Containing group: Pelegrina

Introduction

Like helenae this species has genitalia unusual for the genus, with the erect portion of the embolus arising retrolaterally and the epigynal flaps far rotated. Differs from helenae in having a sharp pointed embolus, short tibial apophysis, and flaps rotated only 180°.

Natural History

Collected from sand prairie (Minnesota, 1 record), from Hymenoeloea (New Mexico, 1 record), ponderosa pine (Arizona, 2 records), from grass-mesquite (Arizona, 1 record), and beating junipers (1 record, New Mexico) at elevations of 1700 to 2200 m in Arizona, Zacatecas and Durango. Jennings (1973) describes egg retreats of this species in Tragopogon and Pinus ponderosa. Cutler and Jennings (1985) give additional habitat information, and characterize P. arizonensis as a species of grasslands.

Distribution

Minnesota and Alberta south to Zacatecas and Tlaxcala.

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.
