INTRODUCTION The Rossel Island, called as well Yela, is a small island in the Pacific Ocean not longer than 37 km and 16 km wide. It belongs to the Louisiade archipelago (Papua New Guinea) and stretches out to 370 km southeast from the New Guinea’s coastline. Actually, 45 genera are described for the Lophopidae, 5 of which are fossils (Bourgoin 2016). Eight genera are present on the New Guinea island: Lophops Spinola, 1839, which is a cosmopolitan genus and Kasserota Distant, 1906, Megacarna Baker, 1925, Zophiuma Fennah, 1955, Maana Soulier-Perkins, 1998, Jugoda Melichar, 1915, Acarna Stål, 1863 and Onycta Fennah, 1955 that are restricted to New Guinea and to several small closely located islands. Phylogenetic analyses showed that four main lineages can be recognized, Carriona + group with its only representative Carriona Muir, 1931, Makota + , Sarebasa + and Bisma + (Soulier-Per- kins 2001). According to Emeljanov (2013), the genus should be placed within the Menoscinae. However, the placement of the new genus, described here, is given at minima only to family level as we expect it should be a monophyletic lineage for the reason advocated in Wang et al. (2016a). In order to place the new genus described here correctly, a new phylogeny of the fami- ly should be undertaken but for now, from many Asian countries and Austral-Asian islands, many genera and species of the family have to be described first, as shown for China in Wang et al. (2016b). MATERIAL AND METHODS Preparation and observation The abdomen of the specimen examined was cut off and cleared for 10 minutes in warm (50°C) 10% KOH. Dissections and cleaning of genital structures were performed in distilled water. Final observations were made in glycerin using Olympus stereomicroscope (SZH10). The photos of the habitus were taken using a stereomicroscope Leica MZ 16 with IC3D digital cam- era; final images were produced using Helicon Focus 5.0 software. The SEM photographs of uncoated speci- men were taken in the Laboratory of Scanning Micro- scopy, MIZ PAS (Warsaw), using a scanning micro- scope HITACHI S-3400N under Low Vacuum conditions.

The species is described from a single male specimen. The genus is placed as incertae sedis in the Lophopidae. ｱ Key words.— Papua New Guinea, new species ANNALES ZOOLOGICI (Warszawa), 2016, 66(2): 213-225 PL ISSN 0003-4541 © Museum and Institute of Zoology PAS doi: 10.3161/00034541ANZ2016.66.2.005
