Description.

Female (Figs 1 View Figures 1–9 , 3 View Figures 1–9 , 5-6 View Figures 1–9 ): body length 8.0 mm, forewing length 8.5 mm. Black, with the following parts yellow: a basal band of clypeus (Fig. 3 View Figures 1–9 ), a large transverse interantennal spot, a small mark approaching the middle of inner orbits on the lower side of eye, postocular spot (Fig. 6 View Figures 1–9 ), a thin band on dorsal surface of pronotum (Fig. 1 View Figures 1–9 ), small spots on tegula anteriorly and posteriorly, elongated spots on dorsal faces of all tibiae, a broad apical band on each of T1-T4, and a thinner apical band on S2; tibiae except yellow spots and all tarsi dark brown. Wings slightly brownish.

Head. In front view, head much wider than long, its width 1.40 × length; clypeus (Fig. 3 View Figures 1–9 ) somewhat convex, with dense punctures, those on apex mostly so elongated as to forming thin and irregular longitudinal striations, clypeal width 1.60 × its length, total width: apical width = 4.0: 1.5, apex deeply emarginated, apical width: depth of emargination = 1.5: 0.7, interantennal space convex, without median carina; punctures on frons thick and reticulate; ocular sinus with sparser punctures; POD: OOD = 12: 21, diameter of anterior ocellus as long as the distance between anterior ocellus and posterior ocelli; vertex punctured, punctures somewhat weaker than those on frons; cephalic fovea obsolete; occipital carina strong only on sides.

Mesosoma. Anterior face of pronotum sparsely punctate, pronotal carina obsolete at middle, present and somewhat strong at its shoulder, and stopping abruptly below shoulder, the carina of lateral face well developed, somewhat arced, and not joining the carina of shoulder; punctures on mesosoma generally larger than those on head and metasoma; posterior face and lateral side of pronotum, mesoscutum, mesopleuron, and scutellum strongly punctured, punctures mostly so elongated as to forming irregular and reticulate striations; punctures on metanotum comparatively sparser; scutellum not convex; metanotum inclined; epicnemial carina of mesopleuron obsolete, present only on the lower side; dorsal surface of propodeum not convex, weakly punctured and with thin reticulate rugae, vertical median area somewhat concave, with thin, wavy, transverse rugae and a median carina, lateral side on the upper half with dense thin, long, and transverse rugae, on the lower half coriaceous and with indistinct rugae; posterior lobe of tegula rounded at the apex; apex of parategula reaching far beyond the apex of tegula (Fig. 5 View Figures 1–9 ).

Metasoma. In dorsal view, T1 domed, its width 1.89 × length and 0.80 × width of T2, T1 and T2 without apical lamellae; the narrow basal part of S1 coriaceous, posterior area of S1 with reticulate rugae and lateral carina; punctures on metasoma distinctly weaker than those on other portions of the body; punctures on T1 bigger than those of other terga; punctures on T2 at posterior area sparser; punctures on S2 bigger and sparser than those on T2; visible part of T3-T6 and S3-S6 coriaceous and with minute punctures; the apical yellow bands on T3 and T4 not extending to lateral margins, the band on T4 shorter than that of T3.

Male (Figs 2 View Figures 1–9 , 4 View Figures 1–9 , 7-9 View Figures 1–9 ). Body length 7.0 mm, forewing length 8.5 mm. Punctures, setae, and coloration similar to female except as follows: clypeus (Fig. 4 View Figures 1–9 ) entirely, most of mandible on the outside, labrum, ventral surface of antennal scape, all tibiae except ventral sides, dorsal sides of fore and mid tarsi I, ventral side of mid coxa (Fig. 8 View Figures 1–9 ), apex of mid femur ventrally, and apical bands on T1-T5 yellow; in front view, width of head 1.37 × its length; POD: OOD = 13: 22, diameter of anterior ocellus almost equal to the distance between anterior and posterior ocella; clypeus densely punctured, punctures on apex normal and not elongated, width of clypeus 1.38 × length, total width: apical width = 4.5: 1.4, apical emargination deeper than that in female, width: depth of emargination = 1.5: 0.9; antenna (Fig. 7 View Figures 1–9 ), apical segments coiled; the mark in eye incision (Fig. 4 View Figures 1–9 ), postocular spot and elongated spots on dorsal faces of all tibia larger than those in female; a small yellow spot on the left upper part of mesepisternum; tarsi except yellow parts ferruginous to brown; in dorsal view, width of T1 2.07 × its length and 0.81 × width of T2; apical bands on T2 and T3 pale and pellucid at the middle, the band on T5 shorter than those on T1-T4; the band on dorsal surface of pronotum wider than that in female; other characters same as those in female.

Recognition.

The species resembles Tropidodynerus fertoni (Dusmet, 1925) in scutellum and metanotum black, and propodeum without a sharp edge at the transition of dorsal surface to lateral side. It differs from Tropidodynerus fertoni and all other members of the genus by the following character combination: clypeal apex deeply emarginated in female, in male clypeal width: apical width = 4.5:1.4, apical width: depth of emargination =1.5:0.9, the band on dorsal surface of pronotum comparatively thinner; T1-T5 and S2 with apical yellow bands, respectively.

Distribution.

China (Ningxia).

Etymology.

The specific name liupanshanensis is the Neolatin adjective, with reference to the region from which the type specimens were collected.
