Inhabits developed forests, and nests in soil or in leaf litter.


Hosoishi and Ogata (2016) - A member of the Crematogaster quadriruga group. In the worker this species can be distinguished from all other members of the Crematogaster quadriruga group by the distinct compound eyes, V-shaped metanotal groove in lateral view, large propodeal spiracles touching metapleural gland bulla, and short propodeal spines. This species is similar to Crematogaster philippinensis and Crematogaster sundalandensis, but can be distinguished from them by the short and stout propodeal spines (PSL 0.05–0.08 vs. 0.08–0.11 and 0.08–0.11 in the latters).

Workers monomorphic. Head subquadratic in full-face view. Mandibles with four teeth arranged at an equal distance, apical and subapical teeth large, basal two teeth smaller. Anterior clypeal margin convex in medial portion. Compound eyes slightly projecting beyond lateral margins of head in full-face view. Scapes reaching posterolateral corners of head.

Pronotal collar with weakly concave anterior margin in dorsal view, distinctly lower than pronotum in lateral view. Pronotal dorsum without distinct ridges laterally. Mesonotal dorsum with lateral ridges that irregularly extend posteriad to tips of propodeal spines. Pronotum and mesonotum in lateral view not clearly forming continuous dorsal outline; mesonotal dorsum flat. Metanotal groove in dorsal view transverse, almost straight in median portion, forming deep concavity that is laterally margined by lamellate ridges. Propodeal spiracles elliptical, situated at posterolateral corners of propodeum, touching to metapleural gland bullae. Propodeal spines developed, as long as diameter of propodeal spiracles, in dorsal view directed posteriad.

Petiole in dorsal view with subparallel sides, longer than wide. Posterior portion of petiole with short process that is slightly higher than posterior margin of petiole disc in lateral view. Subpetiolar process weakly developed as angulate tubercle. Postpetiole in lateral view with weakly convex dorsum, as high as petiole, in dorsal view as wide as petiole, weakly bilobed posteriorly but without longitudinal sulcus. Subpostpetiolar process undeveloped, but venter of postpetiole convex.

Integument essentially smooth and shining. Dorsal surface of head smooth and shining. Mandibles with feeble rugulae and smooth interspaces. Clypeus generally smooth and shining, but with one pair of longitudinal rugulae; rugulae not extending to posterior clypeal margin. Dorsal and lateral surfaces of pronotum smooth and shining; anterolateral shoulders of pronotum with rugulae. Mesopleura smooth and shining. Dorsal surface of propodeum smooth and shining, but one pair of rugulae running from metanotal groove to tips of propodeal spines. Dorsal surface pf petiole smooth. Lateral surface of petiole generally smooth, but with one longitudinal rugula. Dorsal and lateral surfaces of postpetiole smooth and shining.

Standing pilosity sparse. Dorsal face of head with suberect setae sparsely. Clypeus with two pairs of long setae in anterior portion, one directed upward and the other downward. Anterior clypeal margin with one pair of long setae medially and short setae laterally. Scapes with suberect setae. Mesosoma with five pairs of long erect and stout setae (ps1PN, ps2PN, psaMN, pspMN, and ps1PS) that are much longer than other erect setae. Posterolateral tubercles of petiole posteriorly with two pairs of long setae. Postpetiole with three pairs of long setae on disc anteriorly, posteriorly and laterally. Fourth abdominal tergite with erect to suberect setae abundantly, and short decumbent setae sparsely.

Body yellow. All flagellar segments yellow.

Type Material
