Pinkfloydia is a genus of small long-jawed spiders (family Tetragnathidae) containing a single described species, Pinkfloydia harveii, known from Western Australia. Individuals reach maximum lengths of 4.5 millimeters (less than 0.2 inches) and have a unique rounded, cone-shaped head structure with one pair of large eyes and 3 pairs of smaller eyes. The genus is named after British rock band Pink Floyd.
P. harveii is a species of tiny brown spiders, with individuals ranging from 2.75 to 4.5 millimeters in total body length, with females reaching larger maximum sizes than males. The eight eyes are situated on an elevated, rounded protuberance of the cephalothorax, with a one pair of eyes (the posterior median eyes) greatly enlarged compared to the other three pair. 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.":754 The species name harveii honors biologist Mark S. Harvey of the Western Australian Museum who collected specimens as early as 1990, including the holotype specimen, the primary specimen used in describing the species.:756,763–64
Distribution and ecology
Pinkfloydia is a member of the Tetragnathidae, a globally distributed family containing around 1,000 species with about 30 species in Australia. Based on morphological, behavioral, and DNA similarities, Pinkfloydia is classified within a group of tetragnathids native to Australia and New Zealand known as the "Nanometa clade", which includes species of Nanometa and Orsinome sarasini.
