We describe Avima anitas sp. nov. based on material collected in the Brazilian state of Roraima, representing the first record of Agoristenidae in the State. The new species differs externally from other species of Avima by presenting one proximal tubercle on the mesal face of the male cheliceral segment II and a pair of dark spots partially covering mesotergal area III-IV. The genital differs from other species by the ventral small setae of the ventral plate, which are trifid instead of uniramous or bifid.
