Record #183792:

New genus and species of Polymastiidae (Demospongiae: Hadromerida) from the Antarctic deep sea / Alexander S. Plotkin, Dorte Janussen.

Title: New genus and species of Polymastiidae (Demospongiae: Hadromerida) from the Antarctic deep sea / Alexander S. Plotkin, Dorte Janussen.
Author(s): Plotkin, Alexander S.
Janussen, Dorte.
Date: 2007.
In: Journal of the Marine Biological Association of the United Kingdom. (2007.), Vol. 87(6) (2007)
Abstract: Describes Astrotylus astrotylus collected from Antarctic abyssal zone during 2005 voyage of RV Polarstern. Its peculiar microscleres combine features of asterose spicules and tylostyles. Although similar spicules are observed in Hymeraphia and Discorhabdella, this similarity is convergent as far as radial choanosomal skeleton composed by principal tylostyles and cortical palisade of small tylostyles in Astrotylus confirm its allocation to order Hadromerida and most likely to family Polymastiidae. Close affinity of Atergia, Acanthopolymastia and Tylexocladus with Astrostylus call for phylogenetic analysis of their relations. Astrotylostyles of Astrotylus, cladotylostyles of Tylexocladus and grapnel-like exotyles of Proteleia may be remnants of non-monaxonic ancestral spicule type in Polymastiidae that calls for reconsideration of relations between Hadromerid families.
