13. Molecular detection of adulteration in commercial buffalo meat products by multiplex PCR assay
Abstract Authentication of commercial buffalo meat products has become a market concern. This study intended to develop and validate a highly species-specific multiplex PCR assay for authentication of buffalo meat products. Four pairs of species-specific primers were used to target mitochondrial cytochrome oxidase I (COI) gene. The assay generated the expec

14. Molecular characterization of Moenkhausia (Pisces: Characiformes) populations with different lateral line developmental levels
ABSTRACT The genera Hemigrammus and Moenkhausia have been traditionally diagnosed mainly by the former having lateral line completely pored whereas the latter having a lateral line with a few pored scales. Those features have been used to diagnose species of both genera in the upper Paraná River floodplain. Specimens with the diagnostic features of Moenkhau

15. Efficient detection of Frankliniella schultzei (Thysanoptera, Thripidae) by cytochrome oxidase I gene (mtCOI) direct sequencing and real-time PCR
ABSTRACT Identification of Thysanoptera is based mainly on external morphology examination that can be time-consuming and difficult for non taxonomic experts. In this work, we propose a rapid and efficient molecular method to identify Frankliniella schultzei, an important and widespread pest thrips vector of tospoviruses in South America countries. Species-s

16. The exotic jumping snail Ovachlamys fulgens (Gude, 1900) (Gastropoda: Helicarionidae) in urban areas of the Upper-Paraná Atlantic Forest
ABSTRACT The exotic land gastropod Ovachlamys fulgens (Gude, 1900), aka the jumping snail, was registered in Eldorado city, Misiones province, constituting the first documented record of that species in Argentina-and for all of South America as well. Identities of the individuals were confirmed through morphological examination, and by a DNA sequencing of th

17. Color patterns of the hermit crab Calcinus tibicen (Herbst, 1791) fail to indicate high genetic variation within COI gene
Abstract Apart from traditional characters, other data have been used for taxonomy, like color patterns. Based on the different colors (green and orange) observed for some Calcinus tibicen (Herbst, 1761) specimens, we evaluated the genetic distance for cytochrome oxidase subunit I mitochondrial gene of individuals collected in Pernambuco (northern Brazil) an

18. Stranded humpback whale (Megaptera novaeangliae) (Cetacea: Balaenopteridae) in Paraná River Delta, Buenos Aires Province, Argentina. Comments on the occurrence of marine mammals in the La Plata River Basin
Abstract The humpback whale (Megaptera novaeangliae) is distributed among most oceans and seas of the globe (except Mediterranean Sea). These whales migrate from feeding regions in the Antarctic waters to breeding areas in tropical and subtropical seas. Here we report the stranding of a female young humpback whale, which was founded dead in the vicinity of t

19. Genetic divergence of a newly documented population of the cecidogenous micromoth Eugnosta azapaensis Vargas & Moreira (Lepidoptera: Tortricidae) in the Atacama Desert of northern Chile
Abstract Eugnosta azapaensis Vargas and Moreira, 2015 (Lepidoptera: Tortricidae) is a micromoth native to the Atacama Desert whose larvae induce fusiform galls in shoots of Baccharis salicifolia (Ruiz & Pav.) Pers. (Asteraceae). The presence of this cecidogenous tortricid was previously recorded only from the type locality, the Azapa Valley, Arica Province,

20. REDESCRIPCIÓN DE POTAMOLITHUS SUPERSULCATUS PILSBRY, 1896 (GASTROPODA, TATEIDAE) DEL SUR DE LA CUENCA DEL PLATA
ABSTRACT The genus Potamolithus Pilsbry, 1896 (Gastropoda; Tateidae), has 31 species, 22 of which are distributed in Argentina in Del Plata basin, defining the Uruguay River and the Río de la Plata as a “hotspot” of diversity in freshwater gastropods. However, most of its species has been described only by conchology characters and a few has anatomical

21. New primers for amplification of cytochrome c oxidase subunit I barcode region designed for species of Decapoda (Crustacea)
Abstract We designed 14 new primers for amplification of the COI barcode region of decapod crustacean species. We tested, with high level of success, the generation of ~ 640 ± 49 base-pair sequences in selected groups of decapods (hermit crabs, squat lobsters, marine and freshwater crabs and shrimps), encompassing representatives of 27 genera of 15 families

22. 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

ABSTRACT The external morphology of immature stages of Zaretis strigosus (Gmelin, [1790]) and Siderone galanthis catarina Dottax and Pierre, 2009 comb. nov. from southern Brazil are described. Additionally, morphology of the adults and sequences of the mitochondrial gene cytochrome oxidase, subunit I, were analyzed in order to evaluate the taxonomy of Sidero

24. 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
