Notes and new taxa in Acanthoderini (Coleoptera: Cerambycidae: Lamiinae). V. Three new genera and notes on Irundisaua.

Generic characters of Irundisaua Martins & Galileo, 2005 are expanded (antennal formula, width of prosternal process inferior or equal to the diameter of procoxa, protibia enlarged and flattened) and two species are transferred from Acanthoderes Audinet-Serville, 1835: I. forsteri (Tippmann, 1960) comb. nov from Peru and Brazil (Amazonas) and I. ucayalensis (Tippmann,1960) comb. nov from Ecuador, Peru and Brazil (Amazonas).Three new genera are described: (1) Catuana gen. nov., type species, C. spinicornis (Tippmann, 1960) comb. nov, characterized by the mesosternal tubercle; (2) Mundeu gen. nov, type species, M. maculicollis (Bates, 1861) comb. nov, with rounded sides of protorax and expanded protibiae; (3) Urangaua gen. nov, with eyes divided and finelly granulated, length of antenomeres III-IV subequal to V-XI; the genus is proposed of two species: U. analis Melzer, 1935 comb. nov, type species, and U. subanalis (Zajciw,1964) comb. nov. A key to the species of Urangaua is added.

A remarkable new species of flesh-fly mimicking weevil (Coleoptera: Curculionidae: Conoderinae) from Southeastern Brazil

Timorus sarcophagoides, new species (type-locality: Brazil, Minas Gerais, Santana do Riacho - Serra do Cipo, 43 degrees 35'W 19 degrees 17'S, 1200-1300m ASL), is described and illustrated. The new species can be distinguished mainly from the other species of the genus by the sexual dimorphism of the male rostrum armed with a hooked tubercle at the base of the dorsal carina, while the tubercle is absent in the female and the corresponding region of the carina is only tumid. The new species has a striking pattern of coloration and behavior that mimics flesh-flies in the family Sarcophagidae. Observations on the natural history of the new species are reported and discussed.

A new species of the Bokermannohyla circumdata group (Anura: Hylidae) from southeastern Brazil, with bioacoustic data on seven species of the genus

We describe a new species of the Bokermannohyla circumdata group from the Estacao de Pesquisa e Desenvolvimento Ambiental Galheiro (EPDA-Galheiro) (19 degrees 12'S; 47 degrees 08'W), Municipality of Perdizes, State of Minas Gerais, a mid-altitudinal (similar or equal to 850 m above sea level) riparian forest environment in the Cerrado of southeastern Brazil. Bokermannohyla napolii sp. nov. is allied to the large-sized species of the group, diagnosed on the basis of adult morphology/morphometrics, and mainly vocalizations. Adult specimens of the new species are most closely related to those of B. luctuosa and B. circumdata, but can be differentiated from the former by having distal subarticular tubercle of finger III bifid/divided in males, and finger IV bifid/divided in males and females; and from both B. luctuosa and B. circumdata by a distinctive advertisement call structure. We also provide bioacoustic data on seven other species of the genus, including previously unknown advertisement calls of B. circumdata and B. carvalhoi, and re-description of the advertisement calls of B. luctuosa, B. ibitiguara, B. nanuzae, B. sazimai, and B. hylax.
