Etymology. The specific name comes from the Latin word imbrex (roofing-tile), referring to the shape of one of the tegular apophyses noun in apposition.

Diagnosis. This new species can be easily distinguished from other members of this genus by the unique imbricate tegular apophysis of the male palp and the shape of the epigynum.
