Abstract

A new species of Eudeferunda Chen, Yang & Wilson, 1989 (Hemiptera: Fulgoromorpha: Achilidae: Plectoderini), Eudeferunda alatea Long & Chen sp. n. from Hainan, China, is described and illustrated. The generic characters are modified, including the addition of male genitalia characters. A key to the species of the genus is provided.

Highlights

The achilid genus Eudeferunda (Hemiptera: Fulgoromorpha: Achilidae: Plectoderini) was established by Chen et al (1989), and with E. lenita Chen, Yang & Wilson, 1989 as its type species
Male genitalia with phallobase submembraneous, tube-like, phallobase with dorsal and ventral lobes; ventral lobe of phallobase in ventral view cleft at apical margin in middle, each lateral side with a pointed processes, bilateral areas with thorns; in dorsal view, dorsal lobe of phallobase with apical margin broadly incised in middle; phallic appendages longer than phallobase about 3:1, gradually narrowing apically (Figs 17–18, 27–28)
Male genitalia with phallobase in ventral view (Fig. 17), ventral lobe cleft at apical margin in middle, bilateral areas hump-shaped and protuberated subapically, a pointedly alate process at base 1/3 of each lateral side, with its base of inside margin denticulated and apically extended; in dorsal view (Fig. 18), dorsal lobe with apical margin broadly incised in middle, bilateral margin ox-horn like produced

Summary

Introduction

The achilid genus Eudeferunda (Hemiptera: Fulgoromorpha: Achilidae: Plectoderini) was established by Chen et al (1989), and with E. lenita Chen, Yang & Wilson, 1989 as its type species. Longer than vertex and pronotum together, lateral carinae slightly diverging posteriorly, middle carina apically obsolete (Figs 7, 19). Male genitalia with phallobase submembraneous, tube-like, phallobase with dorsal and ventral lobes; ventral lobe of phallobase in ventral view cleft at apical margin in middle, each lateral side with a pointed processes, bilateral areas with thorns; in dorsal view, dorsal lobe of phallobase with apical margin broadly incised in middle; phallic appendages longer than phallobase about 3:1, gradually narrowing apically (Figs 17–18, 27–28).
