Discovery of a New Pierid Butterfly, Aporia Gigantea Cheni Hsu and Chou (Lepidoptera: Pieridae), from Taiwan

臺灣截脈絹粉蝶Aporia gigantea cheni ssp. nov.之發現

Abstracts


本文根據從臺灣中央山脈南段獲得之材料記述及圖示一大型粉蝶截脈絹粉蝶的新亞種。與分布於中國大陸西部的原亞種比較,臺灣亞種的色澤較黑、體型較小,且翅膀斑紋樣式缺乏雌雄二型性。此大型新亞種蝴蝶之發現說明臺灣地區的蝶相雖經一世紀以上的調查,仍未完備。截脈絹粉蝶在臺灣之發現可視為動物地理上隔離分布又一良好例證。本新亞種之亞種名係紀念發現者鞘翅目昆蟲研究家陳常卿先生。

A new subspecies of a large-sized pierid butterfly, Aporia gigantea cheni, is described and illustrated based upon material collected from the southern portion of the Central Range of Taiwan. Compared to the nominotypical subspecies of A. gigantea of western China, the new subspecies is darker, smaller, and lacking sexual dimorphism in wing patterns. The discovery of a new subspecies of a large butterfly reveals that the inventory of the butterfly fauna of Taiwan is still far from being complete. This butterfly also serves as a good illustration of zoogeographic disjunction in its distribution.
