Enoplognatha bidens female, dorsal (WAM T171364; Arthur River, Western Australia)

Fauna Portal Image No. 11923Diagnosis
The female of Enoplognatha bidens can be easily distinguished by the spiralling spermducts of the epigyne that are visible through the integument.
The specimen illustrated here was identified based on comparison with a syntype of the species housed at the WA Museum.
(after Dupérré 2023): The syntype specimens of Enoplognatha bidens do not present the typical internal genitalia conformation found in the genus, two large spermathecae, and short copulatory ducts. The female has rather small spermathecae and extremely long and coiled copulatory ducts. The species’ placement in the genus Enoplognatha is considered doubtful but the species cannot be placed in any other genus at this time.

Fauna Portal Records
The map shows all records that have been verified as part of the Fauna Portal project and may not represent the true distribution of a species. Specifically, for described species, check the link to the Atlas of Living Australia on this page for potential wider distributions. Fauna Portal Reference specimens and Linnean types are shown in red. If you identified a specimen that exceeds the distribution of an undescribed species as illustrated here, please contact the Fauna Portal team who can assist with the lodgement of the specimen in a public institution and display on the map.
