Introduction The leaf-roller (Tortricidae) fauna ofthe Volgo-Ural region is moderately well known. Eversmann (1844) made thorough faunistic investigations mainly inthe southern Urals in the middle ofthe century and listed 132 species ofTortricidae for this region. The vicinity of Sarepta in the Lower Volga region was intensively studied at the end ofthe 19^^ century by Hugo Christoph (Amsel 1964) and some other entomologists, and numerous new species were described from there (Christoph 1872; Kennel 1900; Staudinger 1871, 1877). From the beginning of the 20* century there have been no serious studies ofmicrolepidoptera in the Volgo-Ural region until 1996, when research inthesouthernUralswascommencedbytheauthorandseveralcolleagues.Themajority ofthe findings from about 30 expeditions made between 1996 and 2011 in the region remain unpublished. Anikin et al. (2006) summarised the data on Tortricidae from the Volgo-Ural region, which include 510 species. However, their list lacks several species recently recorded in the steppes ofthe southern Urals. In the present article, faunistic and/or taxonomically significant new records ofnine species ofTortricidae from the region are reported. Material and methods This contribution is based on material collected by the author during 1996-2006 on about 30 expeditions to the southern Urals and the Lower Volga region, three ofthem jointwithTimoNupponen.Thematerialwascollectedbothbyartificiallight(ultraviolet tube lamps: Philips TL K 40W/ 09N, Sylvania blacklight 20W & 40W/350 BL; solar lamp Osram Ultra Vitalux 300W) at night and by netting and sweeping during the & daytime. The material is deposited in the private collection ofT. K. Nupponen.

(Photos: K.Nupponen). following abbreviation is used in the text: ZIN (Zoological Institute, RussianAcademy ofSciences, St. Petersburg, Russia). Systematics Pelochrista maculiferana (Kennel) was described from a single male specimen col- lected in the Guberlinsky Mountains, South Ural in 1892. No additional specimens have been reported since. Razowski (1999: 481) synonymised maculiferana withEpi- blemajunctanum (Herrich-Schäffer, 1856), and this opinion was followed in several & subsequentpublications (e.g., Razowski 2001, 2003; Sinev Nedoshivina2008; Lepi- forum 2011). During an expedition to the southern Urals in late June 2003, I collected two male specimens ofa peculiar small tortricid moth in the Guberlinsky Mountains, Orenburg district. After dissecting one of them, it became obvious that the genitalia exhibited characteristics typical for the genus Pelochrista (see Razowski 2003). However, I was A unabletofindacomparable illustrationinthe literature. fewyears later, I studiedleaf- rollers in the collection ofZIN with special attention to two specimens ofPelochrista maculiferana, which were externally identical to the newly-collected specimens from southern Ural and were collected from the same locality. The specimens were not dissected, but the valvae ofthe holotype were sufficiently exposed to see the essential characteristics (see below). Based on facies and male genitalia, these two specimens are undoubtedly conspecific with the holotype ofmaculiferana. The labels ofthe type specimens ofP. maculiferana are somewhat confusing. The descriptionisbasedonasinglespecimenlabelled"Guberli, 19.6.1892,Christoph[leg.]". The holotype in ZIN lacks the label with date and collector, and the red holotype label is not the original one. The second specimen is labelled as paratype, but no paratypes were designated by Kennel (1900). The habitats in the Guberlinsky Mountains are steppe hills with steep, xerothermic rocky slopes (Fig. 1). The recently-collected specimens were swept in late afternoon Notalepid.35(2): 115-124 117 KOJi. 6. Bei. Kh, HîîKojiaa Maxaâ^OBHHa Photograph Mà-ekKopeé Fig.3. ImagoofPelochristamaculiferana(Kenn.)

The known specimens ofP. maculiferana have been observed in the second halfofJune, but the flight period probably extends into mid-July. The species is known only from the type locality, the Guberlinsky Mountains in the southern Ural range. The redescription ofthe moth and description ofthe male genitalia are given below.

P. maculiferana is rather easily distinguished from other known species of the genus Pelochrista both externally and by the characters in the male genitalia. The moth is small, and the rusty brown forewings with a distinct dorsal patch surrounded by large dark blotches are characteristic. The male genitalia are unmistakeable, and readily separated from the other known species ofPelochrista by a very thick neck of the valva and a rounded cucullus with one ventral and two distal spines. In the original description ofP. maculiferana, the species was compared to E.junctanum. In the latter species, the forewings are greyish or fuscous, the dorsal patch is wider and not divided into two areas, the dorsal blotches are smaller and blackish, the hindwings are much paler, and the male genitalia are completely different.

The species inhabits desert steppes and semideserts in the northern Caspian Sea region. The flight period extends from the last third ofAugust to late September.

Female, wingspan 22 mm; Lower Volga, by Ilovla village5.ix.2002). The larva feeds on Caroxylon laricinum (Pall.) Tzvelev (Chenopodiaceae) (Anikin et al. 2006). P. exasperantana is easily distinguished from related species by its ochreous forewingswithwell-defineddarkbrownsubterminalandmedianfasciae,thedorsalpart ofthe latter is verybroad forming a roundish blotch. The male and female genitalia are illustratedbyRazowski (2002: pi. 6 fig. 58; pi. 44 fig. 58). The two adults illustratedby Razowski (2002: pi. IVfigs 58 & 58a) as exasperantana are actuallyP. krulikowskii (Obraztsov, 1944). P. exasperantana has less elongated ochreous forewings, with a dorsallybroadand subcostallycutoffdarkbrownmedian fascia. Basedonexamination ofa lot ofmaterial ofboth species (several hundreds ofP. krulikowskii from S Ural, W Lower Volga, and Kazakhstan, and over 30 exx ofP. exasperantana from Lower W Volga and Kazakhstan), it is clear that P. krulikowskii is externally a very variable species. It seems that specimens that are somewhat doubtful as to their identification are usually mottled forms ofP. krulikowskii, and not P. exasperantana. With this on mind, the two species are fairly easy to separate from each other both by the external appearance and by the male genitalia. Eugnosta medvedevi(Gerasimov, 1928) Fig. 7 Material.
