Griswoldella gen. nov., a new castianeirine spider genus from Madagascar (Araneae: Corinnidae)

The female type of Cetonana aculifera (Strand, 1916), currently a nomen dubium in Trachelidae, is rediscovered, and the species is revalidated, based on a redescription of the female and first description of the male. The new genus Griswoldellagen. nov. is described to accommodate G. aculiferacomb. nov. as its type species, and is placed in Corinnidae: Castianeirinae. The relationships between the Madagascan Griswoldellagen. nov., DisnyssusRaven, 2015 from Australia, and CambalidaSimon, 1909 from the Afrotropics and Indian subcontinent, are discussed within a morphological and biogeographical context.
