Oh my goodness! Unless you are a Tree of Life developer, you really shouldn't be here. This page is part of our beta test site, where we develop new features for the ToL, often messing up a thing or two in the process. Please visit the official version of this page, which is available here.

Throscidium

W. Eugene Hall
Containing group: Nanosellini

Introduction

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).

Characteristics

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.

Geographic Distribution

Matthews (1872) described two species, T. fairmairei and T. germainii, from Chile.

This page is a Tree of Life Branch Page.

Each ToL branch page provides a synopsis of the characteristics of a group of organisms representing a branch of the Tree of Life. The major distinction between a branch and a leaf of the Tree of Life is that each branch can be further subdivided into descendent branches, that is, subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
