  • Revisions To Plauditus Cestus And P-Gloveri (Ephemeroptera : Baetidae)
    Entomological News, 2020
    Co-Authors: W P Mccafferty, Luke M Jacobus
    Abstract:

    Two species of the North American genus Plauditus (Ephemeroptera: Baetidae), P. cestus and P. gloveri, are shown to be apotypic sister species. All type specimens associated with both species were re-examined. Certain published larval character descriptions and figures are corrected; for example, mouthpart morphology is shown to be essentially similar in both species. Intraspecific variability is discussed based on previously reported variants and new variants of P. cestus, especially from New York and Wisconsin. Consistently reliable characteristics for diagnosing larvae of the two species are given, including both structural and color pattern differences. Species distributional ranges are updated.

  • The Bugilliesia Complex of African Baetidae (Ephemeroptera)
    2020
    Co-Authors: C. R. Lugo-ortiz, W P Mccafferty
    Abstract:

    The Bugilliesia complex is a distinct grouping of Afrotropical Baetidae (Ephemeroptera) genera distinguished by a conspicuous basomedial protu berance on segment 2 of the male genital forceps. It includes Potamocloeon Gillies; Afrobaetodes Demoulin; Kivua McCafferty & Lugo-Ortiz, new genus; Rhithrocloeon Gillies; Bugilliesia Lugo-Ortiz & McCafferty, new genus; and Mutelocloeon Gillies & Elouard. Genera are each highly distinctive as larvae (Kivua remains unknown as larvae), but the complex is not definable in the larval stage. Cladistic analysis shows Potamocloeon to be the most plesiotypic lineage, with all other genera sharing larval apomorphies. Kivua, Rhithrocloeon, Bugilliesia, and Mutelocloeon form the next sequential clade, and the latter three form the next. Bugilliesia and Mutelocloeon are the most apotypic, sister lin eages. Relationships are reflected in transitional changes in the unusual male genitalia. The recognition of the six sequenced species groups as genera constitutes a phylogenetic classification. Kivua consists of K. elouardi (Gillies), new combination, and K. insueta (Kopelke), new combination, thereby restrict ing Rhithrocloeon to consist of R. indicator Gillies and R. permirum (Kopelke). Bugilliesia consists of certain species previously considered in Afroptilum Gillies: B. gr?sea (Gillies), new combination; B. guineensis (Gillies), new combi nation; B. n?tida (Ulmer), new combination; B. notabilis (Kimmins), new combi nation; and B. sudanensis (Ulmer), new combination. Potamocloeon macafertiorum Lugo-Ortiz, new species, is described from northeastern South Africa, and represents a considerable range extension for the genus. Afrobaetodes intermedius Lugo-Ortiz & McCafferty, new species, is described from northeastern South Africa. Diagnosis of all genera are given along with species inclusions and distributions.

  • New Baetidae (Insecta: Ephemeroptera) from Lake Malawi
    2020
    Co-Authors: W P Mccafferty
    Abstract:

    Deux especes nouvelles d'ephemeres Pisciforma (Insecta : Ephemeroptera : Baetidae) ont ete decouvertes dans le Lac Malawi, Afrique. Cheleocloeon littorale McCafferty, n. sp., est la septieme espece du genre connue de la region Afrotropicale. Les larves, sur lesquelles est basee la description de l'espece, se distinguent de toutes les autres par des caracteres tels que le court palpe maxillaire, la rangee unique et bien developpee de denticules tarsaux, et les epines marginales de la paraprocte bien developpees. Il s'agit de la troisieme espece de Cheleocloeon avec des ailes posterieures presentes chez le mâle mais absentes chez la femelle, et c'est la premiere a etre signalee d'habitats lacustres. Maliqua abdallahi McCafferty, n. sp. est decrite aussi a partir de larves et represente la seconde espece connue de ce genre et la premiere capturee en habitats lacustres. Elle se distingue principalement par ses griffes depourvues de denticules, l'armature des pattes et la faible tracheation branchiale. Les caracteres generiques sont discutes ainsi que l'habitat et les groupements d'especes d'ephemeres du Lac Malawi.

  • Gose's African Ephemeroptera (Baetidae, Heptageniidae)
    Entomological News, 2020
    Co-Authors: W P Mccafferty
    Abstract:

    Three new species of small minnow mayflies (Ephemeroptera: Baetidae) are described from larvae taken in the Democratic Republic of Congo as follows: Acanthiops gosei, n. sp., Dicentroptilum imanishii, n. sp., and Tanzaniella gorillora, n. sp. Each of these species is structurally distinctive within the Afrotropical genus to which it belongs. With respect to D. imanishii, the concept of Dicentroptilum is slightly expanded to accommodate the new species, and an analysis of the relationships with Xyrodromeus is given. With respect to T. gorillora, a more comprehensive analysis of the relationships of Tanzaniella with Demoreptus and certain other Baetis complex genera is given. The significance and interpretation ofsuch characters as dorsal abdominal tubercles, numbers of rows of claw denticles, and integrity of mandibular incisors in Baetidae are discussed. Larvae oftwo species of Heptageniidae from D. R. Congo are placed to Afronurus, but must remain unnamed as species.

  • Lugoiops maya, a new genus and species of ephemeroptera (Baetidae) from Central America
    2020
    Co-Authors: W P Mccafferty, D. E. Baumgardner
    Abstract:

    Small minnow mayfly (Ephemeroptera: Baetidae) larvae taken from a mountain rivulet in Baja Verapaz, Guatemala are described as Lugoiops maya, new genus and new species. The new genus is a member of the Baetodes complex ofgenera, being more advanced than Moribaetis or Mayobaetis, and sharing numerous synapomorphies with both Prebaetodes and Baetodes, and additional synapomorphies with Baetodes. The precise cladistic relationships deduced for the new genus are discussed and a new key to genera of the Baetodes complex is provided. Larvae of L. maya are striking because of their relatively large size, unique structural characteristics, such as absence of gills 1, and their torrential habitat.

  • Tapajobaetis, a remarkable new genus of Baetidae with spatulate claws (Ephemeroptera)
    Annales De Limnologie-international Journal of Limnology, 2017
    Co-Authors: Rafael Boldrini, Frederico Falcao Salles
    Abstract:

    The Baetidae family is represented by 32 genera from the Neotropics. A new genus, Tapajobaetis , and a new species, T. labiosus , are described based on nymphs and adults from the Brazilian Amazon region. The nymph, with highly modified head and mouth parts is readily distinguished from other genera of this family by the following combination of characters: presence of fine, simple setae on scape and pedicel, labial and maxillary palpi elongated, hind wing pads vestigial, and claws spatulate, with about 140 denticles. Adults, on the other hand, are more similar to other Baetidae and are characterized by the absence of hind wings, anteronotal protuberance slightly truncate and genitalia with posterior margin of subgenital plate convex, forceps segment III elongate. The nymphs were found exclusively over leaves of Thurnia sphaerocephala (Thurniaceae), in areas with moderate currents, and possess modification in the labial palp, which seems to be adapted to collect fine material.

  • callibaetis eaton ephemeroptera Baetidae from brazil
    Journal of Natural History, 2014
    Co-Authors: Paulo Vilela Cruz, Frederico Falcao Salles, Neusa Hamada
    Abstract:

    Callibaetis Eaton remains poorly known in South America. Some of the species in the genus are difficult to identify with confidence and most are known only at the adult stage. In this paper we increase the number of species known to occur in Brazil from 11 to 18; diagnoses of species are improved; five new species are described based on nymphs and reared adults of both genders (C. calloventer sp. nov., C. cruentus sp. nov., C. gelidus sp. nov., C. itannae sp. nov., C. nigracyclus sp. nov.); first records of two species are reported from Brazil (C. gonzalezi and C. sellacki); descriptions of unknown stages are made (C. gonzalezi male imago and C. jocosus nymph); redescriptions of known stage are provided for male and female imago of C. jocosus. Based on these data, keys for nymph, male and female imago are proposed for Brazil. http://zoobank.org/urn:lsid:zoobank.org:pub:019D55A5-8979-4D9A-BB16-CB1451C8DF1B

  • Paracloeodes caldensis (Ephemeroptera: Baetidae), an atypical new species from the Colombian Andes.
    Zootaxa, 2013
    Co-Authors: Yeisson Gutiérrez, Lucimar G. Dias, Frederico Falcao Salles
    Abstract:

    In the present work, an atypical new species of Paracloeodes Day (Ephemeroptera: Baetidae) is described based on nymphs collected in the Caldas Department, Central Cordillera of Colombia. This represents the first report of the genus from Colombia. The main characteristics that distinguish the new species from congeners are: abundant setae on femora, antennae length twice the width of the head capsule, maxilla with palp twice the length of the galea-lacinia, segment II of the labial palp with a rounded projection and 2.5 times the width of segment III, tarsal claws half the length of their respective tarsi and the abdominal color pattern. The concepts of the genera Paracloeodes , Varipes and Rivudiva are discussed in light of the discovery of P. caldensis n. sp.

  • The adults of Camelobaetidius janae Dominique & Thomas, 2001 and C. yacutinga Nieto, 2003, with a new synonym for C. leentvaari Demoulin, 1966 (Ephemeroptera: Baetidae)
    Zootaxa, 2013
    Co-Authors: Rafael Boldrini, Luke M Jacobus, Frederico Falcao Salles
    Abstract:

    The genus Camelobaetidius Demoulin, 1966 has 39 species distributed throughout the Nearctic and Neotropical Regions, being one of the most studied genera of the family Baetidae. Based on material from Brazil, the aim of the present paper is to describe adults of C. janae Dominique & Thomas, 2001 and C. yacutinga Nieto, 2003, and to recognize a new synonym for Camelobaetidius leentvaari Demoulin, 1966 (= C. mantis Traver & Edmunds, 1968 nov. syn.) based on the examination of type material.

  • a new genus and species of Baetidae insecta ephemeroptera from brazil
    Annales De Limnologie-international Journal of Limnology, 2013
    Co-Authors: Paulo Vilela Cruz, Frederico Falcao Salles, Neusa Hamada
    Abstract:

    A new genus (Callibaetoides ) and species (Callibaetoides caaigua ) of Baetidae (Ephemeroptera) is described based on nymphs and adults of both genders collected in forested areas of Amazonia and Mata Atlântica biomes. The nymphs were collected from leaf packs accumulated in the backwaters of small streams. The genus and species can be easily distinguished from other members of the family in South America by the following combination of characteristics: male and female imagos with costal process of hind wing centrally located and strongly projected; marginal intercalary veins long and paired in male imago; nymphs with deep medial emargination of labrum, maxillary palp three segmented and third segment of labial palp quadrangular.

  • Guloptiloides: an extraordinary new carnivorous genus of Baetidae (Ephemeroptera).
    Aquatic Insects, 2020
    Co-Authors: Jean-luc Gattolliat, Michel Sartori
    Abstract:

    Guloptiloides (Ephemeroptera, Baetidae), gen.n., is described to accomodate the species G. gargantua (larvae) and G. spA (female imagoes) based on specimens from the Eastern coast of Madagascar. Larvae of Guloptiloides are remarkable by the adaptation of the mouthparts to a predatory diet. It is also distinct from other genera in that adults have hindwings with 3 well-marked longitudinal veins and a single extremely developed spur on the costal margin. Affinities and ecology are discussed.

  • New larvae of Baetidae (Insecta: Ephemeroptera) from Espiritu Santo, Vanuatu
    2020
    Co-Authors: Jean-luc Gattolliat, Arnold H. Staniczek
    Abstract:

    During the Global Biodiversity Survey “Santo 2006” conducted in Espiritu Santo, Vanuatu, mayfl y larvae were collected in several streams of the island. This contribution deals with the larvae of Baetidae (Insecta: Ephemeroptera) that are represented by two species: Labiobaetis paradisus n. sp. and Cloeon sp. The presence of these two genera is not surprising as they both possess almost a worldwide distribution and constitute a great part of Australasian Baetidae diversity. Diagnoses of these two species are provided and their affi nities are discussed. K e y w o r d s : Australasia, Cloeon erromangense, Labiobaetis paradisus, mayfl ies, new species, Santo 2006, taxonomy. Zusammenfassung Im Rahmen der auf Espiritu Santo, Vanuatu, durchgefuhrten Biodiversitatserfassung “Santo 2006” wurden Eintagsfl iegenlarven in verschiedenen Fliesgewassern der Insel gesammelt. Der vorliegende Beitrag behandelt die Larven der Baetidae (Insecta: Ephemeroptera), die mit zwei Arten vertreten sind: Labiobaetis paradisus n. sp. and Cloeon sp. Der Nachweis beider Gattungen ist nicht uberraschend, da diese eine nahezu weltweite Verbreitung besitzen und einen grosen Anteil der Diversitat australasiatischer Baetidae ausmachen. Die beiden Arten werden beschrieben, beziehungsweise eine Diagnose gegeben, und Unterschiede zu anderen Formen werden diskutiert. Contents

  • Two New Genera of Baetidae (Ephemeroptera; Insecta) from Madagascar
    Aquatic Insects, 2020
    Co-Authors: Jean-luc Gattolliat
    Abstract:

    Two new genera of Baetidae (Ephemeroptera), Scutoptilum gen. n. and Echinopus gen. n., are described to accommodate three new species from Madagascar: Scutoptilum verrucosum sp. n., Echinopus giboni sp. n., Echinopus minutus sp. n.. They all share a unique apomorphy; they possess a subapico-transverse arc of long setae on the outer margin of femora. Scutoptilum presents important adaptations to fast flowing waters and mouthparts modified for scraping. Moreover, Scutoptilum shows an unusual general habitus with a prothorax broadly expanded laterally, forewing pads extremely developed and shape of the head subrectangular. Echinopus appears less derived and possesses more plesiomorphic features. Both genera are closely related to the Afrotropical genus Afroptilum and belong to the Centroptiloides complex.

  • A new genus of Baetidae (Insecta, Ephemeroptera) from Southeast Asia
    European journal of taxonomy, 2020
    Co-Authors: Thomas Kaltenbach, Jhoana M. Garces, Jean-luc Gattolliat
    Abstract:

    A new genus of Baetidae is described from Southeast Asia, Procerobaetis gen. nov. It has a wide distribution reaching from Indonesia (Sumatra) to the Philippines. Two new species are described from Indonesia, P. leptobranchius gen. et sp. nov. and P. petersorum gen. et sp. nov., and one new species from the Philippines, P. freitagi gen. et sp. nov. Procerobaetis gen. nov. is characterized by having seven pairs of elongate, apically pointed gills. At least gills I and II are very slender with strongly extended points, which is unique in Baetidae. Similar gills were described from Leptophlebiidae. Procerobaetis gen. nov. is further characterized by having long, slender legs with extended, slender and slightly bent claws. The antennae posess remarkable spines at the outer, lateral margin, which are maximally developed on segments IX–XI of the flagellum. No spines are present on the posterior margins of abdominal tergites I–VI. COI sequences were obtained from all three of the new species. The genetic distances (Kimura 2-parameter) between these species are between 13% and 20%. Very limited genetic distances of 0% to 1% were found between specimens of the same species. The occurrence of two different species in the same area of Sumatra is discussed.

  • cladistic analysis of the family Baetidae insecta ephemeroptera in south america
    Systematic Entomology, 2010
    Co-Authors: Carolina Nieto
    Abstract:

    The family Baetidae, which belongs to the order Ephemeroptera, was first described by Leach in 1815. Since then, almost 100 genera and 900 species have been described. Although diverse, this family is relatively homogeneous. The adults are extremely similar to one another, the wings vary little and the penes are membranous, features that significantly reduce differentiation among taxa. In contrast, the larvae have more conspicuous differences. Most are collector–gatherers, but a few are carnivorous or filter feeders. In South America, although knowledge concerning the 27 genera and 132 species of Baetidae described for this region has improved in the last three decades, phylogenetic relationships remain unknown. The present study, the first cladistic analysis of Baetidae in South America, included 70 species (55 are Neotropical) and 126 morphological characters. The matrix was analysed using tnt, under implied weights. Although the monophyly of the family Baetidae was obtained with good support, the subfamilies proposed originally (Baetinae, Cloeoninae and Callibaetinae) were recovered as paraphyletic. The Baetodes complex, as well as the relationships between genera, is discussed. The validity of some structures or characters as support of different groupings is also discussed.
