Diagnosis: This species resembles I. frater ( Marshall) and is distinguished by the following characters: Colour black with slightly bluish green vestiture, margins of elytra near humeral fold with dense, golden yellow vestiture. Vertex with a minute, circular fovea. Prothorax as long as broad. Antennae with first segment of funicle 1.4x as long as second. Scrobes nearly square anteriorly. Elytral vestiture with obovate reddish brown scales, with clefted base and 10–12 ridges. Male genitalia with apophyses 0.44x as long as median lobe, manubrium with apex broadened and bulbous, shaft of spiculum gastrale 0.88x as long as median lobe.

Description: Colour black with apple green or slightly bluish green vestiture, more or less shining, margins of elytra especially near humeral fold with dense, golden yellow vestiture. Head 1.05x as long as rostrum, upper surface moderately convex, vertex with a minute, circular fovea. Rostrum shallowly impressed at middle dorsally, as long as broad; anterior margin only 0.85x as broad as posterior margin; median furrow uniformly broad, distinct; lateral carinae running through length of rostrum; sides narrowed anteriorly, where it is slightly dilated; scrobes broadest at middle, squarish anteriorly, but divergent and pointed posteriorly. Eyes dorsal, moderately convex (figs. 24 and 49). Antennae dark brown; scape gradually clavate; funicle with first segment 1.4x as long as the second, third and fourth equal, fifth and sixth equal; club with distinct rows of dense hairs on its joints (fig. 74). Prothorax as long as broad, broadest at middle, 1.09x as broad as the posterior margin; sides rounded; anterior margin only 0.62x as broad as the posterior margin, truncate dorsally and oblique laterally, posterior margin subtruncate, basal lobe emarginate; upper surface with very shallow, scattered punctations, interspaces obscurely granulate. Legs with hind tibial apex without any dense, golden yellow hairs. Elytra ovate, with basal margin strongly raised, its external angle acute, humeral fold prominent and projecting, more or less strongly impressed on declivity, posterior declivity sinuate; apices rounded; stria with punctations deep, intervals broad, plain, not raised; outline of posterior declivity not distinctly sinuate; elytral vestiture with obovate, reddish brown scales with clefted base and with 10–12 ridges (fig. 128).

Male genitalia: Aedeagus with median lobe comparatively slender at middle, broad at base and apex, length: breadth ratio 9:1, apex rounded, broadest at junction between apophyses, apophyses 0.44x as long as median lobe (figs. 240–241). Tegmen with dorsal piece 2.5x as broad as the basal piece; parameres short, slender and pointed; manubrium moderately long, slender, 0.5x as long and 0.2x as broad as the median lobe, uniformly thick, with apex much broadened and bulbous (fig. 242). Spiculum gastrale with shaft 0.88x as long as the median lobe, uniformly thick, apex deflected and bluntly rounded; basal prongs subequal, their apices broadly rounded (fig. 182).
