Description

It is similar in appearance to the gatekeeper (P. tithonus), which is found further north, and the Spanish gatekeeper (P. bathsheba). The gatekeeper has spots on the underside of the hindwing which the southern gatekeeper lacks. The Spanish gatekeeper has quite a different underwing pattern with a prominent while band.

Sexual dimorphism

The southern gatekeeper, like many in subspecies Satyrinae, exhibits sexual dimorphism. The male is smaller than the female, the front wing of the male is 15 to 16 mm whereas a female front wing is 20 mm, and has a patch of scent-producing scales known as the androconia, which can be seen as a dark patch on the upperside of the forewing.
