Three new tiny species of the microhylid frog genus Cophixalus Boettger, 1892 from central Papua New Guinea Proc. Biol. Soc. Wash. (IF 0.5) Pub Date : 2021-11-17 Rainer Günther, Stephen Richards
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

An iconography of extant Gibberulus Jousseaume, 1888 (Mollusca, Gastropoda, Strombidae), and the introduction of a new species from the southwestern Pacific Proc. Biol. Soc. Wash. (IF 0.5) Pub Date : 2021-07-21 Stephen J. Maxwell, Linda C. Hernandez Duran, Misha K. Rowell, Tasmin L. Rymer
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

U-Th dating of Holocene age Acropora prolifera (Lamarck, 1816) colonies confirms coral hybridization is not a recent phenomenon. Proc. Biol. Soc. Wash. (IF 0.5) Pub Date : 2020-09-21 Alexander B. Modys, Richard A. Mortlock, Stephen V. Vollmer, Les Kaufman, William F. Precht
To confirm previous findings that hybridization of Caribbean acroporid corals occurred in the recent geologic past, we determined the uranium-thorium (U-Th) ages of two subfossil Acropora prolifera samples collected from nearshore coral death assemblages located off the coast of southeastern Florida. Our results indicate that A, prolifera existed in southeastern Florida during the late Holocene, confirming

Fossil Acropora prolifera (Lamarck, 1816) reveals coral hybridization is not only a recent phenomenon Proc. Biol. Soc. Wash. (IF 0.5) Pub Date : 2019-04-17 William F. Precht, Stephen V. Vollmer, Alexander B. Modys, Les Kaufman
Abstract. Acropora prolifera is an ecologically distinctive western Atlantic reef-building coral that originates from hybridization and back-crossing between A. palmata and A. cervicornis. It has been suggested that A. prolifera might be a recent product of precipitous decline in the abundance of the two parent species, forcing hybridization where both it and its product might not otherwise be prevalent

New records of Microlepidoptera (Insecta: Lepidoptera) from Plummers Island, Maryland, U.S.A., with comments on Lepidoptera inventories Proc. Biol. Soc. Wash. (IF 0.5) Pub Date : 2018-01-01 John W. Brown
Abstract The results of over 100 years of inventory work on the Lepidoptera of Plummers Island, Montgomery County, Maryland, U.S.A., were summarized recently in a volume dedicated to the invertebrate fauna of that site. That work documented a cumulative total of 836 species of Lepidoptera. To that list I add 20 species: Niditinea sabroskyi Metz, Davis & Davis, 2018 (Tineidae), Tinea carnariella Clemens

Taxonomic evaluation of the three “type” specimens of the fringe-footed shrew, Sorex fimbripes (Mammalia: Soricidae) and recommended nomenclatural status of the name Proc. Biol. Soc. Wash. (IF 0.5) Pub Date : 2018-01-01 Neal Woodman
Abstract.— John Bachman (1837:391) described the “fringe-footed shrew,” Sorex fimbripes Bachman, 1837, in his landmark monograph on the North American Soricidae (Mammalia: Eulipotyphla), in which he recognized 13 uniquely New World species. Characters he attributed to S. fimbripes resulted in its being interpreted as a tiny, semi-aquatic species and contributed to the complexity of its subsequent taxonomic

A new species of Choerophryne (Anura: Microhylidae) from Papua New Guinea Proc. Biol. Soc. Wash. (IF 0.5) Pub Date : 2018-01-01 Fred Kraus
Abstract I describe a new species of small microhylid frog from the southern versant of New Guinea that is characterized by its long and narrow proboscis, relatively large size and long legs, narrow discs on all fingers, hidden tympanum, and details of color pattern. This represents the twelfth species of long-snouted Choerophryne known and the third from the southern versant of the island's Central

Rediscovery of the type series of the Acadian Masked Shrew, Sorex acadicus (Mammalia: Soricidae), with the designation of a neotype and a reevaluation of its taxonomic status Proc. Biol. Soc. Wash. (IF 0.5) Pub Date : 2018-01-01 Neal Woodman
Abstract The name Sorex acadicus Gilpin, 1865 is currently recognized as the valid name for the Nova Scotian subspecies of the masked shrew, S. cinereus Kerr, 1792 (Mammalia: Soricidae), but a holotype for the taxon was never designated, and the location of the type series has been a mystery. The authority for this species, John Bernard Gilpin, was associated with the Nova Scotia Museum, Halifax, NS

Presenting a new genus within Strombidae (Mollusca: Gastropoda: Littorinimorpha) with notes on the taxonomic position of Strombus (Lentigo) micklei and the validity of Strombus (s.l.) blanci Proc. Biol. Soc. Wash. (IF 0.5) Pub Date : 2018-01-01 Aart M. Dekkers, Stephen J. Maxwell
Abstract.— One of the problems with undertaking revisions within Strombidae Rafinesque, 1815 is the tendency for chaining within the genus Strombus Linné, 1758. Strombus is often used taxonomically as a holder for confusing taxa acting in sensu lato (s.l.). This paper addresses one of the chaining issues with Strombus with the erection of Striatostrombus gen. nov. This revision is based on morphology

Echiniscoides rugostellatus a new marine tardigrade from Washington, U.S.A. (Heterotardigrada: Echiniscoidea: Echiniscoididae: Echiniscoidinae) Proc. Biol. Soc. Wash. (IF 0.5) Pub Date : 2018-01-01 Emma S. Perry, Paul Rawson, Natalie J. Ameral, William R. Miller, Jeffrey D. Miller
Abstract The first new species of tardigrade in the family Echiniscoididae from the west coast of America is presented with an integrative description. Echiniscoides rugostellatus n. sp. was found on barnacles from a piling, in the Straits of Juan Fuca, Puget Sound, Port Townsend, Washington, USA. The new species is named after its granulated dorsal cuticle and the star-shaped tip of its internal and

Fishes collected by Captain John M. Dow mainly on the Pacific coast of Central America (1861–1865) and deposited in the National Museum of Natural History, Smithsonian Institution Proc. Biol. Soc. Wash. (IF 0.5) Pub Date : 2018-01-01 David G. Smith
Abstract The collection of fishes made by Captain John M. Dow of the Panama Railroad Company represents one of the earliest and most important collection of fishes from the Pacific coast of Central America. There are 133 entries in the Division of Fishes catalog attributed to Dow, of which 81 can currently be located. These represent some 61 species and include 29 types. The material is summarized

Description of two deep-water fishes of the genus Diplotaxodon (Teleostei: Cichlidae) from Lake Malaŵi, Africa Proc. Biol. Soc. Wash. (IF 0.5) Pub Date : 2018-01-01 Jay R. Stauffer, Titus B. Phiri, Adrianus F. Konings
Abstract Two species of haplochromine cichlid fishes of the genus Diplotaxodon Trewavas, endemic to Lake Malaŵi are described: Diplotaxodon longimaxilla, new species, and Diplotaxodon altus, new species. Diplotaxodon altus is diagnosed from other species in the genus based on body depth (35.1–37.8% SL), number of gill rakers (21–26), and a smaller cheek depth (18.2–20.0% HL). Diplotaxodon longimaxilla

Population genetic structure of the intertidal kinorhynch Echinoderes marthae (Kinorhyncha; Cyclorhagida; Echinoderidae) across the São Sebastião Channel, Brazil Proc. Biol. Soc. Wash. (IF 0.5) Pub Date : 2018-01-01 Phillip V. Randsø, Maikon D. Domenico, Maria Herranz, Eline D. Lorenzen, Martin V. Sørensen
Abstract Barriers to gene flow in marine environments vary between species and are highly dependent on dispersal ability and habitat discontinuity. Intertidal sand and mud flats are discontinuous areas, separated by other habitat types along a coastline or by subtidal zones. The São Sebastião Channel in eastern Brazil, which is situated between Rio de Janeiro and São Paulo, harbors two intertidal mud

Nomenclatural notes on the genus Favia (Anthozoa: Scleractinia: Faviina: Faviidae) Proc. Biol. Soc. Wash. (IF 0.5) Pub Date : 2018-01-01 Rosemarie C. Baron-Szabo
Abstract The genus Favia Oken, 1815, represents one of the most widely used taxa in scleractinian history but is formally unavailable because vol. 3 (Zoologie) of Oken's (1815) work Lehrbuch der Naturgeschichte, in which the name was first published, was rejected by the ICZN for nomenclatural purposes (Opinion 417, September 1956). De Blainville (1820, p. 293–294) was the first author who used the
