Antipterna ptychomochla is a species of moth in the family Oecophoridae, first described by Alfred Jefferis Turner in 1940 as Antiterpna ptychomochla (sic).[1] [2] The species epithet derives from the Greek, πτυκομοχλοσ, meaning "with bar on fold".[2]
It appears to be a moth endemic to Australia and found in South Australia and New South Wales, with occurrences near the confluence of the Murray and the Darling rivers.[3] Turner described specimens from Merredin in Western Australia.[2]
