Tricorythodes molinerii sp. n. is described and illustrated based on nymphs from southeastern Brazil. The new species can be distinguished from other species of Tricorythodes Ulmer by the following characters: 1) genal projection present; 2) maxillary palp bi-segmented, with short apical seta; 3) pronotum with well developed anterolateral projection; 4) dorsum of fore femora with a transverse row of setae; 5) tarsal claws without marginal denticles and with one submarginal denticle on each side; 6) operculate gills triangular, shaded with black, and with whitish mark in subbasal zone; and 7) very large size.
基于来自巴西东南部的若虫，描述并图示了新物种莫氏三栉角蜉（Tricorythodes molinerii sp. n.）。该新物种可通过以下特征与三栉角蜉属（Tricorythodes Ulmer）的其他物种区分开来：1）存在颊突；2）下颚须分两节，具短的顶端刚毛；3）前胸背板具发育良好的前侧突；4）前足股节背面有一横排刚毛；5）跗爪无边缘小齿，两侧各有一个亚边缘小齿；6）鳃盖呈三角形，有黑色阴影，基部区域有白色斑；7）体型非常大。
