Description
Admestina are small and flat, typically measuring less than 4.5 mm in length. Their flattened cephalothorax may help them to hide within crevices on trees. The first legs are the stoutest, with the tibia thickened in both sexes. The three species are all similar in appearance and best distinguished by their geographic range and genitalia.[3]
