Acropsopilio chilensis Silvestri, 1904 (Eupnoi: Caddidae: Acropsopilioninae), is recorded for Robinson Crusoe Island, Chile. This is the first harvestman species recorded for the Juan Fernandez Archipelago and also the first extra-continental record for this species. During the comparison with continental co-specific specimens some previously unknown, remarkable morphological characteristics were accessed, among them: the absence of ovipositor seminal receptacles and tracheal system, small and imperforate spiracles and the presence of a subdistal spiny stylus in the major branch of the penis.
