Introduction

Cylindrosella currently contains one described (Barber, 1924) and two undescribed species found in North America. The type species, C. dampfi, was collected on a polypore fungus, Fomes pinicola, at 3200 meters in Mexico.

Ptiliid species generally possess varying spermathecal designs, but striking similarities exist between C. dampfi and an undescribed species occurring in southwestern United States.

Characteristics

Cylindrosella can be separated from other ptiliid genera by the elongated, moderately narrow form (Barber 1924, Dybas 1990). Body length can be up to five times as long as wide. The mesosternal process is directed posteriorly, and generally 'arrowhead-shaped.'

The larva illustrated by Barber (1924: plate 7) as possibly representing Cylindrosella more than likely belongs to the Staphylinidae (Dybas, 1976:50). Ptiliid larvae lack eyespots (exception Nossidium), and larvae of Nanosellinae do not posses urogomphi.

Geographical Distributions

Cylindrosella dampfi is currently known only from the type locality in Mexico. Two undescribed species occur in the western (Arizona, New Mexico) and eastern (Illinois, Michigan, Indiana, Kentucky) regions of the United States, associated with the fungus Fomitopsis pinicola.

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.
