Daceton boltoni

Daceton boltoni is a Neotropical species of arboreal ants in the subfamily Myrmicinae. The species occurs in Peru and Brazil and is similar to its sister species, "D. armigerum".
Distribution.
It seems to be exclusively canopy-dwelling and is known to occur in Iquitos, Peru, and Manaus and Cotriguaçu, Brazil. "D. boltoni" is sympatric with "D. armigerum". Although its known distribution is currently only two locations in the Amazonian forest, it is possible and indeed likely that "D. boltoni" shares a broadly overlapping distribution with "D. armigerum".
Description.
The worker caste of "D. boltoni" shares many important character states with that of its sister species "D. armigerum", including the heart-shaped head, the large eyes located on a low cuticular prominence, the number of apical mandibular teeth, and general habitus. "Daceton boltoni" differs from "D. armigerum" by the absence of a specialized row of thick setae on the inner (masticatory) margin of the mandibles; by mandibles that are slightly shorter and more stout, which could indicate differences in prey preferences between the two species; by a broad gap, when seen in profile, between the bases of the fully closed mandibles and the margins of the head capsule; by shallow depressions adjacent to and ventral to the mandibular insertions; by long and simple lateral pronotal spines; by a weakly impressed metanotal groove; and by subdecumbent to decumbent hairs on the tergite of abdominal segment IV.
Behaviorally, "D. boltoni" appears to be very similar to "D. armigerum". However, drop tests conducted at the type locality indicate that "D. boltoni" individuals exhibit weak and inconsistent aerial gliding behavior relative to those of "D. armigerum".
Gynes and males are unknown.
Worker variation.
Among the specimens studied in the original description, Azorsa & Sosa-Calvo (2008) documented some morphological variation, including:
