03EBEF54FFAAFFB00DE237B9FB915749.taxon	diagnosis	Diagnosis. Body robust; crown yellowish marked with dark brown patches. Eyes black, ocelli milk-white. Pronotum with irregular fuscous stripes. Scutellum yellow, with two white spots each bordered by dark brown on the middle of the anterior margin and on both sides. Face with irregular dark brown lateral transverse streaks. Forewing brownish, with scattered hyaline areas. Legs dark, with brownish bands. Head including eyes narrower than pronotum; crown short and weakly produced; face evenly convex in middle; anteclypeus broadened distally. Wing venation without extra costal veins, inner anteapical cell open. Profemur with 2 dorsoapical macrosetae (Ad 1 and Pd 1); row Am reduced to a single stout apical seta (Am 1); intercalary row (Ic) with 15 ~ 17 setae; row Av with several short setae restricted to basal half. Protibia with one macroseta in row Ad and four in row Pd (1 + 4). Metafemur broadened distally and slightly bowed, with the apical setal formula 2 + 2 + 1. Metatibia flattened and nearly straight. Male genitalia. Male pygofer longer than or subequal to height, without any processes, with a few macrosetae distally. Subgenital plate with mesal margin notched preapically; deeply concave near apex; with one row of macrosetae. Style with well-developed subapical lobe, dorsal surface of apophysis sculptured. Connective Yshaped, with stem elongate, about twice as long as arms. Aedeagus with or without dorsal apodeme; shaft more or less tubular, bearing apical, lateral, or basal pair of processes; gonopore apical.	en	Wei, Xingtao, Dai, Wu (2026): A new species of the leafhopper genus Longicornus (Hemiptera: Cicadellidae: Deltocephalinae) from Tibet, China.

03EBEF54FFA8FFB00DE2339BFEF55275.taxon	description	Figs 1 A – H Description. External features as in generic description. Male genitalia. Pygofer side broadly rounded in lateral aspect, with a few irregular macrosetae distally (Fig. D). Valve about 4 times wider than long (Fig. H). Subgenital plate with mesal margin notched preapically, with 6 – 7 macrosetae from middle of the outer margin to apex (Fig. H).

03EBEF54FFA8FFB00DE2339BFEF55275.taxon	discussion	Remarks. The new species is similar to L. longus Xing & Li, 2024 in aedeagal structure, but L. longus has the aedeagal shaft about 2 times as long as the apical processes compared to 1.25 times as long in the new species.	en	Wei, Xingtao, Dai, Wu (2026): A new species of the leafhopper genus Longicornus (Hemiptera: Cicadellidae: Deltocephalinae) from Tibet, China. Zootaxa 5856 (1): 65-69, DOI: 10.11646/zootaxa.5856.1.11, URL: https://doi.org/10.11646/zootaxa.5856.1.11
03EBEF54FFA8FFB00DE2339BFEF55275.taxon	etymology	Etymology. The new species name comes from the Latin “ brevis ”, referring to the short aedeagal shaft compared to that of L. longus.	en	Wei, Xingtao, Dai, Wu (2026): A new species of the leafhopper genus Longicornus (Hemiptera: Cicadellidae: Deltocephalinae) from Tibet, China.
