General description of worker: Workers monomorphic.
Head round 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 distinctly projecting beyond lateral margins of head in full-face view. Scapes exceeding posterolateral corners of head.
Pronotal collar with weakly concave anterior margin in dorsal view, slightly 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 forming evenly arched, continuous dorsal outline. Metanotal groove in dorsal view transverse, almost straight in median portion, forming shallow concavity that is laterally margined by ridges. Propodeal spiracles oval, situat- ed at posteolateral corners of propodeum, apart from mepleural gland bullae. Propodeal spines developed, longer than diameter of propodeal spiracles, in dorsal view strongly divergent, in lateral view curved upward.
Petiole in dorsal view with subparallel sides and narrow short peduncle anteriorly, distinctly 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 undeveloped. Postpetiole in lateral view with strongly convex dorsum, distinctly higher than petiole, in dorsal view as wide as petiole, globular, not bilobed. 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 distinct pair of longitudinal shorter rugulae. Dorsal and lateral surfaces of pronotum smooth and shining; anterolateral shoulders of pronotum with rugulae. Mesopleura weakly sculptured, but sometimes smooth except for their marginal areas in some specimens (on anterior and central areas). Dorsal surface of propodeum weakly sculptured and with rugulae on anterodorsal areas. Dorsal surface of petiole smooth and shining. Lateral surface of petiole sculptured. Dorsal and lateral surfaces of postpetiole smooth and shining.
Standing pilosity sparse. Dorsal face of head with three pairs of long erect setae and short appressed setae sparsely. Clypeus with two pairs of long setae in anterior portion, one directed upward and the other downward. Anterior clypeal margin with one single long setae medially and one pair of long setae laterally. Scapes with appressed setae. Mesosoma with two pairs of long erect and stout setae (ps1PN, and psaMN) that are much longer than other erect setae and shorter pspMN. Posterolateral tubercles of petiole posteriorly with one pair of stout long setae. Postpetiole with one pair of stout long setae on disc posteriorly. Fourth abdominal tergite with erect setae sparsely (c. 8), but no decumbent to appressed setae.
Body red-brown. Apical two flagellar segments yellow, contracting with other flagellar segments that are brown.
Comments: In the worker this species can be distinguished from all other members of the C. baduvi group by the smooth and shining surface of mesosoma, propodeal dorsum with rugulae, and propodeal spines directed upward at the tip. This species is similar to C. baduvi and C. brunensis , but can be distinguished from them by upward-curved propodeal spines.
Distribution: This species is known only from the type locality in Indonesia (Sulawesi) ( Fig. 49 View Figure 49 ).
Etymology: The species name is dedicated to Dr. N. Stork (BMNH), who collected the type material.
Material examined: INDONESIA: three workers, Dumoga-Bone N. P., Utara, Sulawesi, 14.ii.1985 (No collector’s name) .
