Preocellar depression: absent. Paraocellar depressions: present. OOL / ocellar diameter: OOL equal with ocellar diameter (OOL 1.1 times as long as ocellar diameter). Orientation of lower half of inner orbits: visibly divergent. Sculpture of frons immediately anterior to ocellus: reticulate-coriaceous. Sculpture of frons immediately dorsal to toruli: the same as the sculpture of the rest of frons, but more transverse. Epitorular carina: absent. Distance between toruli: smaller than the transverse diameter of torulus. Setation of clypeus: two setae. Malar sulcus: absent. Antenna (Fig. 41 ). Colour of A1: light brown. Colour of clava: slightly darker than the rest of antenna. Number of antennomeres: nine. Shape of A1: more or less cylindrical. Ventral (inner) lamella on A1: present as a trace in the apical part of A1. Length of A3 of female: distinctly shorter than A2. Sensillar formula (A7:A8:A9): unknown.

Mesosoma (Figs 38 , 42 ). Colour of mesosoma: dark brown. Mesosoma: weakly compressed dorsoventrally. Pronotum in dorsal view: narrow, collarlike. Transverse pronotal sulcus: present as a narrow groove along anterior rim of pronotum. Posteroventral end of transverse pronotal sulcus: dilated. Lateral pronotal area: almost totally sculptured. Antero-admedian line: absent. Mesoscutum: weakly convex. Parapsidal lines: absent. Sculpture of internotaular area: absent. Notauli: present, incised. Shape of notauli: dilated posteriorly and rounded anteriorly. Outer edge of notauli: almost collinear with axillular carina. Orientation of inner edge of notauli: not converging posteriorly. Length of notauli: at most 0.3 times as long as length of mesoscutellum, measured along midline. Length of notaulus / maximum width of notaulus: 3-4 times as long as wide. Distance between notauli: greater than the broadest part of notaulus. Transscutal articulation: complete. Scuto-scutellar sulcus: absent. Fovea on scuto-scutellar sulcus: unknown. Mesoscutellum: weakly convex. Shape of mesoscutellum: subrectangular. Axillular carina: posterior apex of axillular carinae touching the posterior edge of mesoscutellum. Axilloaxillular carina: present. Sculpture of mesoscutellum: absent. Posterior mesoscutellar sulcus: absent. Metascutellum: visible, partially covered by mesoscutellum. Metascutellar carina: present. Width of metasomal depression: greater than the length of lateral propodeal carina. Median carina between lateral propodeal carinae: absent. Transverse carina between lateral propodeal carinae: present. Foamy structure on transverse carina between lateral propodeal carinae: present. Foamy structure on metasomal depression: absent. Lateral propodeal carinae: parallel. Foamy structure on lateral propodeal carina: present only on the posterior half of the vertical part. Plica: visible. Posterior end of plica: free, converging with metapleural carina. Foamy structure on plica: present, fused with foamy structure from metapleural carinae. Foamy structure on metapleural carina: present on the entire carina. Foamy structure on ventral metapleural area: present. Setation of dorsal metapleural area: short setae on a longitudinal row. Setation of ventral metapleural area: dense, short hairs on posteroventral half. Longitudinal striation on dorsal mesopleuron: present. Transepisternal line: visible as a pit. Mesopleural carina: present. Metapleural sulcus: present. Wings. macropterous. Apex of fore wing: rounded. Colour of fore wing: infuscate. Transverse brown band on fore wing: absent. Submarginal vein in fore wing: present. Length of submarginal vein in fore wing: not surpassing basal 1/4 of fore wing. Spectral veins on fore wing: absent. Marginal setae of fore wing: present, well visible. Disc of fore wing: with spinulose microtrichia. Legs. Colour of fore tibia: light brown. Colour of fore tarsus: yellow. Colour of middle femora: light brown. Colour of middle tibiae: light brown. Colour of middle tarsus: yellow. Colour of hind femora: light brown. Colour of hind tibiae: yellow. Colour of hind tarsus: yellow.

Metasoma. Posterior of T2 some or all tergites may be retracted under T2. Shape of T1: trapezoidal. Colour of T1: brown. Lateral setae of T1: 3 pairs. Colour of T2: brown. Shape of T2: longer than wide. Anterior pits of T2: distinctly separated. Sculpture of T2, lateral to anterior pits of T2: absent. Colour of T3 -T5: the same as T2.

Distribution.

Czech Republic (Fig. 298 ).

Diagnosis.

Fidiobia bohemica is close to F. communis and F. hofferi because of the presence of notauli, the visible metascutellum and the reticulate-coriaceous to alutaceous sculpture of the frons. Fidiobia bohemica differs from these species by the presence of three pairs of sublateral setae on T1 (only two in F. communis and F. hofferi ) and the absence of epitorular carinae on the frons (present in F. communis and F. hofferi ).
