- Throscidium germainii
Long considered to be a 'primitive' form of Nanosellinae, Throscidium appears to be related to a complex of nanosellines inhabiting Australia. These large and robust ptiliids inhabit forest floor litter or are associated with fungi in South America (Chile).
Throscidium can be separated from other nanosellines by its large size; 11-segmented antennae; characteristically narrow mesosternal process; pygidial spine similar in shape to that of Porophila; metasternal lines not meeting between metacoxae.
Matthews (1872) described two species, T. fairmairei and T. germainii, from Chile.
