Etymology L fimbriata , 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.
