Based on collections of interstitial Syllidae (Annelida) from several areas of the Indo-Pacific Ocean (Madagascar, Andaman Islands, South China, Hong-Kong, the Philippines, and New Zealand), we report a total of 49 species belonging to 19 genera. Most of these species are already known in the Indo-Pacific area, but these reports extend their distributional ranges. Nine species are described as new: Parexogone javieri (from New Zealand), Parexogone viejoi (from the Philippines), Prosphaerosyllis fittoni, Sphaerosyllis dieteri, Syllis kai, Perkinsyllis tsilo (from Madagascar), and Megasyllis chiki, Syllis dominguezi, and Syllis escribanoi (from China). Two species, previously described as Streptosyllis Webster & Benedict, 1884 are transferred to the genus Streptospinigera Kudenov, 1983: S. baolingi (Ding & Westheide, 1994), new combination, and S. hainanensis (Ding & Westheide, 1994), new combination, both from China. One species is transferred to Syllis [Typosyllis botosaneanui (Hartmann-Schröder, 1973)], new combination.","PeriodicalId":54578,"journal":{"name":"Proceedings of the Biological Society of Washington","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2021-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46147313","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}

A new species of Lepidodermella (Gastrotricha: Chaetonotida: Chaetonotidae) is described from two streams in northwestern Oregon, U.S.A. This is the fourth species of freshwater gastrotrich reported from the Pacific Northwest region of the United States. The dearth of reports appears to be due more to a lack of study rather than a lack of gastrotrichs. Lepidodermella squamata is one of the species already reported from the Pacific Northwest, and occurs sympatrically with the new species described here. No other members of the genus have been reported from the Pacific Northwest. Three species of Lepidodermella have been reported previously from North America. The genus includes one marine species and 14 freshwater species. Lepidodermella weissi, new species, brings the number of freshwater species to 15 and can be distinguished from other freshwater members of the genus by the following characters: absence of parafurcal spines, absence of transverse anterior ventral plates, head width of less than 40 µm, head with five lobes, pharynx length 44 µm or less, adhesive tube length of 5 µm or more, more than 35 scales per middorsal column, presence of seven or fewer posterior midventral columns of scales, presence of a pair of posterior ventral plates, and the presence of several columns of spined scales between the ventral ciliary bands and the smooth scales of dorsum and sides.","PeriodicalId":54578,"journal":{"name":"Proceedings of the Biological Society of Washington","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2021-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45732060","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}

The gastropod family Strombidae has sparked the recent interest of taxonomists as early revisions of the family are re-examined, with a plethora of new species and genera being described. This has brought a greater understanding of the level of diversity within the family, which has assisted in conceptualizing its evolutionary intergeneric relationships. However, gaps in the revisions remain. This paper examines the extant members of the genus Gibberulus after half a century of neglect. After examination of type material and original descriptions, the species are recircumscribed, and a new species, G. dekkersi, new species, is presented, bringing the total number of species in the genus to four. In addition, information of the geographic range of each species is provided. We suggest that, as further revisions of the Strombidae are conducted, particularly of those species with large fragmented distributions, a greater diversity of species will be found and described.","PeriodicalId":54578,"journal":{"name":"Proceedings of the Biological Society of Washington","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2021-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46731739","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}

New species of the until now monotypic buccinoidean genera Germonea and Drepanodontus are described from the southwestern Atlantic waters. These genera are only otherwise known from lower bathyal and abyssal depths of Scotia Sea. Germonea costulosa n. sp. collected near Namuncurá/Burdwood Bank in 681 to 785 m depth is the second known species of the genus characterized by distinctive regular ribs. In addition, Drepanodontus peonza n. sp., collected from the same area, is similar to the type species of this genus with two distinctive spiral cords along all whorls. The bathymetry of both new species is shallower than that of the already described species, at upper slope depths. Geographically the new species put both genera on both sides of the Antarctic convergence. Previous reports include D. tatyanae sharing this distribution rising some questions about the effectiveness of the Drake passage as a barrier.","PeriodicalId":54578,"journal":{"name":"Proceedings of the Biological Society of Washington","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49188342","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}

Wilson","doi":"10.2988/006-324X-134.1.42","DOIUrl":"https://doi.org/10.2988/006-324X-134.1.42","url":null,"abstract":"Abstract. The skull morphology of four species of cottontails from the mountains and plateaus of southwestern United States and northern Mexico, currently recognized as Sylvilagus nuttallii, S. cognatus, S. robustus, and S. holzneri (=S. floridanus holzneri), was analyzed using multivariate statistics. Based on 26 or 30 measurements taken on each of 350 adult skulls, and formulation of 16 pooled samples, with each representing a different geographic population, the results show there are two species-level distinctions in skull type. Cottontails from southern Utah, northern and east-central Arizona, and northern New Mexico show morphological overlap among geographically adjacent samples and all have a highly arched skull. These are referable to S. nuttallii. Cottontails from central Arizona, central New Mexico, and western Texas southward along the Sierra Madre Occidental to Durango, Mexico, and Sierra Madre Oriental to central Coahuila, Mexico show morphological overlap among geographically adjacent samples and all have a relatively flat skull. These are referable to S. holzneri. Both S. nuttallii and S. holzneri are polytypic in the study area. Sylvilagus n. pinetis is restricted to the White Mountains of Arizona. Those north and west of the Colorado River in Arizona and Utah are referable to S. n. nuttallii and those from southeastern Utah, northeastern Arizona and northern New Mexico are referable to S. n. grangeri. The population of cottontails previously referred to S. cognatus from central New Mexico is indistinguishable from topotypical S. holzneri from southeastern Arizona as well as populations from southwestern New Mexico, Chihuahua, and Sonora, Mexico. Cottontails previously referred to S. robustus, from the Guadalupe Mountains of New Mexico and Texas, southward in the mountains of western Texas, and the Sierra Madre Oriental to central Coahuila, Mexico, average larger in overall size and, on average, have proportionately larger auditory bullae and are referable to S. holzneri robustus. The relationship of S. holzneri to other mountain/plateau-inhabiting taxa, outside the study area in central and southern Mexico remains to be resolved.","PeriodicalId":54578,"journal":{"name":"Proceedings of the Biological Society of Washington","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2021-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44724748","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}
