( Figs. 16-19 )

Material examined. Holotype ♂ from Thailand, Chiang Mai Province, Doi Inthanon National Park, Namtok Monthatarn , 600 m, 98° 55’ N, 18° 49’ E, 25 September-12 October 2002, Malaise trap, Chiang Mai University team ( PMSL) . Paratypes: Thailand: Type locality, 13-14 February 2003, 1♂ ( PMSL) . Type locality, 16-17 November 2002, 1♂ ( PMSL) . Loei Province, Phu Hin Rongkla National Park, Huai Man Daeng Noi , 1600 m, 101° 03’ N, 16° 57’ E, 21 October 2002, I. Sivec, 1♂ ( PMSL) .

Adult habitus. General color brown to dark brown. Head, pronotum and wings dark brown; pronotum with obscure rugosities. Palpi and antennae brown, first two segments of antennae darker. Legs mostly dark brown but hind femora with pale band in distal third and fore and mid femora with pale dorsal area; all femora pale on proximal half of ventral surface; tibiae and tarsi uniformly dark brown.

Male. Forewing length 7 mm. Epiproct long and broad, widest near midlength and bearing a broad mesal keel in dorsal aspect ( Fig. 16 ); apex terminating in a small rounded projection; in ventrolateral aspect, ventral sclerite terminates in a subapical, rounded spinous structure ( Fig. 17 ). Outer lobe of paraproct slender for much of length, strongly sclerotized and turned sharply outward to an acute apex ( Figs. 18-19 ). Vesicle short, wide and slightly rounded ( Fig. 18 ); hypoproct very broad and somewhat shield-shaped.

Female. Unknown.

Larva. Unknown.

Etymology. The matronym honors Professor Dr. P. Chantaramongkol in recognition of her leadership of the Chiang Mai University team during this project.

Diagnosis. The key above places this species near I. malickyi but the two are not apparently closely related. The single, long, slender and apically bent outer paraproct lobe of this species ( Figs. 18-19 ) is distinctive.
