The first finds of the fossil remains of the members of the genus Chodsigoa outside China are described from the Pleistocene of northern Vietnam. They are assigned to C. caovansunga Lunde, Musser et Son, 2003 (a maxillary fragment with A-M, an isolated M, and a dentary with I and P-M) from the Middle Pleistocene of the Tham Hai cave (Lang Son Province) and C. hoffmanni Chen et al., 2017 (a maxillary fragment with P-M) from the Upper Pleistocene of the Lang Trang cave (Thanh Hoa Province). The described specimens are the first fossil finds of these species. They indicate that representatives of the genus Chodsigoa in Vietnam spread to the south much further in the Pleistocene than today.
描述了越南北部更新世化石属 Chodsigoa 成员的首次发现。它们被归入 C. caovansunga Lunde、Musser et Son,2003(来自朗松省 Tham Hai 洞穴的中更新世的一个上颌骨碎片,带有 A-M、一个孤立的 M,以及一个带有 I 和 P-M 的下颌骨)和 C. hoffmanni Chen 等人,2017(来自 Thanh Hoa 省 Lang Trang 洞穴的上更新世的一个上颌骨碎片)。描述的标本是这些物种的首次化石发现。它们表明,越南的 Chodsigoa 属代表在更新世时期向南扩散的范围比今天要远得多。
