Comments.

This is the first collection of Thecturota pusio since Casey’s description (1894) based on the female holotype from ‘Indiana’ and the first Canadian record of the genus. We have dissected the female holotype for comparison with the Ontario specimens and illustrate the male and female sexual characters for the first time (Figs 109-115). Live specimens of Thecturota pusio were extremely slow-moving and the use of a Berlese funnel likely facilitated the capture of this minute (<2mm) species.
