Han, Qian, Chen, Bin & Li, Ting-Jing, 2021, Three new species of the subgenus Jaynesia Allen, 1969 of the genus Tiphia Fabricius, 1775 (Hymenoptera: Tiphiidae: Tiphiinae) from China, with a key to all known species, Zootaxa 4970 (2), pp. 313-324 : 316-318

Tiphia (Jaynesia) hohehotensis Han, Chen & Li , sp. nov.

( Figs 1–11 )

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

Material examined. Holotype, ♀, China, Inner Mongolia, Hohehot City , 40°28′48″N, 111°24′36″E, 1040 m, 19.VII.2016, Zhenxia Ma ( CNU).

Description. Female ( Fig. 1 ). 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 ); wing venation light brown; flagellum, coxae, metatrochanter, tarsi, tegula, pterostigma and posterior portion of pygidium dark brown ( Figs 4, 8, 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 ) with dense and small punctures, ventral margin medially convex and slightly emarginated in middle, lateral margin not convex nor thickened; frons ( Fig. 2 ) with one medial longitudinal narrow groove; upper frons with sparse punctures; lower frons with denser punctures; vertex ( Fig. 3 ) 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 ); pronotal lateral face ventrally with dense oblique striae ( Fig. 6 ); 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 ) without lateral carina and posteriorly with short striae connecting transverse carina; propodeal areola ( Fig. 7 ) 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 ) with pterostigma, and apex of marginal cell open.

Metasoma. T1 ( Figs 1, 9 ) with sparse punctures except medial part with a few denser and bigger punctures, subposterior groove without a row of minute punctures; S1 ( Fig. 10 ) 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 ) anteriorly with transverse row of short longitudinal striae; T1–T5 posteriorly with thin lamellae; T3–T5 ( Figs 1, 9 ) medially with dense punctures, sparser laterally; pygidium ( Fig. 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 ) with dense and small punctures, ventral margin medially convex and slightly emarginated in middle, lateral margin not convex nor thickened; T2–T5 ( Fig. 9 ) with erect long whitish setae. However, this new species differs from it by having S1 ( Fig. 10 ) 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.
