Yao, Binbin, Dietrich, Christopher H. & Xing, Jichun, 2022, Description of a new species of the leafhopper genus Tambocerus (Hemiptera: Cicadellidae: Deltocephalinae) from Guizhou, China, Zootaxa 5169 (1), pp. 87-92 : 89-90

Tambocerus fanjingensis sp. nov.

( Figs 1–12 )

Description. Color pattern typical for genus.Vertex with median length 0.35x basal width between eyes. Head in dorsal view slightly narrower than pronotum. Fore femur with one dorsoapical seta, row AM with 2 stout setae, and row IC with 3 stout setae and several short setae. Hind femur setal formula 2+2+1. Hind tibia row PD with 21 macrosetae; row AD with approximately 13 long stout setae and 0–4 short and stout setae between each long seta.

Male genitalia. Pygofer elongate, triangularly produced into straight spinelike process posteriorly, with scattered fine setae ( Figs 5, 6 ). Valve triangular ( Fig. 7 ). Subgenital plate abruptly narrowing at midlength, apical half slender with three stout macrosetae and several short setae ( Fig. 8 ). Aedeagal shaft in ventral view broad, 1/3 as wide as long in ventral view, lateral margins with serrations ( Fig. 9 ); aedeagus in lateral view strongly curved dorsally, Cshaped, apex expanded with a small triangular lamellar process in lateral view ( Fig. 10 ); gonopore apical ( Figs 9, 10 ). Connective stem twice as long as arms ( Fig. 11 ). Style broad at base, abruptly narrowing subapically, preapical lobe with setae ( Fig. 12 ).

Measurement. Length (including tegmen): ♂, 6.6–6.8 mm.

Host plant. Grasses.

Type material. Holotype: ♂, CHINA: Guizhou Prov., Jiangkou County, Mt. Fanjing , 30 May 2021, coll. Binbin Yao ( GUGC) . Paratypes: 2♂♂, same data as holotype ( GUGC) .

Remarks. The new species is similar to T. robustispinus Qu & Dai, 2014 , but can be distinguished from the later by the relatively broad, parallel-sided aedeagal shaft in posterior view with the lateral margins serrate throughout their length and the apex lacking distinct processes.

Etymology. This new species is named after its type locality “Fanjing”.
