Nemastoma dentigerum

Nemastoma dentigerum is a small (1,5-1,9mm) species of harvestmen (Opiliones) in the family Nemastomatidae. It is one of few species that are always entirely black, without white markings, but of the species that do normally carry white markings some rare forms exist without markings too. Even so, the males of this species can be readily identified by a prominent tooth under the femora of the palps.
