摘要：从单个卵到性成熟成虫的发育观察，描述了长尾丙烯（Propallene longiceps）的胚胎后发育。受精卵在孵化时完成第一次蜕皮，6 ~ 7天后孵化为二龄幼虫。未观察到原虹膜幼虫期。长尾海参幼虫在附着幼虫期蜕皮3次，在自由游动幼虫期蜕皮6次。第九次换毛时，幼虫变成了成虫。一枚受精卵要经过5个月才能变成成虫。讨论了伞蝇科类内关系的几个方面。
Summary Post embryonic development of a pycnogonid, Propallene longiceps, is described from observations of the development of an individual egg to a sexually mature adult. A fertilized egg hatches after 6 to 7 days as a second instar larva, because it completes the first moulting at the time of hatching. No protonymphon larval stage was observed. The larva of P. longiceps undergoes 3 moults during its attaching larval stage and 6 moults during its free-swimming larval stage. With the 9th moult, the larva becomes an adult. It took about 5 months for a fertilized egg to become an adult in P. longiceps. Some aspects of the intraclass relationship of the Family Pallenidae are discussed.
