Seymour Island

The james ross basin, situated on the eastern margin of the Antarctic Peninsula, has yielded an extensive fauna of decapod crustaceans spanning Late Cretaceous through Eocene time. To date, 28 species in 22 genera and 18 families have been described (Feldmann, 1992; Feldmann, Tshudy, and Thomson, 1993), making this the most diverse fossil decapod fauna in the Southern Hemisphere. Within the basin, Seymour Island alone contains rocks of the Eocene age La Meseta Formation from which seven species of crabs, one galatheid, and one species of callianassid ghost shrimp have been described (Feldmann and Zinsmeister, 1984; Feldmann and Wilson, 1988; Feldmann, 1992). The fauna of the La Meseta is remarkable also because, although the organisms are preserved in rocks deposited in moderate- to high-energy, shallow-water habitats (Elliot and Trautman, 1982), many of the species represent early occurrences of taxa with living descendants that are characteristic of deeper water, lower latitude habitats (Zinsmeister and Feldmann, 1984).

Only six of the thirty-three valid genera of sea pens have previously been recorded from the Southern Oceans (Subantarctic and Antarctic regions). The discovery of a new genus, Gilibelemnon, and new species, Gilibelemnon octodentatum, of stachyptilid sea pen is here reported from the South Shetland Islands, which makes a total of eight genera known to occur in the Southern Oceans and thirty-four genera of sea pens known worldwide. Diagnostic features of the new genus are described, including the presence of a clearly delimited dorsal and ventral naked track on the rachis, the calyces with eight long terminal teeth, the siphonozooids densely and irregularly distributed and the presence of three-flanged rods in the peduncle surface. A discussion of sea pen phylogeny and biogeography in the Antarctic region is also provided.

Three new species of holothuroids from the Antarctic Peninsula and Bellingshausen Sea are described, with O’Loughin & Manjón-Cabeza as authors: dendrochirotids Cucumaria dudexa sp. nov., Psolicrux iuvenilesi sp. nov.; myriotrochid Myriotrochus hesperides sp. nov. Parathyonidium incertum Heding is discussed. Two synonymies for Antarctic holothuroids are formalised: Caespitugo citriformis Gutt is a junior synonym of Thyone scotiae Vaney; Caespitugo diversipes Gutt is a junior synonym of Cucumaria psolidiformis Vaney. Cucumaria armata Vaney is removed from inclusion in the Cucumaria georgiana (Lampert) group, and is a junior synonym of Cucumaria psolidiformis Vaney. A synonymy of Cucumaria aspera Vaney with Psolidium (Cucumaria) coatsi Vaney is rejected; Cucumaria aspera Vaney is referred to the Cucumaria georgiana (Lampert) group. Cucumaria conspicua Vaney is removed from synonymy with Psolidium (Cucumaria) coatsi Vaney, and is a junior synonym of Cucumaria psolidiformis Vaney. Thyone scotiae Vaney is referred to Crucella Gutt. Caespitugo Gutt is a junior synonym of Crucella Gutt. A new genus Cucamba O’Loughlin is erected; Cucumaria psolidiformis Vaney is referred to Cucamba O’Loughlin. A synonymy of Staurocucumis grandis (Vaney) with Staurocucumis turqueti (Vaney) is confirmed. The referral of Pseudocolochirus mollis Ludwig & Heding to Psolidiella Mortensen is confirmed. Lists of contemporary synonymies for Antarctic holothuroid species and generic referrals for Antarctic dendrochirotid species are provided. A table of holothuroid species collected from the Antarctic Peninsula and Bellingshausen Sea by the Spanish BENTART–2003 and BENTART–2006 cruises is provided.

The new genus and species Andeepia ingridae is described. The main features of this taxon are: urosomite 2 with middorsal tooth; massive propodi of gnathopods 1–2; carpus of gnathopod 1 short, weakly lobate and half the length of that of gnathopod 2; dactylus of gnathopod 2 with distinct dentition on the inner margin; dactylus of gnathopod 1 smooth, lacking dentition, but in the cuticle with faint trace of embedded teeth and reduced setation on pereopods and uropods. The related southern ocean pardaliscid, Nicippe unidentata K.H. Barnard, 1932 is also re-described and illustrated for the first time from the type material.

A new sponge genus and species, Astrotylus astrotylus, is described from the Antarctic abyssal zone. Its peculiar microscleres, herein referred to as astrotylostyles, combine the features of asterose spicules and tylostyles. Similar spicules are observed in Hymeraphia and Discorhabdella (order Poecilosclerida). But this similarity is convergent as far as a radial choanosomal skeleton composed by principal tylostyles and a cortical palisade of small tylostyles in Astrotylus undoubtedly confirm its allocation to the order Hadromerida and most likely to the family Polymastiidae. Atergia, Acanthopolymastia and Tylexocladus have the closest affinities with Astrotylus that calls for the phylogenetic analysis of their relations. Meanwhile astrotylostyles of Astrotylus, cladotylostyles of Tylexocladus and grapnel-like exotyles of Proteleia may be the remnants of non-monaxonic ancestral spicule type in Polymastiidae that calls for reconsideration of the relations between hadromerid families.

AbstractThe new genus and species Bicoloromyces kyffinensis is described as new to science from a sterile crustose lichen, perhaps Lecanora fuscobrunnea or Lecidella sp. from Ebony Ridge of Mount Kyffin, Antarctica. The fungus recalls superficially the lichenicolous species referred to Taeniolella, but differs in having semi-macronematous conidiophores, tissues encrusted with calcium oxalate, aeruginose to blue-black colouration under the microscope, and conidia which are distoseptate and formed in basipetal chains. Energy dispersive spectroscopy established that the encrustations were of calcium oxalate. Differences from genera of rock-inhabiting fungi described from the Antarctic are discussed. This appears to be the furthest south any lichen-inhabiting fungus has been reported.
