Rediscovery of the forgotten Paraluederwaldtia bituberculata (Mello-Leitão, 1922) (Opiliones: Gonyleptidae) and a review of the relationships of the genus Paraluederwaldtia Mello-Leitão, 1927

Abstract

ABSTRACT Paraluederwaldtia Mello-Leitão, 1927 has its complex historical background herein revised and its position inside Pachylinae Sørensen, 1884 evaluated by cladistic analysis. Based on the results yielded here, Paraluederwaldtia is represented by two species [Paraluederwaldtia ankeri sp. nov. and Paraluederwaldtia bituberculata de Mello-Leitão, 1922 (type species)] endemic to the Atlantic province of Rio de Janeiro, Brazil. Due to the closer relationship of Paraluederwaldtia and the DRMN (Discocyrtus, Roweria, Mitobates and Neopachylus) clade to the detriment of the Pachylinae sensu stricto concept, its removal from Pachylinae is herein proposed. The type locality of P. bituberculata (Alto da Serra, São Paulo, Brazil) is here considered doubtful, and a male neotype from Itatiaia, Rio de Janeiro, Brazil is herein designated. Finally, to address some genera already excluded from Pachylinae and more related to Discocyrtus s. str. than the other DRMN members, the concept of Discocyrtus sensu stricto+ (without formal subfamiliar status) is herein proposed. http://www.zoobank.org/urn:lsid:zoobank.org:pub:1BE09C2C-3855-4BE7-8D43-1640734BB7CC
