Nodostoma is a genus of leaf beetles found in eastern and southern Asia, distinguished by their transverse, anteriorly strongly narrowed pronotum with more or less distinctly angulated sides (Jacoby 1908).

Pronotum generally transverse, narrowed in front, rarely subcylindrical, more or less angulate at sides near base, with narrow sulcus near anterior margin. Elytra generally wider at base than thorax, more or less deeply depressed below base, punctate-striate, sometimes metallic, generally flavous or fulvous. Prosternum broad, subquadrate, base truncate. Legs rather long; femora incrassate, frequently with small tooth; intermediate and posterior tibiae emarginate at apex, claws appendiculate.
