Physical Characteristics

Small species measuring 0.00346-0.00425 in (88-108 pm). Cephalic sensory structures consist of very long primary clavae (longer than the body), two lens-shaped buccal clavae, two long internal and external cirri, two short lateral cirri, and a single, median cirrus. Adults have telescopic legs with lancelike tibia, conic tarsus, and four toes with internal claws with small dorsal spurs; 18-20 balloon-like appendages are attached on the fourth leg pair. Balloons vary greatly in shape, and regulate the buoyancy of animal when it adheres to substrate. Females have two cuticular seminal receptacles that open lateral to the gonopore.
