Remarks: A widespread and rather variable species that seems to form numerous local populations that show slight morphological differences. When specimens from across the whole range of its distribution are compared these morphological differences intergrade and I prefer to consider all of the examined populations conspecific. The workers of P. cryptoceroidesHNS superficially resemble those of Cataulacus and they are often seen foraging together on the trunks of rainforest trees.
