It is with regret that the Society announces that the publication of Volume 134 in 2021 of its flagship journal, the Proceedings of the Biological Society of Washington, will mark the final issue of the journal. The Society was founded in 1880 and began formal publication of its Proceedings in 1882 [for a detailed account of the first 100 years of the Society, see Aldrich, J. W. (1980) The Biological Society of Washington: A Centennial History 1880–1980. Bulletin of the Biological Society of Washington, No. 4, 40 pp.]. In its 141-year tenure, the Proceedings published thousands of articles that documented the taxonomy and systematics of global biodiversity, especially in the disciplines of Botany, Paleontology, and Zoology. All of the Proceedings’ articles can be accessed through the Biodiversity Heritage Library (1882–2004) or BioOne (2005–2021). The Society takes great pride in the quality of presentation and the diversity of taxa covered in the Proceedings’ articles throughout the years of its publication. The legacy of the journal is grounded in the fact that its many articles will be cited by researchers for decades to follow. It is appropriate at this time, to thank the many individuals who served as Officers of the Society throughout its history. The Editors and Associate Editors of the Proceedings deserve equal recognition. Without the dedication of all of these individuals, the Society and its journal could not have flourished. Also, thanks must be extended to all of the individuals who were members of the Society through its many years, whose support was vital to the health of the Society. Finally, to all of the individuals who authored articles published in the Proceedings, thank you for using our journal as an outlet for your valuable research results.
该学会遗憾地宣布，其旗舰期刊《华盛顿生物学会学报》(Proceedings of the Biological Society of Washington)将于2021年出版第134卷，这将标志着该期刊的最后一期。该学会成立于1880年，并于1882年开始正式出版其会刊[关于学会前100年的详细记录，见Aldrich, J. W.(1980)华盛顿生物学会:1880 - 1980年百年历史]。华盛顿生物学会公报，第4期，40页。在其141年的任期内，《论文集》发表了数千篇文章，记录了全球生物多样性的分类学和系统学，特别是在植物学、古生物学和动物学领域。所有论文均可通过生物多样性遗产图书馆(1882-2004)或BioOne(2005-2021)获取。学会对其出版多年来发表的论文所涵盖的分类群的质量和多样性感到非常自豪。该杂志的遗产基于这样一个事实，即它的许多文章将在接下来的几十年里被研究人员引用。在这个时候，感谢在整个协会历史上担任官员的许多个人是恰当的。《论文集》的编辑和副编辑应得到同等的承认。没有这些人的奉献，学会和它的期刊不可能蓬勃发展。此外，还必须感谢多年来一直是协会会员的所有个人，他们的支持对协会的健康至关重要。最后，感谢所有在《论文集》上发表文章的个人，感谢你们使用我们的期刊作为发表宝贵研究成果的渠道。

Abstract. We describe three new species of frogs in the asterophryine microhylid genus Cophixalus from New Guinea's central cordillera. All three are characterized by their very small size (adult body length < 18 mm), reduced first fingers, narrow ridges on the dorsum, and having terminal discs on the fingers smaller than or the same size as those on the toes. They were found on the forest floor or on low vegetation in montane rainforest, where males called at night during or after heavy rain. Each of the new species is known only from one or two locations within a small area of central Papua New Guinea, although the extent of suitable habitat in the region suggests that their distributions may be broader. This study brings to 51 the number of described Cophixalus species known from the New Guinea region, but numerous additional undescribed forms reside in museum collections awaiting formal description, and others undoubtedly await discovery in their natural habitats.

Abstract. In the current study, scleractinian corals from the Albian (uppermost Lower Cretaceous; 112.6–99.7 Ma) including 337 species (280 taxa assigned to species; 57 taxa kept in open nomenclature) from 147 genera (six of which include subgenera) belonging to 42 families (two of which include subfamilies; and incertae sedis) are evaluated and revised. Two new species (Apoplacophyllia asiatica, new species and Trigerastraea sikharulidzeae, new species) are described and two lectotypes are designated. Some specimens are illustrated for the first time, and new material (from Austria) is presented. The coral material includes records from 30 regions in Africa, the Americas, the Arctic, Asia, Australasia, and Europe. The most extensive records of Albian corals are from tropical/subtropical and arid areas, including the U.S.A., Mexico, Greece, France, and Spain. Over three-quarters of the Albian taxa belong to morphological forms having little to no hermatypic character (sensu Coates & Oliver), including species of the cerioid-plocoid group (genera: 36.7%; species: 38.5%), solitary taxa (genera: 26.5%; species: 28%), and branching forms (genera: 26.5%; 39 species = 11.5%). The coral faunas of the Albian are dominated by corals of “modern” microstructural groups sensu Roniewicz & Morycowa (76 genera = 51.7%; 169 species = 50.1%). Compared to the lowermost Cretaceous (Berriasian), which showed that 91% of the species and 83% of the genera belonged to previously established microstructural groups, the Lower Cretaceous ends with “modern” groups having become dominant. During the lower and middle Albian, the vast majority of taxa belonged to colonial forms (both 74%). A shift took place during the upper Albian, significantly increasing the number of solitary species to over 40% of the Albian fauna (42.9%). Throughout the Albian, the most diverse coral assemblages include non-reefal faunas, suggesting that, in contrast to, e.g., the Barremian–Aptian time period, reefal developments were less crucial for coral recruitment during this time. This study of the Albian fauna was used as the basis for synthesizing classical taxonomic works with modern microstructural data and recent DNA analyses in order to propose both a modified taxonomic framework and a working hypothetical phylogenetic tree for 41 scleractinian families occurring in the fossil record.

Abstract. Six species of bopyrids were detected by inspection of crustaceans of diverse taxa collected in the Gulf of Mexico and the Mexican Caribbean that were deposited in two scientific collections housed in the Universidad Nacional Autónoma de México. Probynia ramiroromani, new species is described, becoming the first species of the genus from the American continent. The occurrence of Pseudione cf. crenulata is recorded for the first time in the west Atlantic coast, the distribution ranges of Orthione furcata, Parabopyrella thomasi, and Robinione overstreeti are extended, and O. furcata and Urobopyrus processae are reported for the first time in Mexican waters. Munida valida, Periclimenaeus perlatus, Processa bermudensis, and Upogebia vasquezi are now recognized as hosts of P. cf. crenulata, P. ramiroromani, U. processae, and O. furcata, respectively.

Abstract. Green anoles of the Anolis carolinensis Voigt, 1832 species group have been become successfully established by human transport on many islands in the Pacific, from Okinawa in the west to Hawaii in the east. First recorded from Oahu in 1950, from the time of their discovery, and for decades afterwards, the green anoles of the Pacific were identified as the Cuban green anole, Anolis porcatus. We show that Pacific green anoles are readily distinguished from A. porcatus by the larger head scales of A. porcatus but are essentially indistinguishable from A. carolinensis from South Carolina, which come from within the range of the same mtDNA clade as the source of the Pacific invasion in Texas and Louisiana. Genetically distinct A. carolinensis from southern Florida are intermediate in scale size, differing in this respect from Pacific green anoles. These results are in harmony with recent molecular genetic studies on the phylogeny and status of green anoles from the Pacific, North America, and Cuba. The green anole of the Pacific is A. carolinensis sensu stricto.

Abstract. We herein describe a new species of stylochoplanid flatworm, Alloioplana yerii, from Japan. This is the first record of the genus from the West Pacific. Alloioplana yerii is characterized by i) a lack of nuchal tentacles, ii) an oval prostatic vesicle that is smaller than the seminal vesicle, iii) the presence of a common sperm duct, and iv) the presence of an intra-prostatic ejaculatory duct. We provide a partial sequence of the mitochondrial cytochrome c oxidase subunit I (COI) gene (712 bp) as a DNA barcode for the species. Our phylogenetic analyses based on concatenated sequences of 18S and 28S ribosomal DNA and of COI suggest that Stylochoplanidae is not monophyletic and that Al. yerii forms a relatively well-supported clade with Echinoplana celerrima Haswell, 1907 (Gnesiocerotidae) and Notoplana sp. (Notoplanidae).

Abstract. Three new species of Microspio were found in collections from a range of depths including shallow water in Bermuda, the continental shelf off Massachusetts, and deep water in the South China Sea off Brunei. Microspio fischeri, new species, is associated with shallow water sponges in Bermuda where it is a prey species of a predatory syllid; it is characterized by the medial placement of the first pair of branchiae as well as unusual notopodial capillaries in anterior chaetigers and enlarged notopodial lobes in posterior chaetigers. Microspio lydonia, new species, from the continental shelf on the east coast of the United States is distinguished from M. pigmentata (Reish, 1959) from the west coast by differences in the structure of the nuchal organs and hooded hooks, pigmentation, and Methyl Green staining patterns. Additions to the description of M. pigmentata include illustration of the nuchal organs and dorsal ciliary bands. Microspio ariena, new species, from deep water in the South China Sea off Brunei has enlarged branchiae with large glands that stain deeply with Methyl Green on a few anterior chaetigers, followed by much smaller branchiae on additional chaetigers. The three new species bring the total of described species in the genus to twenty-one, although some species remain problematic. A table comparing important characteristics of all 21 known species of Microspio is included.

Abstract. All species in the epicaridean isopod genus Zonophryxus Richardson, 1903 are reviewed, and information regarding host choice is summarized. The enigmatic species Colypurus agassizi Richardson, 1905 is shown to be synonymous with Zonophryxus similis Searle, 1914, and Colypurus Richardson, 1905 and Colypuridae Richardson, 1905 are synonymized with Zonophryxus and Dajidae, respectively. The correct name for the species is Zonophryxus agassizi, new combination. The existence of two distinct male morphotypes in at least some species of Zonophryxus is confirmed and discussed. Type and other material of Zonophryxus retrodens Richardson, 1903 and Zonophryxus trilobus Richardson, 1910 were examined, and these species are discussed and illustrated, including description of morphological structures either erroneously or not previously reported. New material of Zonophryxus dodecapus Holthuis, 1949 is reported on, with the discovery that females of the species can have either five or six pairs of pereopods independent of their developmental stage. A new species, Zonophryxus probisowa, is described from Peruvian material and named in honor of The Proceedings of the Biological Society of Washington on the occasion of this, its final volume.

A new species, Zonophryxus probisowa, is described from Peruvian material and named in honor of The Proceedings of the Biological Society of Washington on the occasion of this, its final volume.","PeriodicalId":54578,"journal":{"name":"Proceedings of the Biological Society of Washington","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2021-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45568213","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}

Abstract. A new species of Magelona is described based on collections from off Long Island, New York that are identical to an undescribed species reported by M. L. Jones (1968) from the vicinity of Woods Hole, Massachusetts. The species is herein named (M. brachypalpata, new species) and described. The new species belongs to the ‘Magelona mirabilis group,’ possessing a rounded prostomium, lacking prostomial horns, and having specialized chaetae on chaetiger nine. The new species is most similar to M. riojai and M. sacculata, both of which are here redescribed. Additionally, a dichotomous identification key to the known magelonid species of the northeastern American coast and a worldwide pictorial identification key to the ‘M. mirabilis’ group of magelonids are provided.
