Comments. Eburodacrys sulfurifera was described by Gounelle (1909) from Brazil (Goiás and Ceará); Eburodacrys amabilis was described by Galileo & Martins (2009) from French Guiana and compared and differentiated from the former by the lateroposterior eburneous callosities notched at anterior margin (not notched in E. sulfurifera) and by the presence of a black apical elytral band (the authors did not mention the elytra apex in E. sulfurifera, but by the context it is possible to infer that it would be absent). A study of the type material, the original descriptions and the examination of more than 30 specimens allowed me to observe variability of the characters above mentioned (Figs. 26–33).

The lateroposterior eburneous callosities can be notched or not, and there are specimens with different degrees of notching. Regarding the black band at the apex of the elytra, it is possible to see specimens with and without a notch and having or not having black band. It is interesting to point out that these variations are not related to geographical distribution. Thus, it is possible to find specimens with eburneous callosities notched or not and with or without a black apical elytral band through all the geographical distribution of the species.
