The planthopper genus Trypetimorpha: systematics and phylogenetic relationships (Hemiptera: Fulgoromorpha: Tropiduchidae)

Abstract

The genus Trypetimorpha is revised with the eight currently recognized species described or re-described. Four new species are described and seven new synonymies are proposed. Within Trypetimorphini sensu Fennah (1982), evidences for the monophyly of each genus are selected, but Caffrommatissus is transferred to the Cixiopsini. Monophyly of Trypetimorphini, restricted to Trypetimorpha and Ommatissus, is discussed. A key is given for the following Trypetimorpha species: (1) T. fenestrata Costa (= T. pilosa Horváth, syn. n.); (2) T. biermani Dammerman (= T. biermani Muir, syn. n.; = T. china (Wu), syn. n.; = T. formosana Ishihara, syn. n.); (3) T. japonica Ishihara (= T. koreana Kwon and Lee, syn. n.); (4) T. canopus Linnavuori; (5) T. occidentalis, sp. n. (= T. fenestrata Costa, sensu Horváth); (6) T. aschei, sp. n., from New Guinea; (7) W. wilsoni, sp. n., from Australia; (8) T. sizhengi, sp. n., from China and Viet Nam. Study of the type specimens of T. fenestrata Costa shows that they are different from T. fenestrata sensu Horváth as usually accepted, which one is redescribed here as T. occidentalis.
