Rasopone JTL042

(Fig. 7; Supp Fig. S42 [online only])

Geographic range. Colombia, Brazil (Pará).

Diagnosis

Mandible striate; otherwise very similar to R. lunaris (Fig. 8; Supp Figs. S16–S18 [online only]).

Measurements, worker: HW 1.10 (0.94–1.23, 3); HL 1.22 (1.06– 1.35, 3); SL 0.87 (0.71–1.01, 3); PTH 0.80 (0.69–0.89, 3); PTL 0.43 (0.38–0.48, 3); CI 90 (89–91, 3); SI 79 (75–82, 3); PTI 54 (54–55, 3).

Biology

Two specimens are from the Santa Marta region of Colombia, one from seasonal forest at 260 m and one from montane forest at 1,300 m elevation. Both are from forest floor litter samples.

Comments

This species is a version of R. lunaris with striate mandibles. An old collection at MCZC is a pin with two workers labeled ‘ Para, Brazil, Beebe’. These specimens are a close match to the Colombian specimens, but given the geographic distance the similarity may be superficial and not reflect conspecificity.
