Specimen Labels

Biological details for Crematogaster ampullaris are available from specimen labels of a Sabah collection (CASENT0193577): workers were found in rainforest in low vegetation.


A member of the Crematogaster inflata species-group. Hosoishi and Ogata (2009) - This species is very similar to Crematogaster sewardi, but can be distinguished by the dorsal outline of the mesosoma and the depth of the metanotal groove.

  • ampullaris. Crematogaster ampullaris Smith, F. 1861b: 47 (w.) INDONESIA (Sulawesi). Combination in C. (Physocrema): Donisthorpe, 1932c: 469. Junior synonym of difformis: Emery, 1901g: 574; Wheeler, W.M. 1919e: 74. Revived from synonymy: Donisthorpe, 1932c: 469. See also: Hosoishi & Ogata, 2009a: 3; Hosoishi & Ogata, 2009b: 19.

Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.



Hosoishi and Ogata (2009) - HW 1.12–1.34; HL 1.04–1.28; CI 100–108; SL 0.95–1.02; SI 76–84; EL 0.22–0.24; PW 0.66–0.82; WL 1.26–1.48; PSL 0; PtL 0.34–0.48; PtW 0.28–0.34; PtH 0.19–0.24; PpL 0.24–0.28; PpW 0.29–0.36; PtHI 50–56; PtWI 71–84; PpWI 117–129; WI 93–106 (Three workers measured).

Workers with pronounced size polymorphism.

Scape not reaching posterior corner of 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 convex posteriorly in dorsal view, deep and situated posterior to the posterior ridge of pronotum in lateral view; thorax strongly constricted in middle in dorsal view. In dorsal view, some longitudinal rugulae connecting between mesonotum and propodeum; the boundary distinct except for median portion. Propodeal spiracle situated away from the metapleural gland orifice, the distance between them much greater than the propodeal spiracle diameter. Propodeal spines absent.

Clypeus sculptured with longitudinal rugulae.

Standing pilosity sparse on dorsal face of head, abundant on promesonotum. Dorsal face of head with decumbent setae. Clypeus with short setae. Dorsal setae on fourth abdominal tergite appressed and directed posteriorly.

Body color reddish brown to black.

Type Material

Hosoishi and Ogata (2009) - INDONESIA: Tondano, Sulawesi [types not found in The Natural History Museum or Oxford University Museum of Natural History]. We have not been able to examine the types of ampullaris. According to Mr. Barry Bolton (pers comm Jan 2008), a search in the collection of BMNH and OXUM revealed that types of C. (P.) ampullaris were no longer present. But the original description and Donisthorpe’s key (1941) closely match the specimens examined.

The following notes on F. Smith type specimens have been provided by Barry Bolton (details):


Donisthorpe (1932c) records two worker syntypes in Oxford University Museum of Natural History. Labelled “Tond.” This material could not be detected in the current survey. Also, no specimens in The Natural History Museum.
