T y p e s p e c i e s: <i>Phoca sarmatica</i> Alekseev, 1924 (pl. 1, <i>1&amp;Acy;, 1B</i>). Holotype from Kishinev, Moldova, Eastern Europe (Alekseev, 1924), Middle Miocene, middle Sarmatian. S t r a t i g r a p h i c a l r a n g e. Aside from the type locality the genus is also known from the late Miocene (early-middle Tortonian, 8.0–11.5 ma) of Denmark, northern Europe. I n c l u d e d s p e c i e s. Until now, only the type species was included in this genus. Here, we introduce a second species, <i>Pontophoca jutlandica</i> Koretsky et al., sp. n. R e f e r r e d m a t e r i a l. Mandible, scapula, tibiae and fibulae, femora, humeri, innominates (Koretsky, Grigorescu, 2002). E m e n d e d d i a g n o s i s. Lower premolars p1 and p2 double-rooted, placed parallel to tooth row axis; protoconid on p2 triangular; diastemata present; metaconid and basal cingulum weakly developed. Deltoid crest of humerus terminates in middle of diaphysis, its proximal part averted in dorsal direction; distal epiphysis considerably inflated compared to proximal epiphysis; lesser tubercle located higher than proximal end of deltoid crest and head; index of head’s height (ratio of head width/head height) near 100 %; supracondylar crest strongly developed. Height of femoral greater trochanter slightly exceeds that of head; its distal end narrower than its proximal end; head very small compared with the otherwise massive bone and seated on narrow neck; minimal width of diaphysis located in proximal part of bone between neck and distal part of greater trochanter; distal end of femur 1.4– 1.5 times broader than proximal end; condyles widely separated; maximal distance between epicondyles about or more than 70 % of bone’s length.
