Arenivaga genitalis
Arizona sand cockroach
Arenivaga genitalis, commonly known as the Arizona sand cockroach, is a species of desert-dwelling cockroach in the family Corydiidae. It is native to the southwestern United States, particularly Arizona and California. Like other members of its genus, it exhibits dramatic sexual dimorphism, with males and females differing substantially in appearance. The species inhabits harsh, arid environments and has adaptations allowing it to thrive in dry conditions atypical for most cockroaches.
Arenivaga sequoia
desert cockroach, sand cockroach
Arenivaga sequoia is a species of desert cockroach in the family Corydiidae, described by Heidi Hopkins in 2014 as part of a major revision of the genus Arenivaga. This species belongs to a group known for remarkable adaptations to harsh, arid environments. Like other Arenivaga species, it exhibits dramatic sexual dimorphism, with females appearing markedly different from males. The species was described based on male specimens, with species separation relying on complex genital characters. It is one of 39 new species discovered during Hopkins' four-year revision, which increased the genus from nine to 48 species.
Corydiidae
Sand Cockroaches, Sand Roaches
Corydiidae is a family of cockroaches in the order Blattodea, commonly known as sand cockroaches or sand roaches. The family was previously classified as Polyphagidae and contains approximately 40 genera divided among five subfamilies: Corydiinae, Latindiinae, Tiviinae, Euthyrrhaphinae, and Holocompsinae. Members are frequently associated with harsh, dry habitats including deserts and arid regions—environments not typically associated with cockroaches. Many species exhibit subterranean habits, making them easily overlooked. The genus Arenivaga (desert cockroaches) is particularly notable, with 39 new species described in a 2014 revision, expanding from 9 previously known species. The family has a worldwide distribution with significant diversity in North America, Asia, and other arid regions.
