RV HNIMS Tydeman, 24 Aug 1986, fixed in 99.5% ethanol. Paratype: RMNH.COEL.42624, CANCAP-VII Expedition Station CV 7.041, Cape Verde Islands, SãoTiago, Ilheus Rombos, east of Cima, 14°56 ′ 59 ″ N, 24°37 ′ 59 ″ W, Agassiz trawl, at a depth of 580 m depth, coll. RV HNIMS Tydeman, 24 Aug 1986. Other material examined: RMNH.COEL.42625, Equalant II Expedition to the Gulf of Guinea, as part of the ICITA Programme (International Cooperative Investigations of the Tropical Atlantic), Sta. 18/8, 38 km off Liberia, 4°25 ′ N, 8°29 ′ W, trawl at a depth range of 380–510 m, on RV Geronimo Cruise 2, 31 Oct 1963, fixed in 99.5% ethanol. Etymology: This species is named in honour of Dr Jacob van der Land, expedition leader of the CANCAP-VII expedition off the coast of West Africa (Van der Land, 1987), during which the type specimens of this species were collected. The Japanese name is 'Hime-ruri-sunaginchaku'. Description: External morphology. Thirty-two cylindrical polyps in preserved specimen. Base of polyps embedded in Aphrocallistes sponge. Solitary polyps arise irregularly from host hexactinellid sponge. Preserved polyps cream white in coloration. Surface of column smooth, and ectoderm continuous. Ectoderm of polyps partially encrusted with small size of sand and silica particles. Transparent capitulum contracted and rounded. Contracted preserved polyps 0.3–2.5 mm in height, 0.8–3.0 mm in diameter. Capitulary ridges indiscernible when contracted. Approximately 20 tentacles in number. Internal morphology. Zooxanthellae absent. Cyclically transitional marginal musculature. Mesoglea thickness 0.2–1.1 mm. Mesoglea thicker than ectoderm and endoderm. Siphonoglyph distinct and V-shaped. Mesenterial filaments present. Cnidae. Basitrichs and microbasic b-mastigophores, microbasic p-mastigophores and spirocysts (Fig. 5C; Table 2). Distribution and habitats: West Africa: Guinea and Cape Verde at depths of 580– 800 m. Associated host: Aphrocallistes beatrix Gray, 1858, Aphrocallistes sp. Remarks: Vitrumanthus vanderlandi is phylogenetically close to V. oligomyarius, but these two species can be distinguished by dimensions of polyps and the numbers of tentacles. Vitrumanthus vanderlandi and V. oligomyaria are also associated with different host hexactinellid sponges (Aphrocallistes species vs. Tretochone duplicata). Moreover, V. vanderlandi does not have any holotrich nematocysts in all tissues we examined, while other species of Vitrumanthus have holotrich nematocysts present in some tissues. Although the in situ polyp colour of V. vanderlandi is unknown, Buhl-Mortensen et al. (2017) have reported yellowed zoantharians that were observed on A. beatrix collected from the Gulf of Guinea. Therefore, the coloration of polyps of this species may be yellow. Further investigations with newly collected specimens are needed to confirm the in situ morphology of V. vanderlandi.

KAULUZOANTHUS SP. (FIG. 9A���B) Material examined: USNM 1424050, French Frigate Shoals, Hawaii (23��56.649 ��� N, 166��02.187 ��� W), 1225 m, ROV, coll. RV Okeanos Explorer, NOAA on 28 February 2016, fixed in 99.5% EtOH. Description: Non-encrusted azooxanthellate zoantharians. The examined specimen associated with Hyalonema sp. Preserved polyps cylindrical and c. 1.8���9.6 mm in height, 3.9���6.7 mm in diameter, with brown column in coloration. Thin coenenchyme completely covering stalk of Hyalonema sp. Capitulary ridges discernible, 14���16 in number when contracted. Tentacles relatively short, as long as expanded oral disk diameter. Numbers of tentacles 28���32. Associated host: Hyalonema sp. Distribution and habitats: North Pacific Ocean: French Frigate Shoals, Hawaii, at a depth of 1225 m. Remarks: The genus Kauluzoanthus is known to associate with the gold coral Kulamanamana haumeaae and with several octocoral species (Sinniger et al., 2013). However, our examined specimen was associated with Hyalonema sponges, and was genetically close to Ka. kerbyi based on the results in this study. This finding suggests that Kauluzoanthus species are not host-specific to Ku. haumeaae or other octocorals. However, we could not obtain any 16S-rDNA sequences, which contain the V5 region sensu Sinniger et al. (2005). Therefore, further integrated studies including morphological and ecological studies are needed to describe this putative new species., Published as part of Kise, Hiroki, Montenegro, Javier, Santos, Maria E.

GENUS CHURABANA GEN. NOV. (FIG. 4A���H) Z o o b a n k r e g i s t r a t i o n: u r n: l s i d: z o o b a n k. org:act: EACFCC05-EA56-4F04-94A2-FB716F22004C. Type species: Churabana kuroshioae sp. nov. by original designation. Diagnosis: Parazoanthidae with obligate symbiotic relationship with massive hexasterophoran sponges. Preserved polyps 3.0���4.0 mm in height, 2.8���4.0 mm in diameter. Azooxanthellate. Cteniform endodermal marginal musculature. Remarks: Churabana and other already described sponge-associated zoantharian genera can be easily distinguished from each other by their host sponges (Hexactinellida sponges vs. Demospongiae sponge) and depths; the former can be found at> 140 m, while the latter are found in shallow coral reefs. Although Churabana and several species within Isozoanthus and Epizoanthus are associated with Hexactinellida sponges, these three genera can be distinguished from each other by their hosts: the latter two genera are associated with species within the subclass Amphidiscophora, while species of Churabana are associated with sponge species within the subclass Hexasterophora. Churabana has a unique deletion of 15 bp (from position 168 to 182 in our alignment) in its 16S-rDNA region. Etymology: The generic name is derived from the Ryukyuan language words chura, beautiful, and bana, flower, referring to the appearance of this species. Gender feminine. The Japanese name is 'Chura-tama-sunaginchaku'., Published as part of Kise, Hiroki, Montenegro, Javier, Santos, Maria E.

Ekins on RV Investigator, Cruise IN2017_V03, 3 June 2017, fixed in 99.5% EtOH. Description: External morphology. Circa 40 nearly saucer-shaped polyps connected by strongly developed dark-brownish coenenchyme on stalks of hexactinellid sponges (Hyalonema sp.) in preserved specimen. Colony covered the upper part of the stalks, but not around the spiculous anchor. Contracted preserved polyps only rise a little from the coenenchyme and flat, 0.4���1.1 mm in height, 3.0��� 6.9 mm in diameter. Capitulary ridges present and well pronounced when contracted, approximately 14���18 in number. Ectoderm and mesoglea of polyps and coenenchyme heavily encrusted with numerous sand and silica particles. Internal morphology. Zooxanthellae absent. Number of mesenteries 28���36, in macrocnemic arrangement. Mesogleal thickness c. 0.1���0.3 mm. Numerous and various size of pigment cells in the ectoderm and mesoglea. Mesoglea thicker than ectoderm and endoderm in column, actinopharynx and mesenteries. Reticulate mesogleal musculature short and poorly developed. Siphonoglyph distinct and V-shaped. Mesenterial filaments present. Habitat and distribution: Tasman Sea at depths of 1006���1036 m in this study. The type locality of this species is off Samboangan [Zamboanga City], Philippines at a depth of 150 m (82 fathoms). This species has been recorded from the Indian Ocean (Reimer & Sinniger, 2021), New Zealand (NIWA, 2018), the East Pacific Ocean (Beaulieu, 2001; Reimer & Sinniger, 2021) and the Caribbean Sea (Due��as & Puentes, 2018). Associated host: Hyalonema sp. Remarks: Epizoanthus stellaris can be distinguished from other Epizoanthus species found on stalks of hexactinellid sponges: the strongly lamellated polyps of E. stellaris are not observed in E. fatuus, E. armatus or E. longiceps (Lwowsky, 1913) (2.0���10.0 mm in height: Lwowsky, 1913; Carlgren, 1923). Lwowsky (1913) synonymized E. stellaris as E. fatuus on account of extreme growth forms of E. fatuus due to the high amounts of morphological variability that are commonly found within zoantharian species. However, the results of our molecular phylogenetic analyses support that E. stellaris and E. fatuus are distinct species. Beaulieu (2001) observed E. stellaris frequently in the East Pacific Ocean, although it should be noted that several species may be contained in E. stellaris, as observed by Beaulieu (2001), based on the results of the present study., Published as part of Kise, Hiroki, Montenegro, Javier, Santos, Maria E.

P r e s e r v e d p o l y p s 0.3–3.1 mm in length, 0.8–3.4 mm in diameter. Azooxanthellate. Cyclically transitional marginal musculature. Remarks: Vitrumanthus is distinguished from genus Churabana by its marginal musculature. In Vitrumanthus, cyclically transitional marginal musculature with several mesogleal lacunae was observed, while in Churabana cteniform endodermal marginal musculature with comb-like mesogleal pleats was seen. Molecular phylogenetic analyses clearly support the distinctiveness between Churabana and Vitrumanthus. In the 16S-rDNA region, Vitrumanthus has a unique deletion of 15 bp (positions 136–150 in our alignment). Etymology: The generic name is derived from the Latin word vitruma, glass, and Greek word anthos, flower, referring to the appearance of this genus. Gender masculine. The Japanese name is 'Ruri-sunaginchaku'.

Column of preserved polyps dark brown and light beige in coloration. Colonies covered upper part of stalks, but not around the spiculous anchor. Contracted preserved polyps 0.8���2.9 mm in height, 1.9���3.6 mm in diameter. Capitulum swollen, and diameter of capitulum larger than scapus when contracted. Capitulary ridges present and strongly pronounced when contracted, 14 in number. The number of tentacles of each polyp in this study 28, and tentacles arranged in two rows. Ectoderm and mesoglea of polyps and coenenchyme heavily encrusted with numerous sand and silica particles. Internal morphology: Zooxanthellae absent. Number of mesenteries 28, in macrocnemic arrangement. Mesogleal thickness 0.1���0.3 mm and gradually wider in direction from capitulum towards scapus. Mesoglea either as thick as or thinner than ectoderm. Reticulate mesogleal musculature. Siphonoglyph distinct and V-shaped. Mesenterial filaments present. Habitat and distribution: Indo-Pacific Ocean: near Indonesia (Carlgren, 1923), East China Sea (Pei 1998), the Bay of Bengal, India and Japan (Lwowsky, 1913). Associated host. Hyalonema spp. Remarks: This species has been reported in several studies, which indicate the presence of intraspecific variation (Andres, 1884; Lwowsky, 1913, Carlgren, 1923). In fact, we observed several morphological differences, such as coloration and polyp dimensions, between the two examined specimens (NSMT-Co 1757 and NSMT-Co 1758). Also, some genetic variation of E. fatuus was observed in ITS-rDNA sequences (8 bp), and thus the possibility remains that E. fatuus contains cryptic species, as ITS-rDNA has been demonstrated to be among the most variable genetic regions currently utilized to delineate species within Zoantharia (e.g. Reimer et al., 2007; Montenegro et al., 2015). However, the sequences of the two examined specimens formed a strongly supported monophyletic clade and we therefore identify the examined specimens as a single species in this study. Additional specimens and fine-scale genetic analyses are required to better examine if there is any cryptic diversity within this group., Published as part of Kise, Hiroki, Montenegro, Javier, Santos, Maria E.

Ekins on RV Investigator, Cruise IN2017_V03, 3 June 2017, fixed in 99.5% EtOH. Description: External morphology. Circa 40 cylindrical polyps connected by strongly developed light beige coenenchyme on stalks of hexactinellid sponges (Hyalonema sp.) in preserved specimen. Colony covered upper part of the stalks, but not around the spiculous anchor. Contracted preserved polyps 1.0���3.0 mm in height, 1.5���3.5 mm in diameter. Remarks: The capitulums of this specimen (QM G337590) were not swollen, while capitulums of the examined specimens of Epizoanthus fatuus (NSMT-Co 1757, NSMT-Co 1758) were swollen when contracted. On the other hand, numbers of tentacles and mesenteries were the same between QM G337590 and the examined specimens of E. fatuus. Therefore, we here preliminarily identify the examined specimen as Epizoanthus aff. fatuus., Published as part of Kise, Hiroki, Montenegro, Javier, Santos, Maria E.

EPIZOANTHUS AFF. ARMATUS CARLGREN, 1923 (FIG. 3E) Material examined: MISE-HPD1323 (NSMT-Co 1759), Kuroshima Island, Kagoshima, Japan, 24��13 ��� 36.1 ��� N, 124��06 ��� 18.0 ���E, depth 468 m, ROV, coll. J.D. Reimer on RV Natsushima, 19 Sep 2011, fixed in 90% ethanol. Description: External morphology. Circa 80 cylindrical polyps connected by strongly developed light-brownish coenenchyme on stalks of hexactinellid sponges (Hyalonema sp.) in preserved specimen. Colony covered the upper part of the stalks, but not around the spiculous anchor. Contracted preserved polyps well developed and 0.5���4.9 mm in height, 2.5���7.8 mm in diameter.Capitulary ridges present but weakly pronounced when contracted, c. 14���16 in number. The numbers of tentacles of each polyp c. 28���32 and tentacles arranged in two rows. Internal morphology. Zooxanthellae absent. Number of mesenteries 28���32, in macrocnemic arrangement. Reticulate mesogleal musculature. Habitat and distribution: Off Kuroshima, Okinawa, in the Ryukyu Archipelago, Japan at a depth of 468 m. Epizoanthus armatus has previously been reported from off Somalia in the Indian Ocean (Carlgren, 1923). Associated host: Hyalonema sp. Remarks: Polyp dimensions of the examined specimen are larger than those of E. fatuus and E. stellaris, and this specimen resembles E. armatus as described by Carlgren (1923). The morphological characters and dimensions observed in the examined specimen agree well with the original description by Carlgren (1923). Epizoanthus armatus was originally described from East Africa (Carlgren, 1923). Kise et al. (2018) reported the existence of E. planus Carlgren, 1923 in Japanese waters, and this species was also originally described from East Africa.Therefore, it is possible that E. armatus may also be distributed in Japanese waters. However, the collected depths of the examined specimen in this study and the specimens Carlgren (1923) examined are different (468 m vs. 741���1362 m deep). We also could not observe internal morphology of the examined specimen due to its poor preserved condition. Therefore, we here preliminarily identified the examined specimen as Epizoanthus aff. armatus. Examination of additional specimens combined with molecular analyses should help confirm the identity of this specimen. FAMILY PARAZOANTHIDAE DELAGE & HEROUARD, 1901 GENUS CHURABANA GEN. NOV.

Diagnosis: Parazoanthidae with obligate symbiotic relationship with massive hexasterophoran sponges. Preserved polyps 3.0���4.0 mm in height, 2.8���4.0 mm in diameter. Azooxanthellate. Cteniform endodermal marginal musculature. Remarks: Churabana and other already described sponge-associated zoantharian genera can be easily distinguished from each other by their host sponges (Hexactinellida sponges vs. Demospongiae sponge) and depths; the former can be found at> 140 m, while the latter are found in shallow coral reefs. Although Churabana and several species within Isozoanthus and Epizoanthus are associated with Hexactinellida sponges, these three genera can be distinguished from each other by their hosts: the latter two genera are associated with species within the subclass Amphidiscophora, while species of Churabana are associated with sponge species within the subclass Hexasterophora. Churabana has a unique deletion of 15 bp (from position 168 to 182 in our alignment) in its 16S-rDNA region. Etymology: The generic name is derived from the Ryukyuan language words chura, beautiful, and bana, flower, referring to the appearance of this species. Gender feminine.

Etymology: The species is named for Adriaan ���Dutch��� Schrier, owner of the manned submersible Curasub and RV Chapman, operated from Substation Cura��ao, for his generosity in allowing BWH to sample specimens. The Japanese name is 'Amime-ruri-sunaginchaku'. Description: External morphology. Circa 50 cylindrical polyps in preserved specimen. Solitary or colonial polyps rise irregularly from the hexactinellid sponge Verrucocoeloidea liberatoriii Reswig & Dohrmann, 2014. Living polyps white and tentacle transparent in coloration. Preserved polyps dark beige. Surface of column rough and ectoderm continuous. Ectoderm and mesoglea of polyps encrusted with numerous and various sizes of sand and silica particles. The living expanded oral disks c. up to 8.0 mm in diameter, expanded polyps c. up to 10 mm in height, 1.0���5.0 mm in diameter. Preserved contracted preserved polyps 0.3���2.1 mm in height, 0.8���2.8 mm in diameter. Capitulary ridges indiscernible. Tentacles 20���24 in number. Internal morphology. Zooxanthellae absent. Cyclically transitional marginal musculature. Encircling sinus present and basal canals of mesenteries absent. Mesenteries thin. Mesoglea thickness c. 0.6 mm. Mesoglea thicker than ectoderm and endoderm. Siphonoglyph distinct and V-shaped. Mesenterial filaments present. Cnidae. Basitrichs and microbasic b-mastigophores, microbasic p-mastigophores, holotrichs and spirocysts (Fig. 5B; Table 2). Distribution and habitats: Caribbean Netherlands: known from Cura��ao and Bonaire at depths of 140��� 248 m. Associated hosts: Verrucocoeloidea liberatorii Reswig & Dohrmann, 2014, Parahigginsia strongylifera Van Soest, Meesters & Becking, 2014 and Cyrtaulon sigsbeei (Schmidt, 1880). Remarks: In terms of host hexactinellid sponges, Vitrumanthus schrieri can be distinguished from V. vanderlandi and V. oligomyarius (Wassilieff, 1908) because only V. schrieri is associated with Verrucocoeloidea sponges. Vitrumanthus schrieri is not only associated with hexactinellid sponges, but also with Demospongiae species in the genus Parahigginsia (Van Soest et al., 2014). On the other hand, V. vanderlandi and V. oligomyarius are associated with Tretochone duplicata (Topsent, 1928). In addition, the column of V. schrieri is rough, due to heavy encrustation, while columns of V. vanderlandi and V. oligomyarius are smooth with almost no encrustations. Vitrumanthus sp. (NSMT-Co 1755) and V. vanderlandi are associated with Cyrtaulon species. Reiswig & Dohrmann (2014) reported zoantharians were found on Verrucocoeloidea liberatorii, and we judge that these are likely V. schrieri based on external morphology and the host hexactinellid sponge species., Published as part of Kise, Hiroki, Montenegro, Javier, Santos, Maria E.

As tromboses são eventos de etiopatogênese multifatorial resultantes da interação de fatores genéticos e ambientais, constituindo na atualidade uma das causas mais comuns de morbimortalidade. Uma mutação de ponto no fator V da coagulação, o fator V Leiden (FVL), constitui o defeito genético mais comum associado com trombofilia. No Brasil, o estudo deste fator de risco é relativamente recente e se dispõe de poucos dados na literatura especializada. Este trabalho teve como objetivo determinar a freqüência da mutação do fator V Leiden em 292 indivíduos sob investigação de trombofilia no Hemocentro de Pernambuco. A técnica molecular utilizada foi a RE/PCR (Enzima de Restrição/Reação em Cadeia da Polimerase), usando primers específicos e a enzima MnlI. A freqüência do FVL encontrada foi de 13,3%, sendo 36 heterozigotos e 3 homozigotos. A presença da mutação foi semelhante em indivíduos com idade tanto inferior quanto superior a 45 anos. Os resultados da pesquisa mostraram que a freqüência do FVL na população estudada é semelhante à descrita na literatura científica para indivíduos selecionados com tromboembolismo e confirmam a importância do estudo molecular nas diferentes faixas etárias. Thrombosis is a multifactorial disease involving genetic and environmental factors and constitutes one of the most common causes of morbimortality. A point mutation in coagulation factor V - factor V Leiden (FVL), constitutes the most prevalent genetic defect associated with thrombophilias. The study of this risk factor is relatively recent in Brazil and only a few reports have been published to date. The aim of this study was to determine the frequency of FVL in 292 individuals being investigated for thrombophilia at the Pernambuco State Blood Center. The molecular biology technique used was RE/PCR (Restriction Enzyme / Polymerase Chain Reaction), using specific primers and the MnlI enzyme. The frequency of FVL was 13.3% including 36 heterozygous and 3 homozygous individuals. The presence of the mutation was similar among individuals under and over 45 years old. Our findings are similar to results published for selected patients who suffered from thromboembolism and they confirm the importance of molecular testing at different ages.
