Rasopone JTL047

( Fig. 10 ; Supp Fig. S44 [online only])

Geographic range. French Guiana.

Diagnosis

Mandible smooth and shining; anterior clypeal margin truncate; side of head with short erect setae; petiolar node subcuboidal; face sculpture of dense, minute puncta overlain with larger, more widely spaced puncta visible in particular orientation and lighting. Two species are within geographic and size range of R. JTL047:

Rasopone lunaris ( Fig. 8 ; Supp Figs. S16–S18 [online only]): posterior face of petiolar node more rounded; face with uniform small puncta, not overlain with larger puncta.

Rasopone JTL048 ( Fig. 6 , Supp Fig. S45 [online only]): smaller (HW 0.98 vs 1.21).

Measurements, worker: HW 1.21 (1.21-1.21, 2); HL 1.26 (1.26– 1.27, 2); SL 0.89 (0.88–0.89, 2); PTH 0.84 (0.81–0.87, 2); PTL 0.50 (0.48–0.51, 2); CI 96 (95–96, 2); SI 74 (73–74, 2); PTI 59 (55–63, 2).

Biology

This species is known from lowland rainforest sites, <800 m elevation, from Winkler samples of sifted litter and rotten wood.
