On Photinia-associated Chrysozephyrus Hairstreaks, with Description of a New Species (Lepidoptera: Theclinae: Theclini)

以石楠屬植物為寄主的Chrysozephyrus屬灰蝶及其一新種

Abstracts


雖然近年來薔薇科植物被發現是鱗翅目灰蝶科Theclinae亞科Theclini族之中多樣性最高的Chrysozephyrus屬的重要幼蟲寄主,但是在薔薇科中種類甚多的石楠屬Photinia植物迄今尚未有所研究。本研究以石楠屬植物為幼蟲寄主之Chrysozephyrus屬兩種,包括一新種,並述及其幼期形態與生物學。此兩種灰蝶呈同域分布,但幼期微棲所相異。形態資料亦顯示兩者親緣關係不近,因此其利用石楠屬植物為寄主可能並非來自同一起源。

While plants in the Rosaceae have recently been recognized as important hosts for Chrysozephyrus, the most diverse genus within the tribe Theclini sensu Eliot (1974), hitherto Photinia has not been known as a larval host for this genus. An investigation of various Photinia species revealed 2 Chrysozephyrus species associated with this fairly diverse group of trees, namely C. shimizui Yoshino and an undescribed species. The new species is described herein, and information on the immature morphology and biology of both species is also provided. The 2 Chrysozephyrus species occur sympatrically, but each is specialized in choice of microhabitat. The morphology of the immatures suggests that the 2 species do not form immediate sister groups to each other, thus their host usages might not be of a single origin.
