A key to the genera of Tropidocephalini (Hemiptera: Fulgoromorpha: Delphacidae) of China with description of Mucillnata rava, new genus and species

Abstract

A new planthopper genus, Mucillnata, is established with a new species, Mucillnata rava sp. nov. as the type species, in the tribe Tropidocephalini, subfamily Delphacinae from southern China. A key to the known genera of the tribe from China is also provided and the differences between the new genus and closely related genera are discussed.

A review of New World Malaxa (Hemiptera: Fulgoroidea: Delphacidae)

“…Most Tropidocephalini with reported plant associations feed on bamboo (reported as 78% by Wilson et al 1994), with all the remaining associated with other grasses (e.g., Wilson et al 1994, Chen 2003, Qin & Zhang 2010. Exceptions to bamboo feeding include species of Tropidocephala Stål on Andropogon L. (e.g., Nickel 2003), Jassidaeus lugubris (Signoret) on Festuca L. (Asche & Hoch 1982, Wilson et al 1994, and interestingly, Columbisoga Muir (3 species), Macrocorupha gynerii Muir, and Malaxa occidentalis Muir (from the New World) on Gynerium P. Beauvois (Poaceae: Panicoideae: Gynerieae; e.g., Soreng et al 2015).…”

Review the bamboo-feeding genus Arcofaciella Fennah, 1956 (Hemiptera: Fulgoromorpha: Delphacidae) with description of a new species from India

“…In China, 115 species in 23 genera are known, representing the richest species diversity of this tribe worldwide (Chen 2003;Ding 2006;Qin & Zhang 2010;Hu & Ding 2013;Ren et al 2014;Li et al 2020). Most Tropidocephalini with reported plant associations feed on bamboo, with all the remaining associated with other grasses (Wilson et al 1994;Chen 2003;Chen & Tsai 2009;Qin & Zhang 2010;Bartlett & Kennedy 2018). Ren et al (2014) estimated that many species of the tribe remained undescribed, an interpretation supported by the ongoing descriptions of new endemic species in recent years (Li et al 2018(Li et al , 2019a(Li et al , 2019b(Li et al , 2019c(Li et al , 2020.…”

“…The planthopper tribe Tropidocephalini Muir, 1915 is the second largest clade of Delphacidae Leach, 1815, mainly occurring in the Oriental region and including approximately 192 species in 37 genera (Chen & Tsai 2009;Bourgoin 2020). In China, 115 species in 23 genera are known, representing the richest species diversity of this tribe worldwide (Chen 2003;Ding 2006;Qin & Zhang 2010;Hu & Ding 2013;Ren et al 2014;Li et al 2020). Most Tropidocephalini with reported plant associations feed on bamboo, with all the remaining associated with other grasses (Wilson et al 1994;Chen 2003;Chen & Tsai 2009;Qin & Zhang 2010;Bartlett & Kennedy 2018).…”

Lauriana Ren & Qin, a new genus of the tribe Tropidocephalini (Hemiptera: Fulgoromorpha: Delphacidae) from China

“…Tropidocephalini is the second largest tribe of the delphacid subfamily Delphacinae (Hemiptera: Fulgoroidea: Delphacidae), currently containing more than 180 species in 36 genera (Chen & Tsai 2009;Bartlett 2009;Qin & Zhang 2010;Hu & Ding 2013). Species of the tribe are widely distributed throughout the Palaearctic, Afrotropical, Oriental, Australian and Pacific Regions, but most species, feeding on bamboos, are recorded from the Oriental Region (Chen & Tsai 2009).…”

“…The Chinese fauna of Tropidocephalini, comprising about 90 described species in 22 genera, represents the richest species diversity of this tribe worldwide, with most taxa restricted to south China (Chen 2003, Ding 2006, Qin & Zhang 2010. However, many species remain unknown and await descriptions.…”
