Differential diagnosis: Pronotum subquadrate, entirely orangish yellow, without dark patches; elytra brown with apical yellow patches; males: fore femur swollen, with distinct ventral tooth; ventrite VIII smooth, without ridges; aedeagus with right prolongation of tegmen truncate, short, narrow; left setiferous prolongation absent; females: ventrite VII short, wide, distal margin projected posteriorly. This species differs from M. xerophilus sp. nov. by having larger size, pronotum, thorax and abdomen spotless, pale to orangish yellow, fore femur of males with a truncate ventral tooth. Distribution: Brazil ( Minas Gerais , Espírito Santo , Rio de Janeiro , São Paulo , Paraná and Santa Catarina states) ( Fig. 66-67 ). Localities description: This species is widely found along the southeastern and southern Atlantic forest, from the seashore to highlands over to 1,600 m , and from humid costal to dryer inland areas. Natural history: Macromalthinus brasiliensis is a rath- er common species in southeastern Brazil , frequently collected with malaise traps. Despite the abundance of specimens, little is known about their natural history. Mendes et al. (2015) studied the range of altitudinal distribution of Macromalthinus brasiliensis in the Atlantic forest in Parque Nacional da Serra dos Orgãos, Rio de Janeiro state . The authors collected 799 specimens distributed between 350 m and 1,250 m altitude, with a peak of abundance at 700 m altitude and equivalent ration between males and females. Larvae of this species were found in a gully and fed on termites ( Biffi & Casari, 2017 ). In the laboratory, females of M. brasiliensis were observed laying large masses of eggs under the substrate.
