Nothing is known about the biology of Dilobocondyla rugosa.
Identification
Zettel and Bruckner (2013) - Worker: Black; scape, distal tarsomeres, and base of gaster yellow. Posterior margin of head concave. Frontal carinae strong, reaching posterior corners of head. Sculpture of head and especially of mesosoma coarse; interspaces on head mostly reticulated, on mesosoma smooth and strongly shiny. Petiole very slender, PtI 196 - 219.
This species shares a bicoloured gaster tergite 1 (with yellow base) with Dilobocondyla carinata, but strongly differs from that species by sculpture and the lack of a transverse ridge on the petiole. Dilobocondyla selebensis from Sulawesi, described from a gyne shares a concave hind margin of the head and strong rugae on its dorsal surface, but it has less developed antennal scrobes, is entirely black and relatively large (TL ca. 6 mm).

Colour: Body chiefly black. Mandibles yellowish brown. Antennae dark brown; scape and base of funiculus yellow. Legs brown; trochanters, bases of femora, and distal tarsomeres pale. Gaster tergite 1 with distinct yellow mark at base.
Structures: Head dorsally and on genae with almost regular striation and scarce interconnections, rather reticulated below and behind eyes. Interspaces on dorsum of head usually with distinct micro-reticulation that is only reduced and indistinct near hind margin and medially of frontal carinae. Posterior margin of head concave; hind corners angular. Frontal carinae and antennal scrobes reaching hind corners. Clypeus with three distinct longitudinal rugae (medial one short in small specimens), its surface smooth, at most with traces of a micro-reticulation.
Mesosoma almost entirely with very coarse reticulation; highly elevated rugae forming large polygonic meshes; an imaginary line between pronotal corners transecting nine or ten meshes; mesopleura partly smooth, as shiny as all interspaces. Petiole anterodorsally with fine micro-reticulum; posterodorsally and laterally with coarse irregular rugae, at most with remnants of microsculpture; in lateral view slender, dorsal outline almost evenly convex, anteroventral process spine-like, slender. Postpetiole in lateral aspect distinctly raised, with broadly rounded apex; anterodorsal surface with very fine rugae and distinct micro-reticulation, posterodorsal surface with regular longitudinal rugae and smooth interspaces. Gaster tergite 1 at base with very dense fine striation that gradually changes to a fine reticulum where the yellow mark ends.
