An order of tardigrades, lacking a cirrus lateralis, a sensory cephalic appendage, and a clava, or club-shaped appendage. Pharyngeal pockets are strengthened by separated rods or macroplacoids or are without thickenings. Claws are of different size, arranged in two pairs in which a larger and smaller claw are united. In Milnesium the claws are separated. Haplomacrobiotus has two simple claws. Eight longitudinal muscles are associated with the midgut. At the beginning of the hindgut, there are three excretory glands, called the vasa malpighii, which are specifically stretched or trilobed. Each gland is composed of three cells. The gonoducts open into the rectum, resulting in a single opening known as the anogenital pore or cloaca.
