Plagiolepis labilis

Pendahuluan

Plagiolepis labilis is an extinct ant species known only from fossil workers preserved in Sicilian Amber from the Miocene epoch, roughly 11 to 16 million years ago . Workers reached up to 2 mm in length and featured a slender build with very elongated antennae and legs . Their bodies carried fine punctuation, abundant long pubescence, and rigid bristles . The head sat low and showed a distinct notch at the back, while the mandibles pointed forward and the clypeus rose in the middle . You will only find this species in paleontological collections or academic literature, as living colonies do not exist . The fossil specimens show clear signs of preservation distortion, including stretched legs and overly slender contours that likely resulted from desiccation inside the amber . Despite these alterations, the narrow proclivis petiolar scale and convex thorax remain clear diagnostic traits . This species offers a rare glimpse into ancient Formicinae ecology, but it remains entirely unavailable for modern antkeeping .
