(figs. 13, 41, 64, 101, 143 and 160)

Diagnosis: This species is resembles I. kraatzi (Heller) and I. menoni sp. nov., from which it is distinguished by the following characters: Prothorax 1.25x broad as long, its greatest width is less than greatest width of elytra. Fore legs with apex of femur never black and wrinkled. General body size with length: breadth ratio equal to or more than 3:1. Female genitalia with spiculum ventrale having its basal plate ovate, spermatheca with proximal arm as long as distal arm.

Description: Colour black, with dull green or apple green vestiture; sides of prothorax and elytra with metallic green vestiture, rarely interspersed with reddish tinged scales. Head as long as rostrum, upper surface moderately convex, finely coriaceous, with shallow confluent punctations; vertex impressed. Rostrum shallowly impressed at the middle dorsally, 1.1x as broad as long, breadth at anterior margin 0.77x as that of posterior margin; median furrow uniformly broad throughout, reaching the middle of eyes; lateral carinae do not extend beyond the anterior margin of eyes; sides narrowed towards anterior margin, but almost parallel; scrobes narrowed towards anterior margin of rostrum, uniformly broad, 0.6x as long as rostrum, smoothly rounded posteriorly. Eyes almost lateral, circular, moderately convex (figs. 13 and 41). Antennae piceous; scape very slender; with first funicle segment 1.43x as long as second, thick and broad (fig. 64). Prothorax subcylindrical, 1.25x as broad as long, its breadth at middle only 1.02x as the breadth at posterior margin; sides rounded at the front and constricted behind; anterior margin 0.75x as broad as the posterior margin, truncate dorsally, vertical laterally; posterior margin truncate, its basal lobe emarginate; upper surface rugosely punctate, interspaces obscurely granulate, median stria deep, found at the posterior two thirds. Legs with hind tibial apex having well-developed, dense golden yellow hairs. Elytra broadly ovate, with basal margin slightly raised, humeral fold present but not prominent; apices slightly mucronate; stria finely punctate, intervals broad, almost plain, second and third impressed at the posterior declivity, elongate scales inconspicuous; elytral vestiture with broadly ovate scales, having patches of granulated areas (fig. 101).

Female genitalia: Spermatheca with proximal arm subequal to distal arm, as long as and 2x as broad as the cornu, angle between them obtuse; nodulus triangular, with apex pointed; ramus almost cuboidal, 2x as broad as nodulus; cornu long, tubular, its apex bent and bluntly rounded (fig. 143). Spiculum ventrale with shaft thickened towards apex, otherwise slender; basal plate ovate, 1.5x as long as broad, only 0.2x as long as the shaft, its apex rounded with 5–6 short, stout hairs (fig. 160).

Length: female, 9.54 mm; Breadth: female, 3.24 mm.

Holotype: 1 female, INDIA: without locality and collector name, forest campus, 8.IV.1994, on Albizzia lebbeck ( NPC).

Distribution: India.

Etymology: It is named after the host Albizzia lebbeck on which it was found.
