Loxosceles Heineken & Lowe, 1832 - (recluse spiders)

The species of this genus are mainly found in America and are known for their poisonous bites, although they are not aggressive. The bites also vary in severity with some resulting in a small or mild reaction including itchiness and fast healing. In severe cases bites result in necrotic skin lesions which might take months to heal. Very serious reactions are rare, but some deaths of children have been reported.

The body of the adult is brown and around 10 mm long. The cephalothorax has a characteristic violin marking, but such markings can also be found in some other spiders.
