【摘要】 <正> 根据珠穆朗玛峰及其附近地区生物考察的瓢虫科材料,属于食植瓢虫亚科的有19种,其中6个新种,7种为我国分布的新记录。 全部瓢虫科材料主要采集于西藏自治区的聂拉木、亚东、错那、察隅、泽当、墨脱和波密等地区,最高海拔达5,200米。在4,000米以上地点采获的主要属于瓢虫亚科的瓢虫族(Coccinellini),食菌瓢虫族(Psylloborini)和长足瓢虫族(Hippodamiini)。食植瓢虫亚科的材料则在海拔3,000米以下,这与其食料植物的垂直分布有关。更多还原

【Abstract】 The present paper deals with 19 species of Epilachniuae,belonging to 4 genera,Epilachna,Henosepilachna,Afidentula and Afissula,collected from Tibet Autonomous Region,among which 7 species are new records of China and 6 species are new to science.Types are preserved in the Peking Institute of Zoology,Academia Sinica.Epilachna nielamuensis sp.nov.Upper side yellowish brown.Each elytron with 5 black spots (fig.1-4).It is related to Epilachna complicata (Dieke),but may be recognized by the shape of pronotal spot,and can easily be distinguished from other species with 5 elytral spots of the male genitalia (fig.1).Holotype:Male (No.G007),Xizang (Nielamu),2,000-2,500 m,1966.V.9 (Wang Shu-yong).Epilachna.chayuensis sp.nov.Upper side yellowish brown.Each elytron with 6 black spots as in figs.2-3.Femeral-lines subcomplete,reaching about 1/2 of sternite,extending to the anterior corner of abdomen.Male genitalia resemble those of Epilachna ocellatae-maculata (Mader),but paramera about 3/4 median lobe in length (fig.2). Holotype:Male (No.74131),Xizang (Chayu) 2,070-2,100m,1973.Ⅷ.1 (Huang Fu-sheng).Allotype:Female (No.753206),Xizaag (Chayu),2,070-2,100m,1973.Ⅷ.2 (Huang Fu-sheng).Paratype; 1 male,2 females,same as the holotype.Epilachna circummaculata sp.nov.Upper side brick red with black pattern as in fig.3.Prontum with outer margin rather straight,slightly narrower anteriorly,anterior margin emarginate.Femoral lines incomplete,extending posterior near the hind margin,then strongly recurved basally,reaching to 1/2 of the sternite.Genital plates of female broadly oval,with the bent over apical part of stergite X.Holotype:Female (No.753202),Xizang (Bomi),2,900m,1973.Ⅷ.6 (Huang Fu-sheng).Epilachna cuonaensis sp.nov.Upperside brown red with 5 black elytral spots (fig.4),somewhat resembles to Epilachna chincnsis (Weise).The noticeable difference is that the median lobe of male genitalia hightly developed,sides parallel,basal 1/2 comparatively thick,apical 1/2 very thin,on upper and lowerside with a knifesharp edge (fig.4).Holotype:Male (No.753204),Xizang (Couna),2,900m,1973.Ⅷ.6 (Huang Fu-sheng).Epilachna tridecimmaculosa sp.nov.Upperside yellowish brown,with black spots as in fig.5.Median part of pronotum with 2 indistinct foveoles (fig.5).Femoral lines semicircular,complete,extending to 3/4 of sternite,reaching anterior margin.Tarsal claw divided,inner claw much wider than outer,and apical in contact.Median lobe of male genitalia decressing in thickness gradually from base to apex,which is bent up near the middle and sharply into a sharp point (fig.5).Holotype:Male (No.G011),Xizang (Nielamu),1,680-2,250 m.1966.Ⅴ.9 (Wang Shu-yong).Henosepilachna quadriplagiata sp.nov.Upperside brownish red.Head with black eyes and tip of mandibles,lateral side yellowish brown.Scutellum,elytral suture,basal and outer margin of elytra black,with a transverse facia in middle,forming 2 brownish red maculae on each elytron.Femoral lines subcomplete,reaching 3/4 of sternite posteriorly,extending to anterior corner of abdomen.Genital plates of female genitalia somewhat kidney-shaped with deep notch on inner edge near base (fig.6).Holotype:Male (No.G011),Xizang (Nielamu),1,680-2,250m,1966.Ⅴ.9 (Wang Shu-yong).更多还原
