Nothing is known about the biology of Crematogaster kojimai.


Hosoishi and Ogata (2012) – This species is similar to Crematogaster treubi, but can be distinguished by the short and stout propodeal spines. The nest series in Cameron Highlands (e. g. SH10-Mal-83) was collected from Dischidia astephana (c.f. Rintz, 1980).

HW 0.6-0.71; HL 0.61-0.69; CI 95-104; SL 0.45-0.51; SI 69-77; EL 0.1-0.13; PW 0.34-0.4; WL 0.66-0.77; PSL 0.05-0.09; PtL 0.16-0.2; PtW 0.18-0.22; PtH 0.11-0.14; PpL 0.1-0.14; PpW 0.14-0.19; PtHI 60-82; PtWI 100-129; PpWI 114-158; WI 78-94 (Twelve workers measured).

Workers monomorphic. Compound eyes slightly projecting from lateral margin of head. Scape usually just reaching posterior corner of head in smaller workers, not reaching it in larger workers, the scape with standing setae.

Anterior margin of pronotal collar almost straight in dorsal view. Metanotal groove concave in lateral view. Propodeal spines short and stout, their length shorter than the diameter of propodeal spiracles. Anterior margin of metapleural gland bulla exceeding anterior margin of propodeal spiracle.

Petiole in dorsal view broader anteriorly than posteriorly. Postpetiole weakly bilobed, without distinct longitudinal median sulcus. Subpetiolar and subpostpetiolar processes undeveloped.

Clypeus relatively smooth and shining, but with feeble rugulae. Dorsal face of mesosoma almost smooth and shining. Dorsolateral face of pronotum smooth in dorsal view. Lateral surface of pronotum smooth and shining. Lateral surface of mesonotum with rugulae. Mesopleuron relatively smooth and shining, but the anterodorsal and lower portions weakly sculptured.

Standing setae abundant. Dorsal face of head, clypeus and mesosoma with standing setae. Fourth abdominal tergite with sparse standing setae.
