A new species of the genus Pieris Schrank, 1801 (Lepidoptera: Pieridae: Pierinae) with taxonomic notes on the Pieris napi group from India

A new species, Pieris tadokoroi, sp. nov. is described from Himachal Pradesh, India. The new species is closely similar to those of the Pieris napi group and can be diagnosed by its smaller size and a broad apical forewing patch. Based on the recently collected material, the Pieris napi group from India is reviewed. The male and female genitalia are analyzed and illustrated, including the first description of the female genitalia of Pieris extensa bhutya Talbot, 1939. Androconia of all the related species are studied and described.
