Lordomyrma idianale Taylor, 2012

Sympatric on Mt Isarog with Lordomyrma diwata and Lordomyrma emarginata.

Taylor (2012) - Readily distinguished by its intense sculpturation, L. idianale is smaller than the similarly sculptured Lordomyrma emarginata, and more closely conforms to the Lordomyrma azumai configuration.

Description

Worker

General features as seen in images. Conformation of head, mesosoma, waist nodes and gaster similar to Lordomyrma azumai. The head a little less expanded behind the eyes in frontal view; vertexal margin weakly convex; humeral nodules equivalent to those of L. azumai lacking; promesonotum barely raised above propodeal dorsum in profile; propodeal spines acute, relatively small, proportionately about half as long as in L. azumai. Antennal club obscurely 3-jointed. Metanotal groove with several raised transverse ribs. Pre-gastral body surfaces almost entirely reticulate-rugose, the interspaces smooth and shining, as seen in images. Incorporated traces of longitudinal striae between the antennal scrobes. Clypeus shining. Antennal foveae very finely densely punctate. Head ventrally smooth and shining. Propodeal declivity more-or-less smooth, shining, with traces of effaced transverse striae. Gaster smooth, shining, with minutely sculptured stellae at the hair bases; the surface overlain with a minutely incised microreticulum posteriorly. Exposed terminal gastral tergites similarly sculptured. Anterior coxae smooth, shining, with very faint traces of fine, transverse sculpturing. Remaining coxae and legs shining, with relatively weak traces of puncturation. Pilosity as seen in images. Color dark mahogany, the antennae and legs more lightly reddish-brown.
