Nothing is known about the biology of Crematogaster treubi.

Identification

A member of the Crematogaster irritabilis group. Hosoishi and Ogata (2012) - This species is similar to C. kojimai, but can be distinguished by the long and slender propodeal spines.

Slight morphological variations are found not only in the specimens collected from different localities, but also within nest series collections. Some specimens collected in Bali have shorter propodeal spines in contrast to the usual long and slender spines. The mesopleuron is relatively smooth and shining in most specimens, but especially shining in Sepilok specimens or somewhat shagreened in Pulau Sebeku specimens. These variants are treated as intraspecific variation within C. treubi until molecular data are available.

Anterior margin of pronotal collar almost straight or slightly concave in dorsal view. Metanotal groove shallow.

Anterior margin of metapleural gland bulla reaching or 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. Longitudinal rugulae developed anteriorly and posteriorly of the metanotal groove in lateral view.

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