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

Abstract

A new delphacid genus and species, Lauriana senticosa Ren & Qin, gen. et sp. nov. (Hemiptera: Delphacidae: Tropidocephalini) is described from Sichuan, China. Habitus photos and illustrations of male genitalia of the new species are given, and the differences between the new genus and its closely related genera are discussed.

Resolving phylogenetic relationships of Delphacini and Tropidocephalini (Hemiptera: Delphacidae: Delphacinae) as inferred from four genetic loci

“…In Tropidocephalini, the genus Lauriana Ren & Qin grouped with Malaxa Melichar, and thence to a clade contained Malaxella Ding & Hu, supporting the previous morphological studies of Ren et al . 29 . Belocera and Arcofacies are closely related and in accordance with the study of Yang 23 .…”

“…The tribe currently contains more than 180 species in 37 genera widely distributed throughout the Palaearctic, Afrotropical, Indomalayan, Australian, Neotropical and Pacific Regions, but most diverse in the Indomalayan Region 29–31 . The Tropidocephalini primarily feed on bamboos, with a few species feeding on other grasses 30, 31 .…”

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

“…Malaxa falls within the tribe Tropidocephalini in the subfamily Delphacinae. The Tropidocephalini consists of approximately 35 genera and 179 species widely distributed throughout the Palaearctic, Afrotropical, Indomalayan, Australian, Neotropical, and Pacific Regions, but is most diverse in the Indomalayan Region , Ren et al 2014, Huang et al 2017, Bourgoin 2017. New World Tropidocephalini was reviewed by Bartlett (2009) including a key to genus and a review of reported plant associations.…”

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

“…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).…”

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. Fennah (1956) established the genus Arcofaciella Fennah, 1956 with two species: A. verrucosa Fennah, 1956 (as its type species) from Hong Kong, China, and A. penangensis (Muir, 1919) (previously placed in the genus Acrofacies Muir, 1915by Muir 1919 from Penang, Malay Peninsula.…”
