Diagnosis: This species resembles I. kraatzi (Heller) and is distinguished by the following characters: Rostrum 1.1x as broad as long, median furrow broad and almost fused with anterior margin but narrowed and pointed posteriorly. Antennae with club distinct i.e., segments narrowing and telescoped from base to apex. Prothorax 1.01x as broad as long. Male genitalia with apex of manubrium enlarged, conical, notched; spiculum gastrale with apex of shaft truncate and horn like. Length: breadth ratio of general body size either equal to or more than 3:1.
Description: Colour black with pale or dull green vestiture. Head as long as rostrum, upper surface moderately convex, with deep, scattered punctations hidden behind vestiture. Rostrum shallowly impressed, 1.1x as broad as long, anterior margin only 0.75x as broad as posterior margin; median furrow broad and almost fused with anterior margin, but narrowed and pointed posteriorly; lateral carinae complete and seen throughout the length of rostrum, extending beyond anterior margin of eyes atleast up to 0.25x as the length of eye; scrobes broader and broadly rounded anteriorly but much narrowed, sharply pointed and converging posteriorly. Eyes dorsal, moderately convex and cylindrical (figs. 23 and 51). Antennae dark brown; scape abruptly clavate; funicle with first segment 1.25x as long as the second, third and fourth equal, fifth and sixth subequal; club distinct due to the segments narrowing, and getting telescoped from base to apex (fig. 75). Prothorax 1.01x as broad as long, its breadth at middle 1.1x as broad as posterior margin, sides rounded; anterior margin only 0.87x as broad as posterior margin, truncate dorsally and acute laterally, posterior margin truncate; sides rounded; upper surface shallowly punctate, interspaces granulate. Legs with hind tibial apex having well developed, dense, golden yellow, short hairs. Elytra with basal margin strongly raised, its external angle acute, humeral fold present but not projecting; apices rounded; stria deeply punctate; intervals broad, convex; elytral vestiture with predominant scales subovate, reddish brown, with 8–10 ridges (fig. 129), less predominant elongate, brown, with a short pedicel, inner core opaque, granulated, with 4–5 ridges (fig. 130).
Male genitalia: Aedeagus with median lobe slender, broadest at junction with apophyses, length: breadth ratio 6:1, membranous at middle; in profile arcuate at base, its apex blunt, apophyses 0.66x as long as median lobe (figs. 249–250). Tegmen with dorsal piece 5x as broad as basal piece; parameres long, papillate, their apices rounded; manubrium 0.5x as long as median lobe, uniformly thick, with an enlarged, notched, conical apex (fig. 251). Spiculum gastrale with shaft as long as median lobe, uniformly thick, its apex truncate, horn like; basal prongs equal, their apices truncate and pointed (fig. 184).
Length: male, 9.03 mm; Breadth: male, 2.85 mm.
Holotype: 1 male, INDIA: Kerala: Malabar: Dhony forests, 26, V.1922, Coll. Ramakrishna (NPC).
Distribution: India: Kerala.
Etymology: The name I. dubeyi sp. nov. is derived from and in the honour of Dr. O. P. Dubey, Ex- Assitant Director General, Plant Protection, ICAR, New Delhi, particularly for his sincere interest and encouragement for taxonomic studies on insects.
