As with other harvestmen, Quindina albomarginis has a small body consisting of a cephalothorax fused with an abdomen, raised on four pairs of long legs.

The mouthparts are known as stomotheca and can chew solid food in contrast to the spiders, order Araneae, which can only suck fluids from their prey.

He lives on the trunk of a tree where he builds a low-walled enclosure with a level floor about 3 centimetres (1.2 in) across out of mud and fragments of bark.

She grabs his cephalothorax and pulls him forward and he everts his penis and transfers a bundle of sperm into her genital pore.

She bends her legs to partially lower her body and extends her ovipositor to the floor of the enclosure and places an egg there.
