          Abstract

          Abstract An updated checklist of the caddisflies from the State of Oaxaca, Mexico is presented, based primarily on a bibliographic review. Fourteen families, 44 genera and 216 species of caddisflies have been recorded, 38 (17.51%) of which are endemic, and 9 species are recorded for the first time from Oaxaca. For each species, we describe its geographic distribution, provide references with distribution records, and highlight those that are endemic to Oaxaca and Mexico. Although there has been a significant increase in taxonomic work on Mexican caddisflies, it is still necessary to continue studying the systematics, ecology, and biogeography of Trichoptera from Oaxaca, especially in poorly explored regions.

          Resumen Se presenta una lista actualizada de los tricópteros del estado de Oaxaca, México, basada principalmente en una revisión bibliográfica. Se registraron 14 familias, 44 géneros y 216 especies de tricópteros, de las cuales 38 (17.51%) son endémicas y 9 especies se registran por primera vez para Oaxaca. Para cada especie describimos su distribución geográfica, proporcionamos referencias con registros de distribución y destacamos aquellas que son endémicas de Oaxaca y México. Aunque ha habido un incremento significativo en los trabajos taxonómicos sobre los tricópteros mexicanos, aún es necesario continuar estudiando la sistemática, ecología y biogeografía de los Trichoptera de Oaxaca, especialmente en las regiones poco exploradas.

          Mexican biogeographic provinces: Map and shapefiles

          We provide a map of the 14 biogeographic provinces of Mexico based on the ecoregions recognized for the country, which combine climatic, geological and biotic criteria. These provinces belong to the Nearctic region (Californian, Baja Californian, Sonoran, Chihuahuan Desert and Tamaulipas provinces), Neotropical region (Pacific Lowlands, Balsas Basin, Veracruzan and Yucatán Peninsula provinces) and the Mexican transition zone (Sierra Madre Occidental, Sierra Madre Oriental, Transmexican Volcanic Belt, Sierra Madre del Sur and Chiapas Highlands provinces). In order to facilitate future biogeographic analyses, we provide a file of the biogeographical regionalisation of Mexico by converting the map into a polygon shapefile and a raster file with all provinces. We also separately provide each of the provinces in vector and raster format. All the maps are in geographical and Lambert Conformal Conic projections.

            Catalog of the Neotropical Trichoptera (Caddisflies)

            Abstract The Neotropical caddisfly ( Trichoptera ) fauna is cataloged from a review of over 1,000 literature citations through 2015 (partial 2016) to include 3,262 currently recognized, valid species-group names in 25 families and 155 extant genera. Fourteen subspecies are included in the total as well as 35 fossil species and 1 fossil genus. The region covered includes all of Mexico, Central America, the Caribbean, and South America. Genus-group and species-group synonyms are listed. For each nominal species, information on the type locality, type depository, sex of type, distribution by country, and other pertinent taxonomic or biological information is included. Summary information on taxonomy, phylogeny, distribution, immature stages, and biology are provided for each family and genus where known. An extensive index to all nominal taxa is included to facilitate use of the catalog. The glossosomatid species Mexitrichia usseglioi Rueda Martín & Gibon, is transferred to Mortoniella comb. n.

              Diversity and Ecosystem Services of Trichoptera

              The holometabolous insect order Trichoptera (caddisflies) includes more known species than all of the other primarily aquatic orders of insects combined. They are distributed unevenly; with the greatest number and density occurring in the Oriental Biogeographic Region and the smallest in the East Palearctic. Ecosystem services provided by Trichoptera are also very diverse and include their essential roles in food webs, in biological monitoring of water quality, as food for fish and other predators (many of which are of human concern), and as engineers that stabilize gravel bed sediment. They are especially important in capturing and using a wide variety of nutrients in many forms, transforming them for use by other organisms in freshwaters and surrounding riparian areas. The general pattern of evolution for trichopteran families is becoming clearer as more genes from more taxa are sequenced and as morphological characters are becoming understood in greater detail. This increasingly credible phylogeny provides a foundation for interpreting and hypothesizing the functional traits of this diverse order of freshwater organisms and for understanding the richness of the ecological services corresponding with those traits. Our research also is gaining insight into the timing of evolutionary diversification in the order. Correlations for the use of angiosperm plant material as food and case construction material by the earliest ancestors of infraorder Plenitentoria—by at least 175 Ma—may provide insight into the timing of the origin of angiosperms.
