General description of worker. Workers monomorphic. FIGURES 6–12. Asian species of the Crematogater brevis complex in lateral view. Scale bars are all 0.5mm. 6, Crematogaster bouvardi [Doi Suthep, Chiang Mai, North Thailand]; 7, C . brevis [Bogor, Java]; 8, C . kojimai [path 3, Cameron Highlands, Malay Peninsula]; 9, C . overbecki [Singapore]; 10, C . treubi [7 miles, Cameron Highlands, Malay Peninsula]; 11, C . walshi [Puri, Bengal]; 12, C . yappi [Gunung Inas, Kedah]. Compound eyes not projecting from lateral margin of head, the outer margin of eye almost flush with head capsule in full face view. Scape not reaching posterior corner of head, the scape with standing setae. Anterior margin of pronotal collar almost straight or slightly convex in dorsal view. Metanotal groove concave in lateral view. Propodeal spines developed, but their length variable. Anterior margin of metapleural gland bulla exceeding anterior margin of propodeal spiracle. Petiole in dorsal view broader anteriorly than posteriorly in smaller workers, broader at middle portion in larger workers. Postpetiole strongly bilobed behind without a distinct longitudinal median sulcus. Subpetiolar and subpostpetiolar processes undeveloped. Clypeus relatively smooth, 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. Mesopleuron weakly sculptured, but the higher portion with longitudinal rugulae in lateral view. Dorsal face of head, clypeus and mesosoma with abundant standing setae. Fourth abdominal tergite with sparse standing setae. Distribution. This species is known only from the type locality in India . Remarks. This species is distinct in having the strongly bilobed postpetiole.
