Material (fossil specimens) 9 specimens: Messinian ( Bollmannia cf. ocellata ): Pacific Panama, Chucunaque FM , 1 specimen PPP 1576 , 1 specimen PPP 1578 (figured specimen NMB P15477 View Materials ) . Calabrian : Pacific Panama, Armueles FM , 6 specimens PPP 3235 (figured specimen NMB P15478 View Materials ) ; 1 specimen PPP 3236 (figured specimen NMB P15476 View Materials ) .

Discussion Otoliths of B. ocellata resemble those of B. boqueronensis described above but differ in a few subtle characters: a more strongly and regularly crenulated dorsal rim, the slightly projecting preventral angle and the caudal tip being slightly bent upward, a feature commonly observed in a number of Bollmannia species. Te otoliths of B. ocellata also resemble those of B. marginalis ( Fig. 15k View Fig ), but differ in the more intense crenulation of the dorsal rim and the slightly upward bent caudal tip.

Te two figured specimens from the Calabrian of Armuelles ( Fig. 15n–o View Fig ) are well preserved but small (OL = 1.5 mm), probably from juveniles. Te single large specimen from the Messinian of Darien ( Fig. 15p View Fig ) is rather poorly preserved and therefore only tentatively allocated.

Bollmannia ocellata today is found from the Gulf of California to Ecuador at depths of 10–120 m on muddy bottoms ( Froese & Pauly, 2023).
