Pieris napi muchei Eitschberger, 1983

Pieris napi muchei Eitschberger, 1983; Herbipoliana 1(1-2): 135; TL: "Kasachstan, Alatau, Almaarasan Umgeb., 1900-2100 m" (original description)

Description.

Both wings pure white on the upperside, and bright yellow on the underside. Spring form: male (Fig. 11I, J ): apical spot blackish, triangular, extending along veins to outer margin without merging or suffusion. The 1st, 3rd and outer spot distinct (2nd discal spot absent and 3rd discal spot sometimes faint) on the upperside. Summer form: male (Fig. 11K ): both wings clearly whitish without dark powder along veins, the 1st discal spot and outer spot strongly developed and the 3rd discal spot merging with the apical spot as a square on the upperside. The 1st and 2nd discal spot distinct on the underside. Females (Fig. 11L ) resemble males but with all dark markings more developed.

Distribution.

East Kazakhstan; Kyrgyzstan; Uzbekistan; Tajikistan

Phenology.

Flies from April to September, bivoltine or trivoltine ( Tuzov et al., 1997).

Male genitalia.

(Fig. 5F ) terminal part of tegumen without lobe shaped convex; basal part of uncus slightly narrowed as terminal part of tegumen; uncus moderately convex at its median part.

Female genitalia.

Not examined.

Note.

This subspecies can be easily distinguished from all other taxa distributed in the same region by the mostly distinct 3rd discal spot on the upperside and bright yellow color on the underside. The whitish wings without any dark powder of the summer form also make this subspecies very easy to identify. Unfortunately, we did not find any female specimens of its spring form. Future field surveys are essential to clarify this issue.
