ABSTRACTThis paper deals with the occurrence of the species Notarius bonillai (Miles, 1945) in waters of Ilha do Maranhão (or Ilha de São Luís), Maranhão, Brazil. The investigation is necessary to clarify the distribution of this species before any regional study on it can be made. In seven previous studies, Notarius bonillai is mentioned as living in waters of this region: in São José Bay at east, São Marcos Bay at west, and Arraial bay at south. However, several studies in South America report the species as endemic of the  two rivers and their estuaries, which flow into the coast of the Caribbean Sea of Colombia. Analysis included preserved specimens identified as Notarius bonillai from a regional fish collection of Ilha do Maranhão. Additional material of Cathorops specimens were collected in the municipality of Raposa, located near estuary of rio Paciência in the east of Ilha do Maranhão. Analysis of the morphological characters of preserved specimens of the regional fish collection, indicate that the species identified as Notarius bonillai in the region was erroneously identified, instead being Cathorops arenatus (Valenciennes, 1840). Morphological analysis of the additional material collected from Cathorops specimens indicate three species of Cathorops occurring in Ilha do Maranhão: Cathorops agassizii (Eigenmann & Eigenmann, 1888), Cathorops arenatus (Valenciennes, 1840), and Cathorops spixii (Agassiz, 1829). Consequently, Notarius bonillai does not occur in Ilha do Maranhão. RESUMOEste trabalho trata da ocorrência da espécie Notarius bonillai (Miles, 1945) na Ilha do Maranhão (ou Ilha de São Luís), Maranhão, Brasil. A investigação é necessária para esclarecer a distribuição desta espécie antes que qualquer estudo regional sobre ela possa ser feito. Em sete estudos anteriores,Notarius bonillai é mencionado como vivendo nas águas desta região: na Baía de São José a leste, na Baía de São Marcos a oeste e na Baía de Arraial ao sul. No entanto, vários estudos na América do Sul relatam a espécie como endêmica de dois rios e seus estuários, que desembocam na costa do Mar do Caribe na Colômbia. Análises incluíram espécimes preservados como Notarius bonillai deuma coleção regional de peixes da Ilha do Maranhão. Material adicional de espécimes de Cathorops foram coletados no município de Raposa, localizado próximo ao estuário do rio Paciência, no leste da Ilha do Maranhão. A análise dos caracteres morfológicos dos espécimes preservados na coleção regional de peixes, indicam que a espécie identificada como Notarius bonillai na região foierroneamente identificada, sendo Cathorops arenatus (Valenciennes, 1840) sua correta identificação. Análises morfológicas do material adicional de espécimes de Cathorops coletados indicam três espécies de Cathorops com ocorrência na Ilha do Maranhão: Cathorops agassizii (Eigenmann & Eigenmann, 1888), Cathorops arenatus (Valenciennes, 1840) e Cathorops spixii (Agassiz, 1829).Consequentemente, Notarius bonillai não ocorre na Ilha do Maranhão.Palavras-chave: Estuários; Nueva Granada sea catfish; Bagre cabezón; Uriacica; Baía de São Marcos; Baía de São José.

 “Fishtail” or just “Fell” points represent an excellent marker to know and discuss the existence of colonizers hunter-gatherers living in Central and South America during the end of the Pleistocene at about 11000-10000 14C yr BP. Investigations of Venezuelan fishtail points yielded additional data on their manufacturing procedure to help discuss the human colonization of northern South America. The finds from northern Venezuela on the Caribbean Sea yielded a link arguing for the use of the Atlantic slope and the current continental shelf during human dispersal in South America.“Rabo de peixe” ou somente pontas Fell representam um excelente indicador para conhecer e discutir a existência de colonizadores caçadores-coletores que viveram na América Central e do Sul durante o final do Pleistoceno há aproximadamente 11.000-10.000 14C anos AP. Pesquisas com pontas Rabo de peixe da Venezuela proporcionaram dados adicionais sobre o seu processo de fabricação contribuindo na discussão da colonização humana do norte da América do Sul. As descobertas do norte da Venezuela no Mar do Caribe defendem a utilização da vertente Atlântica e da plataforma continental atual durante a dispersão humana na América do Sul.

Pomatostegus Schmarda, 1861 is a serpulid genus with three recognized species, mostly from tropical waters. Pomatostegus stellatus (Abildgaard, 1789), was described from the Caribbean Sea, and has been widely recorded in the Pacific and Indian oceans; P. kroyeri Mörch, 1863 was described from Puntarenas, Costa Rica; however, most records from the Tropical Eastern Pacific were referred to P. stellatus. In this work, the two species are redescribed using morphological characters. The main differences are in the shape of the Spirobranchus-type collar chaetae, opercular plate shape and the number of “free” circlets of spines without accompanying of opercular plates. Comments about characters of P. actinoceras Mörch, 1863, described from Philippines, and an identification key for the three species, are included.

The genus Pyura is widely distributed with 99 valid species. Since 1961, Pyura vittata (Stimpson, 1852) has been reported to the Southwest Atlantic but new collections and a revision of the morphological characters of samples deposited in scientific collections revealed that samples had been confused with two other species: Pyura gangelion (Savigny, 1816) and Pyura beta sp. nov. present in the Caribbean sea and Brazil. In Brazil, P. vittata is not present south to Bahia, P. beta was found from Espírito Santo to São Paulo, while P. gangelion was only found in Espírito Santo, and we suggest that populations of both P. beta and P. gangelion are non-native in Brazil.

The identification of the lebranche mullet in the western south Atlantic has long been problematical. In most recent works either Mugil liza Valenciennes and M. platanus Günther, 1880 or M. liza and M. cephalus Linnaeus, 1758 were recognized from the region and more rarely the occurrence of only one species has been proposed but without sufficient morphological, biochemical or molecular data to allow the designation of the taxonomically appropriate name. Analysis of meristic and morphometric data taken from samples collected from Venezuela to Argentina, clearly indicates that there is only one species of lebranche mullet in the Caribbean Sea region and the Atlantic coast of South America and that Mugil liza is the appropriate name. The comparison of the combined data from all the samples of M. liza with the data taken from one sample of M. cephalus that originated in the Mediterranean, the possible locality from which type specimens were collected (Eschmeyer and Fricke, 2009), revealed significant differences indicating that they are different species. It is also suggested that individuals from the western north Atlantic identified as M. cephalus might represent a population of M. liza in this region.

Redefinition of the cicada tribe Hemidictyini Distant, 1905, status of the tribe Iruanini Boulard, 1993 rev. stat., and the establishment of Hovanini n. tribe and Sapantangini n. tribe (Hemiptera: Cicadidae)

A recent paper by Ruschel & Campos (2019) on “leaf-winged” cicadas proposed a significant reorganization of the cicada tribe Hemidictyini Distant, 1905g, including synonymization of the monogeneric tribe Lacetasini Moulds & Marshall, 2018 following the results of a cladistic parsimony analysis of morphological characters. In this study, we reconsider and revise the morphological analysis of Ruschel & Campos and obtain new genetic data for Hemidictya. We find that their study suffers from a limited taxon sample, inappropriate outgroup selection, and misinterpretation of genitalic characters (uncus vs. claspers). We show that Hemidictyini sensu Ruschel & Campos includes members of multiple tribes and subfamilies, and we conclude that some of the taxonomic transfers by Ruschel & Campos are not supported. The two most similar and leaf-like cicadas, Hemidictya Burmeister, 1835 (South America) and Hovana Distant, 1905g (Madagascar), are probably not closely related but rather an excellent example of convergent evolution. Lacetasini is not a junior synonym of the Hemidictyini but a distinct part of the Tettigomyiinae Distant, 1905g as originally classified. We return or transfer the genera Lacetas Karsch, 1890, Iruana Distant, 1905g, Bafutalna Boulard, 1993, and Murphyalna Boulard, 2012 to the Lacetasini. With the transfer of all genera of Iruanina Boulard, 1993 and Bafutalnina Boulard, 1993 to Lacetasini and with Lacetas transferred to the Iruanina, Lacetasini n. syn. becomes a subjective junior synonym of Iruanini rev. stat. in the Tettigomyiinae. We assign Hovana to Hovanini n. tribe in the Tettigomyiinae and Sapantanga Distant, 1905g to Sapantangini n. tribe in the Tibicininae Distant, 1905b. We propose that Hemidictyini sensu novo contains only the genus Hemidictya and we assign the tribe to Tibicininae with a revised diagnosis.

Recent Bottleneck

ABSTRACT Coccidioides posadasii is a pathogenic fungus that causes coccidioidomycosis in many arid regions of the Americas. One of these regions is bordered by the Caribbean Sea, and the surrounding landscape may play an important role in the dispersion of C. posadasii across South America through southeastern Mexico, Honduras, Guatemala, and Venezuela. Comparative phylogenomic analyses of C. posadasii reveal that clinical strains from Venezuela are genetically distinct from the North American populations found in (i) Arizona and (ii) Texas, Mexico, and the rest of South America (TX/MX/SA). We find evidence for admixture between the Venezuela and the North American populations of C. posadasii in Central America. Additionally, the proportion of Venezuelan alleles in the admixed population decreases as latitude (and distance from Venezuela) increases. Our results indicate that the population in Venezuela may have been subjected to a recent bottleneck and shows a strong population structure. This analysis provides insight into potential for Coccidioides spp. to invade new regions. IMPORTANCE Valley Fever is a fungal disease caused by two species of fungi: Coccidioides immitis and C. posadasii. These fungi are found throughout the arid regions of North and South America; however, our understanding of genetic diversity and disease in South America is limited. In this report, we analyze 10 new genomes of Coccidioides posadasii from regions bordering the Caribbean Sea. We show that these populations are distinct and that isolates from Venezuela are likely a result of a recent bottleneck. These data point to patterns that might be observed when investigating recently established populations.
