FOLIA ENTOMOLOGICA HUNGARICA ROVARTANI KÖZLEMÉNYEK Volume 64 2003 pp. 41-57. On remarkable jumping spiders (Araneae: Salticidae) from Papua New Guinea T.SZŰTS Abstract: Jumping spiders with a remarkable, unique carapace shape are discussed. The genera Leptathamas Balogh, 1980 and Furculattus Balogh, 1980 are redescribed and illustrated, and the unknown male of Leptathamas paradoxus Balogh, 1980 is described for the first time. Comparison is made to other genera with four eye rows [Leptathamas Balogh, 1980, Athamas O. P. - Cambridge, 1877 and Bulolia Zabka, 1996), as they may be related. Athamas debakkeri sp. n. is described from New Ireland. New distributional data of the taxa mentioned are presented. With 24 original drawings and 14 photos. Key words: Furculattus, Leptathamas, Athamas, Bulolia, new species, redescriptions INTRODUCTION Péter Balogh described many new jumping spiders (Salticidae) from Papua New Guinea at the early '80s (Balogh 1979, 1980a, b, c, 198k/, b). Having been deposited in the so-called "Balogh Collection, Budapest" (Balogh 1980a, /?), type specimens of these taxa were for a long time inaccessible to other specialists for scientific study. However, recently this material became part of the Soil Zoological Collections of the Hungarian Natural History Museum, Budapest. In preparing a catalogue of this collection, I found the types of the monotypic genera Furculattus Balogh, 1980 and Leptathamas Balogh, 1980, with some other specimens, that belong to these taxa. This included a female of Furculattus, which is described and figured as female of Diolenius minotaurus (Wanless et Lubin, 1986) and the unknown male of Leptathamas Balogh, 1980. These genera are unique salticids, because their remarkable carapace features. They need to be redescribed, because the original descriptions by Balogh were based only on one sex each. Leptathamas seems to be a close relative of the genera Athamas O. P. - Cambridge, 1877 and Bulolia Zabka, 1996, occupying a "midway" position between them. During the study a new Athamas species, A.
