Burney’s Blackburnia Ground Beetle (Blackburnia burneyi)

Burney’s Blackburnia Ground Beetle was described in 2015, it is known only from subfossil elytra that had been recovered from sediments from the Makauwahi Cave on the island of Kaua’i, Hawaiian Islands.

The species is thought to have been macropterous.

Burney’s Blackburnia Ground Beetle apparently was a lowland species and thus was among the first invertebrates to be wiped out by the Pacific Rats (Rattus exulans (Peale)) that had been introduced to the islands by the first Polynesian settlers. [1]
