Nothing is known about the biology of Dilobocondyla carinata.
Identification
Zettel and Bruckner (2013) - Worker: Brown; with yellow mark on gaster tergite 1. Posterior margin of head concave. Frontal carinae strong, reaching posterior corners of head. Sculpture of head and mesosoma coarse; interspaces mostly shiny. Petiole with transverse carina. Postpetiole dorsally regularly striated.
Dilobocondyla carinata can be immediately distinguished from all congeners by the petiole bearing a dorsal transverse ridge. The presence of this ridge results in a low PtI of 167, although the petiole is slender as in other species of the D. chapmani group.

Description
Worker
Holotype: TL 4.35; HW 1.09; HL 1.14; CI 96; SL 0.70; SI 64; PnW 0.72; PtL 0.51; PtH 0.31; PtW 0.24; PtI 167; PpL 0.37; PpH 0.38; PpW 0.37. Paratype: TL 4.20; HW 1.06; HL 1.11; CI 95; SL 0.68; SI 64; PnW 0.71; PtL 0.50; PtH 0.30; PtW 0.24; PtI 167; PpL 0.36; PpH 0.37; PpW 0.37.
Colour: Head with mandibles, mesosoma and legs, petiole and postpetiole brown; dorsum of head, sides of mesosoma, and node of petiole slightly infuscated; trochanters and distal tarsomeres pale. Gaster blackish brown, tergite 1 with yellow mark anteriorly. Antenna dark brown except yellow scape.
Structures: Head with almost regular coarse striation, except more or less vermiculated rugae behind eyes. Interspaces shiny, almost smooth, at most with very superficial microsculpture. Posterior margin of head concave; hind corners angular. Frontal carinae and antennal scrobes reaching hind corners. Clypeus with five longitudinal rugae; interspaces weakly micro-reticulated.
Mesosoma almost entirely reticulated; coarse rugae forming large meshes; an imaginary line between pronotal corners transecting nine meshes; meso- and metapleura smooth, as shiny as all interspaces. Petiole dorsally unsculptured, laterally with longitudinal rugae; its outline in lateral view unique, anteriorly and posteriorly slender, at mid-length raised to a dorsal transverse ridge; anterodorsal and posterodorsal outline slightly concave; anteroventral tooth small, triangular. Postpetiole in lateral aspect subtriangular, with narrowly rounded apex; both anterodorsal and posterodorsal surface with regular coarse striation. Gaster tergite 1 at base with very dense fine striation that gradually changes to a fine reticulum where the yellow mark ends.

Etymology
The Latin adjective carinatus (= keeled) refers to the characteristic carina on the petiole.
