Lateral pronotal area: sculptured only on the dorsal third. Antero-admedian line: absent. Mesoscutum: weakly convex. Parapsidal lines: absent. Sculpture of internotaular area: smooth in poststerior half, reticulate coriaceous anteriorly. Notauli: present, incised. Shape of notauli: dilated posteriorly and acute anteriorly. Outer edge of notauli: medial to axillular carina. Orientation of inner edge of notauli: not converging posteriorly. Length of notauli: half of length of mesoscutum, measured along midline. Length of notaulus / maximum width of notaulus: 2.0-2.9 times as long as wide. Distance between notauli: greater than the broadest part of notaulus. Transscutal articulation: complete.

Diagnosis.

Fidiobia vanharteni is relative morphologically similar to F. hofferi because of fore wings with short, hardly visible marginal fringe, presence of epitorular carina and metascutellum visible in dorsal view, but it can be recognized by its light coloration, faintly banded fore wing (uniformly hyaline in F. hofferi ), and OOL slightly shorter or equal to the ocellar diameter (OOL is equal to about 2 OD in F. hofferi ).
