First record of Ammocrypta pellucida (Agassiz, 1863) (Actinopterygii: Perciformes) from the Lake Ontario drainage basin

The objective of this paper is to document the first occurrence of Ammocrypta pellucida in the Lake Ontario basin from samples collected in West Lake, Ontario (Canada) in 2013. Prior to this record, the known range of this imperilled species consisted of two disjunct elements in eastern North America separated by about 500 km. The new occurrence is in the middle of these two distributional elements and suggests that further inventory efforts are warranted in the intervening area.
