Description of Gasterogramma psi nov. gen., nov. spec., particularly characterized by the telopodite of the gonopods being torded about l80°, so that the spermal channel curves along the caudal side of the telopodite towards the lateral side, from where it enters the solenomerite. A further particular feature is the distal prolongation of the prefemur into a separate process. An attempt is made at a correct homologization of the elements of the gonopods. The genus appears to be closely related to Semnosoma Silvestri, 1903, from Chile, and on that account seems to constitute the first clear taxonomic link between the dalodesmid faunae of Australia and South America.
