New tribe, new genera, and new species of the family Issidae (Hemiptera: Fulgoroidea) from Southeastern Asia and New Guinea, with notes on morphology and evolution of the family

Abstract

Eupilisini trib. nov. is erected for the genera Eupilis Walker, 1857, Gabaloeca Walker, 1870, Syrgis Stål 1870, and Bornepilis gen. nov. (type species: Bornepilis longipennis sp. nov.) in the subfamily Issinae of the family Issidae. Bornepilis longipennis sp. nov. is described from Sabah State of Malaysia in northern Borneo. Two new species of the genus Eupilis are described from northwestern Borneo – E. borneoensis sp. nov. and E. walkeri sp. nov. Eupilis hyalinocosta Melichar, 1914 is redescribed and together with E. rubrovenosa Melichar, 1914 is transferred to Bornepilis gen. nov. Eupilis albilineola Walker, 1857, E. hebes Walker, 1857, and Gabaloeca retifera Walker, 1870 are redescribed. Eupilis nigrinervis Stål, 1870 is redescribed and transferred to the genus Gabaloeca. Three new combinations are formed: Bornepilis hyalinocosta (Melichar, 1914), comb. nov., B. rubrovenosa (Melichar, 1914), comb. nov., and Gabaloeca nigrinervis (Stål, 1870), comb. nov. Paguinella ramosa gen. et sp. nov. is described from the canopies of Madang Province in Papua New Guinea. This new genus is closely related to New Guinean genus Papunega Gnezdilov et Bourgoin, 2015, but well distinguished by ventral aedeagal hooks each with two long branches and wide neck of capitulum of style. Morphology of hind wing and male genitalia of the members of issid tribes Eupilisini trib. nov., Issini, Sarimini, Chimetopini, and Kodaianellini are discussed and illustrated in accordance to evolution and historic distribution of the family Issidae from southeastern Asia to America and tropical Africa. New data on distribution of Bornepilis hyalinocosta and Gabaloeca nigrinervis in the Philippines are given.
