Geodorcus sororum (Holloway, 2007)[2]
|
Geodorcus sororum is a large flightless species of stag beetle in the family Lucanidae. It was discovered in 1973 by Mr. A. Wright on an expedition to Middle Sister Island, one of The Sisters Islands which are part of the Chatham Islands in New Zealand.[2] This holotype specimen is held in the New Zealand Arthropod Collection.[3] It was first described by Beverley Holloway in 2007.[2] The name sororum is translated from latin to mean "belonging to the sisters".[2]
Description
This beetle ranges in length (including mandibles) from 18.0 to 28.5 mm (males) and from 19.4 to 24 mm (females). It has a glossy exoskeleton which ranges in colour from reddish-black to black. Like Geodorcus servandus, its elytra are not distinctly ribbed. This is a feature that distinguishes G. sororum from G. capito which is also found in the Chatham Islands. They demonstrate sexual dimorphism with an overall size difference and obvious differences in mandible shape and size.[2]
