Neoma gen. nov.

Etymology. Neoma , is formed from the first two letters of Macrotomini and the Greek prefix neos (= new); the gender is feminine.

Type species. Mallodonopsis corrosus Bates, 1879 .

Description. Size from medium to large (up to 4.0 cm).

Male. Body not depressed. Eyes large. Epistoma wide. Labrum not coplanar with the epistoma. Hypostomal area slightly depressed, rugose-punctate or anastomosedly punctate. Galea abundantly pilose, reaches about the middle of second palpomere of maxillary palpi. Mandibles, at most, as long as half the length of head; dorsal carina wide, not distinctly separated from the outer and inner surfaces. Antennae not reaching the apex of elytra; scape reaching the posterior ocular edge (sometimes surpassing).

Prothorax transverse; anterior angles slightly projected forward; lateral angles acute. Pronotum laterally distinctly inclined downwards; lateral margins weakly explanate, crenulate-spinose (sometimes only spinose); disc plate shining; laterally coarsely rugose-punctate; without sexual dimorphism (sexual punctation). Prosternum with sexual dimorphism. Proepimera and proepisterna with the same kind of sexual dimorphism of the prosternum. Prosternal process wide, surpassing the apex of procoxae. Metepisterna narrow; weakly, widely concave centrally (width at central region equal to about 0.2 times the length). Legs moderately short. Profemora strongly asperate-punctate, mainly on ventral surface; meso- and metafemora somewhat asperate on ventral surface, mainly in mesofemora. Tibiae thick, distinctly enlarged towards apex (mainly the protibiae); protibiae with asperities on ventral face; meso- and metatibiae without asperities.

Female. Antennae reaching from the apex of the anterior third of elytra to almost middle; scape usually, not or just reaching the posterior edge of eyes. Anterior angles of the prothorax projected forwards; lateral margins of the pronotum more distinctly spinose than in males. Femora and tibiae not asperate.
