Worker description As in L. rufipes: Medium sized species head long and slender, excluding mandibles nearly twice as long as broad. Head widest just anterior to eye level. Sides of head subparallel, narrowing anteriorly, genae slightly concave. Head posterior to eyes narrowing abruptly to dorsoventrally flattened neck-like constriction, project- ing posteriorly. Masticatory margin of mandible with 15 to 20 teeth and denticles interspersed. Anterior cly- peal margin flat to weakly concave. Eyes positioned posterior to midline of head, relatively elongate, hairless, not surpassing margins of head. Antennae not compressed, scapes surpassing posterior margin of head by 2/3 their length. Pronotum slender, elongate. Propodeum short, dorsal face slightly impressed tranversely at anterior end, declivitous face short and convex, angle very rounded. Petiole triangular in profile, anterior and posterior faces with median longitudinal impression, dorsum lacking an impression, posterior face longer than anterior face. Ventral surface of petiole nearly flat. Gaster elongate-elliptical. Legs very long and slender, not com- pressed. Surface very finely shagreened and somewhat shining throughout. Mandibles with a coarse row of punc- tures along margin. Pubescence pale, sparse. Hairs minimal, confined to clypeus, venter and gaster. Body col- oration dark, generally mottled brown and rufotestaceous, with antennae uniformly dark brown and antennae uniformly rufotestaceous. Femora solid dark brown, with proximal portion pale and coxae mottled dark and light. Tibiae and tarsi pale yellow. Pronotum dark brown, mottled, with the remainder of thorax rufotestaceous with variable brown mottling. Gaster solid black with terminal gastral segments yellow.
