Abstract

The genus Sphecozone O. P.-Cambridge, 1870 currently includes 34 species and has as type-species S. rubescens. With the exception of a North American species, S. magnipalpis Millidge, 1993, the genus occur only in the Neotropics. Recent studies involving cladistic analysis suggests the monophyly of the genus, which is supported by the loss of paracymbium and radical ridge, and the origin of a atrium, and sets the genus Tutaibo Chamberlin, 1916 as its sister group and related to Ceratinopsis Emerton,1882 Dolabritor Millidge, 1991, Intecymbium Miller, 2007, Gonatoraphis Millidge, 1991 and Psilocymbium Millidge, 1991, based on the absence or modification of paracymbium, structure present on the palp of adult male of Araneoidea superfamily. Nevertheless, the internal relationships and monophily of Sphecozone is still controversial, and hypothesis about revalidation of one of its synonymized genera such as Hypselistoides Tullgren, 1901, Brattia Simon, 1894, Clitolyna Simon,1894, Gymnocymbium Millidge, 1991 are still discussed. In this context, this project intent to review the genus Sphecozone describing probably new species. and test their monophyly through a cladistic analysis, including new terminals. (AU)
