During 2007, 2008, and 2010, 23 specimens of an undescribed vermiform sea anemone were collected on Punta Pardelas and Fracaso Beach (Península Valdés, Argentina). The specimens have longitudinal rows of cinclides distally, all mesenteries perfect, tentacles hexamerously arranged without acrospheres, column not divisible into regions, no marginal sphincter and no conchula. We describe these specimens as a new species within the genus Harenactis (family Haloclavidae). Harenactis argentina sp. nov. is the second species of Harenactis; it represents the first record of this genus in the southern hemisphere and the first record of a soft bottom-dwelling sea anemone in the Argentine continental zone. Furthermore, we discuss the familial placement and relationships of the genus Harenactis and other athenarian sea anemones.

Zatypota albicoxa (Walker) is newly recorded from Mt. Merapi, Java Is., Indonesia. This is the first record of Z. albicoxa from this part of the Oriental region and from the Southern Hemisphere, and the first record of the genus Zatypota from Southeast Asia. The Indonesian population of Z. albicoxa attacks a theridiid spider of the genus Parasteatoda, as do populations of Z. albicoxa in other regions. The spider is a new species, and is described under the name of Parasteatoda merapiensis.

Psychrolutes sio, a new species of Psychrolutidae from off northernmost Chile, is described from two specimens trawled at about 770–1150 m. The holotype is deposited in the Scripps Institution of Oceanography (SIO 72-184). The only large specimen, the 22.9-cm holotype, differs most conspicuously from the other two species of the genus Psychrolutes in having the head and body color a uniform brown, skin thin, lateral line pores in small but distinct tubes, and jaws equal. Psychrolutes sio represents the first record of the genus Psychrolutes to be recognized from the Southern Hemisphere. However, future studies may indicate that other southern psychrolutids of the genera Neophrynichthys and Cottunculoides should also be assigned to Psychrolutes.

Victoriopisa bantenensis sp. nov. has not been previously reported and also the first record of the genus in Indonesian waters. It was collected from soft-bottom subtidal sediment in Banten Bay, West Java, Indonesia and is one of two Victoriopisa which has a notch on the anteroventral margin of the head. Victoriopisa bantenensis is characterized by the absence of eyes, the lateral cephalic lobes elongate and the absence of excavation on the gnathopod 2 propodus palm. Male and female of Victoriopisa bantenensis sp. nov shows sexually dimorphic characters on gnathopods 2. Male gnathopod 2 propodus palm without excavation while female with one excavation. Previously, 13 species of Victoriopisa has been described, and this one is the 14 species of the genus.

A new genus and a new species, Haplodendron buzwilsoni, from the southeastern Australian mid bathyal are described. This is the first record of the family in the Southern Hemisphere IndoPacific. Diagnostic characters of the new genus are compared with those of other genera in the family. The possible significance of the joint possession, between the new genus and Dendrotion (Dendrotiidae), of a stalk carrying the antennulae and antennae is discussed. New observations on male reproductive structures are made.

The crustacean order Thermosbaenacea is reported for the first time from the Southern Hemisphere, from almost fresh water in a cave habitat in tropical Western Australia. Halosbaena tulki, sp. nov. belongs to a genus previously known only from saline waters in the West Indies, Columbia and Canary Is. The discovery is consistent with a very ancient origin of the order and distribution of the genus by plate movements following the breakup of Pangaea.

Four species of Phlyctaenopora Topsent, 1904 (Demospongiae Sollas, Poecilosclerida Topsent, Mycalidae Lundbeck) are recognised today (Van Soest et al. 2021a) (Table 1): two Atlantic Ocean species in subgenus Phlyctaenopora [type species P. (P.) bitorquis Topsent, 1904, from the Azores; P. (P.) halichondrioides van Soest & Stentoft, 1988, from Barbados]; and two Southern Hemisphere species in subgenus Barbozia Dendy, 1922: P. (Barbozia) primitiva Dendy, 1922, from the Seychelles, and P. (B.) bocagei Lévi & Lévi, 1983, from New Caledonia. Here we describe a new species of Phlyctaenopora from Wanganella North in International Waters on the West Norfolk Ridge, northwest of New Zealand. Phlyctaenopora (B.) spina sp. nov. provides a first record of the genus in the South Pacific, providing further confirmation of the integrity of the subgenus Barbozia.

Pseudarachna nohinohi n. sp. from the Challenger Plateau, New Zealand is described. A further two undescribed species are recorded from Australian waters in the Tasman Sea, showing that this formerly monotypic North Atlantic genus is more widely distributed than previously thought. A revised diagnosis of the genus is presented.

AbstractThe order Intejocerida is an enigmatic, short-lived cephalopod taxon known previously only from Early–Middle Ordovician beds of Siberia and the United States. Here we report a new genus, Cabaneroceras, and a new species, C. aznari, from Middle Ordovician strata of central Spain. This finding widens the paleogeographic range of the order toward high-paleolatitudinal areas of peri-Gondwana. A curved conch, characteristic for the new genus, was previously unknown from members of the Intejocerida.UUID: http://zoobank.org/21f0a09c-5265-4d29-824b-6b105d36b791
