Fernández (2007) - Distinguished from the majority of the species in the genus because of its propodeal teeth and the larger propodeal spiracle that is located close to the propodeal tooth base and its opening is directed towards the sides and behind. Besides, the central apical clypeal seta is larger than its neighbors and the antennal scape thickens gradually apically. Allomerus vogeli and Allomerus maietae are two other species with propodeal teeth or spines. Allomerus dentatus and A. vogeli are similar in their general aspect and with lateral reticulation on the mesosoma. In A. vogeli the spiracle opening is lateral (posterior in A. dentatus) and so is seen as larger in lateral view; there are also several long hairs on the thorax and head. In A. maietae the propodeal spiracle position (high in this species) and hair length (nearly 0.2 mm) are characters that separate it easily from A. dentatus.

Holotype: HW 0.41 HL 0.50 SL 0.33 WL 0.45 GL 0.60 TL 2.00 CI 83 SI 79.
Antennae apparently 10 segmented. In side view, promesonotum slightly convex. Propodeal dorsal face short, declivity and basal faces separated by pair of teeth. Propodeal spiracle aperture opens posterolaterally, with large aperture and close to base of propodeal tooth. Petiole with peduncle shorter than node. Body smooth and shining, especially head. Sides of propodeum finely reticulate-rugose. Dorsum of mesosoma with long hairs (about 0.12 mm in length), present on postpetiole and gaster; very few on petiole and none on head and mesosoma. Row of short clypeal hairs on anterior margin, medial hair conspicuous. Concolorous brown, hairs whitish.
