綜合描述
廬山棕旋蛾(Dichomeris lushanae)是旋蛾科/麥蛾科(Gelechiidae)棕旋蛾亞科(Dichomeridinae)lushanae種群的成員。本種的前翅為褐色底，中室有兩枚黑斑，較靠中室頂端的黑斑較長；後翅為灰白色，無其他翅紋。棕旋蛾屬的介紹請參考本站物種說明─Dichomeris bucinaria藍紋棕麥蛾。Park & Hodges在1995年的研究裡一共檢視了7份各地的廬山棕旋蛾標本，牠們分別來自臺北松山(正模)、新竹觀霧、南投廬山、蓮華池、梅峰、臺南關仔嶺與高雄chiahsien。
A Brief Introduction:
Dichomeris lushanae represents one of the 32 Dichomeris species in Taiwan and shares similar wing pattern with D. loxospila: relatively simple wing pattern with brownish ground colour and two dark spots on forewing. The former species could be distinguished from the later by a longer dark spot on the tip of cell. This wing pattern is also shared by some species of Lecithocera (Lecithoceridae), and scales on labial palpa are a useful charater to identify them.

外觀相似性
廬山棕旋蛾翅紋雖然簡單，但在臺灣產的棕旋蛾屬中僅有D. loxospila的翅紋也是除黑點外無其他特別顏色或斑紋，而兩者可由以下特徵區分：後者的斑紋為中室靠翅基的黑斑較長，與前者恰好相反。反倒是折角蛾屬(Lecithocera)的種類大多有跟本種相同的翅紋，容易混淆，須仔細檢視下唇鬚特徵：本種的下唇鬚第二節背方鱗片豎起，且未向上舉起超過頭部。
