( Figs 1–11 View FIGURES 1–11 )

Diagnosis. This species can be recognized by the following combination of characters: propodeal areola ( Fig. 7 View FIGURES 1–11 ) subrectangular and weakly convergent posteriorly, its surface strongly arched medially and gradually inclined posteriorly; T1 ( Figs 1, 9 View FIGURES 1–11 ) with sparse punctures except medial part with a few denser and bigger punctures; S1 ( Fig. 10 View FIGURES 1–11 ) without a lateral groove; T3–T5 ( Fig. 9 View FIGURES 1–11 ) with erect long whitish setae only.

Description. Female ( Fig. 1 View FIGURES 1–11 ). Body length 8.7 mm. Forewing length 5.9 mm. Black with erect long whitish setae, with mandible, anterior margin of clypeus, femora and tibiae reddish brown ( Figs 1–2 View FIGURES 1–11 ); wing venation light brown; flagellum, coxae, metatrochanter, tarsi, tegula, pterostigma and posterior portion of pygidium dark brown ( Figs 4, 8, 11 View FIGURES 1–11 ).

Head. Mandible without distinct medial transverse groove, at most with obsolete intermittent impressed line; W: OW: L: IOD=38: 19: 21: 25; OOD: POD: Od=20: 13: 5; AOD: WAS: IAD: CL: CAW=22: 8: 6: 9: 9; clypeus ( Fig. 2 View FIGURES 1–11 ) with dense and small punctures, ventral margin medially convex and slightly emarginated in middle, lateral margin not convex nor thickened; frons ( Fig. 2 View FIGURES 1–11 ) with one medial longitudinal narrow groove; upper frons with sparse punctures; lower frons with denser punctures; vertex ( Fig. 3 View FIGURES 1–11 ) with dense and large punctures on lateral side of ocellus, postocellar area with sparse punctures, upper anterior-ocellus punctures relatively smaller and sparser than those on postocellar area, with interspaces smooth.

Mesosoma. Pronotal dorsal face with dense and coarse punctures, almost evenly spaced ( Fig. 5 View FIGURES 1–11 ); pronotal lateral face ventrally with dense oblique striae ( Fig. 6 View FIGURES 1–11 ); mesoscutum with sparse punctures, punctures gradually denser from anterior to posterior portion; notaulus connecting anterior medial groove; mesopleuron with dense punctures, somewhat reticulate; metascutellum with big and deep punctures; propodeal dorsal face ( Fig. 7 View FIGURES 1–11 ) without lateral carina and posteriorly with short striae connecting transverse carina; propodeal areola ( Fig. 7 View FIGURES 1–11 ) subrectangular, weakly convergent posteriorly, APWL=1.84: 0.99: 3.67, medial longitudinal carina reaching posterior 4/5 of areola, surface of propodeal areola strongly arched medially, gradually inclined posteriorly; propodeal lateral face anteriorly with long dense oblique wrinkles, posteriorly with dense and minute punctures and short medial longitudinal carina on ventral 1/4; tegula smooth, sparsely punctate, posterior margin without transverse impressed line; forewing ( Fig. 8 View FIGURES 1–11 ) with pterostigma, and apex of marginal cell open.

Metasoma. T1 ( Figs 1, 9 View FIGURES 1–11 ) with sparse punctures except medial part with a few denser and bigger punctures, subposterior groove without a row of minute punctures; S1 ( Fig. 10 View FIGURES 1–11 ) anteriorly puncto-reticulate and with shallow medial longitudinal groove, without posterolateral groove and medial carina, and medially with scattered and minute punctures; T2 ( Fig. 1 View FIGURES 1–11 ) anteriorly with transverse row of short longitudinal striae; T1–T5 posteriorly with thin lamellae; T3–T5 ( Figs 1, 9 View FIGURES 1–11 ) medially with dense punctures, sparser laterally; pygidium ( Fig. 11 View FIGURES 1–11 ) medially with large punctures and longitudinal carinae, with few strong subposterior setae, and posteriorly smooth.

Male. Unknown.

Distribution. China ( Inner Mongolia).

Remarks. This new species is similar to T. ( J.) punctata Smith, 1873 from Japan by having the following character states: clypeus ( Fig. 2 View FIGURES 1–11 ) with dense and small punctures, ventral margin medially convex and slightly emarginated in middle, lateral margin not convex nor thickened; T2–T5 ( Fig. 9 View FIGURES 1–11 ) with erect long whitish setae. However, this new species differs from it by having S1 ( Fig. 10 View FIGURES 1–11 ) without a lateral groove (with a lateral groove on posterior half in T. punctata Smith, 1873 ).

Etymology. The specific name hohehotensis is derived from the type locality, Hohehot, China.
