The morphological ontogeny of Caleremaeus monilipes (Michael 1882), the type species of CaleremaeusBerlese, 1910, is described and illustrated. The nymphs of this species are quadrideficient and eupheredermous, i.e. they carry the exuvial scalps of previous instars on the gastronotum, using a cornicle. The nymphs have also a posterior apophysis, with setae h1 and p1.
