Silva Junior & R. Bertani (1991) The genus Ephebopus Simon, 1982 Description of the male of Ephebopus murinus (Walckenaer), 1 837 (Araneae, Thera-phosidae, Aviculariinae). -Spixiana 14/3: 245-248. The genus Ephebopus Simon, 1892 which had been included by Raven (1985) in the subfamily Theraphosinae Thorell, 1870 is transferred to the subfamily Aviculariinae Simon, 1 892 based on the comparative study of the characters shown by the genera of this subfamily. We describe the male of Ephebopus murinus (Walckenaer), 1837, col-lected in the State of Para, Brazil. Sylvia Lucas, Pedro Ismael da Silva Junior and Rogerio Bertani, Dept. Biologia, In-stituto Butantan, Av. Vital Brazil, 1 500 Sao Paulo, Sao Paulo, Brasil CEP 05504 Introduction The genus Ephebopus Simon, 1892, was tentatively included by Raven (1985) in the subfamily The-raphosinae Thorell, 1870, although the diagnostic characters of the males were unknown, since the three descnbed species are known only from females. On several expeditions in the Amazonian region of Brazil the authors collected numerous specimens of Ephebopus murinus (Walckenaer), 1837, among them some males which are described in this paper. We also confirm the svnapomorphies of the subfamily Aviculariinae Simon, 1892, having studied species from all genera of that subfamily: Avicularia Lamarck, 1818; Ephebopus Simon, \S92; Iridopelma Pocock, 1901 ; Pachistopelma Pocock, 1901 and Tapinauchenius Äusserer, 1871. Material and Method The material deposited in the Arachnological Collcction of Mygalomorphae and also six still h\ ing specimens >>t the Instituto Butantan were studied. For the polarization of the characters we used the method ot out group com-parison followine Watrous & Wheeler (1981), considering the subfamily Theraphosinae as the out group.
