Type material – Holotype: right mandible fragment with P 4 -M 3 and skull processes except angular process (ZZSiD, No. MF/1513). I 1, left and right maxillary fragment with M 1 and M 2, left mandible fragment with M 1 and skull processes except the angular process, and 9 right mandible fragments, partly with skull processes except the angular process and all together providing a full set of the lower teeth except I 1 ( RZEBIK-KOWALSKA 1976).
Type locality – Rębielice Królewskie 1A, Poland, Upper Pliocene ( MN 16 , Lower Villafranchian Stage) .
Studied material – Somssich Hill 2 locality: 1 right maxillary fragment, 1 left mandible fragment, 5 right mandible fragments, 1 right P 4, 1 left M 1, 1 right I 1 and 1 right M 2.
Measurements – Table 2.
Dental formula – 153/123.
Original diagnosis – The morphological structure of B. minor is an exact counterpart of the structure of B. fissidens , in connection with which its classification in the genus Beremendia does not rouse doubt. However, the dimensions of this species are much smaller than those of the members of B. fissidens from the same locality and the smallest specimens from the Pliocene locality at Węże I. As the difference in size is conspicuous, the dimensions of the two forms do not overlap, and they occur in the same locality, the small form has been included in a separate species (after RZEBIK-KOWALSKA 1976).
Emended diagnosis – According to REUMER (1984) B. minor is morphologically identical to B. fissidens . The two species differ only in size, B. minor is considerably smaller than B. fissidens .
Anatomical description – The dimensions of the species are significantly smaller than those of B. fissidens (not only the dental elements but also the size of the mental foramen, its anterior basin and the parameters of the symphysis fossa). I 1 – The angle of I 1 is smaller between the ventral part of the apex and the anterior margin of the talon. I 1 – It has a more pointed apex and a more curved lower incisor. M 3 – B. minor has a high entoconid, a rounded hypolophid and the posterior margin of the talonid is round ( Figs 13–15 View Figs 13–14 View Figs 15–16 ).
Remarks – The occurrence of the small form of Beremendia is also mentioned by FEJFAR (1964) from Hajnačka ( Slovakia), which corresponds in age with Rębielice Królewskie. FEJFAR described them as Beremendia sp. According to RZEBIK-KOWALSKA (1976) Beremendia fissidens remains from Schernfeld ( Austria) ( DEHM 1962) and the Beremendia sp. from Hajnačka ( FEJFAR 1964) seems to be as small as B. minor in dimensions. The measurements of the small form of Beremendia from the Somssich Hill 2 locality compounds with the aforementioned remains ( DEHM 1962; FEJFAR 1964).
