Genus Mongoliana Distant, 1909

Mongoliana Distant, 1909: 87 .

Type species. Hemisphaerius chilocorides Walker, 1851 , by original designation.

Diagnostic characters. Hemispherical, brown to testaceous issids. Head including eyes wider than pronotum. Vertex quadrilateral, anterior margin transverse, median carina distinct, posterior margin shallowly concave, all margins ridged, disc shallowly depressed. Frons slightly longer than wide, a little widened below antennae, with or without a linear series of small tubercles along lateral margins. Frontoclypeal suture straight or arcuate. Ocelli absent. Clypeus small, triangulate, with two round small depressions near frontoclypeal suture. Pronotum with small tubercles along anterior and posterior margins, disc slightly excavate, medially with a pair of pits; median carina faint. Carinae of mesonotum sometimes weak, with two round depressions, baso-lateral angles with tubercules. Tegmina coriaceous, convex, widened at basal costal margin, veins inconspicuous, claval suture absent. Hind wings 0.7–0.8 times length of tegmina, distinctly reticulate in distal half, ScP+R usually furcate in apical half, MP and CuA usually furcate submedially and highly branched distad, CuP and Pcu simple. Metatibiotarsal formula 2+(6-7)/(7-9)/2.

Male terminalia. Anal tube with apical margin convex, concave or nearly straight in middle. Pygofer relatively wide in lateral view, posterior margin convex near middle. Aedeagus shallowly U-shaped in lateral view, with pair of ventral processes; dorsolateral lobe of phallobase split into dorsal and lateral lobes from middle to apical 1/4, dorsal margin of lateral lobe smooth or serrate near apex. Genital styles triangular or rectangular in profile, narrowed at base and broadened apicad, hind margin weakly or distinctly concave, caudo-ventral angle widely rounded.

Female terminalia. Anal tube almost ovate. Gonoplacs wide and short in lateral view. Proximal part of posterior connective lamina of gonapophyses IX convex. Anterior connective lamina of gonapophysis VIII with three small teeth in apical group. Gonocoxae VIII nearly rectangular, hind margin concave.

Distribution. China, Japan.
