Pelegrina galathea (Walckenaer 1837)

Containing group: Pelegrina

Introduction

A widespread species, formerly confused with others in eastern North America, from which it is distinguished by the embolus shape of males, and speckled abdominal dorsum, annulate legs, and convex epigynal flaps of females. Carapace wider than in most eastern species. Similar especially to the Caribbean proxima and southwestern dithalea. Can be separated from proterva by (males) the narrower embolus with smaller hook, darker face and broader carapace, and by (females) the abdominal markings and convex epigynal flaps.

Natural History

In eastern North America this species is generally found in sunlit places such as oldfields, in contrast to P. proterva which is generally more of a forest dweller. In Chihuahua P. galathea lives in riparian vegetation. Horner (1972) has investigated the bionomics and importance of P. galathea in biological control in sorghum. Steiner and Greenstone (1991) examined segregation of isozyme markers in P. galathea.

Distribution

Eastern North America north to southern Ontario, west to the Rocky Mountains, south to Florida and Costa Rica.

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.
