Material examined.

Other material examined.

Etymology.

The specific name is a patronym in honour of Mark A. Newton; a keen invertebrate naturalist who provided life images of jumping spiders for this study and keeps on documenting the amazing wildlife of the Australian outback.

Diagnosis.

Males of Jotus newtoni differ from congeners by the pale-coloured body and pale legs with only a fringe of long, dark setae at leg I; prosoma with a broad lateral band and two broad central bands of white setae (Fig. 11A); embolic disc broad at base, nearly circular with small u-shaped indention prolaterally; and embolus accompanied by a slim, semicircular conductor (Fig. 11F, 12H arrow).
