. The true identity of the “Chauve-Souris Onzieme ou Chauve-Souris Cannelle” of Azara (1801) and the “LXXXII Murcielago Acanelado” of Azara (1802) has never been clarified. Though it has historically been associated with the Red Myotis, Myotis ruber (É. Geoffroy St.-Hilaire, 1806), there are clear inconsistencies with that species. Unusual features of the description such as the position of the attachment of the wing membrane to the limbs confirm that the species described by Azara belongs to the Myotis simus Thomas, 1901 group. Two members of that group occur in Paraguay, from where Azara described his specimen: Myotis cf. simus and the recently described Myotis midastacus Moratelli & Wilson, 2014. Measurements and collection locality slightly favour its identity as the former, but it is not possible to conclusively state which of these species Azara had in his possession.

. The giant river prawn, Macrobrachium rosenbergii (de Man, 1879), is a species of great commercial importance. It is farmed under different conditions that translate to a great range of light environments, which impact their behavior and productivity. We present the first study employing both visual modeling and behavioral data to evaluate the ontogenetic changes in color preferences of juveniles and adults of M. rosenbergii . We offered ten shelters of different colors to juveniles and adults and registered their preferences. Our results show that shelter preference changed with ontogeny: juveniles chose shelters based on chromaticity (preference for blue), while adults based their decisions on brightness (preference for dark grey). This preference adults show for dark colors is probably associated with light avoidance behavior. We recommend providing blue shelters for juveniles and dark shelters for adults.

The sharpshooter genus Cavichiana Mejdalani et al., 2014 included so far only two species of about 6-8 mm in length: C. bromelicola Mejdalani et al., 2014 (type species) and C. alpina Quintas et al., 2020. Both are bromeliad specialists from southeastern and southern Brazil. Here a third species, C. caelivittata sp. nov., is described and illustrated based on males and females from the Serra dos Órgãos massif in state of Rio de Janeiro, southeastern Brazil. The new bromeliad specialist can be readily distinguished from the previously known species by the dorsum with a pair of broad whitish-blue stripes, each one extending from antennal ledge over lateroposterior area of crown, lateral portion of pronotum, basal portion of clavus, and forming an elongate arc on corium up to outer margin of first apical cell; the aedeagus bears a dorsoapical digitiform lobe directed posterad. A key to the three species, based on the coloration and morphology of the aedeagus, is provided. In addition, the distribution of C. bromelicola is discussed; it is suggested that the trade of bromeliads as ornamental plants is causing the spread of this species to various urban and suburban areas of southeastern Brazil.

Brazil is the country with the most diverse tarantula (Theraphosidae) fauna, having 215 described species. Vitalius Lucas, Silva Júnior & Bertani, 1993 is one of the most diverse and common genera in Southern, Southeastern and Central-West regions of Brazil with ten described species. Individuals of Vitalius species are large and widespread in areas of the Brazilian Atlantic Forest. A single species is known to occur in areas of Cerrado vegetation. Herein, two new species are described from areas of restinga, coastal areas typically with low vegetation and sandy soil, in the coast of the states of Rio de Janeiro (Vitalius restinga sp. nov.), Bahia and Sergipe (Vitalius sapiranga sp. nov.). Males and females of these two new species have a much longer than wide sternum. Males have a short apical keel in the male palpal bulb. The two species can be distinguished by embolus width, slender in V. restinga sp. nov. and thicker in V. sapiranga sp. nov. Females can be distinguished by the spermathecae shape, slender in V. restinga sp. nov. and broader in V. sapiranga sp. nov. These are the first known theraphosids endemic to Brazilian Atlantic Coast restingas. Biological data indicate V. sapiranga sp. nov. and maybe V. restinga sp. nov. commonly use bromeliads as retreats. It is herein hypothesized they are sister species occupying similar habitats in Brazilian coast, but separated by ca. 1,000 kilometers.

Pseudochthonius lubuenosp. nov., a new obligatory cave-dwelling pseudoscorpion species is described from Gruna da Altina cave, the fifth species of the genus in the region of Serra do Ramalho karst area, southwestern Bahia, Brazil. This genus occurs in South and Central America, sub-Saharan central Africa, and in the Arabian Peninsula. The new species can be identified by the following combination of characters: eyes or eyespots absent, coxa I with two and coxa II with 4-5 coxal spines, without microdenticles on the fixed pedipalpal finger, rallum with five blades, ratio ist-est/ist-esb = 1.9. With this new description, the genus now includes 15 species from Brazil: P. biseriatus Mahnert, 2001, P. brasiliensis Beier, 1970, P. diamachi Prado & Ferreira, 2023, P. gracilimanus Mahnert, 2001, P. heterodentatus Hoff, 1946, P. homodentatus Chamberlin, 1929, P. koinopoliteia Prado & Ferreira, 2023, P. lubueno sp. nov., P. orthodactylus Muchmore, 1970, P. olegario Schimons ky, 2022, P. pali Prado & Ferreira, 2023, P. ramalho Assis, Schimonsky & Bichuette, 2021, P. ricardoi Mahnert, 2001, P. strinatii Beier, 1969 and P. tuxeni Mahnert, 1979. The new species shows troglomorphic characteristics such as the depigmentation of the carapace and the absence of eyes. In addition, illustrations, diagnoses, an identification key for cave-dwelling species of the genus, and distribution maps for all Brazilian species of Pseudochthonius are provided.

Congeneric species have similarities in phenotypic and ecological traits. The sympatry of congeneric species constitutes an opportunity for studies on coexistence. Two bird species of Mimidae, the native Tropical mockingbird, Mimus gilvus Oberholser, 1919, and the restinga invader Chalk-browed mockingbird, Mimus saturninus (Lichtenstein, 1823), currently occur in sympatry across the sandy-coastal ecosystem (restinga) of Espírito Santo state, Southeastern Brazil. We studied the spatial distribution of Tropical mockingbird and Chalk-browed mockingbird to understand the degree of competition across a preserved and urban gradient. We sampled 1,451 sampling units across a preserved and urban landscape in a coastal area of southeastern Brazil. The best-fitting model for abundance (Punctual Abundance Index) included urbanization index, distance from the coast, and distance from the closest protected area, which explained 63% and 97% of the abundance of Tropical mockingbird and Chalk-browed mockingbird, respectively. The species exhibited a segregated spatial pattern at small scale, indicating that both species are avoiding one another. Chalk-browed mockingbird showed ecological plasticity in modified environments, whereas Tropical mockingbird was more sensitive to urbanization. We suggested that the coexistence of these species is associated with resource partitioning. Monitoring Tropical mockingbird populations may be a proxy for the assessment of habitat quality and restoration success in the highly threatened restinga ecosystem.

Measuring cardiorespiratory variables can be challenging in developing animals, especially when they use bimodal gas exchange to maintain metabolic activity. In tadpoles, gas exchange may occur through the integument and gills when breathing in the water and through the lungs when breathing air, with varying contributions of each respiratory structure during development. The interaction between aquatic and air breathing results in a complex physiological response that may affect the cardiac cycle. Measuring the heart rate (fH) together with aquatic and aerial gas exchange in anurans during their development can be challenging, since it may involve handling small animals and/or a certain degree of invasiveness (i.e., surgery to implant electrodes). Here, we evaluated concomitantly aquatic and aerial gas exchange, lung ventilation, and fH in three stages of development of the bullfrog Lithobates catesbeianus (Shaw, 1802). We built a novel, noninvasive, closed respirometry system capable of measuring fH, aerial and aquatic gas exchange simultaneously in animals of different sizes. Our integrative analysis revealed a decrease in the heart rate and an increase in oxygen consumption during the developmental stages of the bullfrog, but there was no adjustment of heart rate after or during air breathing. Moreover, tadpoles in metamorphosis showed higher oxygen consumption in air than in water, while aquatic breathing was responsible for releasing CO2. Our results are consistent with those found in the literature, yet our study represents the first non-invasive investigation to evaluate bimodal gas exchange and heart rate simultaneously. Moreover, our setup holds potential for further advancements that would allow for controlled water and air composition. This tool could greatly facilitate the investigation of how cardiorespiratory physiology responds to varying environmental conditions.

The Medical Malacology Collection (Fiocruz-CMM) was inaugurated in 1993 and is located at the René Rachou Institute in Fiocruz (Belo Horizonte, MG, Brazil). The collection has about 16,000 limnic mollusks of medical and veterinary importance. Information about each specimen is stored in an electronic Microsoft Excel spreadsheet and is available on the Centro de Referência em Informação Ambiental (CRIA) webpage. A QR Code system was implemented for convenience: it can be printed in reduced format with flexible representation on different surfaces and has a low cost of implantation. A script in PHP language was developed to load the spreadsheet in XLS format using an open-license library, PHP-ExcelReader. A PHP script was created to read and process this spreadsheet line by line and generate individual HTML pages, which were formatted with the Bootstrap tool. Then, the PHP QR code was used to create the images of the QR codes corresponding to each specimen. The QR codes were printed and affixed to the lids of the bottles containing each specimen. Using a device with a camera and internet access, the QR code redirects to the file with the information for each mollusk. The use of QR codes at Fiocruz-CMM facilitates the organization of the collection and allows quick and easy access to information about each specimen.
医学Malacology Collection (Fiocruz- cmm)成立于1993年，位于Fiocruz (Belo Horizonte, MG, Brazil)的ren Rachou研究所。这里收藏了大约16000种具有医学和兽医意义的软体动物。每个标本的信息存储在电子微软Excel电子表格中，并可在Referência em informa o Ambiental (CRIA)网页上查阅。QR码系统的实现是为了方便:它可以以简化的格式打印，在不同的表面上具有灵活的表示，并且植入成本低。利用开放许可库PHP- excelreader，开发了一个PHP脚本，用于加载XLS格式的电子表格。创建了一个PHP脚本来逐行读取和处理这个电子表格，并生成单独的HTML页面，这些页面是用Bootstrap工具格式化的。然后，使用PHP QR码创建每个标本对应的QR码图像。QR码被打印并贴在每个标本的瓶盖上。使用带有摄像头和互联网接入的设备，QR码会重定向到包含每个软体动物信息的文件。在Fiocruz-CMM使用QR码有助于收集的组织，并允许快速方便地访问有关每个标本的信息。

The collection has about 16,000 limnic mollusks of medical and veterinary importance. Information about each specimen is stored in an electronic Microsoft Excel spreadsheet and is available on the Centro de Referência em Informação Ambiental (CRIA) webpage. A QR Code system was implemented for convenience: it can be printed in reduced format with flexible representation on different surfaces and has a low cost of implantation. A script in PHP language was developed to load the spreadsheet in XLS format using an open-license library, PHP-ExcelReader. A PHP script was created to read and process this spreadsheet line by line and generate individual HTML pages, which were formatted with the Bootstrap tool. Then, the PHP QR code was used to create the images of the QR codes corresponding to each specimen. The QR codes were printed and affixed to the lids of the bottles containing each specimen. Using a device with a camera and internet access, the QR code redirects to the file with the information for each mollusk. The use of QR codes at Fiocruz-CMM facilitates the organization of the collection and allows quick and easy access to information about each specimen.","PeriodicalId":49335,"journal":{"name":"Zoologia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135649712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
