A key to species of the leafhopper genus Tambocerus (Hemiptera, Cicadellidae, Deltocephalinae) with description of a new species from Pakistan Author Naveed, Hassan Author Zhang, Yalin text Zootaxa 2018 2018-08-27 4462 2 237 244 journal article 29401 10.11646/zootaxa.4462.2.5 7cb29624-842c-4c50-8c8c-9c0df17dc878 1175-5326 1441561 C91A5E57-9933-4EF7-AD9B-046CFD8BA9F2 Tambocerus bulbulus sp. nov. Figs. 3A–D , 4A–I Description. Pale yellow ( Figs. 3A–C ). Head with a pair of brown spots on anterior and posterior margin of vertex, posterior one rather small ( Fig. 3A ). Vertex with transverse dark brown band anteriorly. Pronotum rather brownish yellow with minute fuscous brown spots. Tegmina ending with few brown spots, veins pale ( Figs. 3A, C ). Face brownish yellow with fuscous brownish transverse bands interrupted medially following a dorsal dark brown transverse band ( Fig. 3B ). Head about as wide as or slightly narrower than pronotum. Vertex nearly 2.7x as wide between eyes as median length. Anteclypeus broadened apically ( Fig. 3B ). Scutellum with median transverse ridge slightly curved posteriorly ( Fig. 3A ). Fore tibia with dorsal setal formula 5+5. Macropterous. Forewings extending beyond the apex of abdomen. Genitalia. Male pygofer in lateral view broad at base, lateral margins narrowing posteriorly with dorsal marginal thickening in posterior half, posteroventral margin with dark pigmented crest; lacking macrosetae ( Figs. 4A–B ). Subgenital plates bulging and subtriangular with apical 1/4 length membranous, not prolonged, with few uniseriate macrosetae laterally just before apical membranous region ( Fig. 4F ). Style with preapical lobe short, apophysis moderately thick, digitate ( Figs. 4C–D ). Connective with stem approximately twice as long as arms ( Fig. 4G ). Aedeagal shaft with lateral lamellate projection serrate on apical half, shaft dorsally curved, strongly constricted before apex to form a neck in ventral view with asymmetrical serrations ( Figs. 4H–I ). Female seventh sternite nearly 2.5 times as wide as median length, median projection posteriorly rounded with dark pigmentation ( Fig. 3D ). Type material. Holotype : ♂ , Pakistan , Khyber Pakhtunkhwa Province , Abbottabad City , 1250m , 4-VIII-2016 , coll. Hassan Naveed . Paratypes : 1♂ , 1♀ , same data as holotype . Diagnosis. This resembles T . viraktamathi Rao but differs in the following characteristics: lacking brown irroration on the forewings, male pygofer narrower distally in lateral view, posterior margin with ventral serrated area longer and closer to dorsal sclerotized area, lobes more curved with apices more acute in dorsal view; subgenital plates with apical finger-like extensions longer. Etymology. The species epithet is derived from the Latin word bulbulus referring to the subgenital plates having a rounded triangular shape.
