Distribution. Brazil, state of Minas Gerais.

Etymology. The new species is named in honor of the Brazilian entomologist, Catarina Macedo Lopes, for her great contribution to medical entomology.

Specimens examined. BRAZIL, Minas Gerais, Mariana, cave “GS-41”, 06–16.VI.2011, Bessi et al. leg., holotype, 1 male, [MNRJ]; Rio Acima, cave “qdf_cpmt_ca3_cav0007”, 29.III–01.IV.2011, Andrade et al. leg., paratype, 1 female.

Discussion. Phasmatocoris catarinae sp. nov. can be readily separated from other species of the genus by its larger size: while length of other Phasmatocoris species ranges from 6 to 20 mm ( Wygodzinsky 1966, Gil-Santana et al. 2007, Pape 2013), the total length of P. catarinae sp. nov. is 22.2–24.0 mm. The conspicuous markings of the body ( Figs. 17–22, 24 , 39–41 ) is another feature that readily distinguishes P. catarinae sp. nov. from all other congeners.
