Magadhaideus, a new genus of the tribe Plectoderini with the description of a new species from China (Hemiptera, Fulgoromorpha, Achilidae)

Abstract

A new planthopper genus and species from China, Magadhaideus xiphos Long & Chen, gen. et sp. n. (Hemiptera: Fulgoromorpha: Achilidae: Plectoderini), is described and illustrated. A new combination, Magadhaideus cervina (Fennah, 1956), comb. n. transferred from Magadha Distant and a key to species of the new genus are also given.

Two new species of genus Magadhaideus Long & Chen, 2017 from China (Hemiptera: Fulgoromorpha: Achilidae)

“…The planthopper genus Magadhaideus (Achilidae: Plectoderini) was established by Long and Chen (2017) with Magadhaideusxiphos Long & Chen, 2017 from China as the type species. Magadhaideus is similar to Magadha in mesonotum bearing a transverse callus on anterior third of disc (readily distinguished from other known genera in the tribe Plectoderini), but differs from Magadha in the characteristics of pygofer, medioventral process and phallobase (Long et al 2017). …”

“…The standard terminology for hind and forewing venation follow Bourgoin et al (2015). The methods follow Long et al (2017). Body length was measured from apex of vertex to tip of forewing; vertex length was measured the median length of vertex (from apical transverse carina to tip of basal emargination).…”

“…Genus diagnostic characters mainly follow Long et al (2017). Mesonotum with a transverse callus on anterior third of disc (Figs 5, 26; Long et al 2017: fig.…”

“…Mesonotum with a transverse callus on anterior third of disc (Figs 5, 26; Long et al 2017: fig. 5); pygofer in lateral view with dorsal margin distinctly shorter than ventral margin (Figs 11, 32; Long et al 2017: fig.…”

“…The genus, so far, includes only two species, M.cervina and M.xiphos , which are only found in China (Fennah 1956; Long et al 2017). In this paper, the specimens of Magadhaideus , depositing in the Institute of Entomology, Guizhou University, Guiyang, China, were re-examined, and yielded a further two new species from Yunnan, China.…”
