A new species of the genus Hybristodryinus Engel, 2005, Hybristodryinus viriosus sp. nov., is described from the mid-Cretaceous Myanmar (Burmese) amber based on a well-preserved female specimen. The keys to fossil species of Hybristodryinus is modified. The new species is most similar to Hybristodryinus mon Perkovsky, Olmi, Müller and Martynova, 2019, but the distance between inner edge of the lateral ocelli is much longer than the distance from the posterior edge of the lateral ocellus to the occipital carina, and which is also much longer than the distance between the inner edge of a lateral ocellus and the median ocellus. This new finding not only broadens the diversity of Dryinidae, but also provides important morphological characters, especially the well-preserved details of the chelate protarsus used for capturing hosts, to enhance our understanding of Hybristodryinus.

Hybristodryinus viriosus sp。的一个新物种，即Hybristodryinus enrio，2005年。nov。是根据保存完好的女性标本从白垩纪中期的缅甸（缅甸）琥珀中描述的。Hybristodryinus的化石物种的关键已被修改。新物种与Hybristodryinus mon最相似Perkovsky，Olmi，Müller和Martynova，2019年，但外侧枕骨内缘之间的距离远大于从外侧枕骨后缘到枕骨隆突之间的距离，并且也比两者之间的距离长得多外侧眼球的内侧边缘和中间眼球。这一新发现不仅拓宽了Dry科的多样性，而且还提供了重要的形态学特征，尤其是用于捕获宿主的螯合螯合物的保存完好的细节，以增强我们对蛇纹龙的认识。
