Deto aucklandiae is a species of seashore dwelling woodlouse from the Detonidae family.[1] D. aucklandiae is endemic to a few subantarctic islands in New Zealand.
Deto aucklandiae was first described in 1879 as Actaecia aucklandiae.[2] In 1906, D. aucklandiae was described again as Deto magnifica and Deto robusta.[3] A. aucklandiae was then moved to the Deto genus in 2003 and D. magnifica and D. robusta were recognized as synonyms.
Deto aucklandiae are a large, sexually dimorphic species, with males reaching 20-24mm in length and females reaching 12-19mm in length. Males have large, thick antennae and a dorsal surface that is covered in spine like tubercles. Females have more slender antennae than the males and can also be distinguished by a slight groove present in segments 2, 3 and 4.
Deto aucklandiae occurs in the coastal zone of subantarctic islands in New Zealand.[4] They are known to occur on Auckland Island, Campbell Island and Snares Island.
