Synonyms

Crematogaster laeviceps is the most common species of Crematogaster found in the southwest of Western Australia. It nests arboreally and is ubiquitous in nearly all environments (Heterick, 2009).

Wheeler (1934) collected many workers and queens of this ant near Government House, on Rottnest Island, under bark of large Callitris robustai trees and running in files on their trunks, near White Hill, under stones, near Longreach Bay, under stones, and Serpentine Lake, on the trunks of wattles and nesting under their bark.

Type Material

Taxonomic Notes

Heterick (2021): Crematogaster laeviceps broomensis appears to represent no more than an ergatoid of C. laeviceps with vestigial ocelli and an indentation that represents the pronotal suture, whereas the AntWeb image of the C. laeviceps syntype is smoother and shinier and lacks the promesonotal sculpture and hint of a suture. This feature seems to vary with size and possibly also with populations. The AntWeb imaged type specimen of Crematogaster laeviceps chasei, despite Forel’s comments, is indistinguishable from the ant bearing the senior name. Crematogaster laeviceps chasei and C. laeviceps broomensis become junior synonyms under C. laeviceps in this work.
