Ectobius is a genus of non-cosmopolitan cockroaches once thought native to the Old World and described by James Francis Stephens in 1835,Stephens (1835) Illustrations of British Entomology. Mandibulata. Baldwin & Cradock, London, vol. VII, p. 1–306. belonging to the family Ectobiidae, subfamily Ectobiinae.Cockroach Species File (retrieved 6 January 2021) The oldest known member of the genus, Ectobius antiquus, was described from the Upper Cretaceous strata of the Nenjiang Formation (China). The discovery of 4 Ectobius cockroaches in Colorado dating to 49 million years ago suggests that members of the genus were present in North America in the past before their reintroduction by humans. This genus has been subject to a number of revisions.Bohn, H. 1989: Revision of the sylvestris group of Ectobius Stephens in Europe (Blattaria: Blattellidae). Entomologica Scandinavica, 20: 317–342.
Description
The adult 'cockroaches' reach of length, the basic coloration of their body is mostly brown or yellowish, with a clearer margin.
The females are usually bigger than the males and have shorter wings, while in the males wings cover at least the whole abdomen.
Distribution Species of this genus are mainly present in most of Europe, Africa, in eastern Palearctic realm and the Near East. The "lesser cockroach" (i.e. as found in Britain), previously placed here, is now in the genus Capraiellus.Bohn (2013) In Bohn, Beccaloni, Dorow & Pfeifer. Another species of European Ectobiinae travelling north – the new genus Planuncus and its relatives (Insecta: Blattodea: Ectobiinae). Arthropod Systematics & Phylogeny 71(3): 147.
The genus was long absent from the North American continent until recent re-introductions of some cool-adapted species in the Canadian Maritimes and North Eastern, US.
