The monophyly of several cockroach families and subfamilies is doubtful, and the relationships among cockroach lineages are still very much debated. One of the most controversial issues is the position of the genus Cryptocercus, which has generally been considered an isolated lineage most closely related to blattid cockroaches (e.g., McKittrick 1964, Kambhampati 1996, Klass 1997, 2001). Grandcolas (1994), however, argues that Cryptocercus is derived from within the Polyphagidae.

Containing group: Dictyoptera

Introduction

Under bark, or logs, some are arboreal, some live in caves; others in bathtubs and behind bookcases. Some are omnivores; others eat wood.

Upper Carboniferous to Recent. One of the dominant groups of the late Palaeozoic.

Characteristics

• eggs usually contained in ootheca
• leathery forewings.
• male genitalia asymmetrical
• cerci variable, with one or more segments

Other Names for Blattaria

• Blattodea
• roaches
• Cockroaches
