    Abstracts

    Alpaida guto n. sp. is described based on males and females from State of Pará, Brazil. This species appears to be the most abundant Alpaida O. P.-Cambridge, 1889 species in Caxiuanã National Forest, eastern Amazonia. The males seem to be close to A. antonio Levi, 1988 but can be easily distinguished by the terminal apophysis with rounded distal lobe and long, slender basal prong; females differ from those of A. yotoco Levi, 1988 by the median lobe with a basal constriction and by the bilobed median plate.
