Abstract
Urupuyu gen. nov. is described for three new species of small black jumping spiders from the cloud forests of Ecuador: Urupuyu antisana sp. nov. (type species), U. edwardsi sp. nov., and U. occidentale sp. nov. Phylogenetic analyses with DNA sequences (28S, actin 5C, wingless, 16SND1 and CO1) indicate Urupuyu is closely related to the huriine amycoids Hurius and Scoturius, a placement also supported by morphological traits. Our phylogenetic analysis serves to clarify the relationships within the Amycoida in general, leading to our proposing a revised classification for the group, with subfamilies Gophoinae, Sitticinae, Bredinae subfam. nov., Scopocirinae, Thiodininae, Sarindinae, Huriinae, Simonellinae, and Amycinae. We confirm the marpissine-like Breda belongs within the Amycoida. The phylogeny implies that ant mimicry has evolved at least twice (simonellines and sarindines) and probably a third time (Atomosphyrus in the thiodinines) within the Amycoida. The following new synonymies are proposed for suprageneric names: Hyetusseae Simon, 1903 and Arachnomureae Mello-Leitão, 1917 = Thiodininae Simon, 1901; Zunigeae Simon, 1901 = Sarindinae Simon, 1901; Synemosynae Banks, 1892 = Simonellinae Peckham, Peckham & Wheeler, 1888; Magoninae Petrunkevitch, 1928 = Amycinae F.O.P.-Cambridge, 1900.
