Identification
Mackay and Mackay (2008) - The glossy surfaces of this species would easily separate it from nearly all of the other members of the genus. It could only be confused with Simopelta manni, which is also mostly smooth and glossy. It can be distinguished, as usually the entire dorsum of the head of S. manni (at least the posterior 1/4 ) is covered with coarse punctures, as is the dorsum of the pronotum. It is also slightly larger (the total length of S. manni is less than 4 mm), and has a wider head.

Description
Worker
The worker is a medium sized (total length 4 mm), shiny black ant. The mandible has 3 teeth, the two teeth near the apex are sharp and well-developed, the third (basal most) is thickened, with a somewhat rounded apex. The anterior border of the clypeus is broadly rounded. The eye is moderately large (maximum diameter 0.07 mm), and extends past the sides of the head. The antennal scape (0.78-0.80 mm) extends about the first funicular segment (0.18 mm) past the posterior lateral corner of the head. The head is relatively wide (head length 0.83-0.87 mm, and head width is 0.65 - 0.70 mm). The head is widest near the eye, and posterior border is nearly straight. The mesosoma is broadly depressed dorsally, and reaches the lowest point at the metanotal suture. The petiole is wide when viewed in profile, with well-developed spiracular horns, and a poorly developed subpetiolar process.
Erect hairs are sparse, but are present on the mandibles, the clypeus, dorsum of the mesosoma, petiole, and all surfaces of the gaster. Suberect hairs are abundant, and present on the scapes, dorsal and ventral surfaces of the head, mesosoma, legs, and are sparse on the petiole and gaster.
Most surfaces are smooth and glossy, including the entire dorsal surface of the head (with a few scattered punctures), the dorsum of the mesosoma, the side of the pronotum, the dorsum of the petiole, and gaster (with tiny, indistinct punctures); the mesopleuron and side of the propodeum have oblique striae. The side and both faces of the petiole have poorly defined striolae, and are mostly glossy.
Type Material
Holotype worker (Humboldt Institute), Colombia Huila PNN Cueva de Los Guácheros Cabaña Cedros 1°37’N 76°6’W, 1950m Winkler 2-5-xii.2002, R. Paramero Leg. M.3375.
Etymology
From Latin, laevigatus, meaning smooth, referring to the smooth sculpture of the worker of this species.
