[1] The first specimens were found from the Danata Formation Lagerstätten, of the Ypresian age of Turkmenistan, where they were originally thought to be smaller or juvenile individuals of the true louvar, Luvarus necopinatus.

These specimens were later reexamined, and determined to be a separate genus comprising two species.

[3] Indeterminate remains are also known from the Ypresian Gerpegezh locality in Russia.
