Pinkfloydia is a genus of small Australian long-jawed orb-weavers, reaching a maximum lengths of about 4.5 millimetres (0.18 in).

It was first described by D. Dimitrov & G. Hormiga in 2011,[2] and contains two species, found in New South Wales and Western Australia: P. harveyi and P.

P. harveii is a species of tiny brown spiders, with individuals ranging from 2.75 to 4.5 mm (0.11 to 0.18 in) in total body length, with females reaching larger maximum sizes than males.

[3] The elevated protuberance is unique among tetragnathid spiders, and other unusual features of the male pedipalps warranted the designation of a new genus with a name evocative of its uniqueness: Pinkfloydia was named by biologists Dimitar Dimitrov and Gustavo Hormiga after British rock band Pink Floyd, noting "In its heyday Pink Floyd was an innovative group that created music which was an eclectic mixture of styles... Pinkfloydia has very unusual morphological features and its name aims to reflect its uniqueness.
