Fauna Portal Image No. 5167Diagnosis
(after Greenberg et al. 2021): Males of Missulena iugum share the red chelicerae and pars cephalica with M. davidi, M. manningensis, M. langlandsi, M. occataria and M. insignis that are morphologically most similar. They differ from M. langlandsi by a longer carapace (>3.00 mm; M. langlandsi up to 2.8 mm) and a rastellum with strong, conical spines (simple in M. langlandsi). Rastellum and cuspules on labium and maxillae stronger than in M. insignis (rastellum: 8–9 spines; M. insignis 2–5 ;cuspules: M. insignis none). Pars cephalica lower than in M. occatoria (up to1.69; M. occataria approx. 3.0) and carapaceshorter (3.87 long, 4.98 wide; M. occataria approx. 5.0 long, 7.0 wide). Differs from M. davidi and M. manningensis by thepresence of aridge in the cheliceral groove.

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.
