Abstract:This paper gaves descriptions of a new subgenus and semen species of the Triozidae from China. The types deposited in the Insect Collections of Beijing Agricultural University.Gen. Hippophaetrioza, star. N. (figs. 1, 2)Body medium size, stout, with short pubescence, genal cones strongly divergent, clypeus visible from between genal cones. Antenna moderately long, longer than the width of head. Pronotum on same plane with vertex and praescutum. Metatibia with rugosity at base and three or four spins at apex. Forewing transparent or maculated, always round at apex, without evendtly pterostigma or with pseudopterostigma. M and Cula with short common petiole. Hind wing broad and large, R, M and Cul arising from the same point or M and Cu1 with common petiole.Male genital segment complex with proctiger almost cylindic, parameres inside with convex at base, aedagus first segment stout at base and slender at apex.Female genital segment very particular, dorsal valve with very sclerotic as falciform distal parts and expanded circumanal parts, proctiger between anus and apex very convex, like a hemisphere. Ventral valve very short and shape variety.Type species: Trioza binotata Low, 1883.Distribution: Austria, Switzerland, Italy, Russia China.Host plant: Hippophae spp.Subgen. Maculatrioza, subgen, n. (figs. 2, 3, 4)Type species: Hippophaetrioza(Maculatrioza) Maculata sp. N.New subgenus differs from the subgenus Hippophaetrioza as follows: body more stout; forewing near rhombus, veins and membrance with irrgula maculata; hind wing R, M and Cula arising from same point and three tiabl spurs at apex. Female genital segment also differs from the latter in having expanded circumanal parts longer than scleroted distal parts and ventral valve nearly rectangle.The new combined list of species of Hippophaetrioza Subgenus 1 Hippophaetrioza Conci et Tamanini 1984.H.

(fig.3)Holotype , allotype , paratyp 2 , Xizang Aut. Reg. Nyinchi Co. Gengzhang(3050m) 1978-Ⅵ-1.Host plant: Hippophae rhamnoides(L.)New species related to the Hippophaetrioza (M.) xizangana (Li et Yang), but differs from the latter in having both body andforewing markings brown colour(xizangana is blacked).2.Hippophaetrioza(Maculatrioza)formosa,sp. N. (figs. 2, 4)Holotype ♀, paratype 1♀, Xizang Aut. Reg. Xigaze Co. (3900m) 1978-Ⅷ-28.Host plant: Hippophae rhamnoides(L. )New species is similer to the Hippophaetrioza (M.) rnaculata,sp, n., but differs from the latter in having forewing marking little and dorsal and inner valve of female genitalia very different.3. Hippophaetrioza (Hippophaetrioza)chinensis, sp. N. (fig. 5)Holotype , allotype ♀, paratypes 120, 210♀♀, Shanxi Prov. Wenshui Co. Guandishan(1700—2000m), 1987-Ⅵ-16; 10, 9♀♀, same as holotype 1987-Ⅵ-17; 2♀♀, Ningxia Hui Aut. Reg. Longd Co. Liupanshan(2300m)1980-Ⅶ-14; 1♀, Shannxi Prov. Ganquan Co. Qingquangao 1972-Ⅲ Host plant: Hippophae rhamnoides(L.)New species is similar to Hippophaetrioza (H.) tienshanica (Loginova) from Russian in the forewing markings, but easily distinguished in the anus longer, about 1/2 length as base part or dorsal valve, inner valve also different.4. Hippophaetrioza (Hippophaetrioza) guangwui, sp. N. (fig. 6)Holotype , allotype ♀, paratypes 8, 9♀♀, Shanxi Prov. Wenshui Co. Guadishan (1700—2000m) 1987-Ⅵ-16.Host plant: Hippophae rhamnoides(L.)New species and anterior species found in the same host and locality, but differs from above new species by the body longer(to the tipe of holded wings) 3.42, ♀ 3.75mm; forewings without markings to be except of margin marking.5. Hippophaetrioza (Hippophaetrioza) nyingchensis, sp. n. (fig. 7) Holotype , allotype ♀, paratype 1, Xizang Aut. Reg. Nyingchi Co. Gengzhang(3050m) 1978-Ⅵ-1.Host plant: Hippophae rhamnoides(L.)New species is similar to the Hippophaetrioza(H.) binotata(Low)which described from Austria, Switzerland and Italy on Hippophae rhamnoides, but differs from latter in having M forked shorter and also inner valve of female genitalia distinctly different.6. Hippophaetrioza(Hippophaetrioza) incurva, sp. N. (figs. 2, 8)Holotype , allotype ♀, Xizang Aut. Reg. Nyingchi Co. Gengzhang(3050m)1978-Ⅵ-1; paratypes 1♀, Lhasa C. (3700m) 1978-Ⅷ-16, 1♀, Nedong Co. (3500m) 1978-Ⅷ-9.Host plant: Hippophae rhamnoides (L.), H. thibetana Schlechtand.New species resembles the anterior species in the shape and marking of forewing, but differs from former in having Rs-M1+2 about equal M1+2-M3+4, Cula broader and also dorsal and inner valve of female genitalia very different.7. Hippophaetrioza(Hippophaetrioza)qinghiensis, sp. N. (fig. 9)Holotype , Qinghai Prov. Datong Co. 1965-Ⅴ-11.New species differs from species of Hippophaetrioza in character parameres of cone-shaped and slightly curved of male genitalia lateral aspect. Differs from H. (H.)guangwui, sp. N. in having vertex and genal cones short and broad, male 9th sternum longer and paramers hind margin convex in lateral aspect.
