Central American Species

Paper wasps (subfamily Polistinae) are one of the four main groups of eusocial insects in the Neotropics. They are medically important for the frequent stings inflicted on humans, but at the same time are valuable predators of pest insects. Nonetheless, there are no updated keys for the identification of the Central American species. Here we provide keys to the 18 genera and 106 species known to occur in Costa Rica, illustrated with one hundred original line drawings.

Three new species belonging to the tribe Nymphistrini of the obligate myrmeco- and termitophilous subfamily Haeteriinae (Coleoptera: Histeridae) are described from Central America: Nymphister rettenmeyeri sp. n. (Costa Rica and Panama), Trichoreninus carltoni sp. n. (Belize and Honduras) and T. neo sp. n. (Costa Rica and Panama).  Identification keys for the Central American species of both genera are prepared.  Available host records for N. rettenmeyeri confirm the symbiosis of the genus with Eciton army ants: the species has been found in colonies of E. burchelli (Westwood), E. hamatum (Fabricius) and E. mexicanum Roger.  Host records are not available for the new species of Trichoreninus as all known specimens were collected by flight intercept traps.

AbstractThe North and Central American species formerly placed in the genus Mycetoporus are revised. Two genera are recognized, Mycetoporus Mannerheim and Ischnosoma Stephens, each with 18 species. The morphological and historical basis for this division is discussed. Ten species of Mycetoporus are described as new: bipunctatu, floridensis, impunctatus, neomexicanus, nidicola, pacificus, rufohumeralis, segregatus, smetanai, and triangulatus. Ten species of Ischnosoma are described as new: arizonense, ashei, costale, durangoense, fimbriatum, hermani, lecontei, mexicanum, pecki, and suteri. Mycetoporus boreelus J. Sahlberg, a species restricted to the Palearctic region, is removed from synonymy with M. nigrans Mäklin and Mycetoporus insignis Mäklin is found to be a junior synonym of M. americanus Erichson. Mycetoporus discalis, M. punctatissimus, and M. punctulatus, all species described by Hatch (1957), are transferred to the genus Bryoporus subgenus Bryophacis and the name Tachinus humidus Say is treated as a nomen dubium in the genus Mycetoporus.The usage of the generic names Mycetoporus Mannerheim and Ischnosoma Stephens is discussed. The North American species of the genus Mycetoporus are placed in six species groups and those of the genus Ischnosoma are placed in four species groups.A neotype is designated for Mycetoporus nigrans Mäklin and lectotypes are designated for M. americanus Erichson, M. insignis Mäklin, M. tenuis Horn, M. lucidulus LeConte, M. consors LeConte, Ischnosoma pictum (Horn) and I. flavicolle (LeConte). The following species were transferred from Mycetoporus to Ischnosoma and are new combinations: pictum Horn, splendidum Gravenhorst, flavicolle LeConte, virginiense Bernhauer, coxale Sharp, hospitale Fall, californicum Bernhauer and Schubert, and curtipenne Bernhauer.All genera, species groups, and species are described and the species are illustrated with line drawings and scanning electron photomicrographs. Keys are provided to distinguish the genera Mycetoporus and Ischnosoma and for all the species in each genus. The New World distribution of each species is mapped. The biology of each species, if known, is discussed.

Saimiri Oerstedii

Central American squirrel monkeys Saimiri oerstedii are limited to Costa Rica and Panama, and have never been abundant. The Costa Rican population is now decimated. Based on our survey of squirrel monkeys throughout a large portion of the Costa Rican range of this species in 1996, we can confirm that at least 1246 squirrel monkeys remain in 26 spatially dispersed localities. Despite probable undercounts of squirrel monkeys within sites and potentially missed localities, the total population size should be considered far below a size that would provide longterm genetic viability. Deforestation and habitat fragmentation spurred by agricultural and tourism development are the familiar culprits contributing to this decline. Our strong recommendation is that future conservation efforts be targeted at the level of each specific locality, perhaps recruiting local, national and international sponsors. A focused strategy would allow management efforts to be tailored to the circumstances specific to each site and thus allocate scarce resources more efficiently.

La presencia de gluten en alimentos etiquetados como libres de gluten (LG) representa una preocupación para la salud de pacientes celíacos, y personas intolerantes y sensibles a este conjunto de proteínas. Sin embargo, esto no ha sido estudiado aún en países centroamericanos. Por tanto, se investigó la presencia de gluten en alimentos etiquetados LG, manufacturados en Costa Rica y disponibles en el mercado entre los años 2016 y 2017 para determinar así el cumplimiento de las regulaciones nacionales e internacionales. Se ha estipulado que dichos alimentos deben contener <20 ppm de gluten. Un total de 173 productos fueron analizados por inmunoensayo (tres muestras por producto; cada una de un lote diferente) utilizando el kit ELISA RIDASCREEN®. 60 marcas de productos, de 32 compañías diferentes, fueron evaluadas identificando 15 categorías de alimentos LG: productos horneados, premezclas y harinas, snacks, granos y cereales, salsas, productos cárnicos, productos de origen marino, bebidas, productos lácteos, pastas, chocolates, aceites, tortillas y arepas, jaleas y mermeladas y otros. Una muestra de uno de los productos analizados presentó >20 ppm de gluten. No obstante, al menos una muestra de 49 productos diferentes (28% de los productos analizados) presentó una concentración cuantificable de gluten (>5 ppm) evidenciando una alta variabilidad en los resultados. Esta investigación evidencia el fuerte compromiso de la industria alimentaria costarricense para cumplir la norma que regula la producción de alimentos LG durante el período de estudio, aunque se alerta acerca de la necesidad de implementar mejoras en los sistemas de producción y vigilancia de estos alimentos. The presence of gluten in gluten free (GF) labelled foods represents a serious health concern to celiac patients and persons intolerant or sensitive to this set of proteins. However, this has not yet been studied in Central American countries. Therefore, the presence of gluten in foods labeled LG, manufactured in Costa Rica and available in the market, between 2016 and 2017, was investigated to determine compliance with national and international regulations. It has been stipulated that such foods must contain <20 ppm of gluten. A total of 173 products were analyzed by immunoassay (three samples per product; each from an independent batch), using the ELISA RIDASCREEN® kit. 60 product brands, from 32 different companies, were evaluated and 15 GF food categories were identified: baked products, baking mixes and flours, snacks, grains and cereals, sauces, meat products, seafood, beverages, dairy products, pasta, chocolates, oils, tortillas and arepas, jams and jellies, and others. Only one sample from one of the tested products presented >20 ppm of gluten. However, at least one sample of 49 different products (28% of products tested) presented a quantifiable concentration of gluten (>5 ppm), showing a high variability of results. This research evidences the strong commitment of the Costa Rican food industry to comply with the norm that regulates the production of LG foods during the study period, even though it warns about the need to implement improvements in the production and surveillance systems of these foods.
