Abstract

Two new species of the leafhopper subgenus Empoasca (Empoasca) namely, E. (E.) dorsodenticulata Yu & Yang, sp. n. and E. (E.) spiculata Yu & Yang, sp. n. from China are described and illustrated and a key provided for Chinese subgenera of Empoasca.

Highlights

The leafhopper genus Empoasca Walsh, 1862 includes 11 subgenera (Oman et al 1990) of which five occur in China: Empoasca (Empoasca) Walsh, 1862, Empoasca (Distantasca) Dworakowska, 1972, Empoasca (Matsumurasca) Anufriev, 1973, Empoasca (Livasca) Dworakowska & Viraktamath, 1978 and Empoasca (Okubasca) Dworakowska, 1982
Male pygofer lobe with dorsal margin oblique and apical margin straight in lateral view, with fine setae adjacent apical margin; ventral pygofer appendage shorter than pygofer, tapering caudad, subapically denticulate; dorsal bridge about 1/3 length of pygofer (Figs 1, 3, 4)
The new species is similar to Empoasca (Empoasca) borowikae Dworakowska, 1976 but differs in having the male ventral abdominal apodemes reaching segment 4, ventral pygofer appendage denticulate near apex and apical 1/3 of aedeagus with dorsal denticles

Summary

Introduction

The leafhopper genus Empoasca Walsh, 1862 includes 11 subgenera (Oman et al 1990) of which five occur in China: Empoasca (Empoasca) Walsh, 1862, Empoasca (Distantasca) Dworakowska, 1972, Empoasca (Matsumurasca) Anufriev, 1973, Empoasca (Livasca) Dworakowska & Viraktamath, 1978 and Empoasca (Okubasca) Dworakowska, 1982. Body color green to yellowish, with variable symmetrical patches on head and thorax; coronal suture not reaching midlength of crown (Figs 18a, 20a, 24a, 26a); forewing with RP and MP’ stalked (Fig. 22) or separated (Fig. 28), hindwing with CuA unbranched (Fig. 23, 29); male pygofer, with fine sparse setae distally, macrosetae absent, ventral pygofer appendage present (in some species processes crossed in dorsal view), free from pygofer lobe, at least for halflength of pygofer (Figs 1, 9); subgenital plate broad basally, basal series of setae on outer margin and an oblique series of macrosetae from base to apex bi-seriate basally (Figs 5, 13); paramere elongate, curved, with apical teeth (Figs 6, 14); aedeagus with preatrium present, shaft without processes or occasionally with pair of processes, gonopore apical on ventral surface, dorsal apodeme poorly developed or absent (Figs 7, 8, 15, 16); anal tube processes distinct.
