Justification
This species is listed as Least Concern. As with all species in the genus, its distribution is broad and patchy. However, the species does occur in habitats that are often not studied. It is not impacted by any major threat processes and appears to be locally abundant. It is unlikely to be undergoing significant declines due to habitat degradation, as it appears to utilise a number of habitat types.
