Ishiharella falcata Yu, Yang & Dietrich  , sp. nov.

( Figs 10–18View FIGURES 10 – 18, 46– 47View FIGURES 44 – 53)

Type material. Holotype: 1 ♂, Sakon Nakhon, Phuphan NP, forest, ca. Huay Nam Pung Dam, Thailand, 16 ° 54.713 ’N, 103 ° 54.294 ’E, 289m, Malaise trap, 19–25 November 2006, Sailom Tongboonchai leg ( QSBG); 1 ♂, Phetchabun Nam Nao NP Hell evergreen, Thailand, 16 ° 44.371 ’N, 101 ° 34.549 ’E, height: 834m, Malaise trap, 20– 27 November 2006, Leng Jantiep leg ( IEGU).

Length: ♂ 3.90–3.91mm.

Crown orange with brown longitudinal depression beside gray eyes, two yellowish patches inside depression ( Fig. 46View FIGURES 44 – 53). Face yellow, anteclypeus black apically ( Fig. 47View FIGURES 44 – 53). Pronotum posteriorly with black median triangular patch ( Fig. 46View FIGURES 44 – 53).Scutellum yellowish, apex black, scutoscutellar sulcus brownish ( Fig. 46View FIGURES 44 – 53). Forewing brown; hind wing hyaline ( Fig. 46View FIGURES 44 – 53). Legs yellowish except claws black ( Fig. 47View FIGURES 44 – 53).

Male ventral abdominal apodemes reaching posterior margin of segment 3 ( Fig. 10View FIGURES 10 – 18). Male pygofer with 1 / 2 anterior margin involuted with few setae ( Figs 12, 13View FIGURES 10 – 18). Subgenital plates extended beyond pygofer in lateral view, fused in basal 2 / 3, with 10 macrosetae in one row and ca. 35 microsetae in 3 rows, base slightly wider than width subapically ( Fig. 11View FIGURES 10 – 18). Paramere robust, bent at nearly right angle preapcally with apex slender and evenly tapered, apophysis with lamellar process in basal 1 / 3 and dorsal tooth more distad ( Fig. 14View FIGURES 10 – 18). Aedeagal shaft short, broad, ovoid, strongly compressed, basal process distinctly asymmetrical, branched near midlength with right branch longer and curved more strongly mesad than left branch ( Figs 15, 16View FIGURES 10 – 18). Anal tube process sinuate in ventral view ( Fig. 18View FIGURES 10 – 18). Connective U-shaped ( Fig. 17View FIGURES 10 – 18).

Etymology. The name of the new species is based on the falcate shape of the paramere apex.

Remarks. The new species is similar to I. iochoui Dworakowska  and I. hastata Qin & Zhang  in having the aedeagal process branched, but differs in the position of the branching and in the structure of the branches ( Figs 15, 16View FIGURES 10 – 18). It can be distinguished from I. iochoui  by the paramere with a lamellar process and apex unbranched ( Fig. 14View FIGURES 10 – 18) and the more extensively fused subgenital plates ( Fig. 11View FIGURES 10 – 18). It also differs from I. hastata  in having the anal tube process apically extend in lateral view ( Fig. 18View FIGURES 10 – 18) and the paramere not bifurcated ( Fig. 14View FIGURES 10 – 18).
