Alarm communication: a new function for the scent-gland secretion in harvestmen
of the peripampasic track include: (a) representatives of the genus Ceratomontia Roewer 1914 (Triaenonychidae), with one species in the central sierras + Ventania, another one in Tandilia + Ventania + Uruguayan ranges + southern Brazil, and a third one in southern Brazil (Maury & Roig Alsina 1985; Maury 2000), and (b) genus Neopucroliella Roewer 1931 (Gonyleptidae), with several species in the central sierras and one in Ventania (this is the only taxon not yet recorded in Uruguay or Brazil; Acosta 1990).
