Longino, John T. & Branstetter, Michael G., 2020, Phylogenomic Species Delimitation, Taxonomy, and ‘ Bird Guide’ Identification for the Neotropical Ant Genus Rasopone (Hymenoptera: Formicidae), Insect Systematics and Diversity 4 (2), No. 1, pp. 1-33 : 27

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.
