Nothing is known about the biology of Crematogaster yamanei.
Identification
Hosoishi and Ogata (2009) - This species is very similar to Crematogaster vacca. It differs in the reticulate rugulae on the head and promesonotum, and the relative depth of the metanotal groove.

Description
Worker
HW 1.15–1.7; HL 1.03–1.45; CI 112–118; SL 0.93–1.1; SI 65–81; EL 0.2–0.28; PW 0.63–0.9; WL 1.26–1.78; PSL 0.15–0.18; PtL 0.41–0.55; PtW 0.36–0.5; PtH 0.23–0.28; PpL 0.22–0.33; PpW 0.31–0.48; PtHI 50–57; PtWI 90–96; PpWI 143–146; WI 85–95 (Three workers measured).
Workers with pronounced size polymorphism.
Scape reaching posterior corner of the head in large workers.
In lateral view, pronotum and mesonotum forming a single convexity; propodeum slightly raised relative to promesonotum. Anterior margin of pronotal collar slightly concave in dorsal view. Metanotal groove not convex posteriorly in dorsal view, not very deep and situated posterior to the posterior ridge of pronotum in lateral view; thorax not strongly constricted in middle in dorsal view. In dorsal view, many longitudinal rugulae connecting between mesonotum and propodeum; but 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.
Postpetiole slightly bilobed behind without longitudinal median sulcus.
Clypeus sculptured with longitudinal rugulae. Longitudinal rugulae on dorsal face of head, pronotum, mesonotum and propodeum.
Standing pilosity sparse on dorsal face of head and mesosoma. Dorsal face of head with appressed setae. Fourth abdominal tergite with some erect setae and abundant appressed setae.
Body color black.
