Material. Holotype female NIGP156997 View Materials . Deposited at the Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences.

Etymology. The specific epithet refers to the city of Fushun near where the amber is collected.

Diagnosis. The species is characteristic in having cylindrical palpal segments 3 and 4 and wing veins M 1 and M 2 strongly divergent. Males unknown.

Description. Female. Dark brown in colour, partially distorted, wing venation only poorly visible. Total body length (including head): 1.2 mm.

Head. Flagellum length 0.37 mm. AR 0.95. Antenna with 13 cylindrical flagellomeres, distal 5 flagellomeres distinctly elongate, last flagellomere longest ( Figure 4.1 View FIGURE 4 ). Flagellomere 12 appears enlarged but this most probably an artefact. Palpus ( Figure 4.3 View FIGURE 4 ) short, with five segments, only terminal three palpal segments clearly visible, about 0.072 mm in length, palpal segments 3 and 4 cylindrical, palpal segment 3 with distinct sensory pit.

Thorax. Legs slender, unarmed. Hind basitarsus with row of palisade setae. Tarsomeres 2–4 short, tarsomere 4 cordiform, tarsomere 5 longer than preceding ones but shorter than combined length of tarsomeres 2–4. Tibial comb composed of six spines. Claws ( Figure 4.4-6 View FIGURE 4 View FIGURE 5 View FIGURE 6 ) single on all legs, claw of foreleg as long as tarsomere 5, claws of mid- and hind leg shorter. TR(I) 2.86, TR(II) 3.50, TR(III) 3.57. Wing length: 0.65 mm, CR 0.47. Ratio of divergence between M 1 and M 2: 0.29. Veins poorly visible, M 1 and M 2 ( Figure 4.2 View FIGURE 4 ) strongly divergent, M 1 meeting wing margin at right angle. Membrane without macrotrichia, microtrichia present.
