Genus Indomias Marshall (Gender: Masculine)

Type species: Indomias prasinus ( Boheman, 1845) ; designated by Marshall, 1941: 350; Alonso- Zarazaga & Lyal, 1999: 181.

General description: Colour black to piceous, covered by varying shades of greenish vestiture viz., pale to dense or metallic green to grey or blue grey, with stripes or patches of yellowish vestiture. Head Eyes dorsal, lateral or dorsolateral, variable in size and curvature. Rostrum longer than head but in few species shorter, shallowly or deeply emarginate at the apex, plain in few species, always with a median furrow, and also a lateral furrow bordered on each side by a carina; scrobes sublinear and always curving downwards at some distance from the eye; mandibles with a very conspicuous projecting scar, mandibular processes deciduous, epistome quite undefined, mentum with only two setae. Antennae with the scape hardly exceeding the middle of the eye, cylindrical, slender at the base, either gradually or abruptly clavate and curving slightly forwards when erect; funicle with segments one and two more elongate and subequal, equal in few species, segments three to six subequal and generally bead-like, segment seven longer, broader and subconical, club conical and distinctly four jointed. Prothorax truncate at anterior margin, posterior margin truncate or subtruncate, narrowly elevated in few species, sides rounded, anterior margin narrower than posterior margin, anterior margin with conspicuous vibrissae at the sides, the gular margin narrowly sinuate. Prosternum with front coxae either separated or contiguous and always nearer to its anterior margin; mesosternum with epimera narrow, much smaller than episterna and not separating them from base of elytra; metasternum as long as or slighlty shorter than median coxae, the episterna narrow, the episternal suture distinct throughout, the hind coxae not reaching the elytra. Scutellum distinct and rounded. Elytra ovate, with a humeral fold, the lateral margin shallowly sinuate above the hind coxae, but without a distinct excision to receive the head of the metasternal episternum, punctatostriate, intervals broader than striae. Legs of variable length, the femora clavate, the front pair slightly thicker than others, front tibiae longer than the rest, strongly curved, denticulate internally and with a sharp, apical spine, directed inwards at right angles; median pair straight, produced internally at the apex with a short, slender spine; hind pair straight and not produced internally at the apex, hind tibiae never denticulate, hind tibial apex with a well developed outer bevel and an inner flange, with two rows of setae; tarsi with third segment broadly bilobate, claws connate or fused throughout, except at apex where they are free. Venter with the intercoxal process narrower, arcuate or angulate, suture between ventrites one and two distinct throughout, ventrite two, 1.5– 2 x as long as three and four together, throughout its length.
