Description

Members of this genus resemble the comb-footed spiders, Theridiidae, due to their globular abdomen. The upper side of this bears curved bristle-like hairs. A distinguishing mark of the genus is that the distance between the anterior edge of the carapace and the anterior medial eyes is about one-third to one-half of the distance between the anterior and posterior medial eyes. The length of the anterior legs is about 1.5-1.7 times that of the posterior pair.[2]

Behaviour

Spiders in this genus are specialised spider killers. They spin no web but are slow moving, stalking or ambushing their prey. They sometimes invade the web of their potential victim, vibrating the silk to mislead the owner. An individual will attack a potential victim by biting one of its legs and injecting toxins. It then retreats and the prey spider quickly becomes paralysed. The attacker then advances and starts to feed, sucking out the body fluids of its victim.[2][3]
