Three new species and the first known males of the andean spider genus orinomana strand (araneae, uloboridae)

Abstract

Three new species of the uloborid genus Orinomana Strand, O. penelope n. sp. from Ecuador, O. viracocha n. sp. from Peru, and O. florezi n. sp. from Colombia, are described. Additionally, the male of O. ascha Grismado, from Northwestern Argentina, is described for the first time. This material includes the first males known of the genus, providing diagnostic characters for its recognition; the complex and massive embolus with several branches is proposed as a synapomorphy of the genus.
