Rasopone JTL048

( Fig. 6 , Supp Fig. S45 [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. JTL048:

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 JTL047( Fig. 10 , Supp Fig. S44 [online only]): larger (HW 1.21 vs 0.98).

Measurements, worker: HW 0.98, HL 1.10, SL 0.79, PTL 0.39, PTH 0.72, CI 89, SI 81, PTI 54 (n = 1).

Biology

This species is known from one specimen from a lowland rainforest site, 380 m elevation, from a pitfall trap.
