Gavarilla gen. nov. from Northeastern Brazil is proposed to include two new species: the type species Gavarilla ianuzziae sp. nov. from the State of Sergipe and Gavarilla arretada sp. nov. from the State of Maranhão. The genus presents the standard sitticine dentition and is presumably related to the genera Aillutticus Galiano, 1987, Nosferattus Ruiz & Brescovit, 2005, Capeta Ruiz & Brescovit, 2005 and Amatorculus Ruiz & Brescovit, 2005, with which it shares the similar high, rounded carapace. Two new species, Capeta cachimbo and Amatorculus cristinae, are also described from the State of Pará, and Amatorculus stygius Ruiz & Brescovit, 2005 is recorded for the first time from the State of Minas Gerais.
