Gesomyrmex flavescens

No formal diagnosis or comparative comments were provided when this species was described, only a key for determination. According to Dlussky et al. (2009), the diagnostic character for this taxon is said to be a straight anterior clypeal margin, but this trait is ambiguous in the fossil specimen. Aria et al. (2023) consider this species as species inquirenda.

Gesomyrmex breviceps, Gesomyrmex flavescens and Gesomyrmex pulcher have relatively disparate morphometrics and are not easily distinguished, complicated by the lack of original diagnoses (Aria et al., 2023).
