A new tribe of Elicinae Melichar, 1915 (Hemiptera, Tropiduchidae) with the description of a new genus and two new species from southern China

A new tribe, Elibucini trib. nov., is established in the subfamily Elicinae Melichar, 1915 (Hemiptera, Tropiduchidae) to accommodate the new genus Elibuca Zhou & Chang, gen. nov. The tribe is diagnosed by a distinctive combination of characters, including steeply tectiform forewings with well-developed nodal and subapical lines, hind tibiae lacking lateral spines, an elongate phallobase reaching or approaching the apex of the aedeagus, and rounded gonoplacs lacking marginal teeth.

Two new species are described from southern China, and illustrated: Elibuca clavata Zhou & Chang, sp. nov. from Hainan, designated as the type species, and E. lobata Zhou & Chang, sp. nov. (Guizhou and Sichuan). Keys to the tribes of Elicinae and to the species of Elibuca are provided.
