Fredegunda sinica Liu, He & Chen sp. nov.

( Figs. 1–8 )

Holotype. Female. Body length 10.8 mm, fore wing length 6.4 mm, ovipositor sheath length 3.1 mm, antenna 4.4 mm.

Head. Mandible stout, with upper teeth as long as the lower one. Malar space short and finely granulate, 0.4 times as long as the basal width of mandible. Clypeus bilobed, flatten, with basal 0.2 weakly convex. Lower face centrally convex and laterally depressed, smooth with sparse punctures. Frons finely pubescent. Head in dorsal view transverse, 1.8 times as wide as long. Temple subparallel behind eyes, 0.7 times as long as eye in dorsal view. POL: OOL: OD=15: 18: 13. Vertex smooth and sparsely pubescent. Antenna with 23 antennomeres, first flagellomere 5.2 time as long as wide, and second flagellomere 3.8 times as long as wide.

Mesosoma. Pronotum smooth with dorsal margin finely punctate and hairy. Epomia present but weak. Mesoscutum weakly and evenly convex, finely punctate and pubescent. Notaulus shallow, present on anterior 0.3. Scutellum roundly convex, sparsely punctate. Median longitudinal carinae of propodeum strong, reaching to apical 0.7 and diverged outward, area between median longitudinal carinae smooth and bare; lateral area of propodeum coarsely punctate with basal 0.2 smooth, pleural area punctate, lateral carina present on apical 0.3, pleural carina complete. Spiracle round and closed to pleural carina. Mesopleuron sparsely punctate and hairy on anterior 0.7 and lower side, prepectal carina strong and reaching to upper 0.6 with upper end separated from the anterior margin of mesopleuron, speculum smooth and bare. Metapleuron punctate on dorsal 0.6 and smooth on lower 0.4, submetapleural carina complete and strong.

Wings. Fore wing with cu-a opposite base of Rs &M, areolet present and receiving 2m-cu at apical 0.2. Hind wing with 1Cu1: cu-a=3: 2, distal abscissa of Cu1 present.

Legs. Hind femur 3.8 times as long as wide, relative ratio of length of 1–5 hind tarsomeres as follows: 10: 4: 2: 1: 4.

Metasoma. T1 punctate, 0.85 times as long as apical wide in dorsal view, basal declivity smooth, median dorsal carina reaching to apical 0.7, dorsolateral carina complete. T2 0.7 times as long as its apical width, densely and coarsely punctate except for apical transverse smooth band and two smooth patches behind gastrocoele. T3–T5 transverse, densely and coarsely punctate, tubercles weakly indicated. T6 with dense and fine punctures. T7 with fine semicircular punctures and hairy. Ovipositor sheath hairy, 1.8 times the length of hind tibia.

Colour. Body black. Antenna brown. Mandible black, with apical 0.3 reddish brown. Palpi yellowish brown. Dorsal margin of pronotum with posterior 0.3 yellow. Tegula yellow. Scutellum reddish brown. Metasoma blackish brown with apical transverse smooth band black. Fore and middle legs yellowish brown, hind leg reddish brown with apical 0.2 of coxa, trochanter, anterior side of tibia yellowish brown, tarsus yellowish brown with apical 0.2 of 1–5 tarsomeres black. Wings hyaline, veins dark brown and stigma black.

Variations. Paratype body length 6.1 mm, fore wing length 5.0 mm, colour of metasomal tergites lighter. Punctures on lateral areas of propodeum are more sparse.

Male. Unknown.

Host. Unknown.

Distribution. China (Fujian).

Materials examined. Holotype, female, CHINA: Fujian province, Chong An, Huanggangshan (27.88°N, 117.75°E), 1985. VII.30, Geng Zheng, No. 201008318. Paratype. 1 female, same locality as type, 1985. VII.30, Xin- Jin Chen, No. 20108279.

Diagnosis. This species is very similar to Fredegunda diluta (Ratzeburg, 1852) which is widely distributed in Western Palearctic region, but differs from the latter by: 1) face, frons and vertex smooth, sparsely hairy (the latter with dense punctures); 2) ovipositor sheath 1.8 times length of hind tibia (the latter 1.5–1.6 times); 3) body mainly black, with metasoma blackish brown (the latter with mesosoma and metasoma reddish).

Etymology. The name refers to the type locality, China.
