Resumo: |
Macrobuninae Petrunkevitch is revised and submitted to a cladistic analysis. Macrobuninae, once considered the biggest Amaurobiidae Thorell subfamily is now proved to be not even closely related to Amaurobiinae, the \"true amaurobiids\". Our matrix, composed by 82 terminal taxa and 107 characters, includes representatives of all Macrobuninae genera and new taxa we believed to be part of Macrobuninae. As out-groups, we included representatives of the families Agelenidae Koch, Amaurobiidae, Amphinectidae Forster & Wilton, Chummidae Jocqué, Desidae Pocock, Dictynidae O. P.-Cambridge, Phyxelididae Lehtinen, Stiphidiidae Dalmas, Tengellidae Dahl, Titanoecidae Lehtinen, Zorocratidae Dahl and Zoropsidae Bertkau, which were suggested as related to Macrobuninae by previous studies. Our main results confirm Macrobuninae as not forming a monophyletic group with Amaurobiidae and shows the need to erect Macrobunidae Petrunkevitch, 1928 new rank to include Macrobuninae and relatives. Three other subfamilies are proposed here: Retirinae subfam. nov., Pakehinae subfam. nov., and Zanomyinae Ubick, 2005 new rank. Chummidae, currently composed by one genus and two species, is considered a junior-synonym with Macrobunidae. Amaurobiidae appears as sister group of the \"Oval Calamistrum Clade\" and the \"Fused Paracribellar clade\". The subfamily Macrobuninae is revised at the generic-level and redelimited to include a total of 26 genera. Of those, thirteen are newly described: Siyabonga gen. nov., Peckmaria gen. nov., Ijoubetumsam gen. nov., Imbumbulu gen. nov., Ibhulashi gen. nov., Umunwe gen. nov., Pigozzoi gen. nov., Samadhia gen. nov., Naynay gen. nov., Segoko gen. nov., Deusemais gen. nov., Madiba gen. nov. and Ushaka gen nov.. The remaining known genera are redescribed including their type-species, except the ones with recent, up to date descriptions. Seventeen new species are described: Emmenomma joshuabelli sp. nov., Macrobunus alejandrosanzi, sp. nov., Macrobunus eniomattosi sp. nov., Yupanquia lenktaitisi sp. nov., Ijoubetumsam frizzellae sp. nov., Deusemais viximaria sp. nov., Naynay meikleae sp. nov., Pigozzoi pifozonho sp. nov., Samadhia kellyfujiharae sp. nov., Siyabonga kakhulu sp. nov., Imbumbulu westhuizenis sp. nov., Madiba haddadi sp. nov., Ushaka umsila sp. nov., Ushaka philai sp. nov., Ibhulashi lakeside sp. nov., Umunwe ndabae sp. nov. and Segoko chueneorum sp. nov. Eight genera removed from Macrobuninae are assigned to other subfamilies and/or families. All taxonomic changes are justified by the phylogenetic analysis. For the first time the male specimens of Hicanodon Tullgren, Yupanquia Lehtinen and Chresiona Simon are described; Anisacate fuegianum bransfield Usher is raised to the species level, A. bransfield Usher new rank; Emmenomma beauchenicum Usher is considered junior synonym of E. oculatum Simon; Emmenomma oculatum obscurum Simon is removed from the synonym with E. oculatum and raised to the species level, Emmenomma obscurum Simon new rank. The type specimens of Macrobunus backhauseni (Simon) are considered non co-specifics and a new species Macrobunus alejandrosanzi sp. nov. is described based on the female. The true female of M. backhauseni is described for the first time. Other taxonomic changes include: removal of Notolathys Mello-Leitão from synonymy with Auximella Strand and placement as a junior synonym of Retiro Mello-Leitão; to consider Urepus Roth a junior synonym of Auximella; and Tymbira Mello-Leitão a junior synonym of Metaltella Mello-Leitão |
