Oliveira Cardoso da Silva,Leonardo | Lopes,Sonia
This contribution describes and illustrates the male genitalia of two new species of Blaberidae collected in the state of Minas Gerais, Brazil: T. caldensis sp. n. resembles T. neospectrum Lopes, 1978, differing in the coloration, size and genitalia; and T. morroferrensis sp. n., which resembles T. guttulosum (Walker, 1868) but also differs in the size and coloration of specimen and genital pieces morphology. The genital plates were removed after dissection of the posterior part of the abdomen, and were stored in microvials containing glycerin, attached to the respective exemplar in the collection of the Museu Nacional of Rio de Janeiro, Brazil. A key to males of the species of the genus is also presented. Illustrations of T. neospectrum and T. guttulosum are provided to clarify the comparisons with the new species described here.
