Abstract:We present the first record for the genus Psalmopoeus Pocock, 1895, in Brazil. A female of Psalmopoeus irminia Saager, 1994, was collected in Pacaraíma, state of Roraima, Brazil. This country now has records of all New World tarantula genera of the subfamily Aviculariinae.

We present the first record of Siphlophis compressus from the state of Roraima, Brazil. This report, from the Serra do Tepequém, extends this species' distribution in Brazil by 789 km to the northwest of the nearest previous locality recorded (Manaus, Amazonas, Brazil).
