Introduction
This species was redescribed by Cannon & Sewell (2001) from material collected from species of Cherax from eastern Australia, and has a very widespread distribution throughout freshwater systems in Australia.
Specimens of T. minor have also been recorded from South Africa and Japan, where hosts are under aquaculture. Molecular data has been used (Chiesa et al. 2015) to attribute unidentified specimens of temnocephalans, found on Cherax destructor Clark, 1936 collected in freshwater ecosystems in Italy, to T. minor; the authors did not recover 100% identity of the sequence data with that of known specimens of T. minor, however, the sequences of the Italian material formed a well-supported clade with the known specimens.
