Etymology.

This name originates from the Latin word ‘multi-’ and ‘-fidus’, and the combination means ‘multiply-clefted’, referring to the apex of lamella characteristica; adjective.

Diagnosis.

The new species differs from other congeners by the shape of lamella characteristica (Fig. 81 A–B) and the tip of embolus (Fig. 81 C–D).
