Trichoptera is the largest order of exclusively aquatic insects, comprising more than 16,000 described species with cosmopolitan distribution. There are about 800 species recorded from Brazil so far, mostly from the North, Southeast, and South regions. In Northeastern Brazil, the state of Rio Grande do Norte has only one Trichoptera species recorded so far (Oecetis excisa). Here, Chimarra (Chimarra) potiguar n. sp. is described and illustrated. The new species can be easily distinguished from its congeners by the following features: Segment X has its mesal lobe elongate, sub-rectangular; lateral lobes long and rounded apically, dorsal margin with subapical invagination; the apex of each inferior appendage has a pronounced apicodorsal acute projection, and the phallotremal sclerite complex is curved, with small spines dorsally. Chimarra (C.) potiguar is morphologically similar to Chimarra (Chimarra) bidens, but the new species differs from it by the length and shape of the mesal lobe and lateral lobes of segment X, and by general shape of the basal regions of inferior appendages. Five additional caddisfly species are recorded for the first time from Rio Grande do Norte state: three in Hydropsychidae (Leptonema sparsum, Macrostemum hyalinum, and Smicridea (Smicridea) palifera) and two in Polycentropodidae (Cyrnellus fraternus and Cernotina bibrachiata).
Two new species of Periphloea Redtenbacher are described based on female specimens from the Brazilian Amazon Basin, namely: P. amazonica sp. nov. (from North of Manaus, ZF-2 reserve, State of Amazonas, Brazil) and P. paraensis sp. nov. (from Eldorado dos Carajás, State of Pará, Brazil). The new species are compared to the other three species (all known from females) and a map of geographical records of the genus is provided, as well as an identification key to females of Periphloea.

Mister Hull, s/n – Campus do Pici, bloco 807, e-mail: patrinebarretof@hotmail.com 1 RESUMO A atividade de irrigação de pequenas hortas, por muito tempo foi de forma simples e manual, entretanto em tempo contemporâneo existem meios de otimizar o processo de irrigação de modo que reduza o consumo de água, supra as necessidades das culturas e otimize o tempo do trabalhador. Este trabalho teve como objetivo desenvolver um sistema de irrigação inteligente para pequenas hortas. A automação foi montada e verificada no sistema de irrigação da horta didática da Universidade Federal do Ceará em um canteiro de 10 m2, onde foram cultivadas espécies olerícolas. Os dados referentes a umidade do solo foram obtidos por um Arduino através de sensores de umidade resistivos, utilizados no sistema de irrigação, cujo objetivo foi manter a umidade do canteiro. Através do monitoramento constante o sistema foi capaz de armazenar informações de umidade e acionamento da irrigação. Assim, comprovou-se a eficácia, a viabilidade e a aplicabilidade do sistema de controle, pois esse foi capaz de monitorar as variações de umidade do solo, acionando e desacionando a válvula no momento ideal além de armazenar a data, hora e umidade de quando a irrigação foi iniciada e concluída. Palavras-chave: Automação, irrigação de precisão, transferência de tecnologia. LINO, D. R.; LIMA NETO, B. P.; QUEIROZ, L. L.; FEITOSA, P. B.; RODRIGUES, A. A.; TEIXEIRA, A. S.AUTOMATED IRRIGATION WITH ARDUINO DEVELOPMENT PLATFORM IN THE DIDACTIC HORTA OF THE FEDERAL UNIVERSITY OF CEARÁ 2 ABSTRACT The irrigation in small vegetable gardens, for a long time, was made in a simple and manual way, however, nowadays, there are ways to optimize the irrigation process in a way that reduces the water consumption, fulfill the crop needs and better use the time of the worker. This work aims at an intelligent irrigation system for small vegetable gardens. The automation was implemented and verified in the irrigation system of the didactic vegetable garden of the Federal University of Ceará, in a 10 m2 plot, where vegetable species were cultivated. The data concerning soil moisture were gathered using an Arduino platform through resistive humidity sensors, used in the irrigation system, whose objective was to maintain the garden humidity. By constantly monitoring the system was capable of storing moisture data and activating the irrigation system. Thus, the effectiveness, viability and application of the control system was confirmed, since it was able to monitor the soil moisture variations, activating and deactivating a valve when convenient, and also being capable of storing the date, time and humidity of the moment when the irrigation process was started and completed. Keywords: Automation, precision irrigation, technology transfer.
This paper provided a list of all new Brazilian Hexapoda species described in 2020. Furthermore, based on the information extracted by this list, we tackled additional questions regarding the taxa, the specialists involved in the species descriptions as well as the journals in which those papers have been published. We recorded a total of 680 new Brazilian species of Hexapoda described in 2020, classified in 245 genera, 112 families and 18 orders. These 680 species were published in a total of 2019 articles comprising 423 different authors residing in 27 countries. Only 30% of these authors are women, which demonstrates an inequality regarding sexes. In relation to the number of authors by species, the majority of the new species had two authors and the maximum of authors by species was five. We also found inequalities in the production of described species regarding the regions of Brazil, with Southeast and South leading. The top 10 institutions regarding productions of new species have four in the Southeast, two at South and with one at North Region being the outlier of this pattern. Out of the total 219 published articles, Zootaxa dominated with 322 described species in 95 articles. The average impact factor was of 1.4 with only seven articles being published in Impact Factors above 3, indicating a hardship on publishing taxonomic articles in high-impact journals. The highlight of this paper is that it is unprecedent, as no annual record of Hexapoda species described was ever made in previous years to Brazil.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
