A new genus, Graziasternum gen. nov., with two new species, Graziasternum graziae sp. nov. and Graziasternum joceliae sp. nov. are described. According to external thoracic and genital structures, this new genus is considered to be the closest extant relative known to the genus Placosternum Amyot Serville. Discussion of its possible phylogenetic position based on structure comparison, with the discussion on the importance of the characteristics of the thoracic sterna, the genital structures with other genera or groups of genera that share similar structures is given. Additionally, the two new species are keyed and illustrated.
描述了一个新属，Graziasternum 属，新属包含两个新种，Graziasternum graziae 种和 Graziasternum joceliae 种。根据外部胸和生殖器结构，这个新属被认为是与现生的 Placosternum Amyot Serville 属关系最近的属。根据结构比较讨论了它的可能系统发育位置，并讨论了胸板特征的重要性，以及与具有相似结构的其他属或属群的生殖器结构的重要性。此外，还对这两个新种进行了键控和说明。
