(Figs 12–21)
Diagnosis. This species can be recognized by the following combination of characters: propodeal areola (Fig. 16) subtrapezoidal and medial longitudinal carina reaching posterior 3/5 of areola, subposterior groove on T1 (Fig. 17) without a row of minute punctures, and S1 (Fig. 19) smooth, only with few scattered and shallow punctures.
Material examined. Holotype, ♂, China, Sichuan prov., Liangshan County, Dechang Town, Jinchuan Village, 27°11′20″N, 102°17′5″E, 1201m, 31.VII.2011, Zhenhu Wu (CNU).
Description. Male (Fig. 12). Body length 6.66 mm. Forewing length 4.4 mm. Black, with mandible, flagellum, tegula, legs and pterostigma dark brown (Figs 12, 13); wing venation brown. T3–T5 with dense, erect, short brown setae intermixed with erect long whitish ones (Fig. 18).
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) basally sparse and laterally denser, ventral margin medially convex and slightly emarginated in middle, lateral margin convex, without thickened; frons (Fig. 13) with a medial narrow carina; upper frons with sparse punctures; lower frons with smaller and denser punctures; vertex (Fig. 14) with smaller and sparser punctures than those on frons.
Mesosoma. Pronotal dorsal face with sparse punctures, sparser medially (Fig. 15); 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); propodeal dorsal face with lateral carina, well developed and posteriorly with short striae connecting transverse carina; propodeal areola (Fig. 16) 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) with pterostigma, and apex of marginal cell not exceeding the second submarginal cell.
Metasoma. T1 (Fig. 17) with sparse and big punctures, subposterior groove without a row of minute punctures; S1 (Fig. 19) 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) anteriorly without transverse row of short longitudinal striae; T3–T5 (Fig. 18) 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) with sparse recumbent long whitish setae; S5 (Fig. 20) 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) 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) with a medial narrow carina; T3–T5 (Fig. 18) with dense, erect, short brown setae intermixed with erect long whitish ones and dense punctures, and posterior margin of S2–S5 (Fig. 19) without dense, erect, short, brown setae. However, this new species differs from it by having the subposterior groove on T1 (Fig. 17) without a row of minute punctures; S1 (Fig. 19) 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.
