Nabalua

Abstract: The genus Maua was erected by Distant (1905) for Cicada quadrituberculata Signoret, 1847 and M. affinis Distant, 1905. The genus is currently placed in the tribe Dundubiini and the subtribe Leptopsaltriina (Duffels & Van der Laan 1985; Moulds 2005). In 1923, Moulton erected the new section Leptopsaltraria [sic] for the genera Leptopsaltria Stal, 1866, Maua Distant, 1905, Nabalua Moulton, 1923, Purana Stal, 1866 and Tanna Distant, 1905. The new section was characterised by the presence of one to three pairs of tubercles on the ventral side of the male abdomen. A revision of Nabalua was recently presented by Duffels (2004), and three, presumed monophyletic, groups of the genus Purana were revised: the P. nebulilinea group (Kos & Gogala 2000), the P. carmente group (Schouten & Duffels 2002) and the P. tigrina group (Duffels et al. 2007). In 1963, Metcalf added several genera, with and without abdominal tubercles, to the subtribe; none of these genera are recorded from Sundaland. This paper presents a revision of the genus Maua from Sundaland: the Malay Peninsula, Java, Sumatra, Borneo, Palawan and several smaller islands inbetween. Two species of Maua, M. borneensis from Borneo and M. palawanensis from Palawan and Balabac are described as new to science, and six species from Sundaland are redescribed: M affinis, M. albigutta (Walker, 1857), M. latilinea (Walker, 1868), M. linggana Moulton, 1923, M. platygaster Ashton, 1912, and M. quadrituberculata. Two species, M. ackermanni Schmidt, 1924 and M. dohrni Schmidt, 1912, both described from Sumatra, proved to be junior synonyms of respectively M. quadrituberculata and M. latilinea. Three species of Mau are not treated in this paper: M. albistigma (Walker, 1850) and M. fukienensis Liu, 1940 from China, and M. philippinensis Schmidt, 1924 from the Philippines. This study aims to contribute to a better knowledge of cicada biodiversity in Southeast Asia. Basic systematic studies providing illustrations and descriptions of species and keys to genera and species are regarded as a prerequisite for biodiversity studies. Biodiversity studies of cicadas in other tropical areas, such as Sulawesi, New Guinea, and the West Pacific, A revision of the cicadas of the genus Maua Distant (Hemiptera, Cicadidae) from Sundaland

Abstract: This revision of Nabalua contains a description for the genus and descriptions, illustrations and distribution maps for the six species attributed to the genus. N. mascula and N. neglecta, both from Borneo (Sabah), are redescribed, and four species are described as new to science: N. borneensis from Borneo (Sabah and Sarawak), N. maculata from Borneo (Sarawak), N. sumatrana from Sumatra, and N. zaidii from Malayan Peninsula. Nabalua is supposed to be monophyletic. A key for the identification of the males of the genus is provided.
