Paramartyria anmashana Hashimoto, 2000 鞍馬山小翅蛾
鞍馬山小翅蛾(Paramartyria anmashana)是小翅蛾科(Micropterigidae)的成員,目前僅知分布於臺灣大雪山森林遊樂區(鞍馬山)。本種的頭部為橙黃色,鱗片立起,觸角粗,複眼比例大,呈銀色,胸部與腹部為黑色,前翅為深藍紫色底,靠前緣有兩塊白斑,停棲時自然光下可見金屬光澤,後翅為黑色,無其他翅紋。全世界的小翅蛾科目前估計約有21屬160種,臺灣則有其中的2屬11種,分別是小翅蛾屬(Paramartyria)和古小翅蛾屬(Palaeomicroides)。臺灣的小翅蛾屬共記錄4種,目前都僅知分布於臺灣。鞍馬山小翅蛾和圓斑小翅蛾(Par. maculatella)的翅紋與雄性生殖器十分相似,加上目前仍有一個未紀錄種翅紋也是如此,因此本種目前無法僅靠翅紋鑑定,必須搭配地點與發生時間,而生殖器比對則是較可靠的方法。雖然TaiBNET中的鞍馬山小翅蛾被置於古小翅蛾屬下,然而筆者無法找到該處理的原始文獻,加上鞍馬山小翅蛾的特徵吻合小翅蛾屬,因此本文依循Hashimoto的原始處理。圖中的個體來自大雪山森林遊樂區遊客服務中心,2014年7月。

Hepialiscus taiwanus Ueda, 1988 臺灣蝠蛾
臺灣蝠蛾(Hepialiscus taiwanus)是蝠蛾科(Hepialidae)的成員,僅知分布於臺灣,目前除了一份來自上巴陵的正模標本紀錄,未有其他正式紀錄。本種頭部與前胸為黑褐色,中胸至腹部為黃褐色,觸角甚短且腹眼比例大(此為蝠蛾辨識時的重要特徵),前翅狹長,黃褐色底,外中線位置有三枚白斑(紅色箭頭),推測為本種的辨識特徵,後翅為黑褐色底,與前翅形狀近似,無其他翅紋。根據Hampson(1892)的研究,Hepialiscus的定義特徵在於前後翅的R2、R3與R4翅脈共柄。本屬全世界已知4種(Nielsen et al., 2000),在臺灣則紀錄其中3種(Ueda, 1988)。根據Ueda(1988)的研究,臺灣的三種Hepialiscus白斑各有不同,是除了生殖器外可做為辨識依據的特徵,惟蝠蛾科翅紋一般來說變亦可能很大,比對生殖器是比較可靠的作法。圖中個體來自拉拉山,2010年11月。
A Brief Introduction
Hepialiscus taiwanus represents one of the three Hepialiscus species in Taiwan and is characteristic by the white spots (as red arrow) from the others. Up to date, only one specimen of this species was known and described as the holotype. The individual in present article may be the second specimen of Hepialiscus taiwanus in Taiwan.
