Introduction

The leafhopper genus Pediopsoides (Insecta: Auchenorrhyncha: Membracoidea: Cicadellidae: Macropsinae) was established by Matsumura (1912) for a single species, Pediopsoides formosanus Matsumura, 1912, from Taiwan island of China. In Hamilton’s (1980) Macropsini revision the genus Pediopsoides included 5 subgenera, including the nominate subgenus Pediopsoides (Pediopsoides) for Pediopsoides (Pediopsoides) formosanus Matsumura, 1912 from Taiwan island of China and Pediopsoides (Pediopsoides) satsumensis (Matsumura, 1912) from Kiushu island of Japan. More recently, the following other species have been added: Pediopsoides (Pediopsoides) femorata (Hamilton, 1980) from Taiwan island of China, Pediopsoides (Pediopsoides) kodaiana Viraktamath, 1996 from Tamil Nadu state of India, Pediopsoides (Pediopsoides) jingdongensis Zhang, 2010 from Yunnan Province of China, Pediopsoides (Pediopsoides) bispinata Li, Dai & Li, 2012 and Pediopsoides (Pediopsoides) nigrolabium Li, Dai & Li, 2012 from Guangxi Province of China. Until now there are seven species of the nominate subgenus including five from China.

In the present paper, 2 new species, Pediopsoides (Pediopsoides) damingshanensis Li, Dai & Li sp. n. and Pediopsoides (Pediopsoides) tishetshkini Li, Dai & Li sp. n., from Guangxi province (included in the oriental region) of southern China are described and illustrated, a key to species of the nominate subgenus are provided, along with a map showing the distribution of the new species.

Material and methods

Terminology used in describing the structures follows Hamilton (1980).

External morphology and dissected male genitalia were observed under an Olympus SZ2-ILST stereoscopic microscope and YS 100 microscope. Habitus images of adults were obtained by using a KEYENCE VHX-1000 system and were processed using the software Adobe Photoshop CS6. Hand drawings of the male genitalia were processed with Adobe Illustrator CS6. The body length is measured from the apex of the head to the apex of the forewings and are given in millimeter (mm.).

The type specimens of the new species are all deposited in the Institute of Entomology, Guizhou University, Guiyang, China (GUGC).

Taxonomy

Type species.

Pediopsoides formosanus Matsumura, 1912, by original designation.

Remarks.

The nominate subgenus was characterized by Hamilton (1980) and Li et al. (2012). It can be distinguished by the following combination of features: pronotal striations oblique, forewings with two anteapical cells, dorsal connective freely attached (fused in subgenus Pediopsoides (Celopsis)) to tenth tergite, and male pygofer without multifid or additional spines [male pygofer spine bifid or with rounded lobe on inner margin basally in subgenus Pediopsoides (Sispocnis), a small secondary pygofer spine posteriorly in subgenus Pediopsoides (Nanopsis), and male pygofer spine are multifid in subgenus Pediopsoides (Kiamoncopsis)].

Distribution.

Oriental region: China, Japan and India.

Male genitalia. Pygofer (Fig. 7), with dorsal margin incised, caudal margin truncate, slightly sinuated in lateral view, ventral margin serrate distally with few fine setae. Subgenital plate (Fig. 7), in lateral view, slightly shorter than pygofer, slender, rod-like, with many scattered setae. Style (Fig. 8), slender, apophysis margined with short fine setae, slightly angled after lateral lobe, slightly inflated subapically, apex subacute. Connective (Figs 9–10) distinctly longer than greatest width basally, with anterior medial process long, arms bent dorsally.

Dorsal connective (Fig. 13) “S” shaped with acute apex.
