. The spermophore is meandering. The female is smaller than the male, with a carapace that is typically long and wide and an abdomen typically in length and in width. It is similar to the male in shape, apart from the narrower carapace. The carapace is generally brown, tending to orange towards the edges, but lacks the characteristic bright orange scales of the male. The eye field is dark, nearly black. The abdomen differs from the male in the lack of orange hairs. It is not unusual for the males of the genus to be less ornate that the females. The

s are hidden in sclerotized cup-like regions. Internally, the structure is simple with long thin seminal ducts leading to nearly-spherical receptacles. The spider is typical for the genus. The male can be distinguished from other species by its bright orange scales and the orange hair on the back half of its abdomen. It also has a long dorsal spike on its palpal tibia and an unusual right-angle shaped subtegulum. The female can be differentiated from other ''Asemonea'' spiders by the very simple structure of its epigyne. These contrast heavily with the complex design of other species like '' Asemonea flava''.


Behaviour

Despite being termed jumping spiders, members of the genus ''Asemonea'' rarely jump. Instead, they generally walk and run. They spin sheet webs on the underside of leaves, where they also lay their eggs. Although predominantly a diurnal hunter, the spider is also likely to eat nectar.
