Remarks.

C. L. Koch (1842) published the description of Mygale plantaris in the same year of Mygale leporina . As Mygale leporina , the procurve anterior row of eyes, the digitiform posterior article of spinnerets, the color pattern and type locality (Brazil) of the syntypes match with Iridopelma (Fig. 220). Therefore, we transfer Mygale plantaris to Iridopelma , making the new combination Iridopelma plantaris (C. L. Koch, 1842) comb. n. Like Mygale leporina , the syntypes of Mygale plantaris are immature specimens. Iridopelma species present very intense ontogenetic changes in color pattern, thus different life stages present very distinct abdominal color pattern. This could be the reason why C. L. Koch (1842) described both forms as two different species when they could be the same. As we can’t assuredly affirm they are the same species, since the types are not adults or even in good condition, we decided to keep them as separate species and to consider Iridopelma plantaris (C. L. Koch, 1842) comb. n. nomen dubium.
