  • Comparative notes. Ytu thanatos sp. nov. is similar to species from the Ytu zeus group because of the presence of a carina on the first ventrite and its total length greater than 1.4 mm. It is especially similar to Y. cleideae Vanin because both have 13 striae on elytron. However, Ytu thanatos sp. nov. presents a different sculpture on pronotum and elytron, the pronotum having a group of depressions that form a skull-like raised area, not present on Y. cleideae, and the elytron of Ytu thanatos sp. nov. does not have even elytral intervals keeled like on Y cleideae (Vanin 1991, fig. 1). The male genitalia of these two species are completely different, being curved and abruptly bent downward at apex and forming an acute hook in Y. cleideae (Vanin 1991, figs. 2 and 4) and weakly curved but not forming a hook in Y. thanatos.
