Description

Worker

Okido, Ogata, and Hosoishi (2020) - TL 2.57-2.75, HL 0.62-0.66, HW 0.62-0.67, CI 99-104, SL 0.56-0.62, SI 88-93, PW 0.43-0.45, ML 0.62-0.66 (3 measured).

Head subrectangular, as long as broad in full-face view; median portion of occipital margin concave; occipital corners rounded, not projected posteriorly. Masticatory margin of mandible bent at midlength (third small tooth or sixth tooth); apical tooth strong, third tooth robust, followed by 5 small teeth and a basal blunt tooth; small teeth frequently unclear. Dorsal surface of clypeus usually not concave; median portion of anterior margin projected with a median process but frequently reduced; lateral portion simple, lacking sharp ridge in front of antennal insertions. Anterior dorsal surface of labrum with paired denticles close to or fused with each other at base. Frontal carinae virtually absent, indistinguishable from rugae on dorsum of head. Eyes large and convex, varying in size with maximum diameter 0.11-0.13 mm and 7-8 ommatidia; malar space twice as long as diameter of eye or shorter in profile; distance between occipital margin and posterior margin of eye three times as long as diameter of eye. Antennal scape long, extending beyond posterolateral corner of head; antennal flange developed.

Dorsal outline of mesosoma convex in profile. Pronotum without denticles; anterior portion not marginate; anterior ventrolateral portion with denticle, but variable. Furrow between pronotum and mesoepisternal projection more or less broad. Eumetanotal spine present; the length longer than broad at base. Propodeal spine elongate, extending over vertical posteriormost limit of propodeum in profile. Propodeal lobe low. Propodeal spiracle large, situated near posterior margin of propodeum, apart from margin by its diameter. Petiole long, longer than high in profile, longer than broad in dorsal view; very small dorsal crest located at midlength in profile; subpetiolar process absent, but median longitudinal ridge at ventral portion present. Postpetiole slightly broader than petiole in dorsal view; lateral margin straight; anterior portion slightly raised in profile; ventral outline not projected.

Anterior margin of gaster not concave in dorsal view; first gastral sternum simple without median longitudinal ridge.

Head with straight rugae distinctly; ventrolateral portion smooth and shining. Clypeus smooth and shining. Mesosoma with straight rugae distinctly. Forecoxa with transverse rugae, but variable, frequently smooth and shining. Petiole and postpetiole with a few distinct rugae. First gastral segment smooth and shining. Head with sparse and long pilosity on dorsum. Mesosoma with sparse and long pilosity on dorsum, hairs of pronotum slightly longer than apical third segment of antenna. Pilosity of petiole as long as that of mesosoma. Petiole without hairs on ventral surface. Postpetiole with or without 1-4 hairs on ventral surface. Head and mesosoma black or dark reddish brown, forecoxae, petiole, postpetiole and gaster reddish brown, mandibles, antennae and legs yellowish brown.
