FOLIA ENTOMOLOGIC/ HUNGARICA ROVARTANI KÖZLEMÉNYEK XLVIII 1987 p. 243-244 Tephritis dudichi Aczél (Diptera: Techritidae), lectotype designation and diagnosis By I. M. WHITE and F. MIHÁLYI (Received April 30, 1987) Abstract: Tephritis dudichi Aczél (Diptera: Techritidae), lectotype designation and diagnosis. - The syntypic male of Tephritis dudichi Aczél is designated as the lectotype. The characters separating T. dudichi from similar species are listed and its aculeus is illustrated for the first time. ACZÉL (1939) described Tephritis dudichi based on a male and a female reared from Telelda speciosa (Schreber) Baumg., from south-west Romania. ACZÉL noted that the specimens were placed in the Természettudományi Múzeum (Hungarian Natural History Museum), Budapest (TMB), but he failed to state that one specimen was a holotype. In the 1940' s ACZÉL borrowed most of the material of Tephritis for examination at The Hungarian Plant Protection Institute, where he worked. Unfortunately, this building was destroyed by wartime activity during the winter of 1944-45 and so the female syntype, which was part of the loan to ACZÉL, was destroyed. However, the male syntype, labelled as a "paratype", was recently discovered in the E.M. HERING collection at the British Museum (Natural History), L»ndon (BMNH). Dr. A. SOÖS (TMB) recollected that HERING had borrowed the male, although there was no way of confirming the details of the loan because the Természettudományi Múzeum lost their correspondance in a fire in 1956. However, the syntype male, which is here designated as the lectotype of Tephritis dudichi, has now been returned to the Természettudományi Múzeum in Budapest. Further specimens of T. dudichi were discovered in eastern Romania in 1983, and like the type specimens, they were reared from the composite Telekia speciosa (Asteraceae, Inuleae). ACZÉL (1939) gave a long and detailed description of T. dudichi , largely based on the lost female paralectotype, and he presented a clear photograph of the male lectotype. Subsequently, T. du dichi was included in a key to World Tephritis species by HERING (1944) and a key to the Hungarian members of the genus by MIHÁLYI (1960). However, these description and keys do not include details of the female' s aculeus tip shape, which White (1987) has shown to be of importance in the identification of many European Tephritis species. Consequently, the aculeus Is figured here and some diagnostic notes are given to facilitate the separation of T. dudichi from similar European species. Tephritis dudichi Aczél, 1939: 124. Type locality: ROMANIA, near Resita, Valiug. Using the key to British Tephritis species by WHITE (1987) T. dudichi runs to couplet 10, which separates T. leontodontis (De Geer) and T. neesli (Meigen); other European species not included in the key, but known to run to this couplet are T. cirsicola Hering, T. cornupunctata Hendel, and T. fallax (Loew). This group of at least six species, including T. dudichi , may be differentiated from other European Tephritis species by the following combination of characters: Wing extensively marked, markings not confined to an apical star-shaped mark. Without a complete preapical hyaline stripe (except in some individuals of T. cirsicola and T. cornupunc tata ), but with an apical forked mark that joins the apices of veins R4+5 and M.
