(after Wesołowska 1999): This species is closely related to M. brevibulbis, M. brachygnathus and M. fulvus. The male may be recognized by the narrower bulbus, shape of the tibial apophysis and the embolus with less bent end. Females of these species have identical form of the epigyne and are impossible to tell apart based on morphological features.

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.
Menemerus bivittatus is similar to, and often found together with M. nigli. Both are typical synanthropic species, i.e. they occur frequently in and around houses on walls and fences. However, they distinctly differ in gential morphology of both males and females and also body colouration, specifically the colour pattern of the abdomen. The embolus of the male pedipalp in M. nigli is much longer than that of M. bivittatus. The female epigyne of M. nigli has characteristic rounded edges internally and a poorly defined anterior margin; in contrast, the M. bivittatus epigyne lacks the internal edges but has a well-defined anterior margin consisting of two arches.
