{"title":"Chaetonotus triacanthus and Heteroxenotrichula texana two new chaetonotid gastrotrichs from the Gulf of Mexico","authors":"M. Todaro","doi":"10.2307/3226575","DOIUrl":"https://doi.org/10.2307/3226575","url":null,"abstract":"The first paucitubulatine chaetonotid gastrotrichs are reported from the Gulf of Mexico. Chaetonotus triacanthus n. sp. and Heteroxenotrichula texana ri. sp. are described from sandy sediment collected along the northern part of Padre Island, Texas, U.S.A. C. triacanthus is characterized by short lamella-bearing spines on the dorsal side of head and neck, three long spines on the dorsal posterior end, and a pair of three-keeled scales on the furcal base. C. texana belongs to the \"subterranea\"-species group, and is characterized by pedunculated scales that cover the posterior half of the ventral surface. The gastrotrich fauna of the Gulf of Mexico is poorly known. To date, six genera, Acanthodasy, Dolichodasys, Macrodasys, Neodasys, Tetranchyroderma, and Turbanella and three species, Dolichodasys carolinensis, D. elongatus, and Turbanella ocellata have been reported from the region (Fox & Powell, 1986; Friauf, 1968; Meyers et al., 1987, 1988; Ruppert & Shaw, 1977). In the spring of 1992, with the aim of assessing the gastrotrich diversity of the Gulf of Mexico, an extensive qualitative survey along the coasts of Alabama, Mississippi, Louisiana, and Texas was initiated. Herein two new paucitubulatine chaetonotids, the first being reported from the region, are described and figured. A more comprehensive account on the species encountered to date is in preparation. MATERIALS AND METHODS On 16 August 1992, 500 g of intertidal sand were obtained by scooping sediment from the bottom and side of a 0.5-m-deep hole dug in the beach on North Padre Island, Texas, U.S.A. (Fig. 1). Similarly, sediment was obtained on 10 March 1993 from the public beach of Port Aransas, Texas. In both cases, the tide was incoming. Within 48 h, the samples were brought to the laboratory, kept in a coldroom at 14?C, and processed within one week. Gastrotrichs were extracted daily from the sediment by the narcotization-decantation technique of Higgins & Thiel (1988), using a 7% MgC12 solution. Living, relaxed specimens were observed, using differential-interference contrast, under a Microphot-FXA Nikon microscope. At that time, gastrotrichs were photographed and/or re' I thank Dr. J. W. Fleeger for his support throughout the study. Thanks also are due Dr. W. D. Hummon for providing me with important information on gastrotrichs from Grand Isle, Louisiana. Special thanks go to Mrs. Candace Conn for bringing in the first sample of sand from North Padre Island, Texas. Drs. M. Balsamo, W. A. Evans, W. D. Hummon, P. Tongiorgi, and two anonymous reviewers have improved the manuscript with invaluable comments. Mr. Ron Bouchard helped to assemble the figures.

{"title":"Physalopteroides bahamensis n. sp. (Nematoda: Spiruroidea) from the Cuban Treefrog Osteopilus septentrionalis (Hylidae) from San Salvador Island, Bahamas","authors":"C. Bursey, S. Goldberg","doi":"10.2307/3226645","DOIUrl":"https://doi.org/10.2307/3226645","url":null,"abstract":"Four hundred eighty-six specimens of Physalopteroides bahamensis n. sp. (Nematoda: Spiruroidea: Physalopteridae) were recovered from the gastrointestinal tracts of 61 of 72 preserved specimens of the Cuban treefrog, Osteopilus septentrionalis. Prevalence of infection was 85% and mean intensity was 8.4. Physalopteroides bahamensis belongs to the group of Physalopteroides species with a smooth left lip. The new species also is distinguished by number of teeth on the right lip, symmetrical caudal alae, unequal spicules, and arrangement of caudal papillae. These nematodes represent the third known species of Physalopteroides from the Western Hemisphere and the first report of the genus from the Bahamas. Wu & Liu (1940) erected the genus Physalopteroides to accept a new nematode species recovered from the Asian long-nosed tree snake, Ahaetulla (=Dryophis) prasinus (Reinwardt, 1827), from Kwangsi, China. The generic diagnosis included the possession of teeth on the right lip only. This description was modified by Chabaud & Brygoo (1960) to include all species with dentation limited to one lip, and six species were transferred from the genus Thubunaea. There are currently 15 described species of Physalopteroides, six from the Ethiopian Realm, six from the Oriental Realm, one from the Australian Realm, one from the Neotropical Realm, and one from the Nearctic Realm (see Baker, 1987; Elwasila, 1990). Physalopteroides bahamensis n. sp. is the second species described from the Nearctic Realm. The Cuban treefrog, Osteopilus septentrionalis Dumeril & Bibron, 1841 is known from Cuba, Island de Pinos, the Bahamas, and the Cayman Islands and has been introduced in Puerto Rico, St. Croix, South Florida, and the Florida Keys (Schwartz & Henderson, 1991). The species is widespread but occurs primarily in mesic habitats. On San Salvador Island, Bahamas, it is sympatric with the frog Eleutherodactylus planirostris Cope, 1863 and the lizards Anolis distichus Cope, 1862, A. sagrei Drumeril & Bibron, 1837, Cyclura rileyi Stejneger, 1903, Leiocephalus loxogrammus Cope, 1887, and Sphaerodactylus corticola Garman, 1888. 0. septentrionalis was reported to harbor at least 11 species of nematodes (see Coy Otero & Ventosa, 1984).

Cavernicolous pseudoscorpions are reported from Ohio for the first time; these are Chthonius (Ephippiochthonius) virginicus, Hesperochernes mirabilis, and an unusual new, blind species described as Apochthonius hobbsi n. sp. Additions to the sparse cave fauna of Indiana are Hesperochernes mirabilis and Hesperochernes holsingeri n. sp. and an undescribed chthoniid represented only by an isolated palp. The pseudoscorpion fauna of Ohio and Indiana is poorly known. Only seven species have been reported from Ohio, none from caves (Hoff, 1958). Thirteen species are known from Indiana, including two from caves (Hoff, 1958; Muchmore, 1963, 1967, 1976); the cavernicolous species are Apochthonius indianensis Muchmore from Donaldson's Cave and Donnehue's (Donahue's) Cave, both in Lawrence Co., and Kleptochthonius (Chamberlinochthonius) packardi (Hagen) from Wyandotte Cave, Crawford Co. (Harvey, 1991; Muchmore, 1963). A stimulus to improve our knowledge of pseudoscorpions in Ohio was provided by Horton H. Hobbs III, who, with his students at Wittenberg University, explored and surveyed many caves in Ohio and collected numerous zoological specimens. Included in these collections were a number of pseudoscorpions, which Dr. Hobbs kindly sent to me for examination. One of these represents a new species and is described below. The others belong to known species, but their occurrence in Ohio caves is noteworthy. A preliminary list of these collections was provided by Hobbs & Flynn (1981). The opportunity also is taken to report on small, but interesting, collections of pseudoscorpions made by J. R. Holsinger in Wilson's Cave, Jefferson Co., Indiana and by J. J. Lewis in Potato Run Cave, Harrison Co., Indiana. From these, a new species is described, a new record is established, and a fragmentary specimen is described and discussed.","PeriodicalId":23957,"journal":{"name":"Transactions of the American Microscopical Society","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1994-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88457563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
