Type Material

Taxonomic Notes

Heterick (2021): A number of the species described in McAreavey’s Cyrtostigmacros key are separated on the basis of features that seem totally inadequate for the task. Apart from Stigmacros flava, whose workers are uniformly pale, there seem to be only two forms in WA that I have come across, these being S. clivispina, which has a narrow petiolar node and another, light-coloured form that has a broad node which I am calling Stigmacros occidentalis, the earliest name. Stigmacros clivispina can be light or dark coloured or of intermediate colouration, but the head and gaster are virtually always darker than the mesosoma. Lighter-coloured S. clivispina can only be satisfactorily distinguished from S. occidentalis by the shape of the node. Based on my examination of type specimens at ANIC, S. clivispina has at least seven synonyms (i.e. those listed above), all of these being species described by McAreavey. A syntype of Stigmacros castanea was supposedly collected in Mundaring, based on an ANIC record, but McAreavey only mentions seeing eastern Australian material. The specific identity of the syntype is therefore questionable.
