Nothing is known about the biology of Allomerus brevipilosus.
Fernández (2007) - This species can be easily distinguished from other members of the genus with the following three characters: the short pilosity on the head, promesonotum and petiole and gaster, hairs of half or less than half the length seen in other species; short pilosity on the anterior clypeal margin without a differentiated central hair; and weak longitudinal clypeal rugulae, especially on the anterior half. The anteroventral petiolar spine is small but well defined.

- brevipilosus. Allomerus brevipilosus Fernández, 2007a: 164 (w.) BRAZIL.
Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.
Holotype: HW 0.52 HL 0.55 SL 0.36 WL 0.60 GL 0.54 TL 2.15 CI 94 SI 69.
Head nearly as wide as long. Antennae 10 segmented. In side view, promesonotum convex. Propodeal dorsal face very short, declivity slightly convex. Propodeal spiracle small. Petiole with peduncle shorter than node. Petilolar node with small, but well defined anteroventral spine. Body smooth and shining, especially head. Clypeal disc with several feebly irregular longitudinal carinulae. Lateral sides of propodeum finely rugose reticulate. Head with abundant short, decumbent hairs (less than 0.08 mm in length), moderate in number on promesonotum, few on propodeum, petiole and postpetiole. Few longer hairs on dorsum of head and promesonotum, none on propodeum, several on petiole, postpetiole and gaster. Row of very short, anterior clypeal hairs, medial inconspicuous. Body brown, most of head and gaster dark brown, hairs whitish.
Holotype worker: BRAZIL, Amazonas, Naue River (Museu de Zoologia da Universidade de Sao Paulo), collected in Gleasonia nauensis. Paratypes: 3 workers (not available for measurements), same data (MZSP).
The label data are imprecise “Nauí river (?), Amazonas, Ducke on - Gleasonia nauensis (?)”, but according to A. decemarticulatus distributional data in Kempf (1975), it has to be treated as Naué River in Brazil’s Amazonas state.
