[8][5] It can be distinguished from other members of the genus by its long thin palpal bulb, which has a tubercle at the very end, and short embolus.

The epigyne is small with a flat plate and the rear sclerotized, with widely separated copulatory openings.

Many other examples were found across the reserve, in a range of habitats including Acacia senegal woodland, Combretum bushland and grassland.
