6422EA44FFD7FF8EFF63D4A1FA8FFCF1.taxon	discussion	Remarks. Idioscopus Baker is similar to Paraidioscopus Maldonado-Capriles in forewing venation, body size and shape of the male pygofer side, subgenital plate and style, but Idioscopus can be distinguished from Paraidioscopus by lateral frontal suture extending to the ocellus, and aedeagal shaft relatively robust and short, usually with two or more pairs of subapical processes, or with one pair but mostly not pointing toward base.	en	Guo, Meishu, Dai, Renhuai (2025): Descriptions of two new species of the leafhopper genus Idioscopus Baker (Hemiptera: Cicadellidae: Eurymelinae: Idiocerini) from China.

6422EA44FFD0FF88FF63D4E9FC2FFDD1.taxon	discussion	Remarks. Based on relevant published articles and examination of some paratypes of I. myrica, we found that I. bimaculatus and I. myrica are essentially identical. Therefore, we consider them synonymous. I. bimaculatus was established by Pruthi in 1936. Pruthi’s description of this species primarily includes the following information: Body yellow. Vertex short, about six times as broad as long in the middle, smooth, medially finely sulcate. Eyes small, chestnut brown. Face pale, convex, slightly longer than broad, frons fairly raised, clypeus large, broader in the apical region; lorae conspicuous; genae comparatively narrow. Ocelli shining and conspicuous; tip of the proboscis marked with black. Pronotum three times the length of the vertex, smooth, without any markings; the anterior and posterior margins slightly convex and concave respectively. Scutellum almost as long as the pronotum, transversely deeply impressed in middle, with a large black round marking near each basal angle. Veins distinct but inconspicuous, only three apical and one ante-apical cells. Aedeagus with one pair of stiff abruptly bent cephalad preapical filaments (Figure 4 F – G). The external morphology and male external genitalia of I. bimaculatus described by Pruthi are basically the same as those described for I. myrica (Figure 4 A – E) by Wang & Dai (2018).	en	Guo, Meishu, Dai, Renhuai (2025): Descriptions of two new species of the leafhopper genus Idioscopus Baker (Hemiptera: Cicadellidae: Eurymelinae: Idiocerini) from China.
