ABSTRACT
ABSTRACT A new species of Gripopteryginae stonefly, Tupiperla claudius sp. nov. (holotype male deposited in DZUP: Brazil, Paraná State, Piraquara municipality, Pico do Marumbi State Park), is described and diagnosed based on seven adult males. The new species differs from its congeners by the long T10 extension, dorsally with straight lateral margins and tip truncated, protruding into a pair of short downward teeth in lateral view; paraproct long, surpassing the T10 extension dorsally, with a basal membranous-like area and a row of minute spines on the middle of the appendage length dorsally. Specimens of T. claudius sp. nov. from the Protected Area Mananciais da Serra in the Serra do Mar represent the very first gripopterygids recorded in the state of Paraná and are also a remarkable record for the genus for the southern Brazilian Atlantic Forest.
ABSTRACT
ABSTRACT Three Atlantic Forest endemic species of emerald dragonflies of the genus Navicordulia Machado & Costa, 1995 are reviewed through a morphological comparative analysis. All name-bearing types and additional specimens of the Navicordulia atlantica-complex—Navicordulia atlantica Machado & Costa, 1995, Navicordulia mielkei Machado & Costa, 1995 and Navicordulia miersi Machado & Costa, 1995—were investigated to assess their taxonomic and nomenclatural status. Based on our results the hypothesis of these three nomina corresponding to distinct species is no longer supported. The proportional size of caudal appendages, an additional crossvein in cubito-anal space in the hind wing, as well as minor differences in coloration of pterostigma are not reliable diagnostic characters for supporting their specific status. We consider the three simultaneously available nomina as synonyms, and by action of the first reviser, Navicordulia atlantica Machado & Costa, 1995 is selected as valid nomen, hence N. mielkei syn. nov. and N. miersi syn. nov. are their subjective junior synonyms. Photos, other illustrations, and a new species-level diagnosis are given. Despite of the advances of taxonomic knowledge of Navicordulia, the second species-rich corduliid genus in the Neotropical region, the status of some species still necessitates a full revision.
ABSTRACT
ABSTRACT The small mayfly genus UlmeritusTraver, 1956 currently includes three species of Neotropical Leptophlebiidae (Ephemeroptera) distributed in southern South America in the Pampean and Atlantic Forest dominions: U. carbonelli (Uruguay), U. balteatus (Brazil and Uruguay) and U. saopaulensis (Brazil). Ulmeritus saopaulensis is a poorly known endemic species from Brazil. Based on material from a single locality in Minas Gerais, we complement the knowledge on this species with a redescription of adults and nymphs and describe the eggs for the first time. The confusing nomenclatural history and the correct spelling of the specific name saopaulensis is discussed in light of International Code of Zoological Nomenclature. This paper points out that in despite of recent advances on the knowledge of this genus a full taxonomic review and phylogenetic analyses are pending to solve species delimitation and evolutionary relationships.
ABSTRACT
ABSTRACT Hexapods, commonly known as insects, are a neglected taxonomic group in the Fernando de Noronha archipelago, with unanswered questions about their species richness and the ecological processes in which they are involved (e.g., colonization, introduction, establishment, and extinction). Herein, we provide an updated Hexapod checklist with current nomenclatural combinations. The entomofauna of the Fernando de Noronha archipelago is currently composed of 453 species in 21 orders. The orders, and their respective number of species, are: Blattaria (9), Coleoptera (118), Collembola (29), Dermaptera (3), Diplura (1), Diptera (134), Embioptera (1), Hemiptera (29), Hymenoptera (59), Isoptera (2), Lepidoptera (25), Mantodea (1), Neuroptera (3), Odonata (5), Orthoptera (11), Phasmatodea (1), Phthiraptera (6), Psocoptera (3), Siphonaptera (1), Thysanoptera (10), and Zygentoma (2). The archipelago has 263 new taxon records (family + genera + species). Thirty-eight species (3.39%) were described from local specimens and most of them are likely endemic species. This study more than doubles our knowledge (from the previous 190 records) of the entomofauna in this large Brazilian archipelago. This study also provides a baseline for studies on its conservation status and for implementing future environmental management programs.
ABSTRACT
When rare is just a matter of sampling: Unexpected dominance of clubtail dragonflies (Odonata, Gomphidae) through different collecting methods at Parque Nacional da Serra do Cipó, Minas Gerais State, Brazil. Capture of dragonfly adults during two short expeditions to Parque Nacional da Serra do Cipó, Minas Gerais State, using three distinct collecting methodsaerial nets, Malaise and light sheet trapsis reported. The results are outstanding due the high number of species of Gomphidae (7 out of 26 Odonata species), including a new species of Cyanogomphus Selys, 1873, obtained by two non-traditional collecting methods. Because active collecting with aerial nets is the standard approach for dragonfly inventories, we discuss some aspects of the use of traps, comparing our results with those in the literature, suggesting they should be used as complementary methods in faunistic studies. Furthermore, Zonophora campanulata annulata Belle, 1983 is recorded for the first time from Minas Gerais State and taxonomic notes about Phyllogomphoides regularis (Selys, 1873) and Progomphus complicatus Selys, 1854 are also given.
ABSTRACT
Navicordulia aemulatrix sp. nov. (holotype male deposited in MZSP: Brazil, Santa Catarina State, [São Bento do Sul municipality, 26°14'58"S, 49°22'59"W], [railroad station] Rio Vermelho, II.1952) is described and illustrated based on three males. The long cercus (2.9-3.2 mm) places this species in the longistyla-group together with N. kiautai, N. longistyla and N. nitens but it differs from them mainly by the shape of cercus, with carinated part occupying 0.33 of cercus total length, and also by dorsal, ventro-medial and ventro-lateral tubercles developed. An unusual process on tergal portion of prothorax is reported for the first time in Navicordulia. The rate of description of new species of South American 'Corduliidae' is discussed. A map with records of Atlantic Forest Navicordulia species and a list of Brazilian corduliids by state are also presented.
Navicordulia aemulatrix sp. nov. (holótipo macho depositado no MZSP: Brasil, estado de Santa Catarina, [município de São Bento do Sul, 26°14'58"S, 49°22'59"W], [estação ferroviária] Rio Vermelho, II.1952) é descrita e ilustrada com base em três machos. O cerco longo (2,9-3,2 mm), posiciona esta espécie no grupo longistyla juntamente com N. kiautai, N. longistyla and N. nitens, mas difere delas principalmente pelo formato do cerco, com a parte carenada ocupando 0,33 do comprimento total e também pelos tubérculos dorsal, ventro-mediano e ventro-lateral desenvolvidos. Um processo incomum na porção tergal do protórax é mencionado pela primeira vez em Navicordulia. Além disso, a taxa de descrição de novas espécies Sul-Americanas de 'Corduliidae' é discutida. Um mapa com os registros das espécies de Navicordulia da Mata Atlântica e uma lista por estado dos corduliídeos brasileiros são também apresentados.
