This article describes the clinical progression of symptoms over a period of 5 days of a bite inflicted by a Philodromus sp. spider. Commonly
known as ‘running spiders’, these are not considered to be harmful to humans. This report, however, is the first description of an actual
bite by a member of this group of spiders showing cytotoxic envenomation. Management of the bites should be as recommended for other
cytotoxic spider bites.
