Two new species of the planthopper genus Magadhaideus Long & Chen, 2017 from China, Magadhaideus luchunensis sp. n. and Magadhaideus pingbianensis sp. n., are described and illustrated. Photographs of the new species are provided and a key to species of Magadhaideus is also given.
Achilid, distribution, new species, planthopper, taxonomy
The planthopper tribe Plectoderini (Hemiptera: Achilidae) established by Fennah (Fennah, 1950), containing about 99 genera 346 species, is the largest tribe of Achilidae (Hemiptera: Fulgoromorpha). It is also the most widely disperssed in the world. Plectoderini consists of 13 genera and 26 species (
The genus, so far, includes only two species, M. cervina and M. xiphos, which are only found in China (
The morphological terminology and measurements used in this study follow

1 | Medioventral process of pygofer with apical margin truncate, two lateroapical processes small or slender | 2 |
– | Medioventral process of pygofer with apical margin not truncate, two lateroapical processes large | 3 |
2 | Medioventral process of pygofer with apical margin in the middle distinctly convex; phallobase of aedeagus with outermost left lateral processes with apical 1/2 distinctly bent, directed inwards (Fennah, 1956: fig. 15: D) | M. cervina |
– | Medioventral process of pygofer with apical margin in the middle concave; phallobase of aedeagus with outermost left lateral processes with apical 1/2 hardly bent, directed apically (Figs |

3 | Medioventral process of pygofer with two slender long lateroapical processes (Long et al., 2017: fig.12); phallobase of aedeagus in ventral | M. xiphos |
– | Medioventral process of pygofer with two much smaller and shorter lateroapical processes, not directed outward (Figure |

The salient features of the new species include the following: medioventral process of pygofer with two much smaller lateroapical processes (Fig.

This species is similar to M. xiphos Long & Chen, 2017, but differs from the latter in: medioventral process of pygofer with two small teeth-like lateroapical processes (M. xiphos with two finger-like lateroapical processes); phallobase of aedeagus in ventral view with six processes (M. xiphos with seven processes).
