C33D1176FFFDFFD8FF60F98ED97CF882.taxon	discussion	Remarks. The new species is similar to L. furcatus Fang & Xing, 2018, but can be distinguished from the latter by the long branches of the aedeagal processes approximately subtriangular, thin, and its outer margin with fine teeth; valve strip-shaped and posterior margin concave.	en	Hu, Shangmi, Xing, Jichun (2024): Description of two new species of the leafhopper genus Longicornus (Hemiptera: Cicadellidae: Deltocephalinae) from China.

C33D1176FFFDFFD8FF60F98ED97CF882.taxon	etymology	Etymology. The species name is derived from the Latin word “ concavus ”, indicating the valve with posterior margin concave.	en	Hu, Shangmi, Xing, Jichun (2024): Description of two new species of the leafhopper genus Longicornus (Hemiptera: Cicadellidae: Deltocephalinae) from China.

C33D1176FFFFFFDEFF60F8B8D963F8EB.taxon	description	Figs 11 – 20 Description. General appearance as in Longicornus concavus sp. nov., but scutellum with bright spots. Male genitalia. Pygofer side elongate, base wide, apex narrow, with numerous macrosetae on posterior area (Fig. 15). Subgenital plate with 8 setae along lateral margin (Fig. 16). Aedeagus without process, short and stout with base broad in lateral view, gradually tapered to apex in lateral view; gonopore apical (Figs. 17 – 19). Connective stem apex expanded, subquadrate; with anterior arms nearly 1 / 3 length of stem (Figs. 17 – 19). Female seventh sternite approximately as long as broad at base, caudal margin medially produced (Fig. 22). Female pygofer with ventroposterior margin slightly incurved. (Fig. 21). First valvulae with obscure reticulate sculpture dorsally and scale-like sculpture ventrally (Figs. 23, 24). Second valvulae with some distal teeth occupying about half of the total length (Figs. 25, 26). Measurement. Length (including tegmen): ♂, 5.6 mm; ♀, 5.7 – 6.0 mm.	en	Hu, Shangmi, Xing, Jichun (2024): Description of two new species of the leafhopper genus Longicornus (Hemiptera: Cicadellidae: Deltocephalinae) from China.
