Bates (1881b) described Tyrinthia reversa based on a single specimen from Brazil (Rio de Janeiro) (Fig. 36). Lameere (1883) transferred the species to Hemilophus Audinet-Serville, 1835, but Aurivillius (1923) kept the species in Tyrinthia Bates, 1866. Later, Martins & Galileo (1991b) transferred T. reversa to their new genus Icimauna.
Martins & Galileo (2014b) described Tyrinthia humeralis based on a series of males and females from Brazil (Goiás). Examination of the paratypes deposited at MZSP (Fig. 31) showed that T. humeralis lacks the typical humeral carina present in the species of Tyrinthia. Comparison with specimens of Icimauna reversa deposited in the MZSP collection (Figs 32–34) makes it clear that T. humeralis is simply a variation of I. reversa. Thus, T. humeralis is synonymized with I. reversa.
Mehl et al. (2015) describe Eranina tomentilla based on a single female from Paraguay (Fig. 35). Along with T. humeralis, E. tomentilla is simply another color variation of Icimauna reversa, and hence is also synonymized with it.
Icimauna reversa shows notable variation in the color of elytral pubescence (Figs 31–36), and also some variation in pronotal pubescence. However, there are no other morphological characters evident which allow separation of the specimens.
