"Herennia" is a genus of spiders in the Nephilidae family with Australasian distribution. While two species have been known since the 19th century, nine new species were described in 2005. Spiders in this genus are sometimes called coin spiders.

While "H. multipuncta" is invasive and synanthropic, all other known species are endemic to islands.Kuntner, M. (2005). A revision of "Herennia" (Araneae:Nephilidae:Nephilinae), the Australasian 'coin spiders'. "Invertebrate Systematics" 19(5):391-436. [http://www.publish.csiro.au/paper/IS05024.htm Abstract] DOI|10.1071/IS05024]

Like in the related genus "Nephilengys", the much smaller males mutilate and sever their pedipalps, which are often found stuck in female genital openings. Three reasons for this have been proposed: the broken embolic conductors could function as mating plugs, severing the bulb after mutilation could help the male to avoid hemolymph leakage, or the severed male could protect his parental investment by fighting off rival males.

Name

Herennia Etruscilla was the wife of Trajan Decius. There are coins bearing her image, which were probably the source for Thorell to name the genus. The non-scientific name "coin spiders" was proposed because of this fact.
