About

Armadillidium ruffoi Arcangeli, 1940 is a pill woodlouse of the family Armadillidiidae endemic to northern Italy; all known specimens come from the province of Verona. It belongs to the 'Marginiferae' section of the genus, in which the side edges of the forehead turn up into lobes that form a 'frontal brim' with the frontal shield, and it is thought to be closely related to the probably sympatric A. germanicum, or even to be its southernmost variety. It is medium-sized, reaching about 16 x 6.5 mm. The tergites are shiny, and the body is faded grey with irregular whitish spots arranged in three longitudinal rows, the middle row being the most distinct; the corners of the epimera are also whitish. Almost nothing is known of its ecology, but the type series was collected in and around caves. In Japan it appears only rarely at specialist shops as a display isopod and is mostly searched for by name.
