A common and widespread jumping spider in most habitats along coastal eastern Australia including Tasmania. It is a flattish jumper with rather chubby front legs. The female has obvious white hairs on the pedipalps and a strong, yellow-banded pattern at the rear of the upper surface of the abdomen. Male subadults have horizontally banded palps. It displays a creeping cautious behaviour, often twisting the cephalothorax one way or the other while the abdomen remains stationary. In 1989 Val Davies and Marek Zabka felt this spider was not a true Breda, the other species of which come from South America, so they labelled it incertae sedis meaning not certain in its generic placement. In 2013 Ruiz and Brescovit revised the genus, giving the Australian representative a new home in Ocrisiona, pending further revision. Interestingly, jovial means pertaining to Jupiter, the Roman god of the sky. It was believed those born under the sign of the planet Jupiter are of merry dispositions. 1794.♀ 6mm ♂ 4mm
