Length of A3 of female: distinctly shorter than A2. Sensillar formula (A7:A8:A9): 2:2:1.

Mesosoma (Figs 88a , 91 ). Colour of mesosoma: dark brown. Mesosoma: cylindrical, not 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: not dilated. Lateral pronotal area: entirely sculptured. Antero-admedian line: absent. Mesoscutum: convex. Parapsidal lines: absent. Sculpture of internotaular area: smooth, almost absent in posterior half, imbricate coriaceous anteriorly. Notauli: present as a change in sculpture or pilosity. Shape of notauli: dilated posteriorly and rounded anteriorly. Outer edge of notauli: almost collinear with axillular carina. Orientation of inner edge of notauli: 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: at most 1.9 times as long as maximum width. Distance between notauli: shorter than the broadest part of notaulus. Transscutal articulation: complete. Scuto-scutellar sulcus: present only laterally. Fovea on scuto-scutellar sulcus: present on the entire length of scutelo-scutellar sulcus. Mesoscutellum: convex. Shape of mesoscutellum: semicircular. Axillular carina: posterior apex of axillular carinae not abutting posterior edge of mesoscutellum. Axilloaxillular carina: absent. Sculpture of mesoscutellum: absent. Posterior mesoscutellar sulcus: present. Metascutellum: entirely visible. 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: absent. Foamy structure on transverse carina between lateral propodeal carinae: NA. Foamy structure on metasomal depression: absent. Lateral propodeal carinae: divergent posteriorly. Foamy structure on lateral propodeal carina: absent. Plica: not visible. Posterior end of plica: NA. Foamy structure on plica: NA. Foamy structure on metapleural carina: present on the entire carina. Foamy structure on ventral metapleural area: absent. Setation of dorsal metapleural area: short setae on entire surface, uniformly distributed. Setation of ventral metapleural area: short setae uniformly distributed on the entire surface. Longitudinal striation on dorsal mesopleuron: present. Transepisternal line: visible as a pit. Mesopleural carina: absent. Metapleural sulcus: present, complete. Wings (Fig. 89 ): 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 the length 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: brown, with lighter basal and apical ends. Colour of fore tarsus: light brown with darker pretarsus. Colour of middle femora: brown with lighter basal and apical ends. Colour of middle tibiae: brown with lighter basal and apical ends. Colour of middle tarsus: light brown with darker pretarsus. Colour of hind femora: brown with lighter basal and apical ends. Colour of hind tibiae: brown with lighter basal and apical ends. Colour of hind tarsus: light brown with darker pretarsus.

Metasoma (Fig. 88a ): 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.

Male. unknown.

Etymology.

Distribution.

This species was encountered only in Far East Russia and South Korea (Fig. 305 ).

Biology.

unknown.

Diagnosis.

Fidiobia hirta differs from other species in the genus because the body is not flattened dorsoventrally, the mesoscutum and mesoscutellum are convex in lateral view, the metasomal depression is large, the lateral propodeal carinae diverge posteriorly, and T3 is at least as long as its maximum width.
