Nothing is known about the biology of Crematogaster mucronata.

Identification

Hosoishi and Ogata (2009) - 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.

Description

Worker

Hosoishi and Ogata (2009) - 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).

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.

Type Material

Hosoishi and Ogata (2009) - Holotype worker from INDONESIA: Pangherang-Pisang, Sumatra (E. Modigliani) (Museo Civico di Storia Naturale, Genoa) [examined].
