Hypoponera atavia

Introduction

Hypoponera atavia is an extinct ant species known only from fossilized Baltic amber dating to the Eocene epoch, approximately 44 million years ago. Workers measured about 3mm in total length, making them small, slender ponerine ants with a characteristic petiolar scale and a well-developed sting . The species was originally described as Ponera atavia by Mayr in 1868 and later transferred to the genus Hypoponera by Dlussky in 2002 based on morphological analysis of the type specimens . It is closely related to the extant species Ponera coarctata, sharing similar body proportions and habits . This species cannot be kept in captivity. As an extinct fossil species known only from amber inclusions, no living specimens exist. The few workers, queens, and males known from the fossil record were preserved in ancient tree resin, and their preserved anatomy tells us about their likely behavior, they lived in soil or leaf litter like modern ponerine ants, with workers rarely climbing into vegetation . For antkeepers interested in this species, the only option is to study the remarkable fossils preserved in Baltic amber collections.
