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.


Leoglymmius lignarius

Ross T. Bell
Containing group: Rhysodini


This subtribe of Rhysodini contains one genus, Leoglymmius Bell and Bell, and a single species from Australia, L. lignarius (Ollif). This species occurs in the mountain forests of eastern Australia, from New South Wales to Tasmania. It has been found within Eucalyptus trunks in Moist Eucalyptus Forests, sometimes in the same logs as Sloanoglymmius planatus, but also in drier areas where the latter is thought to be absent.


With 8-10 mm in length, Leoglymmius is large for rhysodines. The antennal segments V-X have many scattered minor setae on the distal half of each segment. The eyes are large and round. The mentum is separated anteriorly from the head capsule by a narrow cleft. Dorsally the head has a shield-shaped median lobe and large convex temporal lobes which have one temporal seta. The prosternum is densely setose medially. The pronotum has complete paramedian grooves which define four broad dorsal carinae. The middle and hind tibiae each have two equal spurs. The elytron has seven punctate striae. The hind wings are present, and this species is probably capable of flight.

Relationship of Leoglymmiina to Other Rhysodines

The broad band of minor setae on each outer antennal segment is a symplesiomorphy with other tribes of Carabidae. All other Rhysodini have these setae either restricted to ventral tufts (Clinidiina) or else forming single bands on each segment (the other five tribes). The cleft between the anterior part of the mentum and the head capsule is a symplesiomorphy shared only with Sloanoglymmiina. At present no synapomorphies are known with other subtribes.

This page is a Tree of Life Leaf Page.

Each ToL leaf page provides a synopsis of the characteristics of a group of organisms representing a leaf at the tip of the Tree of Life. The major distinction between a leaf and a branch of the Tree of Life is that a leaf cannot generally be further subdivided into 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.
