摘要
利用扫描电镜(SEM)描述和说明了飞毛草(paracculina pilosella, Van Kampen et Boschma, 1925)和飞毛草(Sacculina pugettiae Shiino, 1943)幼虫的完整发育过程,包括5个无足虫期和1个鲤期。毛囊孢和pugettiae的发育呈囊状。鹦鹉螺有鹦鹉眼,有末端突起的短前侧角,在分叉支之间有腹侧突起。幼虫缺乏一个浮环,在触角上有6节,在触角基部有一节。塞浦路斯的LO2几乎是直的。断裂带和棘突只存在于雄性幼虫中。两个物种的Nauplii的不同之处在于furca的形态:在P. pilosella中,furca分支较长且不淹没在角质层窝中。蒲公英的触角在内足上有一个侧节,这是蒲公英所没有的。背头盾刚毛1和2a存在于pugettiae nauplii中,而在P. piloselella幼虫中未发现。在毛蕊草中,所有的背刚毛都有近顶孔,而在毛蕊草中,刚毛2的孔向近端移动。有可能刚毛1和2a的存在/缺失是棘科和多棘科的nauplii的显著特征。
Larvae of two parasitic barnacles, Parasacculina pilosella (Van Kampen et Boschma, 1925) (Rhizocephala: Polyascidae) and Sacculina pugettiae Shiino, 1943 (Rhizocephala: Sacculinidae) studied by scanning electron microscopy
The complete larval development of Parasacculina pilosella (Van Kampen et Boschma, 1925) and Sacculina pugettiae Shiino, 1943 including five naupliar stages and one cypris stage is described and illustrated using SEM. P. pilosella and S. pugettiae have a sacculinid type of development. Nauplii possess a naupliar eye, short frontolateral horns with terminal processes, and a ventral process between the furcal rami. Larvae lack a flotation collar, seta 6 on the antennule and a seta on the antennal basis. Cyprids have a nearly straight LO2. Breakage zone and a spinous process are present only in male larvae. Nauplii of the two species differ by the morphology of the furca: in P. pilosella, the furcal rami are longer and not drowned into cuticular sockets. Naupliar antenna of S. pugettiae has a lateral seta on the endopod which is lacking in P. pilosella. Dorsal head shield setae 1 and 2a are present in S. pugettiae nauplii and not found in P. pilosella larvae. In P. pilosella, all dorsal setae have subterminal pores, whereas in S. pugettiae, pores of the setae 2 are shifted proximally. It is possible that the presence/absence of setae 1 and 2a is the distinctive feature of nauplii of the families Sacculinidae and Polyascidae.
期刊介绍:
Arthropod Structure & Development is a Journal of Arthropod Structural Biology, Development, and Functional Morphology; it considers manuscripts that deal with micro- and neuroanatomy, development, biomechanics, organogenesis in particular under comparative and evolutionary aspects but not merely taxonomic papers. The aim of the journal is to publish papers in the areas of functional and comparative anatomy and development, with an emphasis on the role of cellular organization in organ function. The journal will also publish papers on organogenisis, embryonic and postembryonic development, and organ or tissue regeneration and repair. Manuscripts dealing with comparative and evolutionary aspects of microanatomy and development are encouraged.
