(after Framenau & Baehr 2016): Tasmanicosa ramosa is very distinctive within the genus due to its opisthosoma pattern, dorsally with light transverse, wavy lines and ventrally with a triangular black patch narrowing towards the spinnerets. Genital morphology of males and females resemble that of T. semicincta in having a very long ventral process of the tegular apophysis corresponding to a very long epigyne; however, the T. semicincta ventral pattern is different consisting of a very restricted dark transverse band behind the epigastric furrow. In addition, the anterior half of the median septum in T. ramosa has a very irregular outline unlike that of T. semicincta.

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.
