Abstract

The flea beetle genusLankaphthonaMedvedev, 2001 is redescribed and a new speciesL.yunnantarsellasp. nov.Ruan, Konstantinov & Prathapan is described.LongitarsellaMedvedev, 2009,syn. nov.andPhilotarsaMedvedev, 2009,syn. nov.are newly synonymized withLankaphthona.PhilotarsalaosicaMedvedev, 2009,syn. nov.is synonymized withLankaphthonaphuketensis(Gruev, 1989). The following new combinations are proposed:Lankaphthonabinotata(Baly, 1876),comb. nov.;Lankaphthonacostata(Medvedev, 2016),comb. nov.;Lankaphthonacyanipennis(Medvedev, 2017),comb. nov.;Lankaphthonanigronotata(Jacoby, 1896),comb. nov.;Lankaphthonanotatipennis(Medvedev, 2009),comb. nov.; andLankaphthonaphuketensis(Gruev, 1989),comb. nov., status restored. A highly specialized spoon-shaped ‘appendage’ is discovered on the first abdominal ventrite of males ofLankaphthonabinotata. Aedeagus of the same species has aberrant sheath-shaped phallobase encircling the median lobe. Morphology and possible function of these structures are discussed. Menispermaceae are newly reported as the host plants of the genus.
