A new species, Tropidion flechtmanni, is described, illustrated, and included in a previous key. Rhinotragus marginatus Perty, 1832 (currently considered a subspecies of R. dorsiger), Rhinotragus dorsiger var. collaris Melzer, 1930, Rhinotragus dorsiger var. vittatus Melzer, 1930, Rhinotragus dorsiger var. amparensis Melzer, 1930, and Rhinotragus apicalis Guérin-Méneville, 1844 are formally synonymized with R. dorsiger Germar, 1823. Variation in pubescence pattern in Pirangoclytus purus (Bates, 1870) is reported, and the species is recorded for the first time in the Brazilian state of Mato Grosso do Sul. Variation in the color of the integument and pubescence in Hemicladus thomsonii Buquet, 1857 is reported, and the species is recorded for the Brazilian states of Mato Grosso do Sul, Rio de Janeiro and São Paulo. New state records are provided for Amorupi fulvoterminata (Berg, 1889), Eclipta vitticollis (Bates, 1873), Steirastoma stellio Pascoe, 1866, Cicuiara nitidula (Bates, 1866), Hesycha inermicollis (Breuning, 1940), and Polyrhaphis gracilis Bates, 1862.
描述并图示了一个新物种——弗莱希特曼氏热带象鼻虫（Tropidion flechtmanni），并将其纳入先前的检索表。1832年的边缘鼻角象（Rhinotragus marginatus Perty，目前被视为背纹鼻角象的一个亚种）、1930年的颈纹背纹鼻角象（Rhinotragus dorsiger var. collaris Melzer）、1930年的带纹背纹鼻角象（Rhinotragus dorsiger var. vittatus Melzer）、1930年的安帕雷背纹鼻角象（Rhinotragus dorsiger var. amparensis Melzer）以及1844年的顶端鼻角象（Rhinotragus apicalis Guérin-Méneville）被正式定为1823年的日耳曼背纹鼻角象（R. dorsiger Germar）的同义词。报告了皮兰戈克利图斯纯象（Pirangoclytus purus，贝茨，1870）的绒毛模式变异，该物种首次在巴西南马托格罗索州被记录。报告了1857年的汤姆森半 cladus 象（Hemicladus thomsonii Buquet）体表颜色和绒毛的变异，该物种在巴西南马托格罗索州、里约热内卢州和圣保罗州被记录。提供了以下物种的新州记录：黄端阿莫鲁皮象（Amorupi fulvoterminata，伯格，1889）、颈带斜纹象（Eclipta vitticollis，贝茨，1873）、星状斯泰拉斯托马象（Steirastoma stellio，帕斯科，1866）、闪亮西库亚拉象（Cicuiara nitidula，贝茨，1866）、无刺赫西查象（Hesycha inermicollis，布勒宁，1940）以及纤细多瘤象（Polyrhaphis gracilis，贝茨，1862）。
