Containing group: Clinidium


Protainoa is a monotypic subgenus with one species from western Cuba.


The antennal stylet is long, slender, and acuminate. Tufts are present on antennal segments VI-X. There are one or two temporal seta. The orbital groove is abbreviated posteriorly. The marginal groove of the pronotum is single. Angular and marginal setae are absent. The pronotum is elongate and narrowed anteriorly. The hind angle has a prominent tooth preceded by a pollinose pit. Sutural, parasutural, and intercalary striae are impressed and coarsely punctate. The remaining striae are reduced to rows of fine punctures. The metasternum and abdominal sterna I-III are occupied by a broad medial concavity. The female has enlarged lateral pits on sternum IV. The male's anterior trochanter is dentate. All femora of the male are tuberculate ventrally. The male has an inconspicuous ventral tooth on the anterior femur, and the base of the anterior tarsus is distad to the cleaning organ. The calcars are small, the middle one is longer, more slender, and more acute than the hind one.

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.
