Diagnosis. This species is similar to I. gauldi Marsh. It   can be distinguished from the other species of the genus by the sinuate transverse furrow on the second metasomal tergite, which is placed close to its anterior margin and is sometimes only very weakly indicated, and by the median longitudinal furrow on posterior edge of mesoscutum.

Description. Female. Body length 2.5–2.7 mm. Head: 1.8 times wider than median length. POL 1.3–1.5 times Od, 0.4–0.5 times OOL. Eye 1.1–1.2 times longer than wide, transverse diameter of eye 2.0 longer than temple (dorsal view). Malar space 0.4 times eye height. Width of hypoclypeal depression 0.9–1.1 times distance from edge of depression to eye. Antenna filiform, with 20 antennomeres. First flagellar segment 3.8 – 4.0 times longer than wide, 1.0– 1.1 times longer than second segment. Penultimate segment 2.5 times longer than wide, 0.7 times as long as first segment.

Mesosoma: 2.0 times longer than high, 1.7 times longer than wide. Mesoscutum 0.7 times as long as wide and uniformly rounded. Notauli barely distinguishable on antero-lateral edge of mesoscutum as scrobiculate sculptures, and very weakly indicated by two furrows on dorsal surface of mesoscutum, only visible at some angles of light. Prescutellar depression with five transverse carinae. Sternaulus about 0.6 times as long as mesopleuron.

Wings: Fore wing with pterostigma about as long as R. Vein r 0.8–0.9 times as long as 3 RSa, 0.3–0.4 times as long as 3 RSb, and 0.7 times as long as 2 RS. Vein (RS+M)a slightly sinuate. Discal cell 2.0– 2.1 times longer than wide.

Legs: Hind coxa with distinct basoventral tooth. Hind femur 2.6 times longer than wide; hind tibia 4.0 times longer than wide and 2.8 times longer than basitarsus.

Metasoma: Almost as long as head and mesosoma combined. First tergite wider than long, 0.7 times as long as its apical width; second tergite 0.3 times as long as wide and 1.1 times longer than third tergite. Ovipositor sheath 0.8 times as long as metasoma.

Sculpture and pubescence: Head mostly coriaceous except malar space, which is almost smooth. Pronotum coriaceous, pronotal furrow scrobiculate. Mesoscutum strongly coriaceous, with a single median impression on posterior edge; notauli absent, only indicated by a few rugose sculptures on antero-lateral edges of mesoscutum, which continue as two very weak furrows barely visible at some angles of light. Scutellum coriaceous. Mesopleuron strongly and uniformly coriaceous; subalar groove and sternaulus scrobiculate. Metapleuron coriaceous, turning weakly rugose on posterior edge. Propodeum with basolateral areas coriaceous; areolar carinae present, enclosing median areola crossed by several carinae. Coxae mostly smooth, mid and hind coxae dorsally coriaceous. Hind femur slightly coriaceous, turning smooth ventrally. First metasomal tergite with median area clearly delimited by carinae; median area mostly coriaceous, turning striate on posterior edge, lateral areas striate; second tergite longitudinally striate, occasionally with weak granular sculpture between striae, with a transverse and sinuate furrow very close to anterior margin of tergite on lateral areas; third tergite mostly coriaceous, striate on anterior edge; remaining tergites coriaceous, turning smooth on posterior edge. Head except eyes, mesoscutum, and pronotum covered by short, erect setae. Mesopleuron glabrous medially. Propodeum and metapleuron sparsely setose. Hind tibia with short semi-erect setae, more dense ventrally. Metasoma with first and second tergites with sparsely and uniformly distributed short setae, remaining tergites mostly glabrous, only with a transverse row of sparse setae subapically. Ovipositor sheath uniformly covered by long, erected setae.

Male: Similar to female. Antennae with 18 antennomeres. Hind wing with pterostigma at junction of SC+R and r-m.

Biology. Unknown.
