Containing group: Histeridae


Species of Paromalini are small, poorly known histerids. Many in the New World tropics are associated with dead or dying wood. Many occur under bark or are associated with rotting cactus. Species of Carcinops are especially common in the latter situation, although one species, C. pumilio, prefers dung, and has proven useful in poultry houses to aid in fly control (Peck & Anderson, 1969).


Most species of this group are small (<4mm), slightly to extremely (Platylomalus) flattened, and brown to black (some Carcinops are metallic blue or green). They possess labral setae, outwardly arcuate antennal club annuli, and have a pronounced prosternal lobe which does not extend laterally to cover the antennal cavities, and which bears lateral notches which receive the large protibial spur when the legs are retracted.

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.
