3940878F2835FFF8CD824D41657EFF21.taxon	discussion	Polymorphism unknown (C. treubi group is monomorphic). The occipital carina developed as distinct ridge (Fig. 2 a). Pronotal shoulders developed as ridges (Fig. 4). The petiole in dorsal view rectangular, with angular anterolateral corners (Fig. 3 a). Postpetiole bilobed behind. Mesosoma with standing hairs sparse. This species group seems to be most similar to the Malagasy Mesocrema species, C. rasoherinae.	en	Hosoishi, Shingo, Ogata, Kazuo (2012): Revision of the Crematogaster brevis complex in Asia (Hymenoptera: Formicidae).

3940878F2836FFF8CD824B0B646CFD98.taxon	discussion	Workers monomorphic. The occipital carina undeveloped, not forming a distinct ridge (Fig. 2 b). Pronotal shoulders not developed as distinct ridges. The petiole in dorsal view broader anteriorly than posteriorly, with rounded, not angular, anterolateral margins (Fig. 3 b). The postpetiole weakly bilobed, but without distinct longitudinal median sulcus. Mesosoma with abundant standing hairs. This species group is easily defined by the undeveloped occipital carina and generally 2 - segmented antennal club, not only from C. brevis group, but also from other Asian Crematogaster species.	en	Hosoishi, Shingo, Ogata, Kazuo (2012): Revision of the Crematogaster brevis complex in Asia (Hymenoptera: Formicidae).

3940878F2833FFF2CD824BD364EAFBD9.taxon	discussion	Remarks. 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. Specimens examined.

3940878F283CFFF2CD824EA3615FF991.taxon	discussion	Remarks. We have not been able to examine type-material of C. treubi apilis. From the original description, this subspecies belongs to the C. treubi group. Forel (1913) described the following features: (1) scape exceeding posterior corner of head by two times of the width of the scape; (2) the metanotal groove deep. The first feature is not found in the other species of the C. treubi group. It is impossible to judge the depth of the metanotal groove from the original description. The taxonomic status of this subspecies will remain uncertain until the type-material can be examined.	en	Hosoishi, Shingo, Ogata, Kazuo (2012): Revision of the Crematogaster brevis complex in Asia (Hymenoptera: Formicidae).

This species can be easily distinguished from other species of the C. brevis complex found in Asia by its undeveloped propodeal spines.	en	Hosoishi, Shingo, Ogata, Kazuo (2012): Revision of the Crematogaster brevis complex in Asia (Hymenoptera: Formicidae).

3940878F283EFFF1CD824CF2655DFEB1.taxon	discussion	Remarks. Examination of syntype workers in MHNG and NHMB reveals that C. jacobsoni is not similar to the C. brevis group or C. treubi group in Asia. Characteristic features include: occipital carinae developed; petiole weakly broader anteriorly, but without angular corners; postpetiole weakly bilobed with longitudinal median sulcus. This species is similar to C. (C.) semperi Emery, 1893 or C. (C.) simoni Emery, 1893. We hereby transfer C. jacobsoni to the subgenus Crematogaster, to compare it with closely related species in this group in the future.	en	Hosoishi, Shingo, Ogata, Kazuo (2012): Revision of the Crematogaster brevis complex in Asia (Hymenoptera: Formicidae).
