The genus Desmogonius (Digenea: Pronocephalidae) is known only from sea turtles and currently contains two species: D. desmogonius Stephens, 1911 and D. loossi Chattopadhyaya, 1972. The present study describes a third species, Desmogonius baldassinae n. sp. found in a juvenile green sea turtle (Chelonia mydas) from Brazil. The new species is larger than its congeners in all dimensions, with vitellinic fields ending posterior to the ovary. In addition, we present a key for species identification and an emended diagnosis of the genus Desmogonius.
德斯莫吉翁属（Digenea: Pronocephalidae）仅知寄生于海龟，目前包含两个种：德斯莫吉翁氏德斯莫吉翁（Desmogonius desmogonius）斯蒂芬斯，1911 年和洛氏德斯莫吉翁（D. loossi）Chattopadhyaya，1972 年。本研究描述了第三个种，即发现在巴西绿海龟（Chelonia mydas）幼体中的德斯莫吉翁氏秃头德斯莫吉翁（Desmogonius baldassinae n. sp.）。新种在所有维度上都比其同属种大，卵黄腺区延伸至卵巢后。此外，我们提供了一个种鉴定的关键，并对德斯莫吉翁属进行了修正诊断。
