Cutter, leaf litter (ANIC, ANIC32- 011657 ). Diagnosis. Antero-medial surface of pronotum immediately behind the collar with at most very weak sculpturing and sometimes nearly smooth, this region differing significantly from the more heavily sculptured posterior regions of the pronotum and mesonotum; sculpturing on pronotum running longitudinally and generally with the central carina (or carinae) running nearly the length of the mesosoma; body smaller (HW < 0.60mm , MTL < 0.30mm ); head elongate (CI <95). This species is most similar to eruga and silvalaeva in the pattern of sculpturing on the pronotum but differs from eruga in being smaller and with a more elongate head and from silvalaeva in the longitudinal (rather than transverse) carinae on the dorsum of the mesosoma. Worker description. Antennal scapes smooth or with very low ridges. First segment of funiculus coneshaped. Sides of head behind compound eyes smooth. Sculpturing on dorsal surface of mesosoma shallow “V”s, the dorsal surface of pronotum immediately behind the collar and central mesonotum essentially smooth. Carinae extending continuously from the dorsal surface onto the lateral surfaces of the mesosoma. Metanotal spines weakly developed and essentially absent. Propodeal spines long. Erect hairs abundant, straight. Colour dark brown-black, antennae, mandibles, legs and tip of gaster yellow. Measurements. Worker ( n = 8) — CI 90–95; HL 0.53–0.60; HW 0.50–0.56; MTL 0.25–0.29; SI 81–92; SL 0.44–0.50; WL 0.62–0.72. Additional material examined ( ANIC ).
