Magyarország Cnephasia fajai (1.) (Lepidoptera: Tortricidae)

Abstract

The present study aims to gather all the information available on the diagnosis of Cnephasia asseclana, C. chrysantheana species in Hungary, as a starting point for a subsequent paper on the dynamics of distribution limits. The information was mainly derived from lepidopterological collections and faunistic studies. Working with population samples of several taxa one obtains greater variety of information, both qualititative and quantitative. These observations raised at least two problems: (1) it was not possible to report data from localities where two or more species occur sympatrically, and when they could not be positively distinguished by means of morphological characters; (2) in 2010–2014 the author collected museum material from different localities of Hungary; detailed structure of male and female genitalia of several specimens from within the accepted range of nominal Cnephasia was studied, but this provided no quantitative data. Distribution maps of the species show the probable resident distribution area (grey), together with localities from which specimens have actually been examined (black dots). In text of the Hungarian distribution and phenology, detailed information is also included about flight period, biology including foodplants and habitat including the altitude range. Structure of genitalia and morphological characteristics of wings are illustrated with figures. Colour photographs and drawings of adults and genitalia of both sexes are provided for identification of each described species. Ample illustrations of differential features will facilitate identification. At present, 12 Cnephasia species are known from Hungary, and are included in the Checklist, together with the most important synonyms. The study series is intended for both amateurs and professionals as well as for those engaged in applied lepidopterology. With 24 figures.
