Thubana deltaspis Meyrick, 1935 盾白斑折角蛾

盾白斑折角蛾(Thubana deltaspis)是折角蛾科(Lecithoceridae)瘤折角蛾亞科(Torodorinae)的成員，分布於中國與台灣。本種的前翅為灰褐色底，前緣中央有一塊鵝黃色的三角斑，後翅為灰色，無其他翅紋。白斑折角蛾(Thubana)主要分布在東南亞地區，目前記錄超過30種；在台灣目前共紀錄三種，近期相關的分類研究工作主要由Park(2000, 2001)完成。本種與另一個目前未記錄於台灣的種類─微白斑折角蛾(T. microcera)，但可輕易由頭頂的顏色區分兩者：前者為淡褐色，後者為乳白色。本種在台灣屬於常見種。

T. microcera which is not recorded in Taiwan, has very similar wing pattern with T. deltaspis: dark ground colour and an white triangular marking along anterior margin of forewing. However, the head of T. deltaspis is brown while T. microcera is ochreous white.
