Two new genera and two new species of Oriental dictyopharid planthoppers (Hemiptera: Fulgoromorpha: Dictyopharidae) from Sri Lanka and southern India

摘要

Two new Oriental dictyopharid genera are described from Sri Lanka and southern India, respectively. Truncatomeria gen. nov. is established based on a single known species from Sri Lanka. Its type species, Dictyophora [sic] viridistigma Kirby, 1891 wasfirst described in Dictyophara and then assigned to Centromeria Stal by Distant (1906). However, it bears many different characters from other Centromeria species and should be transferred to a new genus. The second new genus, Paradictyopharina gen. nov. is established for two new species, P. parallela sp. nov. and P. spina sp. nov., both from southem India. The new genus is externally similar to Dictyopharina Melichar, but can be distinguished from the latter by the differences of its mesonotum, forefemora, hind tibiae and aedeagus. Photographs of the adults of all species are presented. Descriptions of the two genera and their included species are provided together with structural illustrations.
