Material 1 specimen Calabrian , Armuelles FM , Pacific Panama, PPP 3236 ( NMB P15737 View Materials ) .

Discussion A single, 1.45 mm long and relatively well-preserved specimen from the middle Pleistocene of Pacific Panama is characterized by a regularly crenulated otolith rim, a small and narrow sulcus with a very low ostial lobe and a massive subcaudal iugum ingressing into the cauda from ventral and posterior. Te ratio OL:OH is 0.85; the ratio OL:SuL = 2.2. Tere is a good chance that this otolith belongs to one of the four extant Microgobius species from the East Pacific from which otoliths are not yet known. Tis would also mean that the Microgobius camur otolith plexus, which apparently is extinct in the West Atlantic could have survived in the East Pacific.
