簡介:"Antennae of Speidelia formosa both sexes filiform, collar producing large, peaked hood. Male: Head and thorax ash-grey, mixed with brownish and a few whitish hairs. Lateral sides of palpi, frons, collar and tegulae marked with dark grey-brown. Abdomen somewhat paler, more brownish, second segment with dark brown dorsal tuft. Forewing elongate, narrow, with apex finely pointed. Ground colour shining, pale ash-grey with fine bluish- violaceous shade and variably strong, dark greyish-brown irroration; scaling finely reticulate. Hindwing, slightly transparent, whitish; veins, discal spot and narrow marginal suffusion darker brown. Female similar, larger in size, forewings somewhat broader, dark suffusion of hindwing significantly stronger. S. formosa differs from S. taiwana and S. semialba by its much paler forewing ground colour with more conspicuous outlines of the stigmata and the dark streaks defining the subterminal line. The hindwing of S. formosa is slightly paler than that of S. taiwana while the hindwing of S. semialba is much cleaner than those of S. formosa and S. taiwana, it is pure white, without dark covering of veins. The description of this species based on the description of Ronkay(2000). Speidelia formosa雌雄觸角皆為絲狀。領節具大型鳥喙狀突起,雄蟲頭部和胸淡灰色,摻雜棕色與少許白色毛。下唇鬚側邊、額、領節和肩板暗灰棕色 。腹部色稍淡,更呈棕色,第二節具暗棕色叢毛。前翅長且窄,端部變尖,底色亮淡灰色,具細微的藍紫羅蘭色色調和濃淡有變異之暗灰棕小斑點,鱗片呈細微網狀。後翅略呈透明白色,翅脈、盤狀點和窄的邊緣區域佈滿較暗的棕色。雌蟲與雄蟲類似,但在體型上較大,前翅略寬,後翅明顯顏色較暗。 S. formosa 與S. taiwana 和 S. semialba 不同處在於前翅底色更淡,且具有明顯之翅紋和在亞端線上具明顯之暗條紋。S. formosa 後翅較S. taiwana 後翅略淡,而S. semialba 後翅則較 S. formosa 和 S. taiwana後翅更潔白,為純白色,翅脈上不具暗色條紋。本種敘述主要引用Ronkay(2000)之文獻內容為主。 "
