On the occasion of the centenary of the birth of academician Sándor KOTLÁN, the authors revised the type material of throe dilepidid species: Dilepis yorkei Kotlán, 1923, D. leptophallus Kotlán, 1923 and D. hor- vathi Kotlán, 1923, collected by Lajos BIRO in Papua NewGuinea in 1897-1899, from Megapodius brunneiventris Meyer, 1874 (synonym of M. freycinet affinis Gaim., 1823). The reinvestigation has shown that all three species are valid, only their generic relegation must be changed. Kotlanolepis yorkei (Kotlán, 1923) gen. n., comb, n., Megacirrus leptophallus (Kotlán, 1923) and M. horvathi (Kotlán, 1923) are redescribed and their taxonomy is briefly discussed. The new genus is differentiated from the genera Paradilepis Hsii, 1935, Megacirrus Beck, 1951, Himantaurus Spasskaja et Spassky, 1971 and Dilepidoides Spassky et Spasskaja, 1954. Contrary to MATHEVOSSIAN (1963), M. horvathi is regarded a valid species. The position of M. leptophallus and M. horvathi in Megacirrus needs additional confirmation and could be proved only after a redescription of the type species of the genus - M. megapodii Beck, 1951KEY WORDS. Kotlanolepis yorkei (Kotlán, 1923) gen. n., comb, n., Megacirrus leptophallus (Kotlán, 1923), Megacirrus horvathi (Kotlán, 1923), Cestoda: Dilepididae, Megapodius freycinet, Aves : Galliformes

, NewGuinea. Sándor KOTLÁN (1920, 1923a, b) studied cestodes of birds collected by Lajos BIRO in New Guinea in 1897-1899, and described ten species new to science from the families Anoplocephalidae, Davaineidae and Dilepididae. We have reexamined the type material of three of these species, i.e. Dilepis yorkei Kotlán, 1923, D. leptophallus Kotlán, 1923 and D. hor vathi Kotlán, 1923, which have been referred to various systematic groups based upon their descriptions during the past 65 years, but no one has examined the original types. Just to mention an extreme example, MAYHEW (1925) referred D. yorkei to Oligorchis (Hymenolepipidae) based on the number of testes (usually 4, exceptionally 3). Hence it had become necessary to revise the type materials in order to settle the debate and to redescribe the spe cies. Based on the characters of D. yorkei, description of a new genus, Kotlanolepis gen.n. is given.
