Malpighian tubule
A tubule that extends from the posterior part of the digestive tract which absorbs solutes, water, and wastes from the surrounding hemolymph. Each tubule consists of a single layer of cells that is closed off at the distal end with the proximal end joining the alimentary canal at the junction between the midgut and hindgut[WP,modified].

It is unclear as to whether the Malpighian tubules of arachnids and those of the Uniramia are homologous or the result of convergent evolution.[Wikipedia:Malpighian_tubule_system]
