 Hentz classified A. sexpunctatus in the <unk> group <unk> , which consisted of jumping spiders whose first pair of legs were the longest , followed by the fourth pair . Later <unk> abandoned this classification , which Hentz himself admitted was " somewhat artificial " . In 1888 , with the recognition of Zygoballus as an independent genus , American <unk> George and Elizabeth <unk> renamed the spider Zygoballus sexpunctatus . Specimens of Z. sexpunctatus are housed at the Museum of Comparative <unk> , the British Museum , the Milwaukee Public Museum , the American Museum of Natural History , and the <unk> National d <unk> <unk> . No type specimens are known .
