拟多棱龙属（Pseudopolydoracf. kempian）和拟多棱龙属（Pseudopolydoracf.reticulata）形态相似，同域分布于日本本州太平洋东岸仙台附近的加茂泻湖。比较了两个种的繁殖、幼虫发育和幼虫形态。幼虫的发育模式。cf. kempi是一种短期营养型的营养型昆虫，具有卵营养和食孤雌的特性; cf. reticulata为长期营养型。每粒蒴果的胚数在两个种之间不同：P为0-16。参见kempi和62-405 for P. cf.reticulata.仅在P. cf. kempi中发现了保育卵。本研究的结果表明，以前的一些研究归因于P. kempi可能是P.cf. reticulata或该复合体中的另一种。
Pseudopolydoracf.kempiandPseudopolydoracf.reticulata, which are morphologically similar, are sympatric in Gamo Lagoon, near Sendai on the Pacific eastern coast of Honshu, Japan. Reproduction, larval development, and larval morphology of these two species were compared. The larval developmental pattern ofP. cf.kempiwas determined to be short-term planktonic with lecithotrophy and adelphophagy, whereas that ofP. cf.reticulatawas long-term planktonic with planktotrophy. The number of embryos per capsule differed between the two species: 0–16 forP. cf.kempiand 62–405 forP. cf.reticulata. Nurse eggs were only found forP.cf.kempi. The results of this study suggest that some previous studies attributed toP.kempimay have been toP.cf.reticulataor to another species in this complex.
