Longino (Ants of Costa Rica) - Apical fork of mandible with one intercalary tooth; mandible often with acute preapical tooth very close to apical fork, but may be reduced to small denticle or absent; no other preapical teeth; gaster smooth and shining, with long flagelliform setae; pronotal dorsum finely reticulate-punctate, usually without any costulate sculpture; but if a few faint costulae occur they are insignificant and obviously secondary to the reticulate-punctate component.

Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.
Bolton (2000) - TL 2.7-3.2, H L 0.68-0.75, HW 0.47-0.54, CI 69-75, ML 0.42-0.47, MI 60-65, SL 0.48-0.54, SI 96-102, PW 0.30-0.35, AL 0.68-0.76 (12 measured).
Preapical dentition of mandible very variable: may be entirely absent but usually there is a denticle or small tooth (size variable) on one or both mandibles close to the apicodorsal tooth. This denticle/tooth may be larger on one mandible than on the other, or present on one but not the other. More proximally mandible unarmed, or one or both with a minute denticle or tumulus. Considerable variation may occur within a single nest series. Both pairs of standing hairs on cephalic dorsum stiff, simple to spatulate. Apicoscrobal hair and pronotal humeral hair flagellate; a flagellate pair present on mesonotum and similar hairs numerous on waist segments and first gastral tergite. Pronotal dorsum reticulate-punctate, often only this sculpture present but sometimes a few very feeble superficial rugulae may occur; if so the rugulae are very faint, widely spaced and distinctly secondary to the reticulate-punctate sculpture. Mesopleuron, and usually also metapleuron, with a smooth unsculptured area; presence and extent of smooth area on metapleuron variable and in some specimens the entire sclerite is reticulate-punctate. Posterior (free) margin of propodeal lamella straight to weakly convex for most of its depth; propodeal lacuna conspicuous. Ventral surface of petiole with a curtain of spongiform tissue. Dorsum of petiole node reticulate-punctate. Disc of postpetiole variably sculptured, mostly smooth in some, in others smooth with peripheral weak sculpture or the whole surface feebly superficially sculptured; sometimes one or two weak rugulae present dorsolaterally.
