Abstract

A previously unreported radiation of myrmarachnine jumping spiders from New Guinea is described, which, although having few known species, is remarkably diverse in body forms. This clade is the new subtribe Levieina, represented by seven new species in three new genera. Within Leviea gen. n. are three new species, L. herberti sp. n., L. lornae sp. n., and L. francesae sp. n., all of which are unusual among the myrmarachnines in appearing as typical salticids, not antlike. Papuamyr gen. n. superficially resembles Ligonipes Karsch, 1878 or Rhombonotus L. Koch, 1879 as a compact antlike spider, but lacks their laterally-compressed palp and bears an ectal spur on the paturon of the chelicera. Two species of Papuamyr gen. n. are described, Papuamyr omhifosga sp. n. and P. pandora sp. n. Agorioides gen. n., containing A. cherubino sp. n. and A. papagena sp. n., is antlike, with the carapace sunken inwards (concave) between the posterior lateral and posterior median eyes. Phylogenetic analysis of data from the 28S, 16SND1, and COI gene regions of 29 species of myrmarachnines shows that the three new genera form a clade that is sister to the subtribe Myrmarachnina (Myrmarachne sensu lato), with the subtribe Ligonipedina less closely related.
