Queens measure 2.80-3.08mm in total length, with a robust mesosoma, distinctive granulopunctate sculpture on the head and mesosoma, and a ferrugineous-brown to dark brown coloration . The species belongs to the Micrommatum Clade and shows morphological similarities to Proceratium taino and Proceratium mexicanum, differing in specific measurements and indices . This fossil provides insight into ant diversity in the ancient Caribbean. However, the species is extinct and cannot be kept in captivity .
