( Figs 14 View FIGURES 10 − 17 , 26 View FIGURES 21 – 26 )

Crematogaster deformis var. mucronata Emery, 1900: 690 . Holotype worker from INDONESIA: Pangherang-Pisang, Sumatra (E. Modigliani) (MCSN) [examined]. Combination in C. ( Physocrema ) and raised to species by Emery, 1922: 140; Donisthorpe, 1941: 226.

Crematogaster (Physocrema) fulmeki Forel, 1922: 95 View in CoL . LECTOTYPE worker (MHNG worker) (by present designation) and two paralectotype workers from INDONESIA: Sumatra (L. Fulmeki View in CoL ) (MCSN, MHNG) [examined]. See also Santschi, 1928: 127. Syn. nov.

Measurements and indices. HW 0.96–1.00; HL 0.92–0.97; CI 103–104; SL 0.68–0.69; SI 68–72; EL 0.16–0.19; PW 0.57–0.65; WL 1.03–1.09; PSL 0.10–0.12; PtL 0.28–0.32; PtW 0.22–0.24; PtH 0.16–0.19; PpL 0.19–0.20; PpW 0.26–0.28; PtHI 53–62; PtWI 70–76; PpWI 127–140; WI 117–119 (Three workers measured).

Description of worker. Workers monomorphic in size.

Scape not reaching posterior corner of head.

In lateral view, pronotum rises steeply; pronotum and mesonotum forming a single convexity; propodeum distinctly raised relative to promesonotum. Anterior margin of pronotal collar not concave in dorsal view. Metanotal groove convex posteriorly in dorsal view, deep; thorax strongly constricted in middle in dorsal view. In dorsal view, no longitudinal rugulae connecting between mesonotum and propodeum; the boundary distinct. Propodeal spiracle situated away from the metapleural gland orifice, the distance between them much greater than the propodeal spiracle diameter. Propodeal spines present.

In dorsal view, petiole subquadrate with subparallel sides, longer than broad. Postpetiole weakly bilobed but longitudinal median sulcus distinctly undeveloped, posterior corners acute.

Clypeus smooth and shining without distinct rugulae. Integument smooth.

Standing pilosity sparse, some pairs on dorsal face of head and many on dorsal portion of pronotum. Dorsal face of head with decumbent setae. Clypeus with long and short setae. Mesosoma with abundant setae. Fourth abdominal tergite with abundant appressed long setae.

Body color rufous to brown.

Distribution. This species is known from Sumatra ( Fig. 26 View FIGURES 21 – 26 ).

Remarks. This species is uniquely characterized by the combination of (1) 3-jointed antennal club; (2) steeply raised pronotum; (3) developed propodeal spines; (4) moderately swollen propodeum; and (5) processes of the posterior corners of the petiole in dorsal view. In the future, this species may be referred to another subgenus by these unique characters.

Specimens examined. INDONESIA: 2 workers, Satar’s House, Ulu Gadut, nr Padang, Sumatra, 15–16. viii. 1989 (E. Suzuki); 4 workers, Lubuk Gadang, Sumatra, 21–23. viii. 1985 (Sk. Yamane).
