We describe three new species collected from the Reserva Ducke (02°55'-03°01'S, 59°53'-59°59'W), near Manaus, state of Amazonas: one new species was included in Blaberidae (Epilamprinae): Epilampra manauara sp. nov: , which is similar to E. sagitta Rocha e Silva & Aguiar, 1978. It differs from that species in the generally darker coloration and the internal genitalia, which has the right phallomere hooked, developed, wide medially and distended apically, bearing an apical spine-like structure and a median sclerite with a larger prepucium, rounded and with apex more sclerotized and with better-defined apical crests. Two new species were included in Ectobiidae (Blattellinae): Chromatonotus amazoninus sp. nov: , which is similar to Chromatonotus caruaruensis Lopes & Khouri, 2009 in the parallel brown marks on the pronotum, but differs in the shape of the subgenital plate, the median sclerite with a more-sclerotized tip, left phallomere with angulate apex (90 degrees) and apex curved, right phallomere with basal stem more slender and with apical arms dilated; and Dasyblatta spiculata sp. nov: , which has an asymmetrical genital plate and the median sclerite shaped as a spine apically, differing from other species of the genus. The specimens were collected in the evening, in leaf litter, from fallen logs, or on branches and foliage. The male genitalia are illustrated and the material studied is deposited in the collection of the Department of Entomology of the Museu Nacional do Rio de Janeiro (MNRJ).
