( Figs 10–18 View FIGURES 10 – 18 , 46–47 View 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. 46 View FIGURES 44 – 53 ). Face yellow, anteclypeus black apically ( Fig. 47 View FIGURES 44 – 53 ). Pronotum posteriorly with black median triangular patch ( Fig. 46 View FIGURES 44 – 53 ).Scutellum yellowish, apex black, scutoscutellar sulcus brownish ( Fig. 46 View FIGURES 44 – 53 ). Forewing brown; hind wing hyaline ( Fig. 46 View FIGURES 44 – 53 ). Legs yellowish except claws black ( Fig. 47 View FIGURES 44 – 53 ).
Male ventral abdominal apodemes reaching posterior margin of segment 3 ( Fig. 10 View FIGURES 10 – 18 ). Male pygofer with 1/2 anterior margin involuted with few setae ( Figs 12, 13 View 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. 11 View 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. 14 View 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, 16 View FIGURES 10 – 18 ). Anal tube process sinuate in ventral view ( Fig. 18 View FIGURES 10 – 18 ). Connective U-shaped ( Fig. 17 View 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, 16 View FIGURES 10 – 18 ). It can be distinguished from I. iochoui by the paramere with a lamellar process and apex unbranched ( Fig. 14 View FIGURES 10 – 18 ) and the more extensively fused subgenital plates ( Fig. 11 View FIGURES 10 – 18 ). It also differs from I. hastata in having the anal tube process apically extend in lateral view ( Fig. 18 View FIGURES 10 – 18 ) and the paramere not bifurcated ( Fig. 14 View FIGURES 10 – 18 ).
