The global EPTO database: Worldwide occurrences of aquatic insects
Grigoropoulou, Afroditi; Hamid, Suhaila Ab; Acosta, Raúl; Akindele, Emmanuel Olusegun; Al‐Shami, Salman A.; Altermatt, Florian; Amatulli, GiuseppeMotivation: Aquatic insects comprise 64% of freshwater animal diversity and are widely used as bioindicators to assess water quality impairment and freshwater ecosystem health, as well as to test ecological hypotheses. Despite their importance, a comprehensive, global database of aquatic insect occurrences for mapping freshwater biodiversity in macroecological studies and applied freshwater research is missing....
Pervasive gaps in Amazonian ecological research
Carvalho, Raquel L.; Resende, Angelica F.; Barlow, Jos; França, Filipe M.; Moura, Mario R.; Maciel, Rafaella; Alves-Martins, Fernanda; Shutt, JackBiodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain underst...
Leptohyphidae (Insecta: Ephemeroptera) from Northeastern Brazil
Cruz, Paulo Vilela; Belmont, Enide Luciana Lima; Boldrini, Rafael; Hamada, NeusaNew records of Leptohyphidae for Northeastern Brazil are provided. Previously, only Tricorythopsis bahiensis Dias, Salles & Ferreira had been recorded in this region, but we now record one species of Amanahyphes Salles & Molineri, one of Leptohyphes Eaton, three of Traverhyphes Molineri, three of Tricorythodes Ulmer, and seven of Tricorythopsis Traver. Two of these species are recorded for the first time in Bra...
Baetidae (Insecta: Ephemeroptera) from northeastern Brazil
Boldrini, Rafael; Cruz, Paulo Vilela; Salles, Frederico Falcaõ; Belmont, Enide Luciana Lima; Hamada, NeusaNew records and notes on the distribution of the family Baetidae are presented. The following genera are reported for this region: Americabaetis, Apobaetis, Aturbina, Baetodes, Callibaetis, Camelobaetidius, Cloeodes, Cryptonympha, Guajirolus, Paracloeodes, Rivudiva, Spiritiops, Waltzoyphius and Zelusia. With the results of the present study, the Northeast Region of Brazil ceases to be one of Brazil's five geogr...
A new genus and species of Baetidae (Insecta: Ephemeroptera) from Brazil
Cruz, Paulo Vilela; Salles, Frederico Falcaõ; Hamada, NeusaA new genus (Callibaetoides) and species (Callibaetoides caaigua) of Baetidae (Ephemeroptera) is described based on nymphs and adults of both genders collected in forested areas of Amazonia and Mata Atlântica biomes. The nymphs were collected from leaf packs accumulated in the backwaters of small streams. The genus and species can be easily distinguished from other members of the family in South America by the ...
New Baetidae (Insecta: Ephemeroptera) records from Venezuela and nymph descript...
Cruz, Paulo Vilela; Boldrini, Rafael; Quinto, Carlos F.; Frontado, Hortencia L.The Ephemeroptera fauna in Venezuela is poorly known, as is also the case in others areas in South America. Recently, two studies increased from 33 to 50 the number of species recorded in Venezuela. The objective of the present study is to report for the first time in Venezuela the following species: Baetodes levis; Camelobaetidius edmundsi; Fallceon sp.; Mayobaetis ellenae. The nymph of Fallceon sp. is describ...
Taxonomy: A new species of Tricorythodes Ulmer (Ephemeroptera: Leptohyphidae) f...
Días, Lucimar Gomes; Cruz, Paulo Vilela; Ferreira, Paulo Sérgio FiúzaA new species of Tricorythodes Ulmer (Ephemeroptera: Leptohyphidae) is described based on nymphs from the Northern Region of Brazil. Tricorythodes rondoniensis sp. n. can be distinguished from other species in the genus by the following characters: wide femora, nearly circular, with the margins covered with very long setae; tarsal claws with 5-6 marginal denticles; terga III-VII with an acute median tubercle; o...
