Dictyoptera is an insect superorder that includes two extant orders of polyneopterous insects: the order Blattodea and the order Mantodea (mantises). All modern Dictyoptera have short ovipositors and typically lay oothecae. The oldest fossils of Dictyoptera from the Late Carboniferous, referred to as "roachoids" have long ovipositors and did not lay oothecae. The oldest modern oothecae-laying dictyopterans date to the Late Triassic.
Giant cockroaches, or blaberids, are the second-largest cockroach family by number of species. Mostly distributed in warmer climates worldwide, this family is based on the American genus Blaberus, but much of the diversity is also found in Africa and Asia.
Blattidae is a cockroach family in the order Blattodea containing several of the most common household cockroaches. Notable species include:
Ectobiidae is a family of the order Blattodea (cockroaches). This family contains many of the smaller common household pest cockroaches, among others. They are sometimes called wood cockroaches. A few notable species include:
Cryptocercus is a genus of Dictyoptera and the sole member of its own family Cryptocercidae. Species are known as wood roaches or brown-hooded cockroaches. These roaches are subsocial, their young requiring considerable parental interaction. They also share wood-digesting gut bacteria types with wood-eating termites, and are therefore seen as evidence of a close genetic relationship, that termites are essentially evolved from social cockroaches.
Corydiidae, previously known as Polyphagidae, is a family of the order Blattodea (cockroaches). Many are known as sand cockroaches. The family is divided into five subfamilies, comprising some 40 genera. One prominent species is the desert cockroach, Arenivaga investigata.
Blattodea is an order of insects that contains cockroaches and termites. Formerly, termites were considered a separate order, Isoptera, but genetic and molecular evidence suggests they evolved from within the cockroach lineage, cladistically making them cockroaches as well. The Blattodea and the mantis are now all considered part of the superorder Dictyoptera. Blattodea includes approximately 4,400 species of cockroach in almost 500 genera, and about 3,000 species of termite in around 300 genera.
Cockroaches are insects belonging to the order Blattodea (Blattaria). About 30 cockroach species out of 4,600 are associated with human habitats. Some species are well-known pests.
Arenivaga is a genus of sand cockroaches, of the subfamily Corydiinae, in the family Corydiidae. These cockroaches live in sandy soils and dunes in the southwestern United States, Florida and Mexico. Arenivaga comes from the Latin arena meaning sand and vagus meaning wandering.
Holocompsa is a genus of hairy sand cockroaches in the family Corydiidae. It is the only genus in the subfamily Holocompsinae.
Arenivaga bolliana, known generally as the Boll's sand cockroach or Boll's sandroach, is a species of cockroach in the family Corydiidae. It is found in North America.
Blattoidea is a superfamily of cockroaches and termites in the order Blattodea. There are about 17 families and more than 4,100 described species in Blattoidea.
Anaplectidae is a family of cockroaches in the order Blattodea. Previously placed as a subfamily of the Ectobiidae there are presently (2020) two genera and more than 90 described species in Anaplectidae.
Corydiinae is a subfamily of the order Blattodea (cockroaches). Many are known as sand cockroaches. The subfamily, comprising about 20 genera, contains half the genera in Corydiidae. One prominent species is the desert cockroach, Arenivaga investigata.
Eucorydia donanensis is a species of iridescent cockroach in the family Corydiidae. It was discovered on Yonaguni Island of Japan's Ryukyu Archipelago, and was believed to be restricted to that island until its discovery on nearby Ishigakijima Island in June 2022.
Eucorydia miyakoensis is a species of cockroach first discovered on Miyako Island, in Japan's Ryukyu Archipelago, in 2021. It is found exclusively in the forests of Miyako Island, where it lives in the forest floor's leaf litter and humus.
Latindia is a genus of cockroaches in the family Corydiidae. There are about nine described species in Latindia.
