簡介:"Perigrapha nigrocincta頭部及胸部淡赭灰色或青灰色,下唇鬚及前額為黑灰色,腹部的軟毛相當均質。雄蟲觸角為短雙櫛齒狀,雌蟲為絲狀。腹部顏色較黑且更多棕灰色,背方飾毛缺如。前翅相當短且高,頂角尖銳,外緣為平坦拱型。前翅底色亮淺赭灰色或青灰色,具微深之棕色斑點及紅色鱗片,特別是中央區域。後翅亮白赭色,內側顏色較淺,翅緣區強烈佈滿深灰棕色。本種原被誤鑑定為Cerapteryx conspecta(Wileman)。P. nigrocincta 在Perigrapha屬中相當特殊,因淡赭灰色前翅上具黑色癒合之圓形及腎形紋,且圍莖膜相對較短和迴旋狀較少,及末端具有兩個角狀器。至目前為止,本種的生態習性及寄主植物未知。本種敘述主要引用Hreblay and Ronkay(1997)所發表文獻內容。Perigrapha nigrocincta head and thorax pale ochreous grey or slate-grey, palpi and frons marked with blackish grey, pubescence of thorax rather homogenous. Antennae of male very shortly bipectinate, those of female filiform. Abdomen somewhat darker, more brownish grey, dorsal crest absent. Forewing rather short, high, with apex acute, outer margin evenly arcuate. Ground colour shining, pale ochreous grey of slate-grey, irrorated with a few darker brown and reddish scales, mostly in medial area. Hindwing shining whitish-ochreous, inner area slightly, marginal field strongly, suffused with dark grey-brown. This species was incorrectly identified as "Cerapteryx conspecta" Wileman. P. nigrocincta is unique within the genus Perigrapha in having a pale ochreous grey forewing with fused, black orbicular and reniform stigmata and relatively short, less helicoid vesica armed with two terminal cornuti. The description of this species based on the description of Hreblay and Ronkay(1997)."
