Material examined
2 ♀♀ (SCAU), Ningxia, Liupanshan Forest Park (35°22'54.76"N, 106°18'51.22"E), 3–4.VII.2009, Hua-yan Chen, No. SCAU-O0009, SCAU-O0010.
Diagnosis
Pronotum with scattered (1–2 PD), shallow punctures medially. Mesoscutum with notauli distinct, deep, complete. Mesopleuron with distinct striae between punctures. Metasoma pear-shaped, T-II notably wider than T-I. Apex of T-III with median notch V-shaped.
Description
Female (n = 2). Body length 4.1–4.6 mm (Plate 5). Fore wing length 3.3–4.0 mm. MS = 1.7 MOD. Head. Face with round, dense (0–0.5 PD), shallow punctures (Plate 6A). Scapal basin deep, smooth, glabrous, weakly striae laterally near antennal sockets (Plate 6A). Ocellar triangle isosceles. Postocellar line absent (Plate 6B). Gena with fine, transverse wrinkles. Mesosoma. Pronotum with scattered (1–2 PD), shallow punctures medially (Plate 6B); with small, deep pits on anterior margin; with large, dense (0–0.5 PD) punctures laterally (Plate 6B). Mesoscutum polished, with fine, scattered punctures between notauli; with dense, deep punctures between parapsidal lines and notauli (Plate 6D); notauli distinct, deep, complete; notaulic pit elongate; parapsidal lines shallower than notauli (Plate 6D). Scutellum without flattened fovea on anterior margin; with triangular and impunctate area antero-medially (Plate 6D); with shallow punctures laterally, and becoming larger and deeper towards alar foveae (Plate 6D). Mesopleuron with distinct striae between the punctures (Plate 6C). Metanotum evenly round, with large, deep, areolate punctures (Plate 6D). Propodeum with lateral margin slightly concave before propodeal angle; propodeal angle distinct, long, pointing posterolaterally. Tarsal claw with three teeth.
Metasoma. Oval, T-II notably wider than T-I, T-III distinctly constrict laterally towards the apex (Plate 6E), L/W = 9/5. T-I and T-II almost impunctate dorsally, with fine, scattered punctures laterally. T-III with finer, denser punctures than those on T-II (Plate 6E); apex of T-III with narrow (2/3 MOD) and brownish rim, with median notch V-shaped, 1/2 MOD deep (Plate 6F).
Colouration. Head and mesosoma mostly metallic bluish-purple, with face, mesopleuron and metapleuron metallic green. Antenna black, with scapes and pedicel metallic greenish-blue. Tegula metallic green, with apex brown. Leg metallic bluish-purple, with tarsus brown. Metasoma metallic blue with purple reflections, with T-II blackish dorsally.
Male. Unknown.
