Perigrapha (Rororthosia) gyurirani sp. n. Holotype — Male: "Iran, Prov. Fars, 5 km S of Komehr, 5151'10"E, 3027' 15"N, 17.04.1999., 2900 m, leg. Gy. Fábián, L. Nádai and K. Székely" (coll. Gy. Fábián, deposited in the HNHM Budapest). Paratypes — Iran. Prov. Fars: 3 males, with the same data as the holotype; 1 male, Zagros Mts, 10 km E Persepolis, 1000 m, 11.IV.2000., leg. B. Benedek; 3 males, 2 females, Zagros Mts, Küh-e-Barm Firuz, 5 km S Komehr, 3000 m, 12-13.IV.2000., leg. B. Benedek. Prov. Lorestan: 1 female, Bongale, 13.IV.2000., leg. I. Juhász (coll. Gy. Fábián, G. Ronkay, P. Gyulai, HNHM Budapest). Slide Nos RL6784 (male), RL7176 (female). Diagnosis — Externally the new species resembles members of the P. (R.) rorida species-group (i.e. P. (R.) rorida (Frivaldszky, 1835), P. (R.) mundoides (Boursin, 1940), P. (R.) wolfi (Hacker, 1988), P. (R.) sel Ungi Fibiger, Hacker et Moberg, 1996 and P. (R.) wimmeri Hacker, 1996) but is easily distinguished by its more sharply defined, sinuous postmedial line, usually prominent, more or less completely encircled, large orbicular and reniform stigmata, and by the well-discernible discal spot of the hind wing, in addition, the fore wing is more elongate with more acute apex. The male genitalia of the new species differ from those of P. (R.) wimmeri by their shorter, broader, medially strongly dilated valvae with more acute apices, narrower necks of cuculli, shorter, thicker ampullae, shorter, weaker serrate dorsal plate of carina and by smaller bundle of cornuti in terminal part of vesica, consisting of considerably longer, finer spines. The valvae of P. (R.) gyurirani are more asymmetrical, medially more dilated, than those of either P. (R.) rorida or P. (R.) sellingi, and the cuculli are shorter, broader, the ampullae are thicker than is the case of the two congeners. In addition, the shape and size of the fultura inferior, the structure of the carina penis and the diverticula and cornuti of the vesica are also different in the three related taxa. The male genitalia of P. (R.) wolfi are, as yet, unknown. The female genitalia of the new species differ from those of P. (R.) wimmeri (Fig. 10) and P. (R) mundoides (see Hacker & Talhouk 1998, p. 378) by their generally larger size, equally broad ostium and ductus bursae (the ostium of the two related species are considerably broader at junction to ductus bursae), larger, slightly bilobate, strongly ribbed appendix bursae (it is smaller, weaker, simple, weakly ribbed in P. (R.) wimmeri and P. (R.) mundoides) and the larger, elliptical corpus bursae having four, more or less equal signa (P. (R.) wimmeri has small, ovoid corpus bursae with two, strongly unequal signa). The differences between the female genitalia of P. (R.) gyurirani and P. (R.) wolfi (see Hacker, Huber & Kuhna 1988, Fig. 5a) are as follows: the sclerotized part of the ductus bursae of P. (R.) gyurirani is straight, anteriorly slightly dilated, that of P. (R.) wolfi is curved anteriorly, the appendix bursae of the new species is larger, stronger, more ribbed and the corpus bursae is shorter, more elliptical, with prominent signa (the corpus bursae is elongatesacculiform in P. (R.) wolfi and the signa are obsolete). The female genitalia of the fourth species of the subgenus, P. (R.) sellingi (Fig. 12), differ from those of P. (R.) gyurirani by their slit-like, strongly asymmetrical ostium bursae, broader anterior part of ductus bursae having sclerotized ribs on ventral side, much smaller, membranous appendix bursae and shorter, rather globular corpus bursae with four strongly unequal signa. Finally, the female genitalia of the type species of the subgenus, P. (R.) rorida, have (Fig. 11), comparing with those of the new species, broader ostium bursae, more strongly sclerotized anterior part of the ductus bursae and the appendix bursae and the signa are more unequal.
