Perigrapha (Perigrapha) heidi Hreblay, 1996 , Esperiana , 4: 70, figs 3, 4, 21 (genitalia), pl. E: fig. 4 (adult) (Type locality: [ Tajikistan, Hissar Range , Romit Nature Reserve ] “USSR, Tadzhikistan, 39°N 68°40'E, Hissarskij mts., Romit, 1100m ”).

Material examined. Paratype: male, USSR , Tajikistan, 39°N 68°40'E, Hissar Mts , Romit, 1100m, 21.IV.1991, U. Jūrivete leg., gen. slide No.: 4062 (prepared by Hreblay) ( MH / HNHM) . Non-type : 2 males, 1 female, Tajikistan, Hissar Mts , Varzob Range , Takob valley at Poshum village, 1700m, 38°52'20''N 69°55'47''E, 11–12.IV.2015, B. Benedek leg., gen. slide No.: JB2377 ♀ (prepared by Babics) ( BBM) .

Diagnosis. The forewing length is 18.0–19.0 mm in both sexes. Perigrapha heidi is morphologically most similar to P. belyalovi sp. n. and the detailed comparison is provided above in the diagnosis of the latter species. It is also largely reminiscent of P. centralasiae but in most cases can be distinguished by its somewhat larger size and slightly longer rami of male antenna. However, as in Tajikistan some specimens of P. centralasiae are as large as P. heidi , the reliable identification requires examination of the genitalia structures. In the male genital capsule, P. heidi differs from P. centralasiae in the more distally dilated uncus, the longer and somewhat narrower ‘neck’ of the cucullus, the more symmetrical cuculli with shorter, distally broader, and apically rounded ventral lobes (they are apically pointed in P. centralasiae ), and the somewhat larger left dorsal lobe of the cucullus. The phalli of two species are alike. The vesica of P. heidi is somewhat longer and more helicoid than in P. centralasiae . In the female genitalia, P. heidi is distinct from P. centralasiae in the longer and posteriorly narrower ductus bursae, the markedly larger corpus bursae, the considerably narrower posterior sclerotised plate of the corpus bursae, and the somewhat longer and distally narrower appendix bursae. Additionally, the lateral right signum of P. heidi is elliptical and large whereas in is very small and rounded in P. centralasiae .

Distribution. The species is currently known only from Hissar Range in Tajikistan ( Hreblay 1996; Benedek et al. 2021).
