Helenomelas basilewskyi Ardoin

Basilewsky’s Darkling Beetle (Helenomelas basilewskyi)

This species is/was endmic to the island of Saint Helena in the southern Atlantic Ocean, where it was apparently restricted to the Prosperous Bay Plain at the eastern coast of the island.

The quite large species reaches a length of about 1,5 cm and is shiny black colored, it superficially resembles scarabeid beetles (Scarabeidae).

Basilewsky’s Darkling Beetle was not found during recent searches in 2003 and is feared to be extinct. [1]
