一个鲜为人知的leucosiid蟹，Pseudophilyra punctulata Chen & Ng，2003，最初描述的基础上一个不成熟的男性正模和一个不成熟的女性副模来自新加坡，被重新发现和重新诊断的基础上的材料来自泰国，菲律宾和琉球群岛（日本）。此外，根据日本本州岛三重县的材料，描述了一个与P.punctulata关系密切的新种，P.parilis。该新种与P.punctulata的区别在于其甲壳侧缘的粗颗粒和生殖足的不同形状。并将三齿拟石蛾（Pseudophilyra tridentataMiers，1879）与点石蛾（P.punctulata）和小石蛾（P.parilis n.由于甲壳和附属物的整体形态非常相似，但可以很容易地通过甲壳和胸胸骨表面更光滑，甲壳形状不同以及螯掌更粗壮来区分。在日本以外的地区，可能有超过一个种的三齿原甲。
A poorly known leucosiid crab, Pseudophilyra punctulata Chen & Ng, 2003, originally described on the basis of an immature male holotype and an immature female paratype from Singapore, is rediscovered and rediagnosed on the basis of material from Thailand, the Philippines and the Ryukyu Islands (Japan). In addition, a new species closely related to P. punctulata, P. parilis, is described and illustrated on the basis of material from Mie Prefecture, Honshu mainland of Japan. The new species is distinguished from P. punctulata by the coarser granules bordering the lateral carapace margins and the different shape of the gonopods. Pseudophilyra tridentata Miers, 1879, is also compared with P. punctulata and P. parilis n. sp. because of the close similarities in the overall morphology of the carapace and appendages, but can easily be differentiated by the smoother carapace and thoracic sternum surface, different shape of the carapace and the stouter cheliped palm. It is possible that previous records of P. tridentata outside Japan might contain more than one species.
