Dr. Murai Éva szerk.: Parasitologia Hungarica 20. (Budapest, 1987)
MATERIAL AND METHOD Sándor KOTLÁN' s scientific career is tied to the Department of Parasitology of the University of Veterinary Science in Budapest (see KASSAI and HOLLÓ, 1987, on pp. 5-10 of this issue). On the occasion of the centenary of his birth the helminths studied and described by him were donated by the University to the helminthological collection of the Hungarian Natural History Museum. The material was originally collected in New Guinea by the reknowned collector Lajos BIRO for the Hungarian Natural History Museum who was in contact with István RÁCZ, who described three new cestodes from New-Guinean Varanus in 1920. After the early death of RÁCZ the material handed over to him by BIRÓ was studied by KOTLÁN, and up to the death of BIRO in 19 31 through personal contact helped him in studying the rich cestode material from birds. Lajos BIRÓ collected in New Guinea for the museum in 1897-1899. The three species dealt with here originate from a single common scrub hen, Megapodius freycinet (previously known as M. brunneiventris - Galliformes). The host was collected in the locality FriedrichWilhelmshafen, a settlement near Port Moresby in the German colony of that time. BIRÓ collected the parasites from the bird himself and probably preserved them in alcohol before transporting them to Europe (see SZÉKESSY, 19 56 as regards the expeditions of L. BIRÔ) KOTLÁN stained the specimens in alcoholic borax carmine, and even today they are in excellent condition. Longitudinal and cross-sectional series were made with haematoxylin-eosin staining. Further specimens were found preserved in 4% formaldehyde solution. The specimens originally collected from a single host were preserved in three tubes, sorted to the species and with hand-written labels, hence they are treated as type specimens. New whole mount preparations were made with iron-acetocarmine method (GEORGIEVet al., 1986) of five of the 8.1, Dilepis yorkei , eight of D. horvathi and 30 of D. leptophallus specimens in order to supplement the existing mounts, and the hooks and eggs were examined in Berlese solution. The staining of the new preparated material were made by Etelka VAJDA in the cestode collection, Hungarian Natural History Museum, Budapest. The drawings and some photographs were made by GEORGIEV on the DIK Microscope (LEITZ) of the Central Helminthological Laboratory, Sofia. The nomenclature of the host is according to HOWARD and MOORE (1980). All measurements are given in mm. RESULTS AND DISCUSSION After reinvestigation of the above-mentioned material, we found that Dilepis yorkei Kotlán, 1923 represents a new genus, Kotlanolepis gen. n. We accept provisionally the genus Mega cirrus Beck, 1951 for further two species: Dilepis leptophallus Kotlán, 1923 and D. horvathi Kotlán, 1923. We present in the following the description of Kotlanolepis gen.n. and the redescriptions of the three species, as well as some remarks about their history of nomenclatural position over the last 65 years. Genus : Kotlanolepis gen. n. Diagnosis: Dilepididae. Scolex massive, not clearly distinguished from the strobila. Rostellum elongate. Rostellar sheath very deep, reaching up to first proglottides of strobila. Rostellar hooks about 50, with characteristic shape, arranged in two rows. Genital pores unilateral. Genital ducts dorsal to excretory canals. Testes four (exceptionally three), situated posteriorly to the primordium of the female genitalia. Cirrus sac highly elongate, reaching almost up to aporal excretory canals in mature proglottides. Cirrus very short and thin, unarmed. Vagina thin-walled, dorsally and posteriorly to cirrus sac. Vitellarium compact, round, situated medially. Ovary consisting of four lobes. Uterus sac-like. Eggs spherical, without filaments. Parasites of Megapodiidae (Galliformes). In papers published in German and in English KOTLÁN used the forename Alexander, equivalent to the Hungarian Sándor.
