Pachycondyla mirabilis

Nothing is known about the biology of this species.

Identification
From Mackay and Mackay (2010): Pachycondyla mirabilis is an easily recognized species as it is the only one in the genus with the following combination of characteristics: well developed conical setae on the middle tibia, yellow in color and with a smooth and glossy integument. Pachycondyla mirabilis can be separated from other members in the ochracea species complex as the integument of Pachycondyla guianensis, Pachycondyla holmgreni and Pachycondyla gilva is dull or only weakly shining. Other shiny species of New World Pachycondyla (Pachycondyla carbonaria, Pachycondyla commutata, Pachycondyla laevigata, and Pachycondyla marginata) are all black.

Distribution

Habitat
Pachycondyla mirabilis occurs in mature montane rainforest, between 550 - 650 meters elevation. (Mackay and Mackay 2010)

Worker
The worker is a relatively small (total length 7 mm) yellow shiny ant. The masticatory border of the mandible has approximately 15 small teeth. The eye is completely absent or is indicated only by a small depressed area. The scapes are short and fail to reach the posterior border by approximately the first two funicular segments. The scape is noticeably widened toward the apex. The posterior border of the head is distinctly concave. The malar carinae and pronotal carinae are completely absent. The mesosoma is constricted in the region near the metanotal suture and slightly depressed in this region, but the metanotal suture is barely marked on the dorsum of the mesosoma. All of the femora are swollen, especially that of the middle leg. The petiole is broad when viewed in profile, with the anterior and posterior faces being nearly parallel, the posterior face is rounded into the dorsal face, which is approximately the same length as that of the anterior face. The subpetiolar process is angulate and well developed. The ventral surface of the petiole has a sharp process anteriorly, which broadens posteriorly. The petiole is elongated when viewed from below.

Erect hairs are present, but short on the mandibles, long on the clypeus and dorsal and ventral surfaces of the head, the hairs on the scapes are fine, abundant and erect or suberect, the dorsum of the mesosoma, petiole and all surfaces of the gaster have erect and suberect hairs. The tibia of the middle leg also has coarse setae on the outer surface.

All surfaces, including the mandibles, are smooth and glossy.

The ant is a concolorous golden yellow with the mandibular teeth and the area of the frons being slightly darker in color.
