Overview

Comprehensive Description

Cheiracanthium C.L. Koch, 1839

The genus is placed by some colleagues in the family Miturgidae Simon, 1886 (see note and references in Platnick 2010). Here we follow Deeleman-Reinhold (2001) and Raven (2009, and references therein) in placing the Eutichurinae with Cheiracanthium in the Clubionidae .

Cheiracanthium

Cheiracanthium is a genus of spiders in the Miturgidae family. Certain species are commonly known as the "yellow sac spider".

Description[edit]

Cheiracanthium are usually pale in colour, and have an abdomen that can range from yellow to beige. Both sexes range in size from 5 to 10 mm. Some yellow sac spiders are attracted to the smell of volatiles in gasoline.[1] Of all "common house spiders", they are the only species whose tarsi do not point either outward (like Tegenaria) or inward (like Araneus), and are therefore easy to identify.

Distribution[edit]

Cheiracanthium is primarily an Old World genus, with many species found from northern Europe to Japan, from Southern Africa to India and Australia. The only known species in the New World are C. inclusum and C. mildei. While the former also occurs in Africa and Réunion, the latter is found in the Holarctic region and Argentina. They can also be found in the lower mainland of British Columbia, Canada [2]

Venom[edit]

Cheiracanthium venom is purportedly necrotic, and it could cause a small lesion in humans. However, the necrotic nature and severity of the spider's bite has been disputed.[3] Because of the possibly necrotic nature of the wound, MRSA infection is a danger and victims are advised to seek medical treatment. Painful bites may be incurred from species such as C. punctorium in Europe, C. mildei in Europe and North America, C. inclusum in the Americas, C. lawrencei in South Africa and C. japonicum in Japan.[4]

Attraction to vehicle engines[edit]

An unspecified Cheiracanthium species is attracted to the smell of petroleum and has caused problems by weaving webs inside the canister vent of particular models of Mazda vehicles, resulting in blockages and build-up of pressure that could potentially cause fuel leakage from the fuel tank and an increased risk of fire. Mazda issued a voluntary recall of Mazda 6 models built between 2010-2012, to fit them with software which would alert drivers if problems were developing.[5]
