New diagnostic characters forAmphiodiaandOphiophragmus(Amphiuridae, Ophiuroidea, Echinodermata)

Journal of the Marine Biological Association of the United Kingdom, 2020
AbstractThe generaOphiophragmusandAmphiodiaare amphiurids that are considered taxonomically difficult due to their great resemblance, few diagnostic characters and synonymy problems. Our aim is to redescribe the species using scanning electron microscopy and morphometry of diagnostic structures, and to provide new information for the identification of ...

Symbioses in Amphipholis squamata (Echinodermata, Ophiuroidea, Amphiuridae): geographical variation of infestation and effect of symbionts on the host's light production

International Journal for Parasitology, 1998
Populations of the polychromatic and bioluminescent species Amphipholis squamata from eight locations were examined for internal and external symbionts. At three locations (two in the United Kingdom and one in Papua New Guinea), no symbionts were present, while four species were recovered from the remaining locations: Cancerilla tubulata and ...

Triplodia, replacement name for Triodia A. M. Clark, 1970 (Ophiuroidea: Amphiuridae), non Hübner, 1820 (Lepidoptera: Hepialidae)

Proceedings of the Biological Society of Washington, 2011
Abstract The extant ophiuroid genus Triodia A. M. Clark, 1970 is a junior homonym of the lepidopteran genus Triodia Hubner, 1820. The replacement name Triplodia is herein proposed to accommodate Triodia abdita A. M. Clark, 1970, assigned to this monotypic genus.

Ophiodaphne scripta (Ophiuroidea: Amphiuridae), a brittle star exhibiting sexual dimorphism and epibiosis: first record from India, with notes on adaptations, systematics and distribution

Marine Biodiversity, 2013
Ophiodaphne scripta (Koehler, 1904) is an amphiurid brittle star exhibiting an unusual form of conspicuous sexual dimorphism and epibiosis. The males are much smaller and exist as epibionts on the larger female. These male–female pairs, attached mouth-to-mouth, are in turn epibionts on cake urchins such as Echinodiscus auritus Leske, 1778, attaching ...

Taxonomic status of the genera Amphipholis and Microphiopholis (Amphiuridae: Ophiuroidea): microstructural analyses

Zoological Journal of the Linnean Society
Abstract Microphiopholis Turner, 1985 has been characterized by the presence of a ventrodorsal perforation in the arm vertebra and disc covered by small scales. However, its validity has been questioned based on these characters. This study evaluates whether the perforation in the arm vertebra and the size of the scales are exclusive ...

Direct development of the brittle star Amphiodia occidentalis (Ophiuroidea, Amphiuridae) from the northeastern Pacific Ocean

Invertebrate Biology, 2006
Abstract. The highly modified development of the brittle star Amphiodia occidentalis is described from post‐fertilization to the juvenile stage. Fertilized eggs are negatively buoyant, ∼190 μm in diameter, surrounded by a thick hyaline layer and a tough fertilization envelope.
