文獻：Wu, S. Chang, W. C., Owada, M & Nakajima, H. 2013. Phigaliohybernia fulvinfula Inoue, 1942, the third winter geometrid moth recorded in Taiwan (Geometridae, Ennominae). Japan Heterocerists' J. 268: 455-456.
Abstract
The fauna of winter geometrids in Taiwan was explored in the previous studies (Nakajima, 1990; 1994) and only two species, i.e. Operophtera brunnea Nakajima, 1991 (= O. variabilis Nakajima, 1991) and Phigalia owadai Nakajima, 1994 were recorded. Recently we collected a male specimen belonging to the genus Phigaliohybernia Inoue, 1942 in Xicun (1,090m), northern Taiwan. Having compared to P. fulvinfula Inoue, 1942, an endemic species ranging in Honshu, Shikoku and Kyushu, Japan (Nakajima,1998; Sato, 2011), we proved the Taiwanese and Japanese specimens are conspecific. Therefore, the recent discovery gave new biogeographic evidence showing the range extension of P. fulvinfula, also the third winter geometrid moth recorded in Taiwan. The single specimen was deposited in Insect Collection, Taiwan Forestry Research Institute, Taipei, Taiwan (TFRI).
簡介
台灣產冬尺蛾類(註一)之生物相研究中，過去曾有新種大和田扉冬尺蛾 (Phigalia owada Nakajima, 1994)的描述以及灰褐波冬尺蛾 (Operophtera brunnea Nakajima, 1991)的紀錄。隨著近年來相關研究人員於中高海拔進行低溫期燈光誘集調查，台灣冬尺蛾類之物種多樣性和與鄰近區系近緣種之親緣關係正逐步明朗化。本篇文章首次紀錄第三種冬尺蛾類群，即黃褐類扉尺蛾(Phigaliohybernia fulvinfula Inoue, 1942)，而此種目前僅有一隻於三月中旬，採自桃園西村低中海拔闊葉原生林帶(1090公尺)之雄蟲標本。
