Tathorhynchus

Tathorhynchus is a monotypic moth genus in the family Erebidae erected by George Hampson in 1894.[1] Its only species, Tathorhynchus exsiccata, the Levant blackneck or double-spotted snout, was first described by Julius Lederer in 1855. The nominate form is found on the Canary Islands and in North Africa, tropical Asia and tropical Africa. It has been introduced in Dominica and Argentina. Subspecies Tathorhynchus exsiccata fallax is found in the northern half of Australia, as well as Norfolk Island and New Zealand.
