13. DNA barcoding reveals the diversity of sharks in Guyana coastal markets
RESUMO Um desafio fundamental para a pesca sustentável e a proteção da biodiversidade nos neotrópicos é a identificação precisa das espécies. A biodiversidade dos tubarões costeiros da Guiana é pouco compreendida, porém essas espécies estão sujeitas tanto à pesca artesanal quanto à pesca industrializada não costeira. Para determinar quais esp

14. Molecular and taxonomic characterisation of introduced specimens of Poecilia reticulata in the lower Paraguay River basin (Cyprinodontiformes: Poeciliidae)
RESUMO Poecilídeos compreendem cerca de 300 espécies que habitam águas doces e salobras das Américas e África. Poecilia reticulata é nativa do nordeste da América do Sul e Trinidad e Tobago. Neste trabalho, espécimes introduzidos de P. reticulata coletados no baixo rio Paraguai na Argentina, foram caracterizados por meio de abordagens moleculares e t

15. IDENTIFICAÇÃO MOLECULAR DE Liriomyza sp. NAS REGIÕES NORDESTE E SUDESTE DO BRASIL
RESUMO No Brasil, as espécies do gênero Liriomyza têm importância econômica e são amplamente distribuídos no país, causando danos a pelo menos 14 famílias de plantas, especialmente Solanaceae, Cucurbitaceae, Asteraceae e Fabaceae. Estudos sugerem a existência de um complexo de espécies dentro deste gênero com base na presença de semelhança morf

16. Distribution, habitat use and plant associations of Moluchia brevipennis (Saussure, 1864) (Blattodea: Ectobiidae): an endemic cockroach from Chilean Mediterranean Matorral biome
ABSTRACT Wild cockroaches are often described as abundant and diverse insects from wet tropical zones; however, they can also be found in arid and semiarid areas. It is proposed that in these drier environments cockroach survival may dependent on its tight association with native plant species. In this work, using bait trapping and active collection methods,

17. DNA barcoding confirms the occurrence of Rhamdia branneri and Rhamdia voulezi (Siluriformes: Heptapteridae) in the Iguaçu River Basin
RESUMO O DNA barcoding é uma ferramenta molecular precisa para a identificação de espécies e resoluções taxonômicas. Até recentemente, Rhamdia voulezi e Rhamdia branneri eram consideradas sinônimas de Rhamdia quelen, contudo caracteres morfológicos e citogenéticos têm apontado à validade de ambas. Devido à escassez de informações sobre a taxo

18. Two new species of Mycodrosophila (Diptera, Drosophilidae) proposed by molecular and morphological approaches, with a key to American species
ABSTRACT There are approximately 130 species of MycodrosophilaOldenberg, 1914 worldwide, although only nine species were recorded in American countries so far, three of which are exclusively Nearctic, five exclusively Neotropical and one found in both biogeographic regions (Mycodrosophila projectans). Such a small number of American species is likely a conse

19. Redescrição de Campoletis sonorensis (Cameron, 1886) (Hymenoptera, Ichneumonidae, Campopleginae), parasitoide de Spodoptera frugiperda (J. E. Smith, 1797) (Lepidoptera, Noctuidae) no Brasil
Resumo Spodoptera frugiperda é uma praga voraz de diversas culturas de importância econômica no Novo Mundo. No Brasil, suas larvas podem ser atacadas por diversas espécies de vespas parasitóides que são candidatos a agentes de controle biológico contra essa praga. Pesquisando os parasitóides da fauna de Spodoptera frugiperda em cultivos de milho no B

20. Cytogenetics and DNA barcoding of the Round-eared bats, Tonatia (Chiroptera: Phyllostomidae): a new karyotype for Tonatia bidens
ABSTRACT There are two species of Neotropical Round-eared bats, Tonatia bidens Spix, 1823 and Tonatia saurophila Koopman & Williams, 1951, which present highly similar morphological characteristics that can lead to errors of identification. Specimens originally identified as T. bidens have recently been reclassified as T. saurophila, and the only karyotype d

21. First report of brown widow spider sightings in Peninsular Malaysia and notes on its global distribution
Abstract Background: The brown widow spider (
Latrodectus geometricus Koch, 1841) has colonised many parts of the world from its continent of origin, Africa. By at least 1841, the species had successfully established populations in South America and has more recently expanded its range to the southern stateJ. Venom. Anim. Toxins incl. Trop. Dis.

22. Morphometric variation of the Herichthys bartoni (Bean, 1892) species group (Teleostei: Cichlidae): How many species comprise H. labridens (Pellegrin, 1903)?
Cichlids of the tribe Heroini have long been a source of taxonomical conflict. In particular, the species included in the Herichthys bartoni group have failed to be recovered as monophyletic in different molecular studies. In this paper we use traditional and geometric morphometrics to evaluate morphological variation in the species included in the H. barton

23. Genetic identification of bucktooth parrotfish Sparisoma radians (Valenciennes, 1840) (Labridae, Scarinae) by chromosomal and molecular markers
Parrotfishes (Labridae, Scarinae) comprise a large marine fish group of difficult identification, particularly during juvenile phase when the typical morphology and coloration of adults are absent. Therefore, the goal of this study was to test cytogenetic markers and DNA barcoding in the identification of bucktooth parrtotfish Sparisoma radians from the nort

24. DNA barcoding in Atlantic Forest plants: what is the best marker for Sapotaceae species identification?
The Atlantic Forest is a phytogeographic domain with a high rate of endemism and large species diversity. The Sapotaceae is a botanical family for which species identification in the Atlantic Forest is difficult. An approach that facilitates species identification in the Sapotaceae is urgently needed because this family includes threatened species and valuab
