Hadramphus pittospori is a species of large molytine weevil in the family Curculionidae.[1] It is endemic to the Poor Knights Islands of New Zealand.[1][2] Under the New Zealand Threat Classification System, this species is listed as "Naturally Uncommon" with the qualifiers of "Island Endemic" and "Range Restricted".[3]
This species was first described by Guillermo Kuschel as Karocolens pittospori in 1987.[4][2] In 1999 it was redescribed by Robin Charles Craw and moved to genus Hadramphus.[5]
The holotype specimen was found in the Poor Knights Islands and is stored in the New Zealand Arthropod Collection.[2][5]

Description
Both larvae and adults of Hadramphus pittospori are flightless and brown in colour.[1][6] Adults are unusually long-lived for weevils and can survive for over 3 years when raised in captivity.[2][6] They can reach lengths of 16.5-19.7 mm.[5] The larvae can get up to 22 mm long.[1] Larvae development consists of six instars, unlike most weevil species which have only three.[6]
