Kipling Will
Containing group: Morionini


This pantropical genus includes 41 named species, though undoubtedly many more remain to be described. Individuals are generally found in rotten logs and under loose bark. They often come to lights and do fly. As far as known they are predatory. Adults produce a potent spray of formic acid from their pygidial glands.


Member taxa are typical of Morionini form, elongate, subpedunculate with moderately prominent temples. Morion species share the synapomorphic characteristics of Morionina but lack the more derived features found in Hyperion, Platynodes and Megamorio. More than half of the described species are treated in keys by Chaudoir (1880) and Allen (1968). Otherwise, regionally specific keys may used, e.g., those by Jeannel (1948), Darlington (1962) and Straneo (1958), but all lack some portion of the described taxa.

Discussion of Phylogenetic Relationships

The genus has been divided by into two subgenera (Jeannel 1948, Straneo 1952); Morion (s.str.) and Morion (Neomorion) Jeannel. A comprehensive study of this genus, especially the African and Oriental species, would be very beneficial. It seems likely that Morion will be found to be a grade at this level and Hyperion, Platynodes and Megamorio may be derived from it.

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.
