Through the courtesy of Dott. Delfa Guiglia, I have been able to examine a syntype worker, which, with her permission, is herein designated as lectotype.

Lectotype worker. HW 2.59 mm, HL 4.20 mm, SL 4.20 mm, PW 1.55 mm, petiolar node length 1.13 mm, distance from the level of the basal line of the petiolar node to the tip of the petiolar spine 1.55 mm. Striae of the head limited to the transverse depression just anterior to the ocular ridge, and not extending onto the ridge itself; remainder of head smooth and shining. Anterior “neck” of pronotum transversely striate, remainder of pronotum smooth and shining. Entire mesonotal and propodeal surfaces transversely striate, the mesonotal striae much more feeble than those on the propodeum, becoming obsolescent anteriorly and medially. Anepisternum striate; katepisternum striate only along its dorsal margin, the remainder of its surface smooth and shining. Petiolar node and gaster entirely smooth and shining. Body uniformly dark reddish brown, appendages medium reddish brown.
