Etymology. The specific epithet is taken from the Latin adjective furcatus , and means fork-shaped, referring to the embolus with an apophysis basally and looked fork-shaped in the lateral view.

Diagnosis. This new species can easily be separated from other congeneric species by the fork-shaped embolus.
