Pinkfloydiais agenusof smallAustralianlong-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 inNew South WalesandWestern Australia:P. harveyiandP. rixi.[1]They have a unique rounded, cone-shaped head structure with one pair of large eyes and three pairs of smaller eyes. The genus is named after British rock bandPink Floyd.
Description
[edit]P. harveiiis 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. Theeight eyesare situated on an elevated, rounded protuberance of thecephalothorax,with a one pair of eyes (the posterior median eyes) greatly enlarged compared to the other three pair.[3]The elevated protuberance is unique among tetragnathid spiders, and other unusual features of the malepedipalpswarranted the designation of a new genus with a name evocative of its uniqueness:Pinkfloydiawas named by biologists Dimitar Dimitrov and Gustavo Hormiga after British rock bandPink Floyd,noting "In its heyday Pink Floyd was an innovative group that created music which was an eclectic mixture of styles...Pinkfloydiahas very unusual morphological features and its name aims to reflect its uniqueness. "[3]: 754 The species nameharveiihonors biologist Mark S. Harvey of theWestern Australian Museumwho collected specimens as early as 1990, including theholotypespecimen, the primary specimen used in describing the species.[3]: 756, 763–64
Distribution and ecology
[edit]P. harveiiis known from coastal areas of the state ofWestern Australia,with a range extending fromLesueur National Parkin the northwest toBremer Bayin the southeast.[3]: 763–64
The natural history ofP. harveiiis poorly known. Horizontalwebsof juveniles have been described, measuring 50–90 mm (2.0–3.5 in) wide.[3]
Classification
[edit]Pinkfloydiais a member of theTetragnathidae,a globally distributed family containing around 1,000 species with about 30 species in Australia. Based on morphological, behavioural, and DNA similarities,Pinkfloydiais classified within a group of tetragnathids native to Australia and New Zealand known as the "Nanometaclade ", which includes species ofNanometaandOrsinome sarasini.[3][4][5]
