Agrotis ceropachoides Guenée, 1868
Taxonomy & Nomenclature
Synonym/s: Euxoa ceropachoides Guenée, 1868; Euxoa cerapachoides Guenée, 1868 [orth. error used by Pawson & Emberson, 2000]
Last record: early 1860's (Patrick, 2014)
Rediscovered: 4 July 2012 (Patrick, 2014)
Previously thought to have disappeared after only a single record:
"Another likely candidate for extinction is “Euxoa” ceropachoides (Noctuidae), which has not been definitely collected since it was described in 1868; its Canterbury lowland habitat is much altered; however, it may conceivably have been overlooked amongst populations of the variable and very similar “E.” admirationis."
(Stringer et al., 2012:124)
But later records have since been retrospectively established thanks to its rediscovery (Patrick, 2014:31):
"Richard Fereday died in 1899, and no more captures of this moth under the correct name appear to have been made until the author (BP) rediscovered it on 4 July 2012. As stated above, part of the reason for that is that the holotype is a dull grey colour morph which is not typical for the species, and this was also the variety of the species illustrated by Hudson (1898). We now know that this variety makes up less than 10% of males."
Mid Canterbury, South Island, New Zealand
"it is clear from Hudson (1898) that Fereday discovered the species at Rakaia, and as this is the only locality noted, it must stand as the type locality... The type locality can be further defined as the Oakleigh Station farm of Fereday’s brother. The type locality should be noted as: “Oakleigh Station, Rakaia River mouth”, as Oakley Farm is still shown on current maps and has a close connection to both Fereday Island and Rakaia Island, where natural vegetation still exists."
