FOLIA ENTOMOLOGICA HUNGARICA ROVARTANI KÖZLEMÉNYEK Volume 63 2002 pp. 17-22. Description of a new horned jumping spider species Thorelliola mahunkai (Araneae: Salticidae) from New Guinea T. SZŰTS Abstract: A horned jumping spider species, Thorelliola mahunkai sp. n. is described from New Guinea. The type species of the genus is also illustrated. Key words: Salticidae, Thorelliola, new species, Papua New Guinea INTRODUCTION The genus Thorelliola was established by Strand in 1942 for Thorellia ensifera (the previous name of the genus - Thorellia Keyserling, 1882 was preoccupied). The genus contains now eight nominal species, mainly described by Berry et al. (1997) and Gardzinska & Patoleta (1997). During cataloguing the jumping spider collection of the Hungarian Natural History Museum, I found a few tubes identified by Kálmán Szombathy, labelled as Thorellia, and several indet., in the Balogh collection. This peculiar genus is easy to recognise, as the males have "horns" on the clypeus. The specimens definitely belong to the genus Thorelliola, but do not correspond with any hitherto known species. MATERIALS AND METHODS The specimens were examined by methods set in Wanless 1978. The drawings were made with camera lucida, all the measurements are given in millimetres. The photographs were made by Nikon Coolpix digital camera, attached to the stereomicroscope. The specimens are deposited in the Soil Zoological Collection (former Arachnoidea Collection) of the Hungarian Natural History Museum, Budapest (curator Sándor Mahunka). Abbreviations: AEW: anterior eye width, AME: anterior median eye, hl—II: central setae on the clypeus - composing the horn, PEW: posterior eye width, PLE: posterior lateral eye, sI-IV: lateral setae on the clypeus.
