Introduction

Cephalochrysa has 4 species in the Nearctic, 8 in the Afrotropical, 3 in East Asia, 6 in Australia. C. texana is found in the USA and Mexico, and C. stenogaster is found in Japan and Taiwan (Woodley 2001).

Characteristics

Cephalochrysa can be distinguished from other Nearctic Sarginae except Microchrysa by the bare eye, the distal projection on the calypter, and the equilateral ocellar triangle near posterior margin of head. It can be distinguished from Microchrysa by the large d cell, M1 and M2 clearly ending in the wing margin, and cell cup two-thirds as long as the basal cells (James 1981).

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.
