Urogelides daviesae Zabka 2009 Long-tailed Jumping Spider

An unusual spider in open sclerophyll forests dwelling in leaf litter, on vegetation and on Allocasuarina trees. The anal tubercle and posterior spinnerets are exceptionally long and make a kind of movable "tail" as in Uroballus. Unlike Uroballus this spider is unidentate and does not have a square, blocky cephalothorax or massive legs. Its genitals resemble Synagelides, suggesting this spider belongs to the subfamily Heliophaninae. The male cephalothorax is flat, rectangular, generally dark orange when adult. Eye surroundings black, eye field with two black patches. Abdomen with herringbone pattern. Females with egg sacs were found in retreats constructed between fallen leaves wedged in outer forks of coastal Allocasurina. When walking Urogelides "waves" the prominent spinnerets up-and-down at regular intervals. The generic name refers to long, tail-like spinnerets and to the genus Synagelides (possible relative).
