Pediopsis Burmeister

Li, Hu, Dai, Ran-Huai & Webb, Michael D., 2023, Description of two new species of the leafhopper genus Pediopsis Burmeister (Hemiptera, Cicadellidae, Eurymelinae, Macropsini) from China, ZooKeys 1149, pp. 135-144 : 135

Genus Pediopsis Burmeister

Bythoscopus (Pediopsis) Burmeister, 1838: 11.

Pediopsis - Kirkaldy 1903: 214; Hamilton 1980: 902.

Type species.

Jassus tiliae Germar, 1831, by subsequent designation of Kirkaldy (1903).

Distribution.

Palaearctic, Oriental, Nearctic, and Australian regions.

Remarks.

Pediopsis can be distinguished by the following combination of features: head across eyes usually distinctly narrower than pronotum, face wider than long, lora relatively large, pronotum frontally declivous and usually with strongly oblique striations, male pygofer without spines or processes, dorsal connective usually strongly developed. The traditional separation of Pediopsis from Pedionis ( Hamilton 1980) is followed here, but, as more species become known, the two genera may be synonymized. The difficulty in defining Pediopsis is apparent from the fact that the genus was keyed out in two places in Hamilton’s (1980) key. At present, the most reliable feature to separate the two genera is the presence or absence of processes or spines on the ventral margin of the male pygofer (absent in Pediopsis and present in Pedionis ).
