This tree diagram shows the relationships between several groups of organisms.

The root of the current tree connects the organisms featured in this tree to their containing group and the rest of the Tree of Life. The basal branching point in the tree represents the ancestor of the other groups in the tree. This ancestor diversified over time into several descendent subgroups, which are represented as internal nodes and terminal taxa to the right.

Containing group: Gondwanalox clade


Abacetini is a group of probably more than 500 species for which there is little modern synthesis or taxonomic revision. The group is distributed throughout Africa and into southern Europe, across tropical and subtropical Asia and into the Pacific as far as northern Australia. 


A broad set of taxa have been informally associated with Abacetus based on the combination of the lack of the angular base of stria 1; a single pair of deeply impressed, linear basal impressions of the pronotum; a single or no dorsal puncture on the third elytral interval; the basal elytral puncture at or near stria two and males with symmetrically expanded protarsomeres. Additionally, nearly all of these taxa have deeply impressed, elongate frontal impressions on the head; sinuate anterior coxal sulcus and coiled spermatheca.The most obvious characteristic and likely synapomorphy for a possibly dervied clade (Abacetini s.str.) is the eccentrically inserted second antennomere and, perhaps, the strongly transverse mentum. The mentum form, however, is somewhat variable. DNA sequence data also supports this clade based on a selected set of exemplars and several gene loci (K.Will unpublished).

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.
