  • 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.

  • Mystaxiops: A new genus of small minnow mayflies (Ephemeroptera: Baetidae) from Papua New Guinea
    , 2020
    Co-Authors: W P Mccafferty

    Abstract:

    Newly discovered larvae of the mayfly family Baetidae in Papua New Guinea are described as Mystaxiops venatoris, new genus and new species. The new genus is shown to belong to a monophyletic, predatory subgroup of the Centroptiloides complex, which was previously known only from the Afrotropics. The labrum of the new genus is extremely produced into a friction pad, and other mouthpart characteristics also demonstrate adaptations for predation. Labial palps and hypopharynx are distinct from all other related genera. Functional morphology of mouthparts and historical biogeography are hypothesized.

  • 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.

  • 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.

  • 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
