Description
Worker
General features as seen in images. Conformation similar to Lordomyrma azumai; vertexal margin broadly rounded in frontal view. Mesosoma proportionately short, its promesonotal profile more elevated and more evenly arched than in azumai. Promesonotal shoulders in dorsal view more evenly rounded, lacking nodules equivalent to those of L. azumai. Antennal scapes as in L. azumai. A generally shining species with sculpturation relatively reduced and reflective. Mandibles and clypeus smooth and shining, the former with a few scattered piligerous point-punctures. Frons anteromedially and behind smooth and strongly shining, with a band of vestigial longitudinal striate-rugosity on each side to beyond the level of the eyes. Sides of head coarsely punctate-rugose. Head ventrally smooth and shining. Antennal foveae generally smooth, strongly reflective, with very faint vestiges of fine shagreening near the antennal insertions. Occipital collar smooth behind, anterior section weakly shagreened. Promesonotal dorsum smooth, highly reflective with a few scattered piligerous punctae, more dense laterally. Propodeal dorsum moderately rugose, the declivity smooth and shining, without transverse striae between the spines. Sides of mesosoma behind pronotum moderately coarsely rugose but shining. Petiole anterodorsally smooth and shining, elsewhere punctate-rugose. Postpetiole similarly punctate-rugose. Gaster dorsally smooth and shining with scattered small piligerous point-punctures and a band of minute microreticulation behind; ventrally shining, with somewhat effaced dense moderate puncturation. Antennal funiculi densely, minutely punctate. Anterior coxae smooth, strongly reflective; middle and hind coxae with trace transverse striae; legs otherwise smooth with a few scattered punctae and traces of shagreening at the femoral bases. Pilosity as seen in images. Color generally dark mahogany-brown, the antennae and legs lighter brown.
