Diagnosis
Differs from other species of the genus by the shape of the postnodal telopodite and by the non-enlarged tubercles on the hypoproct.
Etymology
The name is a Latin noun in apposition, meaning mermaid, and refers to the mermaid tail-like shape of the postnodal telopodite when seen from the mesal side.
