Ishiharella dentidensa Yu & Yang  , sp. nov.

( Figs 1–9View FIGURES 1 – 9, 44– 45View FIGURES 44 – 53)

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. 44View FIGURES 44 – 53). Face yellowish, anteclypeus apically black ( Fig. 45View FIGURES 44 – 53). Pronotum posteriorly with median triangular black patch ( Fig. 44View FIGURES 44 – 53).Scutellum pale orange, scutoscutellar sulcus brownish ( Fig. 44View FIGURES 44 – 53). Forewing light brown; hind wing hyaline ( Fig. 44View FIGURES 44 – 53). Legs yellowish ( Fig. 45View FIGURES 44 – 53).

Male ventral abdominal apodemes reaching posterior margin of segment 3 ( Fig. 1View FIGURES 1 – 9). Male pygofer with anterior margin involuted, bearing few setae, ventral margin sinuate, dorsal margin straight; dorsal bridge short ( Figs 3, 4View FIGURES 1 – 9). 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. 2View FIGURES 1 – 9). 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, 6View FIGURES 1 – 9). 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, 8View FIGURES 1 – 9). Anal tube process sinuate in ventral view, weakly developed ( Fig. 9View FIGURES 1 – 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, 8View FIGURES 1 – 9) but differs in having many denticuli on the apex of each branch ( Figs 7, 8View FIGURES 1 – 9), the paramere with two processes and the apex unbranched and subapically swollen ( Figs 5, 6View FIGURES 1 – 9), and the anal tube process sinuate in ventral view ( Fig. 9View FIGURES 1 – 9).
