossil, orbital ridges are markedly stronger. Narial notch is wider in the new species, and the anterior palatal emargination is shallower in the fossil animal too. It does not reach the level of half length while in the recent species it extends to the level of posterior border of C alveoli. Incisivi of paradaubentoni sp. n. are generally greater and its canines usually bulkier; their cross-section area being greater by one-third. The one-rooted premolars stand tightened in the fossil species, though of the same size as in daubentoni

. The P

4 fossil tends to be shortened antero-posteriorly and its antero-internal cusp invariably incipient or even missing. Due to the above features the anterior portion of toothrow - although consisting of greater teeth - relatively or even absolutely more shortened than in daubentoni

. The fossil M and M

2 are but in some cases greater, M is actually always shorter anteroposteriorly and wider too. These abovementioned important differences, that is, the shortened C-P

4 length and the shortened M

3 length, suggest the existence of two separate evolutionary lines. So, one cannot consider M. paradaubentoni sp. n. as an ancestor to the present species: the former being more advanced and the latter is comparatively primitive in many characters. As compared with M. exilis

, the new species definitely differs in the much wider interorbital constriction and in the great, wider anterior palatal emargination. M. paradaubentoni sp. n. shows the maximum values of rostral width at C-C and M

3-m"

7 though there are overlaps between the two species. In M

3 length, paradaubentoni sp. n. has the smallest values with almost no overlap. Their mandibles are different in the height of coronoid process: paradaubentoni sp. n. has shorter and lower coronoid, then' in the extent of tightness and size of small premolars - paradaubentoni sp. n. has smaller and more compressed P

, P3. Ij and I

2 each has definitely 3 cusps in paradaubentoni sp. n. Lower C is

1 strong, with crown great and narrower than in exilis

. Mg is with wide talonid. A comparison with _M. janossyi sp. n. shows the interorbital constriction of paradaubentoni sp. n. being decidely greater and so are the values in rostral width. Its narial notch is broader and U-shaped, the anteorbital bridge much shorter than that of janossyi sp. n. Anterior palatal emargination is wide and not so rounded as in the other species, though in both extends similarly up to about half length level of C alveoli, or less. P

2 and P

3 are greater in janossyi

, reversely, P is smaller and with stronger antero-internal cusp as compared to those of paradaubentoni sp. n. M* and M

2 are greater and wider
