Pristomyrmex tsujii
''Pristomyrmex tsujii'' (named for Prof. Kazuki Tsuji) is a species of ant in the genus ''Pristomyrmex''. Known from Fiji, where they are widely distributed but rarely encountered. The species has a discrete ergatoid queen caste that is intermediate between a worker and an alate queen.
==Habitat and distribution==
Despite being widely distributed across the Fijian archipelago, workers of ''Pristomyrmex tsujii'' are rarely encountered in the field, although males have been collected in Malaise traps with some frequency. Workers have been collected from Gau, Koro, Vanua Levu and Viti Levu. Of these, all were collected in leaf litter samples except for one found foraging on a fallen tree and another found foraging under a stone. Collection records suggest the species prefers primary rainforest, but several collections from secondary forests and forest fragments suggest it can tolerate some degree of disturbance. The strongly distended gasters of the ergatoid queens are presumably equipped with functional ovaries, but a more thorough examination of fresh material would be required to verify their reproductive potential. It is also unknown whether the ergatoid queens occur in the same nests as alate queens, or if they are capable of founding their own colonies.〔
