Description


It is impossible to differentiate Arachosia magna from other similar species such as Arachosia kapiipeoi by photo alone, unless there is a size reference, as they inhabit the same environments. Adults of Arachosia magna exceed 9 mm in body length (excluding the legs), while the others never reach that size.
