Taxonomic Notes
Sharaf et al. (2021): Monomorium barbatulum looks similar to some members of the genus Trichomyrmex in terms of the following characters: polymorphic with 12-segmented antennae that lacking the well-defined terminal club; masticatory margin of mandibles armed with 3–4 teeth; propodeum unarmed. However, M. barbatulum lacks a critical diagnostic character for the genus Trichomyrmex which is the absence of the transverse striations on propodeal dorsum. With the availability of more material for a comprehensive taxonomic investigation, together with additional molecular evidence(s), we will be able to resolve properly the taxonomic status of the species.
