Revision of the genus Symplana Kirby, 1891 (Hemiptera: Fulgoromorpha: Caliscelidae), with notes on genitalic morphology of Augilini and description of three new species from Vietnam and Sumatra

Abstract

The caliscelid genus Symplana Kirby, 1891 is revised, with the type species, S. viridinervis Kirby, 1891, is redescribed based on the lectotype. Three new species are described: Symplana maurici sp. n. and S. vieta sp. n. – from northwestern and central Vietnam and S. sultana sp. n. – from eastern Sumatra. Symplana elongata Meng, Qin et Wang, 2020 is placed in synonymy under S. brevistrata Chou, Yuan et Wang, 1994. Key to species of the genus is given. Peculiarities of connective structure and its connection with an aedeagus as well as fusion of endogonocoxal lobes in ovipositor are discussed and illustrated for different Augilini taxa and compared with other Caliscelidae.
