( Figs 12–21 View FIGURES 12–21 )

Diagnosis. This species can be recognized by the following combination of characters: propodeal areola ( Fig. 16 View FIGURES 12–21 ) subtrapezoidal and medial longitudinal carina reaching posterior 3/5 of areola, subposterior groove on T1 ( Fig. 17 View FIGURES 12–21 ) without a row of minute punctures, and S1 ( Fig. 19 View FIGURES 12–21 ) smooth, only with few scattered and shallow punctures.

Black, with mandible, flagellum, tegula, legs and pterostigma dark brown ( Figs 12, 13 View FIGURES 12–21 ); wing venation brown. T3–T5 with dense, erect, short brown setae intermixed with erect long whitish ones ( Fig. 18 View FIGURES 12–21 ).

Head. Mandible without distinct medial transverse groove, at most with obsolete intermittent impressed line; W: OW: L: IOD=32: 17: 14: 22; OOD: POD: Od=15: 15: 5.5; AOD: WAS: IAD: CL: CAW=10: 9: 5.5: 12: 7; punctures of clypeus ( Fig. 13 View FIGURES 12–21 ) basally sparse and laterally denser, ventral margin medially convex and slightly emarginated in middle, lateral margin convex, without thickened; frons ( Fig. 13 View FIGURES 12–21 ) with a medial narrow carina; upper frons with sparse punctures; lower frons with smaller and denser punctures; vertex ( Fig. 14 View FIGURES 12–21 ) with smaller and sparser punctures than those on frons.

Mesosoma. Pronotal dorsal face with sparse punctures, sparser medially ( Fig. 15 View FIGURES 12–21 ); pronotal lateral face ventrally with dense oblique striae; mesoscutum with notaulus, medially with dense punctures, sparser laterally; mesopleuron with moderate punctures, almost evenly spaced; metanotal trough and metascutellum with sparse and small punctures ( Fig. 16 View FIGURES 12–21 ); propodeal dorsal face with lateral carina, well developed and posteriorly with short striae connecting transverse carina; propodeal areola ( Fig. 16 View FIGURES 12–21 ) subtrapezoidal, slightly convergent posteriorly, APWL=1.89: 0.89: 2.56, medial longitudinal carina reaching posterior 3/5 of areola; surface of propodeal areola medially flat; 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. 12 View FIGURES 12–21 ) with pterostigma, and apex of marginal cell not exceeding the second submarginal cell.

Metasoma. T1 ( Fig. 17 View FIGURES 12–21 ) with sparse and big punctures, subposterior groove without a row of minute punctures; S1 ( Fig. 19 View FIGURES 12–21 ) anteriorly with medial longitudinal carina, and only with few scattered and minute punctures; surface of S1 gradually inclined posteriorly and smooth, without posterolateral groove; T2 ( Fig. 17 View FIGURES 12–21 ) anteriorly without transverse row of short longitudinal striae; T3–T5 ( Fig. 18 View FIGURES 12–21 ) with dense, erect, short brown setae intermixed with erect long whitish ones and dense punctures; T1–T6 posteriorly with thin lamellae; posterior margin of S2–S5 ( Fig. 19 View FIGURES 12–21 ) with sparse recumbent long whitish setae; S5 ( Fig. 20 View FIGURES 12–21 ) with lateral denticle, nearly longitudinal and slightly curved inwards, without distinct hollow; T6 with sparse punctures, and without dense, erect, short brown setae; T7 ( Fig. 21 View FIGURES 12–21 ) with one medial longitudinal impunctate area.

Female. Unknown.

Distribution. China ( Sichuan).

Remarks. This new species is similar to T. ( J.) ami Tsuneki, 1986a from Taiwan, China by having the following character states: frons ( Fig. 13 View FIGURES 12–21 ) with a medial narrow carina; T3–T5 ( Fig. 18 View FIGURES 12–21 ) with dense, erect, short brown setae intermixed with erect long whitish ones and dense punctures, and posterior margin of S2–S5 ( Fig. 19 View FIGURES 12–21 ) without dense, erect, short, brown setae. However, this new species differs from it by having the subposterior groove on T1 ( Fig. 17 View FIGURES 12–21 ) without a row of minute punctures; S1 ( Fig. 19 View FIGURES 12–21 ) smooth, with few scattered and shallow punctures.

Etymology. The specific name displicata is derived from a Latin adjective displicatus (= spread), referring to the few scattered punctures on S1.
