Distribution ( Fig. 35A View FIGURE 35 ). Prionopelta amabilis is known from the east coast of Honduras to south Brazil.

Comments. The limits between P. antillana and P. amabilis have been one of the main taxonomic problems of the genus in the Neotropics, given their morphological similarity and sympatric distribution. South American specimens of P. amabilis have been historically considered probable morphological variations of P. antillana . In Central America, material corresponding to our new species P. dubia sp. n. has been routinely misidentified as P. amabilis or P. antillana .

Here, the differences among the species are finally clarified, mainly in terms of density of pubescence and sculpturing, shape of clypeus, comparative length between the median and basal tooth of the mandible, and convergence of the subpetiolar process margins. In P. amabilis , the pubescence is sparse, the sculpture is shallow, the anterior clypeal margin is slightly projecting medially (somewhat triangular), the median tooth of the mandible is distinctly shorter than the basal tooth, and the margins of the subpetiolar process are parallel or subparallel. Prionopelta dubia sp. n has dense pubescence, the sculpture is shallow, the anterior clypeal margin is evenly rounded, the lengths of the median and basal teeth of mandible are similar, and the margins of the subpetiolar process are subparallel or parallel. Prionopelta antillana has the anterior clypeal margin slightly projecting medially, the median tooth of the mandible is distinctly shorter than the basal tooth, and the margins of the subpetiolar process are apically convergent.

Natural history. The species is mainly known from litter samples collected in tropical forests; reported at elevations of 50– 960m. They nest in rotting logs and colonies may have large numbers of workers.

Hölldobler & Wilson (1986) and Hölldobler et al. (1992) observed captive colonies collected during the dry season in well-developed secondary rainforest of Costa Rica.

In the 1986 study, the authors censused and excavated colonies, observed the behavior of the ants and conducted a “cafeteria” experiment to study dietary choice, which consisted in offering living arthropods from leaf litter and rotting wood from the sites nearby original Prionopelta nests to the captive ants. Two large colonies were carefully excavated. The total population of the first colony was: one queen swollen with eggs, 709 workers, between 100 and 200 eggs, 82 larvae and 126 pupae; with the emergence of alate queens from the cocoons two days after the capture of the colony. The second population counted: a dealate queen, 282 workers, 100 eggs, 76 larvae and 264 pupae. Authors considered that the colonies are both monogynous and polydomous, discrete and kept apart by nestmate recognition.

Cafeteria trials suggested a preference for campodeid diplurans as prey. The authors offered land snails, isopods, spiders, ricinuleans, mites, phalangids, pseudoscorpions, geophilomorph centipedes, millipedes, pauropods, campodeid and japygid diplurans, lepismatid and machilid thysanurans, entomobryomorph collembolans, kalotermitid and nasutermitine termite nymphs and workers, zorapteran nymphs and adults, hemipteran, tettigonid, earwig and gryllid nymphs as well as larvae and adults of ants and beetles. Prionopelta amabilis was capable of kill most of the groups cited above in two or three minutes, only ignoring the snails, spiders, phalangids, ricinuleans and millipedes.

They affirm that the species has a rudimentary but well-marked division of labor based on age, correlated in turn with early rise in ovarian development and a decline as the workers turn increasingly to foraging. Also, the authors divided the workers in three classes based in age and the increasing of body pigmentation: light callow, medium callow and fully pigmented. Additionally, they provided interesting notes regarding grooming, trophallaxis, trophic eggs, brood care, alarm and what is called the phenomena of “ wall-papering” and “ foot-dragging”.

The grooming among workers and self-grooming was less frequent than from workers to queen. No evidence of adult transport nor trophallaxis was found. Workers can have well-developed eggs and older workers frequently offered eggs to the queen, with no report of she feeding from any other manner. Workers were observed segregating eggs, small larvae, large larvae and pupae into separate piles; complementarily to this, the authors observed a “wallpapering” phenomenon, where they inferred that cocoon layers present in the walls of the galleries housing pupae served to keep them from growing to moist, contrary to the galleries occupied by the queen, eggs, larvae and resting group of workers. Workers rapidly responded to air currents and sudden illumination with a body vibration, also observed in the first approach to the queen and sometimes between workers, but the authors did not find any alarm pheromone. Nevertheless, when the workers were placed in a strange surface, they observed that the ant extended the legs backwards and dragged the tarsi for short intervals. This “foot-dragging” phenomenon was thought to be probably associated with trail laying or home range.

In the 1992 study, the “foot-dragging” phenomenon was further explored. One large colony was collected, containing two queens with active ovaries and filled spermatheca, more than 500 workers and many larvae and pupae. Complementing the behavior associated with the phenomenon described above, a rapid vertical shaking of the body performed by the workers was frequently observed.

Observations of the ants’ behavior as well as histology of front, middle and hindlegs were made, and the findings suggested that P. amabilis employ recruitment communication, somewhat associated with the “foot-dragging” phenomenon and the body shaking. The authors reported the presence of basitarsal glands in the hindlegs of workers and queens of the species, and demonstrate that their secretions are employed during recruitment to food sources and to new nesting sites; this is made during the perform of mechanical signals cited above, which apparently stimulates the nestmates to follow the trail.

Prionopelta amabilis workers have been seen “walking under the fungus garden of Apterostigma sp., in the ground under a large rotten log” (Lívia Pires do Prado pers. comm., #LPP_303).
