average (this rate is 2.81 in T. pilosus), the apical part is more acute. Outer third of fore wing with continuously broadened, wrinkled margin running from apex of clavus towards pterostigma, its width (ma) always smaller than that of costal margin at middle of wing (s); ma < s. This is a good key feature for the species as this rate is just the opposite in the two related species. Male genitalia and anal tube (Figs 4-14): The configuration of the anal tube (Figs 810) is similar to that of T. pilosus, its apical part asymmetrical, its left lobe (from caudal view) is almost three times as long as right lobe, both lobes projecting downwards. The páraméra show no differences comparing with those of the related taxa. Aedeagus (Figs 4-6) with two subbasal sclerotized teeth ventrally (Fig. 5); medial part of phallosoma with slightly curved appendix projecting forward and downwards; apical part of aedeagus with two lateral appendices and with terminal "banner". Right lateral appendix slightly curved, running parallel with phallosoma towards internal part of body; left lateral appendix about half as long but strongly curved, almost S-shaped. The shape and position of these appendices are good distinctive features comparing with those of £ pilosus. The terminal part of the aedeagus, the "banner" is strongly sclerotized, originating from the left side of apex of aedeagus, being spatulate at elbow, running to the right side over phallosoma. The variation of these structures is rather small (see Figs 11-14). The female genitalia of T. soosi show no remarkable differences comparing with those of T. pilosus, only slightly paler, ochreous brown in colouration. Identification key to the three Hungarian species 1. Medial part of phallosoma with three appendices T. desertorum Medial part of phallosoma with one appendix only 2. 2. Left lateral appendix of phallosoma slightly curved, projecting towards internal part of body, its tip extending near to basal part of aedeagus T. pilosus Left lateral appendix of phallosoma strongly curved, almost S-shaped, its tip not extending over origin of medial appendix T. soosi The new species is dedicated to the memory of the late Dr. Árpád Soós, Curator of the Hemipteran collections of the HNHM, Budapest, who with great patience had led me into the taxonomy of Homoptera. ClCADELLIDAE Rhopalopyx brachyanus sp. n. (Figs 16-31) The intense collectings made in the area of the Körös-Maros National Park, SE Hungary, produced a large amount of Cicadellidae specimens. This material was taken with netting and with D-Vac traps, collected mostly in loessy and saline grasslands. One of the dominant species of this material was Rhopalopyx vitripennis (Flor, 1861), represented by a large stock of specimens. Some of these specimens, however, show conspicuous morphological differences compared with the "typical" ones. The correct identification of the two different "vitripennis" required to clarify the identity of R. vitripennis sensu Flor as well as the study of the range of variation of R. vitripennis (see the
