Notes.
The new species is similar to

1993
in body coloration, but has the white stripe broader on the vertex and differs from all others of the genus by the slim aedeagal shaft and absence the central lobe of the connective.
Etymology.
The specific epithet is the Latin noun “
gladius
” (sword), which refers to the sword-like aedeagal shaft in ventral view.
