Abstract:
A remarkable "ancient" cockroach from Brazil (Insecta: Oothecariformia: Blattodea: Blattidae: Cryptocercinae). A new cockroach, Eurycanthablatta pugionata n. gen. n. sp. is described for the first time. The material was collected in Brazil near Manaus. The new species exhibits a sexual dimorphism previously unknown in Blattodea: The males bear a large metafemoral spine. This genus and species is the basalmost representative of Lamproblattini. The monogeneric tribe Cryptocercini with the only genus Cryptocercus Scudder, 1862 is transferred into Lamproblattini because of similar genitalic characters. The type material is housed in the Instituto Nacional de Pesquisas da Amazonia (INPA), Manaus, Brazil, and in the collections of Ingo FRITZSCHE (Wernigerode) and Oliver ZOMPRO (Kiel)
