Hu, Shangmi & Xing, Jichun, 2024, Description of two new species of the leafhopper genus Longicornus (Hemiptera: Cicadellidae: Deltocephalinae) from China, Zootaxa 5477 (5), pp. 571-578 : 574-575

Longicornus nonprocessus sp. nov.

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.

Material examined. Holotype: ♂, China: Tibet Autonomous Region., Milin City, Pai Town , 24 August 2020, coll. Yongjin Sui ( GUGC) ; Paratypes: 2♀♀, same data as holotype ( GUGC) .

Remarks. The new species can be distinguished from other species by the aedeagal shaft without process arising basally or apically.

Etymology. The species name is derived from the Latin words “ non- ” and “ processus ”, indicating the aedeagus without process.
