Two new genera and two new species of Delphacidae (Hemiptera: Fulgoroidea) from China

Abstract

Two new genera, Ramidelphax and Consociata, from southern China, are pr oposed within Delphacidae, based on th e new species Ramidelphax albistriata n. sp. (from Hainan and Guizhou Provinces, China ) and Consociata sinensis n. sp. (from Haina n Province, China). Because o f the presence of the post-tibal spur, the new genera should be place d in the tribe Delphacini.

First report of the invasive crop pest Stenocranus pacificus (Hemiptera: Delphacidae) in temperate Asia

“…southern Zhejiang, mainland China, and Okinawa Island, Ryukyu Archipelago, Japan) (Qin et al . 2010; Fujinuma & Hayashi 2015). Stenocranus pacificus is a serious pest of corn in these Southeast Asian countries, where their extended feeding activity leads to chlorosis and leaf necrosis, reduced plant vigor, and stunting, and their excreted honeydew leads to the growth of sooty molds that can reduce photosynthesis in plants, causing hopperburn (Dumayo et al .…”

“…pacificus has been recorded in Zhejiang Province, China (Qin et al . 2010), a region from which planthoppers are known to migrate to Japan (Sogawa 1994). Alternatively, S .…”

Three new species of the bamboo-feeding planthopper genus Bambusiphaga Huang & Ding from China (Hemiptera: Fulgoroidea: Delphacidae)

“…It belongs to the tribe Tropidocephalini within the subfamily Delphacinae (Hemiptera: Fulgoroidea: Delphacidae). Until now, 28 species of this genus were known from Oriental region, viz, China (25 species), Philippines (1 species), Singapore (2 species), Malaysia (2 species), North-Eastern Himalayas (1 species), and India (1 species) (Yang & Chen 2011;Qin et al 2012;Li et al 2018;Ramya & Meshram 2019). Bambusiphaga can be recognized by the following characters: body yellowish-brown, often with brown or black markings; head including eyes narrower than pronotum; mesonotum longer at middle line than vertex and pronotum together; aedeagus (phallotheca) complex, tubular, with or without phyllobase; and segment 10 ring-like, with or without process.…”

Parasogata gen. n., a new genus of the tribe Delphacini with descriptions of two new species from China (Hemiptera, Fulgoromorpha, Delphacidae)

“…The planthopper tribe Delphacini Leach, 1815 is the largest clade of Delphacidae, occurring in all ecoregions (excluding Antarctica) and including approximately 1652 species in 319 genera (Bourgoin 2018). In China, 259 species in 135 genera are known (Ding 2006; Dong and Qin 2012; Hou et al 2013, 2014a, b; Qin 2005, 2006, 2007; Qin et al 2006, 2008, 2009a, b, 2010, 2011, 2012, 2014; Ren et al 2015).…”
