Edwardsiana Zachvatkin

Edwardsiana Zachvatkin, 1929: 439.

Type species.

Cicada rosae Linnaeus, 1758, by original designation.

Remarks.

The genus Edwardsiana includes 80 known species worldwide ( Dmitriev 2003), with two species having been reported from China. Here we record three more species from China and provide a key to all Chinese species.

Diagnosis.

Body cream with variable patches (Figs 1-3 ). Crown bluntly produced, medial length shorter than distance between eyes; coronal suture distinct. Pronotum slightly wider than head (Figs 6-8 ). Forewing with apical area short, 1/4-1/3 of total length; RP and MP’ petiolate or not. Hind wing with R and M confluent distally.

Male sternal abdominal apodemes well developed, often extending to middle of 6th sternite.

Male genitalia. Pygofer side often with rounded extension at basal angle; ventral part always with depressed areas, dense stout setae on ventral-basal part and row of short rigid setae caudally. Subgenital plate elongate with subapical part twisted outwards; long macroseta basally and row of short rigid setae from middle to subapex. Paramere with distal part long and curved. Connective with central ridge developed. Aedeagus with preatrium and dorsal apodeme developed; aedeagal shaft with paired apical processes; gonopore apical.
