description: Genus Notodoma Lacordaire, 1854
Notodoma Lacordaire, 1854: 266. Type species: Notodoma globatum Marseul, 1855
Diagnosis. Body globose, strongly convex; mostly reddish to blackish brown with yellow maculae on elytral base; head long; mandible slender; frontal stria well-developed; pronotum with complete marginal stria; elytral dorsal striae 1, 2, 4, and sutural stria usually crenulate, complete; propygidium almost hexagonal, strongly convex; prosternal keel with carinal striae, emarginated at apex; mesoventrite bi-emarginate at anterior margin, with a distinct projection at middle; intercoxal disc of metaventrite with a pair of oblique striae, converging at median longitudinal groove; legs slender, with 7–12 denticles on outer margin; tarsal groove of protibia deep, straight (Lacordaire, 1854; Marseul, 1855; Ôhara & Nakane, 1989; Yélamos & Tishechkin, 1996).
A key to species of the genus Notodoma (revised based on Yélamos & Tishechkin, 1996)
