Fauna Portal Image No. 9077Diagnosis
(after Machado 2019): Females of I. cambridgei are similar to those of I. rufiventris, in having an elongated body, predominant orange coloration and obovate opisthosoma. However, they can be distinguished by the prosoma being longer than wide, with two pairs of longitudinal lines (a median pair that runs from the carapace slope until the posterior eye row and a lateral one placed close to the border of the prosoma and limited to the thoracic portion), epigynal plate flattened with depressed atrium, copulatory openings hidden by the lateral folds (like a pair of lateral pockets), and long, coiled and membranous copulatory ducts. Males are easily recognized by their set of modified (long, thin and filiform) barbs on tibiae and metatarsi I and by the remarkably rounded and big pedipalps with a single curved retrolateral tibial apophysis.

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.
