  • Natterer in Neotropical Nematoda: Species Described by Rudolphi, Diesing,
           and Molin

    • Authors: Ricardo Guerrero
      Abstract: Between 1817 and 1835 Johann Natterer collected 1,729 samples of endoparasitic helminths in Brazil and southern Venezuela. Of the 323 names that were assigned to the collected nematode specimens, 163 are still valid and accepted species, 84 are still doubtful, and 76 must be rejected. In this work, each name is analyzed and correlated to the literature to clarify its taxonomic status.The purpose of this review of the material collected by Natterer is to establish a complete list of all described species; their current status; and whether they are valid species, synonyms, or nomen nudum as well as to update the hosts and the original dates and localities where they were collected.

  • Diversity of Tetrabothriidae (Eucestoda) among Holarctic Alcidae
           (Charadriiformes): Resolution of the Tetrabothrius jagerskioeldi Cryptic
           Species Complex— Cestodes of Alcinae—Provides Insights on the
           Dynamic Nature of Tapeworm and Marine Bird Faunas under the Stockholm
           Paradigm

    • Authors: Eric P. Hoberg et al.
      Abstract: We begin resolution of the Tetrabothrius jagerskioeldi–species complex with descriptions of Tetrabothrius alcae n. sp. based on numerous specimens, primarily in murres (species of Uria), from the greater North Pacific basin and Tetrabothrius sinistralis n. sp. based on cestodes in guillemots (species of Cepphus) from the central Bering Sea and West Greenland. These tetrabothriids are characterized, among 44 species of Tetrabothrius in avian hosts, by attributes of the scolex, male and female organ systems, structure and dimensions of the vitelline gland, numbers of testes, configuration of the genital atrium, genital papillae and the male and female atrial canals, position of the genital ducts relative to the poral osmoregulatory canals, structure, dimensions and position of the vaginal seminal receptacle, and dimensions of the embryophore and oncosphere, in addition to a broader array of characters. Remarkably, T. alcae, T. sinistralis, and a cryptic complex had remained unrecognized for the past century, given that these species are unequivocally differentiated by multiple suites of unique structural attributes relative to T. jagerskioeldi. Alcids and cestodes of the T. jagerskioeldi–complex are restricted to cold marine systems of advection and upwelling along coastal margins adjacent to the continental shelf or are associated with archipelagos (especially the Aleutian Arc), isolated islands and rocky headlands of the Bering Sea, Chukchi Sea, Gulf of Alaska, Sea of Okhotsk, and Sea of Japan. Tetrabothrius alcae, T. jagerskioeldi, and T. sinistralis may occur in sympatry but with minimal overlap in the faunas associated with murres (Alcini) and guillemots (Cepphini). Transmission for cestodes and persistence of this fauna is expected to be associated with pelagic and neritic systems adjacent to colony sites in zones where critical prey species are concentrated or secondarily dispersed downstream by predictable advective and upwelling processes and become available to foraging birds. Faunal assembly represents the outcomes of oscillating climate, shifting ranges (breakdown in isolation, ecological fitting, and exploration modes for cestodes) and the changing interfaces for resource availability maintained by trophic and habitat overlaps. Dynamics at these ecotones constitute the nexus of opportunity and capacity for infection by species of Tetrabothrius among avian hosts where capacity appears broad and opportunity is ecologically restricted in space and prevatime. Life history pathways for cestodes are tied to trophic associations and dynamics at mesoscales across marine domains and provinces. Resilience and connectivity through ecological fitting strongly suggest the influence of multiple trophic pathways for transmission and persistence of this complex fauna through differing assemblages of zooplankters, fishes, and cephalopods depending on locality, oceanographic conditions, and temporal variability. Changing conditions, especially ecological perturbations driven by climate oscillations, directly determine production cycles and distributions of micro- and macro-zooplankton, forage fishes, cephalopods, and trophic structure in high-latitude marine ecosystems. Expanding regimes of accelerating change emphasize the critical importance of field collections, archives, and baselines to assess biological outcomes across temporal and spatial scales. Parasite assemblages reveal macro- to meso-scale connectivity serving as adjuncts and proxies in recognizing and understanding outcomes for episodes of environmental oscillation and directional atmospheric and oceanic warming in marine ecosystems.

  • A Guide to Helminth Parasites Reported from Shorebirds (Charadriidae) from
           the Americas

    • Authors: Albert G. Canaris et al.
      Abstract: The shorebird family Charadriidae in the Americas consists of 21 native and 7 vagrant species. Members of the family occupy a diversity of open habitats, ranging from Arctic tundra during nesting, coastal sands, and mudflats to inland prairies, savannas, and wetlands. Some native plovers migrate from nesting grounds in North America to wintering grounds in South America (Hayman et al., 1986; Paulson, 2005; Winkler et al., 2020). Our search of the literature revealed the following: 17 of 28 host species infected with helminth parasites, 153 helminth species, and 199 infections involving 13 geographic areas. The purpose of this guide is to provide easy access to this data and information relevant to helminth infections in charadriids from the Americas. Information is summarized in Tables I–VI. Table I lists in sequence host, parasite, geographic location, and attenuated citation. Common names are given for each host. Host names are listed alphabetically, and older scientific names used in the literature search are in parentheses. Host geographic distribution is abbreviated as follows: NA = North America, M = Mexico, CA = Central America, SA = South America, A = Americas (NA + M + CA + SA). If present, parasite species are listed in the following order: trematode, cestode, nematode, and acanthocephala. The helminth species names are listed as they were given in the cited literature. Tables II–V are parasite-host lists for trematode, cestode, nematode, and acanthocephalan species and host of the species associated with the parasite. Table VI is a summary of information extracted from the tables and literature cited section.

  • Steganoderma Stafford, 1904 (Digenea: Zoogonidae: Lepidophyllinae) from
           Two Species of Rockfishes from Deep Waters off Oregon Including a New
           Species and an Updated Key to Species of This Genus

    • Authors: Charles K. Blend et al.
      Abstract: Steganoderma eamiqtrema n. sp. and a single unidentified specimen of Steganoderma Stafford, 1904 (Zoogonidae: Lepidophyllinae) obtained from the intestine of the greenstriped rockfish, Sebastes elongatus Ayres, 1859, and the flag rockfish, Sebastes rubrivinctus (Jordan and Gilbert, 1880) (Scorpaeniformes: Sebastidae), collected from 190–200 m depths off Oregon, USA, are described. The new species is distinguished from its seven other congeners by a diagnostic combination of morphological features including an elongate oval to spindle-shaped body, a clavate to comma-shaped cirrus pouch located in the forebody and hindbody, a bipartite seminal vesicle, a bifurcal or just post-bifurcal genital pore, a larger ventral than oral sucker, and a smooth testes and ovary with a relatively small distance between them. We present an updated key to the eight species now in Steganoderma and provide a list of parasites known from Se. elongatus and Se. rubrivinctus. The discovery of S. eamiqtrema in Se. elongatus represents the second species of zoogonid known from this host, and the finding of Steganoderma sp. in Se. rubrivinctus represents the first report of a digenean from this host species. A detailed discussion also is given of the type species, S. formosum Stafford, 1904, and questions are raised as to whether this species has a worldwide distribution and infects such a wide variety of fish hosts. We present evidence including variation we observed in redescriptions of the type species, query the implausible idea that there could be gene flow between conspecific helminths geographically separated in the North Atlantic and North Pacific Oceans over such a vast geological period, and offer the possibility that some prior reports of S. formosum may, indeed, be S. eamiqtrema; all of which suggests S. formosum sensu lato may be part of a species complex and not the same worldwide species. Steganoderma is represented in the deep sea by S. eamiqtrema, S. formosum, and Steganoderma sp., and limited speculation is given as to the host specificity of this genus and life history strategies of the new species in deeper waters. Finally, molecular studies of species of Steganoderma are sorely needed (i.e., there is no DNA sequence data currently available in GenBank for any species of this genus), and we suspect that with further molecular, morphological, and life history work, this genus will be taxonomically divided up.

  • Two New Nematodes from the Families Molineidae and Strongyloididae
           (Nemata): Parasites of Caenolestes (Mammalia: Paucituberculata:
           Caenolestidae) from the Andes of Ecuador

    • Authors: Ricardo Guerrero
      Abstract: A new genus and species of Molineinae (Nemata: Trichostrongyloidea) is described. It is similar to Molineus but differs in ray 4 being longest instead of shortest. In addition, a new species of Parastrongyloides is described that is characterized by a short digitiform appendix on the tail and spicule tips with fine points. It is the second species known with two morphotypes of the females. Resumen:Se describe un nuevo género y especie de Molineinae (Nemata: Trichostrongyloidea), similar a Molineus pero difiere en que en la bolsa caudal el rayo 4 es el más largo en lugar de sewr el más corto. Además, se describe una nueva especie de Parastrongyloides que se caracteriza por un apéndice digital corto y las espículas terminan con puntas finas. Es la segunda especie conocida con dos morfotipos de hembras.

  • The Enigmatic Spelaeorhynchidae Oudemans, 1902 (Acari: Mesostigmata)
           Blood-Feeding Ectoparasites Infesting Neotropical Bats, with Catalog and
           Notes on a Collection from the Manú Biosphere Reserve in Peru

    • Authors: Donald Gettinger et al.
      Abstract: A survey of ectoparasites associated with bats collected along an elevational transect in the Manú Biosphere Reserve, Peru, includes specimens of two species of an unusual and rarely collected family of parasitic mites, the Spelaeorhynchidae Oudemans, and reveals information on the natural occurrence of these infections. In lowland rainforest (450–1,000 m) along the Rio Alto Madre de Dios, Spelaeorhynchus soaresi Peracchi was recorded exclusively infecting two species of frugivorous Carollia, C. brevicauda and C. perspicillata. At higher elevations in the mountains and cloud forests, Spelaeorhynchus praecursor Neumann exclusively infected two species of nectarivorous Anoura, A. cultrata and A. geoffroyi. The consistency of both altitudinal and host distributional limits between sampling periods suggests that the true focus of infection may be sustained in certain habituated, long-term roosting sites. This valuable spelaeorhynchid survey collection (slides and vials) is available for further study at the following repositories: the Harold W. Manter Laboratory of Parasitology, University of Nebraska–Lincoln, and the Field Museum of Natural History, Chicago.

  • Insights about Diversity of Tetrabothriidae (Eucestoda) among Holarctic
           Alcidae (Charadriiformes): What Is Tetrabothrius jagerskioeldi'

    • Authors: Eric P. Hoberg et al.
      Abstract: Tetrabothriid cestodes are characteristic helminths that infect species of seabirds globally. We begin with the exploration of the diversity of tapeworms of the genus Tetrabothrius Rudolphi, 1819 (Eucestoda: Tetrabothriidae), some of which are distributed among seabirds of the family Alcidae (Charadriiformes) at boreal to higher latitudes of Holarctic seas. During the course of 2 decades of field inventory from 1975 through the early 1990s (in addition to earlier collections assembled by Robert L. Rausch and colleagues in Alaska initiated in the late 1940s), an extensive series of tapeworm specimens attributable to species of Tetrabothrius was recovered from seabirds across the North Pacific Basin. It was assumed based on published records of species richness in this fauna that a single species, Tetrabothrius jagerskioeldi Nybelin, 1916, would predominate among alcid hosts. In contrast, detailed study revealed considerable morphological complexity that could not be accommodated within a single species. Further, it was apparent that the limits for the primary morphological attributes of T. jagerskioeldi were not clearly defined. We redescribe T. jagerskioeldi based on direct examination of the type series of specimens from Sweden and an assemblage of specimens largely from alcid hosts from the North Pacific basin. Specimens of T. jagerskioeldi are diagnosed by a characteristic configuration of the genital atrium, position of the male and female genital canals, structure of the male and female organ systems, and numbers of testes. Based on the spectrum of characters we explored, it was apparent that numerous specimens of Tetrabothrius among genera and species of Alcidae from the North Pacific inventory could not be accommodated in T. jagerskioeldi and provisionally are referred to Tetrabothrius undescribed n. sp. pending ongoing evaluations. Superficially, these are all large and robust tapeworms referable to Tetrabothrius, potentially contributing to misidentifications and misattribution that have occurred both in the literature and in the few archived specimens in museums. We summarize the results of extensive inventory collections since 1950, establishing a distributional baseline for species of Tetrabothrius from a wide range of geographic localities and an assemblage of host species among the Alcidae and some species of Laridae, Stercorariidae, and Phalacrocoracidae. We further evaluate the validity of historical published records for T. jagerskioeldi and other congeners among alcids and other seabirds. A conclusion that emerges is that T. jagerskioeldi is a rare tapeworm with a patchy distribution in pelagic to nearshore marine environments, showing considerable heterogeneity in space and time, among alcid seabirds across high-latitude seas of the Holarctic. Prior concepts for host range require reevaluation. We demonstrate that the associations for T. jagerskioeldi are relatively narrow and appear to involve a more limited spectrum of alcid hosts, and less often other species of marine birds, than currently assumed. A robust understanding of parasite species diversity and distribution is critical in establishing baselines across marine ecosystems. Our current study among species of Tetrabothrius, especially in the North Pacific basin and Bering Sea ecosystem contributes to development of a series of specimen-centered baselines derived primarily from the late 1970s to the early 1980s against which accelerating perturbations linked to climate warming and ocean-atmosphere interactions may be explored. Detailed knowledge of specimen-based faunal diversity for parasites provides a cumulative, temporal, and spatial snapshot and proxy for conditions in marine foodwebs and the continuity of trophic linkages.

  • Checklist of Bloodfeeding Mites (Acari: Spinturnicidae) from the Wings of
           Bats (Mammalia: Chiroptera) in the Manú Biosphere Reserve, Peru

    • Authors: Donald D. Gettinger
      Abstract: A survey collection of mites of the family Spinturnicidae from Peruvian bats includes 11 species of Periglischrus (acutisternus, gameroi, grandisoma, herrerai, hopkinsi, iheringi, micronycteridis, ojasti, paracutisternus, paravargasi, and ramirezi) and 2 Spinturnix (americanus and bakeri); almost all represent new locality records. This survey collection is available for further study at the following repositories: The Harold W. Manter Laboratory of Parasitology, University of Nebraska–Lincoln; the Field Museum of Natural History, Chicago; and the Laboratório de Espeleobiologia y Acarologia, Universidad Nacional Autónoma de México. When spinturnicid mites are collected to avoid cross-contamination by mites among species of bats, parasitic associations are consistently host specific, with Periglischrus spp. distributed exclusively on phyllostomid bats, and Spinturnix spp. on vespertilionids. Notable disjunctions within the Manú Reserve include an absence of spinturnicids on bats of the genus Carollia (Phyllostomidae), or with Chiroderma villosum (Stenodermatinae). Mites of the family Spinturnicidae are not normally associated with bats of the families Emballonuridae, Molossidae, or Noctilionidae.En una colección de ácaros de la familia Spinturnicidae en murciélagos peruanos se encontraron 11 especies de Periglischrus (acutisternus, gameroi, grandisoma, herrerai, hopkinsi, iheringi, micronycteridis, ojasti, paracutisternus, paravargasi, y ramirezi) y 2 Spinturnix (americanus y bakeri); la mayoría representan nuevos registros de localidad. Esta colección está disponible para su posterior estudio en las siguientes instituciones: Laboratorio de Parasitología Harold W. Manter, Universidad de Nebraska–Lincoln, Field Museum of Natural History, Chicago, y Laboratorio de Espeleobiología y Acarología, Universidad Nacional Autónoma de México. Si los espinturnicidos se recolectan evitando la contaminación cruzada de los ácaros, entre las especies de murciélagos, las asociaciones parasitarias son consistentemente específicas al hospedador, con Periglischrus spp. distribuido exclusivamente en murciélagos phyllostomidos y Spinturnix spp. en vespertilionidos. Las disyunciones notables dentro de la Reserva de Manu incluyen una ausencia de espinturnicidos en los murciélagos del género Carollia (Phyllostomidae), o con Chiroderma villosum (Stenodermatinae). Los ácaros de la familia Spinturnicidae normalmente no están asociados con murciélagos de las familias Emballonuridae, Molossidae, y Noctilionidae.

  • Acarine Biodiversity in Ecuador: Two New Species of Endoparasitic Chiggers
           (Acarina: Trombiculidae) from Terrestrial Andean Anurans

    • Authors: Ricardo Guerrero et al.
      Abstract: Two species of endoparasitic chiggers, Vercammenia neotropica n. sp. and Microtrombicula ecuadorensis n. sp., are described, both found in terrestrial anurans of the genus Pristimantis collected in the Andes of Ecuador. A new combination is proposed for Trombicula yorkei Sambon, 1928 as Microtrombicula yorkei (Sambon, 1928) n. comb., and Schoengastia lynni Ewing, 1942 is placed as incertae sedis. This is the first record of species of the genus Vercammenia in the Neotropical region.Dos especies de ácaros endoparásitos, Vercammenia neotropica n. sp. y Microtrombicula ecuadorensis n. sp., son descritas, ambas encontradas en anuros terrestres del género Pristimantis recolectados en los Andes de Ecuador.
