Etymology L fimbriata   HNS , fringed, probably alluding to the pilosity on the venter of the waist.

Diagnosis A very large, small-eyed species immediately recognizable in the major by the dense fringe of short, suberect to erect hairs on the petiolar peduncle and entire venters of the petiole and postpetiole; the concave profde of the posterior dorsum of the head in side view; the large, stout propodeal spines; and the spinose postpetiolar node.

Minor: very small eyes, angular humerus in dorsal-oblique view, and with a fringe of short hairs on venter of petiole. Measurements (mm) Major (Benjamin Constant, Brazil): HW 2.60, HL 2.88, SL 1.20, EL 0.20, PW 1.06. Minor (Benjamin Constant): HW 0.84, HL 0.90, SL 0.84, EL 0.06, PW 0.52. Color Major: medium to dark reddish brown. Minor: concolorous brownish yellow.

Range One of the most widespread of all Neotropical ant species, recorded from Veracruz, Mexico, through Central and South America (including Trinidad) to Misiones, northern Argentina.

biology An inhabitant of tropical forests. At La Selva, Costa Rica, Longino (1997) found large numbers of minors and majors foraging at night over the ground from a soil nest. An incipient colony was discovered in a dead stick on the forest floor.
