Odontomachus angulops

Introduction

Odontomachus angulops is an extinct trap-jaw ant known only from a single fossil queen preserved in Mexican amber from the Simojovel region of Chiapas, Mexico. This species lived approximately 16 to 23 million years ago during the Oligocene-Miocene period and represents the first fossil species described from the Odontomachus cornutus species group, as well as the first Odontomachus queen ever found in amber . The queen measured 10.72 mm in total length, making it significantly smaller than the extant O. cornutus queen and workers . Identification features include ocular prominences forming an obtuse angle and carinae on the ocular bridges . As a fossil species, no living specimens exist, and it cannot be kept in captivity.
