{"title":"Bryozoa (Cheilostomata) from polymetallic nodules in the Russian exploration area, Clarion–Clipperton Fracture Zone, eastern Pacific Ocean—taxon novelty and characteristics as macro- and megafaunal elements","authors":"A. V. Grischenko, Dennis P. Gordon, V. P. Melnik","doi":"10.11646/zootaxa.5440.1.1","DOIUrl":"https://doi.org/10.11646/zootaxa.5440.1.1","url":null,"abstract":"This work describes Bryozoa of the order Cheilostomata associated with polymetallic nodules collected by box-coring in the eastern part of the Russian exploration area of the Clarion-Clipperton Fracture Zone (CCFZ or CCZ) under contract to Yuzhmorgeologiya. Study of 569 cheilostome specimens from 4510–5280 m depth yielded 32 species (22 new) in 20 genera (3 new) and 14 families (1 new). For six species, the nomenclature was left open (genus only) owing to the paucity of defining characters. One species with a costate frontal shield, possibly belonging to the otherwise monotypic Polliciporidae, clearly represents a new genus, but was not named, as it comprises only an ancestrula, one fully formed daughter zooid and a zooid bud. Four of the species we detected are known from the deep sea beyond the CCZ; Columnella magna and Acanthodesiomorpha problematica occur not only elsewhere in the Pacific Ocean but also the Atlantic Ocean, while Smithsonius quadratus was first described from the Kuril-Kamchatka Trench, and the authors have unpublished records of Smithsonius candelabrum n. sp. from the Magellan Seamounts and the Louisville Ridge. These records give hope that other CCZ bryozoan taxa may also occur elsewhere, offsetting local extirpation through nodule mining. Almost 63% (20 species) of CCZ Cheilostomata have a flexibly erect colony attached by one or several rhizoids (and/or the ancestrula has a proximal cuticular stalk-like portion). Ten other species have fixed-erect rigid colonies; only two species are encrusting. If a 50 mm height or spread is taken as the lower limit defining a megafaunal organism, then only C. magna qualifies as megafaunal. If 20 mm is taken as the lower size limit (definitions vary), then nine other species have the potential to be recognized in ROV-obtained images. The completion of this monograph allows a summary of all bryozoan data for the Russian sector of the CCZ. Altogether, 52 species are known from this area, totalling 1002 specimens from 437 stations. The most abundant and most ubiquitous species was the cyclostome Pandanipora helix, comprising 230 specimens from 137 stations and accounting for almost 23% of all specimens collected. The next most abundant and ubiquitous species were the cheilostomes Aulopocella polymorpha (124 specimens, 105 stations) and Fulgurella marina (104 specimens, 92 stations). These three species accounted for almost 46% of all specimens collected. All other species yielded fewer than 45 specimens each from 33 or fewer stations. Twelve species were represented by a single colony. Although some ROV images from eastern sectors of the CCZ have been recognized as bryozoans and published as such, few have been studied systematically. Bryozoans have also been reported from seamounts, level-bottom rock flats, ridges and troughs in the CCZ, but their identities remain unknown. It is imperative that institutions seek the collaboration of taxonomists rather than allow material to languish uniden","PeriodicalId":24072,"journal":{"name":"Zootaxa","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140688120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, we propose D. kiefferi Benoit syn. nov. as a junior synonym of D. matticus and D. orophilus Benoit syn. nov. as a junior synonym of D. adscitus.

The differentiation between the genus Trichophallus and the superficially similar genera Subria Stål, 1874, Secsiva Walker, 1869, and Subrioides C. Willemse, 1966 are outlined and discussed. Important characters to differentiate Trichophallus from other similar genera are found in a combination of the shape of the fore wings, the absence of prosternal spines, and the male titillators being provided with tufts of hairs apart from sclerites. The female ovipositor carries a pair of sub-basal, lateral lobes, so far unknown from other genera of Tettigoniidae, and the female subgenital plate is provided with a pair of basal, dorsal-lateral extensions often larger than the ventral area of the subgenital plate. 19 species and one subspecies are described as new, all from New Guinea or nearby islands.

Presently, it is considered to contain about 2,650 valid species, divided into nearly 102 genera of three subfamilies: Amblyseiinae, Phytoseiinae and Typhlodrominae. Approximately 250 of those have been reported from Brazil. Amblyseiinae is the largest subfamily, with about 65% of the described species. This publication summarises the morphologic, taxonomic and distributional information of the Amblyseiinae reported from Brazil, in support of future research on their conservation and practical use. A total of 195 valid species of 29 genera of Amblyseiinae is listed in this publication, 121 of which were described from this country, including seven species which are most certainly incorrect reports, based on the present state of knowledge. Two new combinations are proposed: one in Amblyseius, Amblyseius malvus (Denmark & Evans), and one in Transeius, Transeius piracicabae (Denmark & Muma). Six new synonyms are proposed (Chelaseius lativentris Karg, T. piracicabae, Euseius errabundus De Leon, Typhloromalus clavicus Denmark & Muma, Typhlodromips fordycei (De Leon) and Typhlodromips mangleae De Leon, as senior synonyms of Chelaseius brazilensis Denmark & Kolodochka, Transeius gervasioi Rocha, Silva & Ferla, Euseius plaudus Denmark & Muma, Typhlodromalus simus Denmark & Muma, Typhlodromips igapo Nuvoloni, Lofego, Rezende & Feres and Typhlodromips pederosus El-Banhawy, respectively). A key is provided to help in the separation of the species reported. So far, the most diverse genera in Brazil (followed by the number of species reported) are: Amblyseius Berlese (48), Neoseiulus Hughes (23), Typhlodromips De Leon (22), Iphiseiodes De Leon (14), Amblydromalus Chant & McMurtry (13) and Euseius Wainstein (12). The highest number of species is reported from the southeastern region (119 species), followed by the northeastern (82), the northern (68), the southern (65) and the midwestern (52). The states with highest numbers of registered species are São Paulo (109), Bahia (70), Rio Grande do Sul (62), Amazonas (47), Pernambuco (44) and Minas Gerais (43), while those with lowest numbers are Rio Grande do Norte (16), Sergipe (12), Pará (12), Rondônia (7) and Amapá (5).

All potential morphological features were considered, with 364 adult characters surveyed. Of these 146 adult characters were considered informative and these were combined with 40 pupal features previously interpreted by Borkent (2014), 16 larval and two egg characters. The resulting phylogeny confirmed the relationships between the early lineages including Leptoconopinae, Forcipomyiinae and Culicoidini (other than Washingtonhelea) previously interpreted. The remainder are Ceratopogoninae and these are divided into 11 tribes of which four are new: Washingtonheleini, Parabezziini, Neurobezziini and Echinoheleini. The last three were previously considered as members of the Ceratopogonini. Remaining Ceratopogonini are still recognized as a paraphyletic group, with some lineages poorly resolved phylogenetically. Some genera are realigned within the tribes Sphaeromiini, Johannsenomyiini and Palpomyiini. Poorly understood genera are discussed in some detail. \u0000 Available autapomorphies of genera are presented, showing that some genera lack evidence of monophyly.
