Geographic range. Honduras (La Mosquitia) to Panama.

Diagnosis

Lowland; mandible smooth and shiny to faintly striate; anterior clypeal margin truncate; side of head bare or with a few inconspicuous erect setae; petiolar node moderately tapering, scale-like; color orange. The most similar species is R. minuta   ( Fig. 6 View Fig ; Supp Figs. S22 and S23 [online only]), which has longer scapes on average (mean SI 77 vs 73).

Measurements, worker: HW 0.84 (0.80–0.91, 26); HL 0.96 (0.93– 1.02, 26); SL 0.64 (0.60–0.66, 7); PTH 0.57 (0.55–0.62, 23); PTL 0.36 (0.34–0.40, 23); CI 88 (86–91, 26); SI 73 (72–74, 7); PTI 63 (60–68, 23).

Measurements, queen: HW 0.87 (0.84–0.91, 4); HL 0.98 (0.97– 0.99, 4); SL 0.65 (0.64–0.67, 2); PTH 0.59 (0.59–0.60, 3); PTL 0.37 (0.36–0.38, 3); CI 89 (86–92, 4); SI 74 (73–74, 2); PTI 62 (61–63, 3).

Biology

This species occurs in lowland wet to seasonal dry forest habitats, with records from 50 to 1100 m elevation. BOLD data associate a male from a Malaise trap in Santa Rosa National Park, a dry forest site in Costa Rica. Most specimens are workers and the occasional dealate queen in Winkler samples of forest floor litter and rotten wood. One worker was hand collected beneath a stone. An inexplicable record is a worker in a vegetation beating sample from an 1,100 m site on the Barva transect in Costa Rica. An alate queen was collected in February in a Malaise trap.

Comments

This is one of the two smallest species, the other being R. minuta   . These two species have mean HW <0.9, while all other species have mean HW> 0.9. Both are lowland species. They are allopatric, R. pluviselva   occurring east and south of the Sierra de Agalta in Honduras, and R. minuta   occurring north and west of this range. They are extremely similar, but differ in relative scape length: R. minuta   , SI 76–80 (n = 7); R. pluviselva   , SI 72–74 (n = 7).

BOLD COI data unite specimens from Honduras (Las Marias), Nicaragua (Saslaya), Costa Rica (Barva transect, Santa Rosa National Park, Osa), and Panama (Barro Colorado Island). UCE data likewise unite two specimens, one from Saslaya and one from the Barva transect, and the COI sequence from these specimens is consistent with the BOLD results. We have not examined Panama specimens directly, but BOLD images of a dealate queen from the Barro Colorado Island match our concept of R. pluviselva   . The COI data form four geographically structured BINs with Panama sister to Costa Rica northward, and Pacific slope Costa Rica sister to an Atlantic slope region that extends from Costa Rica to Honduras. Pacific slope Costa Rica further separates into two BINs, based on one specimen from Santa Rosa National Park and one specimen from the Osa Peninsula.
