【摘要】 松毛虫属变异较复杂,过去文献上的记载比较紊乱,本篇着重以各虫期的形态特征为主,修订记载了我国严重为害松柏科的6种松毛虫,计:西伯利亚松毛虫(Dendrolimus sibiricus Tschetv.),赤松毛虫(D.spectabilis Butler),马尾松毛虫(D.punctatus Walker),铁杉毛虫(D.superansButler),云南松毛虫(D.latipennis Walker),和思茅松毛虫(D.kikuchii Mats.),同时记述了2个新种,计:油松毛虫 (D.tabulaeformis Tsai et Liu)和西昌松毛虫(D. xichangensis Tsai et Liu)及1个新亚种:赭色松毛虫(D.kikuchii ochraceus Tsai et Liu)。模式标本保存在中国科学院动物研究所。 新种油松毛虫和赤松毛虫、马尾松毛虫很近似,但其成虫前翅较狭长,中横线与外横线为白色,亚外缘斑列内侧有白色斑;外生殖器小抱针长度约为大抱针的1/2;外生殖器侧前阴片接近圆形。卵壳上内层室和中层室壁很薄,外层室中央凹下部分呈不规则条状。幼虫毛片束发达,片状毛小,先端极少有齿状突起,无贴体倒伏鳞毛。 新种西昌松毛虫和云南松毛虫、思茅松毛虫比较近似,但成虫前翅中横线与外横线之间明显形成褐色宽带;外生殖器前阴片愈合成一块。卵壳表面无花斑。幼虫胸部背面无明显毒毛带,但体侧有黑丛毛。根据以上几点,显然和其他两种松毛虫有区别。 新亚种赭色?更多还原

【Abstract】 Six known species, two new species and one new subspecies are described, which arecollected in China, and all belonging to the genus Dendrolimus Germar. The charactersused for the identification of species are: the patterns of the forewing, the structure of thescales and genital organs; the size and structures surrounding the micropyle of the eggs;tufts of the subdorsalis anterior of the mature larvae and the shapes of the pupal cre- masters. Besides, keys to adults, eggs and larvae are prepared separately, each basedupon the more common and conspicuous characteristics. Types are preserved in theMuseum of the Institute of Zoology, Academia Sinica, Peking. Dendrolimus tabulaeformis Tsai et Liu, n. sp. Colour variable, being pale greyish brown to deep brown. closely allied to D.punctatus Wk., but with distinguished transverse stripes and not strongly curved costalmargin on the primaries. Submarginal line broken into black spot-series, to line through2 spots in the 1st and 2nd interspaces crossed with the termen. white discocellularspot on primaries much clear than ; transverse stripes distinct; submarginal black spot-series is defined internally by reddish brown colour which is quite different from thatof D. punctatus. Minor harpe. of male genitalia approached to 1/2 the length of the major;mid-antevaginalis of female genitalia large, latero-antevaginalis nearly round. Micropyleend of the eggs without distinct protuberance; surrounding micropyle with 2--3 layers ofinner-layer cells; outer-layer cells with irregular stripe like central invaginations. Abovethe mid- and metathoracic segment of larvae with black belt-like hairy scales; tufts ofsubdorsalis anterior strongly developed; the base of tufts not covered with spindle-shapedscales, only with black hairs; spatulate hairs small, scarcely with dental ends.: length,20—28 mm.; exp., 45—61 mm. : length, 23—30 mm.; exp., 57—75 mm. Holotype: , Hopeh: Lanping (1961, Ⅷ, 2), allotype: , Peking (1955, Ⅶ,21), paratype: 15 specimens (,) from various localities of Hopeh and Liao-ning provinces. Dendrolimus xichangensis Tsai et Liu, n. sp. Primaries light brown; median and postmedian lines deep brown, the interspacebrown; costal margin 1/3 near the apex strongly curved; outer margin wavy. Submarginalline broken into black spot-series, to line through 2 spots in the 1st and 2nd interspacescrossed with the apex. Minor harpe of male genitalia strongly chitinized, with a 90°turning, closely connected with major, mid-antevaginalis and latero-antevaginalis of fe-male genitalia fused together. Micropyle end of the eggs without distinct protuberane;surrounding micropyle without middle layer cells; outer layer cells without central in-vaginations; corner-setae sometimes not distinct, but with distinct basal papilla. Abovethe mid- and metathoracic segment of larvae without black belt-like hairy scales; lateralside of each abdominal segment with black tufts. : length, 37 mm.; exp., 60 mm.: length, 37 mm.; exp., 78 mm. Holotype: , allotype: , Szechuan: Xichang (1959). Dendrolimus kikuchii ochraceus Tsai et Liu, n. ssp. The characters used for the identification of this subspecies are closely allied to D.kikuchii Mats., but with distinguish dark brown color in , distributed in Hunan andKiangsi provinces, with Pinus massoniana Lambert as its hostplant. : length, 38 mm.;exp., 62 mm. : length, 38 mm.; exp., 83 mm. Holotype: , allotype: , Kiangsi: Yifeng (1959, Ⅶ, 3).更多还原
