All these characters, together with molecular evidence, support the monophyly of thegenus, as well as its placement as sister group of Oonopinae. Most American species of Orchestinainhabit the forest foliage and canopy, but in unforested areas they also occur in shrubs and grasses.In this work, we revise the American representatives of Orchestina in a comprehensive context forthe first time. In the past, six species were known from the Americas: five from the United Statesand only one from South America, described from Venezuela. After the study of the principal collectionsof the world and s
