Pachycondyla tristis

物种引言

Pachycondyla tristis is an extinct ant species known only from a single fossil queen preserved in Bitterfeld amber from the Late Eocene of Germany, approximately 34 million years ago . Dlussky formally described this species in 2009 based on the fossil, which measures about 4.5 mm in body length . As a fossil species, no living colonies exist, making it impossible to keep in captivity .
