Rasopone JTL027

(Fig. 8; Supp Fig. S34 [online only])

Geographic range. Panama (Darien).

Diagnosis

Mandible striate; anterior clypeal margin truncate; side of head bare; petiolar node cuboidal. The other two species from Darien are much larger, with HW ≥ 1.4. It is similar to R. cryptergates (Fig. 7; Supp Figs. S8 and S 9 [online only]), but with relatively longer petiole (mean PTI 64 vs 57).

Measurements, worker: HW 1.12, HL 1.34, SL 1.07, PTL 0.51, PTH 0.80, CI 83, SI 96, PTI 64 (n = 1).

Biology

The species is known from a single worker, from a moist forest site at 810 m elevation. The worker was collected in a ravine, in excavated soil of a clay bank.

Comments

UCE phylogenetic results place this specimen together with three other species: two morphospecies from the same site in Darien (JTL029 and JTL030) and R. cryptergates from Costa Rica.
