Pristomyrmex rasnitsyni

Giriş

Pristomyrmex rasnitsyni is an extinct ant species known from a single fossil worker preserved in Late Eocene Danish amber, approximately 40 million years old . This is the only known fossil species within the genus Pristomyrmex, which makes it particularly significant in palaeomyrmecology (the study of ancient ants) . The worker measures approximately 3.0 mm in total body length, with an 11-segmented antenna featuring a distinct 3-segmented apical club, and possesses relatively long propodeal spines . The species was named in honor of Professor Alexandr Pavlovich Rasnitsyn, a renowned Russian hymenopterist and palaeontologist . It shares diagnostic features with the modern P. punctatus group, including the lack of spines on the pronotum and coarse reticulate sculpture on the head and alitrunk . IMPORTANT: This is a FOSSIL species that cannot be kept in captivity. No living specimens exist, and the species went extinct approximately 40 million years ago.
