Glaresis orientalis Medvedev, 1976  ( Figs. 11–20View FIGURES 11 – 20)

Glaresis orientalis Medvedev, 1976: 155  , figs. 1–2.

Type locality. “Mongoliya, Sukhe-Batorskiy aimak [= nowadays Ömnögovi Province], peski [= dunes] Ongon Els, 15 km YUYUV Khongora [= SSE of Khongor] [original in Cyrillic]”.

Type material examined. Mongolia, Ömnögovi Province: Holotype: ♀ ( ZMAS), “ Mongoliya, Sukhe-Batorskiy aimak | peski Ongon-Els | 15 km YUYUV Khongora || 5-6 VII 1971 (I. M. Kerzhner) [original in Cyrillic, printed]”. 

Additional material examined. China, Nei Menggu: Alxa Left Banner , 11.vii.2011, Hu Zhiyong lgt., 1 ♀ ( NMPC), 1 ♀ ( IZAS)  . Mongolia, Bayankhongor Province: 8 km S von somon Zinst , 1400 m, 25.vi.1964, Exp. Dr. Z. Kaszab, 3 ♂♂ 1 ♀ ( NMPC), 12 specimens ( HNHM)  .

Diagnostic characters. Robust, strongly convex, weakly widened posteriad; brownish yellow in colour, slightly shiny; macrosetation pale ( Figs. 11–12View FIGURES 11 – 20). Anterior margin of clypeus shallowly sinuate, distinctly upturned; lateral angles rounded; lateral margin bisinuate; posterior angles acute-angular ( Fig. 14View FIGURES 11 – 20). Surface of frons and clypeus covered with sparsely, irregularly spaced, shiny tubercles ( Figs. 12, 14View FIGURES 11 – 20). Pronotum with shallow medial longitudinal and anterior transverse grooves weakly impressed, lateral impressions strong, grooves beside longitudinal groove absent; posterior angles protruding in short tips ( Figs. 11–12View FIGURES 11 – 20); surface covered with densely almost regular longitudinal carinae, each carina bearing thick, recumbent macroseta. Meso-metaventral plate flat, smooth; surrounded by a row of stout macrosetae; with darkened, transclucent, longitudinal endocarina medially ( Fig. 15View FIGURES 11 – 20). Mesotibial fossae of mesometaventrum present, distinctly impressed, with sharp edges, divergent posteriad ( Fig. 15View FIGURES 11 – 20). Posterior-superior margin of metafemora with weak protuberance ( Figs. 19–20View FIGURES 11 – 20). Protibia tridentate ( Figs. 11–12View FIGURES 11 – 20). Mesotibia long, nearly straight; distal part of outer edge of mesotibiae straight, bearing 7–9 short, stout spines; basal external tooth of mesotibia straight basally ( Figs. 17–18View FIGURES 11 – 20). Metatibia broadly triangular, outer margin irregularly serrate with a median projection, strongly macrosetaceous ( Fig. 20View FIGURES 11 – 20); row of 4 spine-bearing tubercles extending from base to apex medially ( Fig. 19View FIGURES 11 – 20); inner margin smooth, macrosetaceous; apex of metatibia with outer horseshoe-shaped portion subequal to inner spur-bearing portion; inner margin of the horseshoe shape with a row of contiguous short macrosetae ( Figs. 19–20View FIGURES 11 – 20). Aedeagus ( Fig. 13View FIGURES 11 – 20) with parameres distinctly longer than phallobasis; parameres only weakly sclerotized, lateral margin nearly straight, almost truncate apically; tips acute; phallus sclerotized, sides straight, weakly convergent anteriad. Female differs from male in being indistinctly broader posteriad. Total body length: 4.3–4.5 mm.

Distribution. Central Asia: China (Inner Mongolia) and Mongolia (Bayankhongor, Ömnögovi).

Remarks. Glaresis orientalis  was described by Medvedev (1976) based on a single female. Later, Nikolajev & Puntsagdulam (1984) synonymized this species with G. oxiana  . Nikolajev & Puntsagdulam’s (1984) synonymy was subsequently rejected by Nikolajev (2006), who did so in a catalogue without providing any justification for the resurrection. Examination of the holotype showed some important characters for differentiating G. orientalis  from G. oxiana ( Zídek 2015)  . Study of considerably more material of both males and females from southern Mongolia and Inner Mongolia (China) by us has confirmed that Glaresis orientalis  is a valid species. For a clearer differentiation see identification key below.
