Introducción. El gusano barrenador del ganado, Cochliomyia hominivorax (Coquerel), es una plaga de importancia económica para animales de sangre caliente, principalmente el ganado vacuno. Objetivo. Caracterizar molecularmente seis cepas de Cochliomyia hominivorax (Coquerel) y la especie Cochliomyia macellaria, por medio de las secuencias del mtADN. Materiales y métodos. El estudio se realizó durante los años 2006 y 2007, utilizando seis cepas de colonias procedentes de México, Panamá y Costa Rica, ubicadas en el Laboratorio de Biología Molecular del Instituto Smithsonian de Investigaciones Tropicales, Panamá. Se optimizaron tres cebadores de seis que fueron evaluados, por medio del método de secuenciación cíclica. Para establecer las relaciones filogenéticas entre las cepas se realizaron los análisis de Parsimonia, NJ (Neighbor-Joining), Máxima Verosimilitud y Bayesiano. Para C. macellaria se evaluaron tres cebadores que fueron utilizados para C. hominivorax. Resultados. Se obtuvieron las regiones del genoma mitocondrial NADH4–tRNA–NADH5. Todos los análisis mostraron la misma topología formando cuatro clados definidos. El primero formado por las cepas de Oaxaca y Quintana Roo, el segundo por las cepas de Chiapas, el tercero por las cepas de Costa Rica y Panamá y el cuarto por la población de Brasil, obtenida de GenBank. En C. macellaria dos cebadores lograron amplificar la región NADH4 y uno la región NADH5. Conclusión. Las amplificaciones obtenidas en esta investigación aportan información para continuar con los estudios moleculares entre las especies de C. macellaria y C. hominivorax; también para identificar el origen geográfico de las cepas.

We estimated the genetic diversity of 50 Jatropha curcas Costa Rican samples using 18 EST-SSR, one G-SSR and nrDNA-ITS markers. We also evaluated the phylogenetic relationships among samples using nuclear ribosomal ITS markers. Non-toxicity was also evaluated using G-SSRs and SCARs markers. A Neighbor-Joining (NJ) tree and a Maximum Likelihood (ML) tree were constructed using SSR markers and ITS sequences, respectively. Heterozygosity was moderate (He = 0.346), but considerable when compared to worldwide values for J. curcas. The PIC (PIC = 0.276) and inbreeding coefficient (f = -0.102) were both low. Clustering was not related to the geographical origin of accessions but Costa Rican J. curcas consistently clustered as a separate group. International accessions clustered independently of collection sites suggesting a lack of genetic structure, probably due to a wide distribution of this crop and ample gene flow. Molecular markers identified only one non-toxic accession (JCCR-24) from Mexico. This work is part of a countrywide effort to characterize the genetic diversity of Jatropha curcas germplasm bank in Costa Rica.

Testudines is the crown-group that includes all living forms of turtles and their closest relatives. This group is known from the late Triassic and persists to this day. The fossil record of Testudines in Mexico is scarce and has been previously compiled in several papers. Here we present an update including all osteological and ichnological records from México and Central America. In Mexico, the Testudines fossil record extends from the Late Triassic to the Pleistocene, being widely abundant during the Pleistocene. Kinosternon and Gopherus are the best represented taxa, known from the late Miocene (Hemphillian) to the late Pleistocene (Rancholabrean). Fossil turtles are well represented in Mexico, excluding the states of Campeche, Mexico City, Colima, Guerrero, Queretaro, Quintana Roo and Sinaloa. On the contrary, the ichnological records are only known in Coahuila, Puebla and Zacatecas. In Central America there are records of fossil turtles in El Salvador, Honduras, Costa Rica and Panama, the latter being the country holding most records. Finally, nine new species have been described in the region, six for Mexico (Notoemys tlaxiacoensis, Yelmochelys rosarioae, Mexichelys coahuilaensis, Gopherus donlaloi, G. auffenbergi and G. pargensis, of which G. auffenbergi is synonymous with G. berlandieri and G. pargensis is considered a nomen vanum) and three in Central America (Rhinoclemmys nicoyama from Costa Rica, and Rhinoclemmys panamaensis and Staurotypus moschus from Panama).

The Neotropical family Mesembrinellidae is revised. A total of 53 valid, extant species are included in the family, including 15 described as new and 38 redescribed based on study of type and non-type material and of the literature. A total of 18 primary types were examined. An additional ca. 2300 specimens, belonging to 47 species, were studied in detail, including dissection and photographic documentation of terminalia, with many females illustrated for the first time. Keys to subfamilies, genera, species-groups and species are provided. Type specimens of six species housed in South American institutions could not be obtained for study, i.e., M. bequaerti Séguy, 1925 and the five recently described species M. andina (Wolff et al., 2014), M. carvalhoi (Wolff et al., 2013b), M. cordillera (Wolff & Ramos-Pastrana in Wolff et al., 2017), M. obscura (Wolff in Wolff et al., 2017) and Laneella patriciae (Wolff, 2013). We accept the synonymy, proposed by previous authors, of Eumesembrinella Townsend, 1931 with Mesembrinella Giglio-Tos, 1893. In addition, we synonymize the genera Albuquerquea Mello, 1967, Giovanella Bonatto in Bonatto & Marinoni, 2005, Henriquella Bonatto in Bonatto & Marinoni, 2005, Huascaromusca Townsend, 1918 and Thompsoniella Guimarães, 1977 with Mesembrinella Giglio-Tos, 1893, synn. nov., retaining three valid genera in the family: Laneella Mello, 1967, Mesembrinella and Souzalopesiella Guimarães, 1977. Laneella nigripes Guimarães, 1977 and Mesembrinella bellardiana Aldrich, 1922 are fixed as the type species of the genera Laneella Mello, 1967 and Mesembrinella Giglio-Tos, 1893, respectively, under Article 70.3 of the ICZN Code. We separate Mesembrinella into the following species-groups: M. latifrons (Mello, 1967), M. spicata Aldrich, 1925, M. bolivar (Bonatto in Bonatto & Marinoni, 2005), M. aeneiventris (Wiedemann, 1830), M. bicolor (Fabricius, 1805), and M. anomala (Guimarães, 1977). The following 15 new species are described: Laneella fusconitida Whitworth, sp. nov. from Costa Rica, Ecuador and Venezuela, Laneella fuscosquamata Whitworth, sp. nov. from Guatemala and Mexico, Laneella purpurea Whitworth, sp. nov. from Costa Rica, Mesembrinella bullata Whitworth, sp. nov. from Bolivia, Mesembrinella chantryi Whitworth, sp. nov. from French Guiana and Brazil, Mesembrinella epandrioaurantia Whitworth, sp. nov. from Venezuela, Mesembrinella guaramacalensis Whitworth, sp. nov. from Venezuela, Mesembrinella longicercus Whitworth, sp. nov. from Bolivia, Mesembrinella mexicana Whitworth, sp. nov. from Mexico, Mesembrinella nigrocoerulea Whitworth, sp. nov. from Costa Rica, Ecuador and Venezuela, Mesembrinella serrata Whitworth, sp. nov. from Peru, Mesembrinella velasquezae Whitworth, sp. nov. from Venezuela, Mesembrinella violacea Whitworth, sp. nov. from Costa Rica, Mesembrinella woodorum Whitworth, sp. nov. from Ecuador, and Mesembrinella zurquiensis Whitworth, sp. nov. from Costa Rica. Mesembrinella abaca Hall, 1948 is proposed as a junior synonym of Mesembrinella socors (Walker, 1861), syn. nov. Lectotypes are designated for Dexia randa Walker, 1849 (now Mesembrinella) and Mesembrinella pictipennis Aldrich, 1922. We analyze the most extensive DNA-barcode dataset for Mesembrinellidae to date, encompassing the three genera considered valid and including 188 sequences (178 new) from 35 species, with data for 23 species provided for the first time. The topology of the resulting Neighbor-Joining tree is mostly congruent with morphology; however, some species show considerable genetic variation that is not reflected by morphology. Finally, we include a corrigendum to the recent Zootaxa paper on Nearctic Calliphora Robineau-Desvoidy (Diptera: Calliphoridae) by Tantawi et al.

Trata-se de um estudo epidemiológico descritivo com o objetivo de avaliar a ocorrência de miíases humanas em áreas urbanas de quatro municípios do Estado do Rio de Janeiro. Foram analisados 71 pacientes que procuraram espontaneamente o atendimento em Postos de Saúde, no período de outubro de 1999 a outubro de 2003. Maior prevalência da doença foi encontrada em adultos e idosos acima de 51 anos (42,3%) e em menores de 10 anos (33,8%). Do total dos casos estudados, 62% incluíam-se no nível sócio-econômico baixo; 60,6% eram do sexo masculino e 33,8% dos indivíduos infestados, sem profissão. Nos casos analisados as espécies bioagentes foram Cochliomyia hominivorax (Coquerel, 1858); Dermatobia hominis (Linnaeus Jr, 1781) e Cochliomyia macellaria (Fabricius, 1775). Os resultados apontam para a associação da doença com as condições de vida e de higiene dos pacientes, sinalizando para a necessidade de atenção mais específica à saúde dos grupos mais vulneráveis.
