Hanakia aff. antiquus ( GAILLARD, 1899)

Text-fig. 3j–k

M a t e r i a l a n d m e a s u r e m e n t s. Erkertshofen 1: BSP 1962 XIX 4196, left M2, 1.60 × 2.10

Petersbuch 2: PCMRCh1, left M2, ≈1.50 × ≈2.00; PCMRCh2, left M1, 1.60 × 1.95; PCMRCh3, left M1, 1.40 × 1.70.

D e s c r i p t i o n a n d c o m p a r i s o n. These fossils from Petersbuch 2, Erkertshofen 1 and Erkertshofen 2 ( Text-fig. 3 ) morphologically correspond to H. agadjaniani , but are noticeably smaller in size ( Tab. 6). Moreover, the trigon basin of the upper molar (specimen PCMRCh2) from Petersbuch 2 is closed ( Text-fig. 3J ), similar to Eptesicus aurelianensis from Stubersheim 3 ( Ziegler 1994: 113, fig. 6), which is significantly smaller in size (compare with Ziegler 1994: 112). This specimen from Petersbuch 2 morphologically is closest to H. aff. antiquus ( Tab. 6; compare with specimen Mer91C43, Horáček 2001: 133, fig. 14). Another fossil upper molar (specimen PCMRCh1) differs from E. aurelianensis in being larger and in having an open trigon basin without metaloph ( Text-fig. 3K ; compare with Ziegler 1994: 113, fig. 6). The studied upper molars differ from those of the species of H. antiquus from La Grive 7 in lacking the para- and metalophs (compare with Baudelot 1972: 50, tab. 2).
