Mexiclinidium is a moderately sized subgenus with 10 species from Mexico and Guatemala.


The antenna has a small stylet, and there are tufts on antennal segments VII-X. There is one temporal seta. The eye is narrow and crescentic. The orbital groove is complete. The pronotum has a double or single marginal groove. The angular seta is present (except in C. newtoni), the marginals are absent.

(A) Dorsal aspect of head and pronotum of Clinidium (Mexiclinidium) blomi. (B) Right half of the female's sterna IV-VI of Clinidium (Mexiclinidium) triplehorni. (C) Anterior leg (excluding tarsus) of a male Clinidium (Mexiclinidium) iviei. Modified from Bell and Bell (1985). Copyright © 1985 Ross T. Bell and Joyce R. Bell.

The elytral striae are complete, not abbreviated. Excluding the marginal, there are 5 or 4 striae. The intercalary ends blindly posteriorly, except in C. halffteri and some C. guatemalenum. Intervals are elevated and costate in most species. The elytral setae are more numerous than in Arctoclinidium. The female has an enlarged pit in sternum IV.

The male has a ventral tooth on the anterior femur, and the proximal tooth of the anterior tibia is present or absent. The base of the anterior tarsus is proximad to the cleaning organ. The calcars are small, the hind one is smaller than the middle one.

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.
