Discovery of a new pierid butterfly, Aporia gigantea cheni Hsu and Chou (Lepidoptera : Pieridae), from Taiwan

Discovery of a new pierid butterfly, Aporia gigantea cheni Hsu and Chou (Le pidoptera: Pieridae), from Taiwan. Zoological Studies 38(2). 222-227. A new subspecies of a large-sized pierid butterfly, Aporia gigantea cheni, is de scribed and illustrated based upon material collected from the southern por tion of the Central Range of Taiwan. Compared to the nominotypical subspeci es of A. gigantea of western China, the new subspecies is darker, smaller, and lacking sexual dimorphism in wing patterns. The discovery of a new subs pecies of a large butterfly reveals that the inventory of the butterfly fau na of Taiwan is still far from being complete. This butterfly also serves a s a good illustration of zoogeographic disjunction in its distribution.
