Known only from the type collection, nothing is known about the biology of Lordomyrma limatula.

Identification

Taylor (2012) - Readily distinguished from other species discussed here by the relatively reduced sculpturation, which differs clearly from that of the somewhat similar Lordomyrma diwata.

Description

Worker

General features as seen in images. Conformation similar to Lordomyrma azumai. Vertexal margin weakly convex in frontal view; humeral nodules lacking; the mesosomal dorsal profile in lateral view almost straight: promesonotum barely raised above propodeal dorsum, metanotal groove relatively weakly depressed; propodeal spines proportionally a little shorter than in L. azumai. In side view the promesonotum rises sharply from the relatively narrow nucal collar. Mandibles smooth and shining, with a few very small piligerous punctures. Clypeus smooth and shining. Frons with scattered incomplete, slightly sinuous fine longitudinal costulae, the intervening surfaces largely smooth and shining, minutely weakly rippled in reflected light. Sides of head more densely sculptured, moderately rugose. Antennal scrobes shining, with quite strongly effaced traces of fine puncturation. Promesonotum smooth, shining dorsally, with moderately fine traces of effaced punctate-rugosity laterally and posteriorly, extending to dorsum and sides of propodeum. Nucal collar shining, almost without sculpturation. Propodeal declivity smooth, shining. Petiole and postpetiole somewhat obscurely transversely sculptured. Gastral dorsum smooth, shining, with relatively small, somewhat obscure stellae at the hair-bases, minutely microreticulate posteriorly. Anterior coxae brightly reflective with no trace of sculpturation; very weak traces of transverse striae on second and third coxae; legs otherwise smooth, shining, with minute piligerous punctures. Pilosity as seen in images. Color uniformly rich Siena-brown, antennae and legs a shade lighter. Dimensions: (Holotype, smallest paratype, largest paratype): TL 3.4, 3.0, 3.4; HW 0.76, 0.73, 0.78; HL 0.81, 0.79, 0.82; CI 94, 92, 95; EL 0.17, 0.15, 0.17; OI 22, 20, 22; SL 0.59, 0.56, 0.58; SI 78, 76, 74; PW 0.58, 0.56, 0.58; WL 1.03, 1.00, 1.04; DPW 0.21, 0.21, 0.22; DPpW 0.29, 0.27, 0.29; GW 0.74, 0.73, 0.81.

Queen

General features as seen in images. Dimensions (smallest paratype, largest paratype): TL 3.9, 4.0; HW 0.84, 0. 86; HL 0.85, 0.86; CI 99, 100; EL 0.23, 0.23; OI 27, 27; SL 0.57, 0.58; SI 68, 67; PW 0.61, 0.63; SW 0.70, 0.69; WL 1.19, 1.22; DPW 0.24, 0.24; DPpW 0.30, 0.31; GW 0.93, 0.92.
