Yu, Xiaofei & Yang, Maofa, 2015, Five new species of Ishiharella Dworakowska (Hemiptera: Cicadellidae: Typhlocybinae) with a key to worldwide species of the genus, Zootaxa 4000 (5), pp. 571-580 : 572

Ishiharella dentidensa Yu & Yang , sp. nov.

( Figs 1–9 , 44–45 )

Type material. Holotype: 1 ♂, P. R. China, Mengyang, Yunnan Province, 28 July 2013, coll. Zhihua Fan; 1 ♂, P. R. China, Mt. Leigong, Guizhou Province, 10 July 2011, Zhimin Chang trap (all IEGU).

Length: ♂ 4.14–4.32mm.

Crown orange, with pair of longitudinal pigmented depressions and a yellowish patch. Eyes black; ocelli gray ( Fig. 44 ). Face yellowish, anteclypeus apically black ( Fig. 45 ). Pronotum posteriorly with median triangular black patch ( Fig. 44 ).Scutellum pale orange, scutoscutellar sulcus brownish ( Fig. 44 ). Forewing light brown; hind wing hyaline ( Fig. 44 ). Legs yellowish ( Fig. 45 ).

Male ventral abdominal apodemes reaching posterior margin of segment 3 ( Fig. 1 ). Male pygofer with anterior margin involuted, bearing few setae, ventral margin sinuate, dorsal margin straight; dorsal bridge short ( Figs 3, 4 ). Subgenital plates surpassing pygofer in lateral view, fused in basal 1/3, bearing 10 macrosetae in one row and ca. 42 microsetae in 3–4 rows, width of base nearly equal to width subapically ( Fig. 2 ). Paramere sinuate, subapically broad then narrowing to acute apex, with dorsal process on the swollen subapical part and ventral process near midlength of apophysis ( Figs 5, 6 ). Aedeagus with shaft short, broad, ovoid, strongly laterally compressed, with slender basal apophysis, slightly asymmetrical, branched near apex with branches slightly divergent and with numerous denticuli near apex ( Figs 7, 8 ). Anal tube process sinuate in ventral view, weakly developed ( Fig. 9 ).

Etymology. The new species name is derived from the combination of “denti-”and“densus”, refering to densely denticulate apex of the aedeagal processes.

Remarks. The new species is similar to I. iochoui Dworakowska, 1982 in having a branched aedeagal process ( Figs 7, 8 ) but differs in having many denticuli on the apex of each branch ( Figs 7, 8 ), the paramere with two processes and the apex unbranched and subapically swollen ( Figs 5, 6 ), and the anal tube process sinuate in ventral view ( Fig. 9 ).
