Oliveira & Feitosa, 2019
Specimens of this species come from Reserva Natural Datanlí El Diablo, which is a patchy matrix of private coffee farms and primary and secondary cloud forests. The holotype was obtained from a sifted leaf-litter sample collected in a primary cloud forest, with many large oak trees and abundant tree ferns. The paratype was also found in a leaf litter sample from a montane wet forest, near coffee and agricultural clearings. Both localities are above 1300 meters of altitude.

Oliveira & Feitosa (2019) - Petiole unarmed; postero-ventral lobe short and evenly rounded; subpetiolar process weakly developed. Prora present; dorsal protuberance on posterior region of first gastral tergite absent.
Probolomyrmex cegua is similar to Probolomyrmex lamellatus, but has propodeal angles, absent in P. lamellatus, and the postero-ventral lobe of the petiole is rounded.

Worker description: Frontoclypeal shelflike projection micropunctate. Mandibles foveated, interval between the foveae covered by micropunctures; external surface of mandibular basal margin smooth. Tip of apical segment of antennae bearing different sized pits. Mesopleuron, metapleuron and lateral faces of propodeum alveolate and foveated; alveoli denser just above metapleural gland orifice; opening of metapleural gland narrow, with a smooth anterior region, surrounded rows of hairs.

The name refers to a folkloric figure from Nicaragua, known as La Cegua. She is a woman that walks through the woods and back roads, attracting drunk and unfaithful men and asking them for a ride. She poses as a beautiful lady so, men give her a ride, but when they turn around, instead of beholding the enchanting companion, they see a monster with the skull of a horse and fiery red eyes. The words she speaks to these men are so horrific that the victim goes insane instantaneously and never recovers (Janzen, 2012). The name is applied here as a noun in apposition.
