INV 2014.105. 11.1 11.3 6.5 1.8 Remarks – This is a rarely illustrated species, which was previously known only from the Central Appennines. Now it seems that H. meneghinii is rather frequent in Turkey: besides the present record, it was mentioned by VADÁSZ (1918) and documented in details by Vörös (2014). The author examined the original material of ZITTEL (1869) in the Bayerische Staatssammlung (München) and confirmed that the tiny “ Rhynchonella ” meneghinii is characterized by subtriangular outline, faint ribs which develop just near the anterior margin and a shallow dorsal sulcus; the anterior margin is only slightly sulcate. On these grounds our specimens from Yakacik can definitely be identified with Holcorhynchia meneghinii . AGER (1959 a) described a closely related species, H. yakacikensis Ager, 1959 from Yakacik, which is, however, significantly more elongated than meneghinii . H. meneghinii was recorded from the Pliensbachian of the Central Appennines and Turkey.
