Understanding how animals evolve to become parasites is key to unravelling how biodiversity is generated as a whole, as parasites could account for half of all species richness. Two significant impediments to this are that parasites fossilize poorly and that they retain few clear shared morphological features with non-parasitic relatives. Barnacles include some of the most astonishingly adapted parasites with the adult body reduced to just a network of tubes plus an external reproductive body, but how they originated from the sessile, filter-feeding form is still a mystery. Here, we present compelling molecular evidence that the exceedingly rare scale-worm parasite barnacle Rhizolepas is positioned within a clade comprising species currently assigned to Octolasmis , a genus exclusively commensal with at least six different phyla of animals. Our results imply that species in this genus-level clade represent an array of species at various transitional stages from free-living to parasitic in terms of plate reduction and host-parasite intimacy. Diverging only about 19.15 million years ago, the route to parasitism in Rhizolepas was associated with rapid modifications in anatomy, a pattern that was likely true for many other parasitic lineages.

Abstract

Merlionia zeeae , a new species belonging to a new genus, is described as a member of the cyclopoid family Anthessiidae (Copepoda), based on both sexes collected off the coast of Singapore. The new species was found in the gill cavities of the longnosed stargazer, Ichthyscopus lebeck (Actinopteri: Perciformes: Uranoscopidae), although almost all members of the family are associated with molluscan hosts. However, this copepod is not similar to other genera of the family Anthessiidae due to possessing the following characters: the curved hook-like antenna, which is similar to that of the family Chondracanthidae in both sexes; the distal portion of the maxilla covered with numerous spinules; and the lack of the maxilliped in the female. Both maximum likelihood and Bayesian inferences using partial SSU (18S) ribosomal RNA genes strongly supported a monophyletic clade formed by the new genus, and three anthessiid genera in this study. However, it was not supported that Anthessiidae and Chondracanthidae are closely related. Therefore, the new genus is considered to be a highly transformed member of the former, and the chondracanthid-form antenna might therefore be a product of convergent evolution attributable to the host-switching event from molluscs to fishes.

Abstract

Temnocephalids are ectosymbionts of various freshwater animals. A species tentatively identified as Temnosewellia aff. vietnamensis (Platyhelminthes: Rhabdocoela: Temnocephalidae) is reported based on materials collected from the body surface of the freshwater crabs Eriocheir japonica (Brachyura: Varunidae) and Geothelphusa exigua (Potamidae) in Kagoshima, southern Japan. The temnocephalid is characterized as follows: the cirrus composed of a cone-shaped shaft and a cylindrical introvert 42–77 μm long; the introvert covered with approximately 30 vertical rows of fine sharp spines; the four seminal receptacles; and a long, curved oviduct with vaginal gland; a pair of gland cells (Haswell's cells) present anterior to the excretory ampullae. Bayesian inference trees using partial nuclear 28S rDNA (28S) and mitochondrial cytochrome c oxidase subunit I (COI) genes supported that the specimens collected from both crab species are conspecific but these also showed the geographical variations among them on both 28S and COI. The previous records of the genus Temnosewellia in East to South Asian countries are assembled and shown on the map (fig.7, this paper).

<title>Abstract</title>Two species of dirivultid copepod (Siphonostomatoida), <italic>Stygiopontius senckenbergi</italic> Ivanenko & Ferrari, 2013 and <italic>Dirivultus kaiko</italic> sp. nov., were discovered from hydrothermal vent fields in the Okinawa Trough, the western North Pacific. Since <italic>S. senckenbergi</italic> was originally described based on two adult males from the New Ireland Fore-Arc system, Papua New Guinea, the discovery here represents the second record. This species was attached on ventral setae covered with filamentous bacteria of the deep-sea squat lobster <italic>Shinkaia crosnieri</italic> (Decapoda: Munidopsidae). The female of <italic>S. senckenbergi</italic> is described for the first time as well as the nauplius I and the copepodid IV. Sexual dimorphism is shown on several appendages (i.e. antennule, leg 2 and leg 5). The nauplius I shows typical lethithotrophic characteristics. <italic>Dirivultus kaiko</italic> sp. nov., which was found on the tentacular crown of the siboglinid tubeworm <italic>Lamellibrachia columna</italic>, differs from its two congeners by the antennule, maxilliped and leg 5 of both sexes. These are the second and third dirivultid species to be reported from Japan.
