Taxonomic Treatment (provided by Plazi)

Fernández, F., 2003:
Adelomyrmex laevigatus MacKay , 2003:600 (w) in: Fernández & MacKay, 2003.
Worker diagnosis: Posterior border of head nearly straight. Mandibles with 5 teeth, the three apical-most larger. Anterior margin of clypeal plate concave (Fig. 54). Eye with about 5 to 12 ommatidia. Hypostomal tooth large, stout (Fig. 53). Promesonotum evenly convex and higher than propodeum (Fig. 51). Metanotal groove well marked. Propodeal dorsum short. Propodeal teeth longer than wide. In dorsal view, anterior margin of first tergum clearly concave. Head with rugae and foveae confluent. Dorsum of promesonotum largely smooth and shining, with trace of longitudinal rugulae on the sides (Fig. 56). Most of side of pronotum smooth and shining. Propodeum with transverse rugae. Dorsum of petiole and postpetiole smooth and shining, laterally with some oblique rugae. Pilosity on dorsum of body moderately long, scattered. Body dark brown, antennomeres lighter.
Queen and male: Unknown.
Comments. Adelomyrmex laevigatus can be separated from the other species in the genus as the promesonotum is nearly completely smooth and shiny, with only a few rugulae on the sides. No other species of Adelomyrmex possesses this characteristic, except A. micans , in which the entire head is also smooth and glossy. Additionally, the sculpture of the head is distinctive, with a mixture of rugae and foveae. The first tergite is notably concave when viewed from above. The hypostomal teeth are large, robust, much more than any other species in the genus (Fig. 53). The numbers of ommatidia ranges from 5-6 up to 12.
The species is known from Costa Rica and Panamá . Fernández & MacKay (2003:600- 601) offered distribution records.
