The aims of this study were to identify and quantify the gastrointestinal ciliates from Brazilian domestic horses, to compare the data obtained with previous studies and to review data on ciliate communities associated with horses around the world. We used eight domestic horses, kept under extensive management. Fecal samples were obtained immediately after defecation of animals and fixed in 18.5% formaldehyde. We identify 24 species of endosymbiotic ciliates, distributed in two subclasses, two orders, five families and 13 genera. The ciliate composition was similar among the animals analyzed. The family Blepharocorythidae presented the higher prevalence and the family Buetschliidae was observed in greater abundance and density. Among the species identified, Cycloposthium dentiferum was observed for the first time in Central and South America and Bundleia elongata, B. inflata, B. piriformis, B. vorax and Cycloposthium psicauda, were observed for the first time in the American continent. In addition, the species Buissonella tapiri, which was originally discovered in fecal contents of the American tapir (Tapirus terrestris) in Brazil was observed for the first time associated to Equus caballus. The review on the ciliate communities associated with horses around the world demonstrated that the equine ciliates are a very diversified group with representatives in two subclasses, Suctoria and Trichostomatia, totaling 78 species distributed in three orders and six families, having been registered in different equine hosts (Equus asinus, Equus caballus and Equus quagga) and geographic locations (USA, China, Russia, Taiwan, Mexico, Cyprus, Turkey, Kyrgyzstan and Brazil).

First Time

The year 2020 marks the five hundredth anniversary of the “discovery” of the Strait of Magellan. The unveiling of this passage between 1519 and 1522 allowed the planet to be circumnavigated for the first time in the history of humanity. All maritime routes could now be connected, and the idea of the Earth, in its geographical, cosmographic, and philosophical dimensions, gained its definitive meaning. This discovery can be considered one of the founding events of the modern world and of the process of globalization that still continues today. This new connectivity awoke an immediate interest in Europe that led to the emergence of a political consciousness of possession, domination, and territorial occupation generalized on a global scale, and the American continent was the starting point for this. This consciousness also inspired a desire for knowledge about this new form of inhabiting the world. Various fields of knowledge were redefined thanks to the new spaces and measurements produced by the discovery of the southern part of the Americas, which was recorded in books on cosmography, natural history, cartography, and manuscripts, circulating mainly between the Americas and Europe. All these processes transformed the Strait of Magellan into a geopolitical space coveted by Europeans during the 16th century. As an interoceanic connector, it was used to imagine commercial routes to the Orient and political projects that could sustain these dynamics. It was also conceived as a space to speculate on the potential wealth in the extreme south of the continent. In addition, on the Spanish side, some agents of the Crown considered it a strategic place for imperial projections and the defense of the Americas.

The genus Proceratium Roger comprises rare ants that are irregularly distributed in tropical and temperate regions of the world. Despite this global distribution, these ants are rarely collected, likely due to their cryptobiotic lifestyle. In the New World, the genus comprises 22 known species distributed from Southern Canada to the South of Brazil, and in some Caribbean islands. The taxonomy of the genus Proceratium is here updated for South America. We describe P. amazonicum sp. nov, from Rondônia state and provide distribution data for P. brasiliense, P. convexipes, and P. silaceum. We also present, for the first time, high-resolution images of the P. colombicum type and P. ecuadoriense, and provide a new record of P. micrommatum from Peru, and comment about its morphological variation and distribution. A key for the workers of the P. micrommatum clade is also provided. The species we describe belongs to P. micrommatum clade and represents the second species recorded from Brazil after 60 years, since only P. brasiliense was known previously in the country.

From the moment you discover that you are going to be a parent, the hopes, dreams, and expectations you have for your­self and your child flood your mind. No matter how your child is to arrive, your heart is full of hope and promise. You begin to let yourself plan your future. Will your child become president, a doctor, a lawyer, work in the family business, or win the Nobel Peace Prize? Will he or she possess a special talent or skill? Your mind wanders and daydreams of all that is to come. The moment they place your beautiful child in your arms, you realize that there is no greater feeling. You are in love. There is no feeling deeper or grander. The unimaginable joy and gratitude for the blessing of your child is overwhelming. We all know those moments where your heart surged out of your body in awe of the blessing you were given. You may have even asked yourself, “How did I get so lucky?” I can relate. The moment they placed my daughter in my arms for the first time, I knew I had a greater purpose. I would not find out how much for another two years. I devoted myself to her; her care, her introduction to the world, and to the very amazing person I knew she would become. I gave everything of myself tirelessly to her. Her every whimper, cry, or gesture was met with a response. I could anticipate her needs and wants before she fully expressed them. I thought I had an undeniable bond with my daughter. I did. I had a bond that needed no words. That was the problem: we did not need words. If you are like me, you noticed at first subtle differences in your child, and then later there were glaring and alarming indications something was not developing correctly. But, no matter your education or your intelligence level, denial can be a powerful thing.

We propose a revision of the spider genus Corythalia C.L. Koch, 1850 (Salticidae: Euophryini) with a revised genus diagnosis based on examination of all species available to us. In this paper we redescribe all previously described species from South America with revised species diagnoses and describe 20 new species from South America (and the nearby islands). For C. latipes, the type species of the genus Corythalia, a neotype is designated. In total, 52 nominal species of the genus are herein treated, 46 species are recognized as valid. The females of C. waleckii Taczanowski, 1871, C. luctuosa Caporiacco, 1954 and C. latipes (C.L. Koch, 1846) are described for the first time. Corythalia sellata Simon, 1901, erroneously considered as nomen nudum in the present version of the World Spider Catalog, is here recognised as a valid species. Corythalia fulgipedia Crane, 1948 is also considered a valid species and is removed from the synonymy of C. tropica (Mello-Leitão, 1939). One name is considered a nomen dubium (Corythalia variegata Caporiacco, 1954), two are nomina nuda (C. major Simon, 1901; C. dimidiata Simon, 1901). Two species are transferred to other genera: C. argyrochrysos (Mello-Leitão, 1946) to Pachomius Peckham & Peckham, 1896 as Pachomius argyrochrysos (Mello-Leitão, 1946), comb. nov. and C. heliophanina (Taczanowski, 1871) to Neonella Gertsch, 1936, as Neonella heliophanina (Taczanowski, 1871), comb. nov. under incertae sedis. One species is synonymised: C. barbipes (Mello-Leitão, 1939) is a junior synonym of C. cincta (Badcock, 1932), syn. nov. The new Corythalia species are: C. conferta sp. nov. (♂♀, Brazil), C. concinna sp. nov. (♀, Brazil), C. drepane sp. nov. (♂♀, Brazil), C. drepanopsis sp. nov. (♀, Brazil), C. antepagmenti sp. nov. (♂♀, Brazil), C. ricti Bayer, sp. nov. (♂, Guyana), C. protensa sp. nov. (♂, Brazil), C. gasnieri sp. nov. (♂, Brazil), C. verhaaghi sp. nov. (♀, Brazil), C. scutellaris Bayer, sp. nov. (♂♀, Ecuador), C. dakryodes Bayer, sp. nov. (♀, Colombia), C. foelixi Bayer, sp. nov. (♂♀, French Guiana), C. longiducta sp. nov. (♀, Brazil), C. latior sp. nov. (♂, Bolivia), C. trochophora Bayer, sp. nov. (♂, Ecuador), C. lineata Bayer, sp. nov. (♂, Guyana), C. hamulifera Bayer, sp. nov. (♂, Ecuador), C. tribulosa sp. nov. (♂, Colombia), C. flagrans sp. nov. (♂, Brazil) and C. fragilis sp. nov. (♂♀, Brazil). Illustrations are provided for all of the new species and for all (primary) type specimens of the species re-described. Hypotheses of possible relationships among the different species of Corythalia are discussed.

Pem Davidson Buck's book is intended to offer readers a view from under the sink (1). Initially rejecting a career for which her middle-class upbringing had prepared her, Buck moved from Pennsylvania to central Kentucky, where she and her husband became back-to-the-landers, growing and canning food and raising goats and calves, sometimes supplementing the family income by working as part-time day laborers on tobacco farms, as hod-carriers, and as plumbers. But it's not so easy to leave a middle-class liberal upbringing behind, especially down on the farm living below the poverty level. Working as a helper in the small plumbing and heating business she operated with her husband, Buck spent time lying on her back on the floors of the wealthy fixing leaks; from that perspective under the sink she looked up and saw fine furniture and other manifestations of wealth she could not afford. One thing led to another: seeing the world as if for the first time, “it appeared oppressive” (2). People, working people, that is, work extremely hard, and what do they get for their efforts? Boney fingers.

Three genera new for science, i.e. Candelinella S. Y. Kondr. for the Candelariella makarevichiae group, Opeltiella S. Y. Kondr. for the Candelaria fraudans group, as well as Protocandelariella Poelt, D. Liu, J.-S. Hur et S. Y. Kondr. for the Candelariella subdeflexa group are proposed for robust monophyletic branches of the Candelariaceae on the basis of three-gene phylo- geny (i.e. concatenated nrITS, 12S mtSSU and 28S nrLSU sequences). Eight new combinations, i.e. Candelinella makarevichiae (for Candelariella makarevichiae S. Y. Kondr., L. Lokos et J.-S. Hur), Candelinella deppeanae (for Candelariella deppeanae M. Westb.), Opeltiella fraudans (for Candelaria fraudans Poelt et Oberw.), Opeltiella fibrosoides (for Candelaria fibrosoides M. Westb. et Froden), Opeltiella rubrisoli (for Candelariella rubrisoli D. Liu et J.-S. Hur), Opeltiella canadensis (for Candelariella canadensis H. Magn.), Protocandelariella subdeflexa (for Lecanora subdeflexa Nyl.), Protocandelariella blastidiata (for Candelariella blastidiata L. Yakovchenko) are provided.Molecular data provided for Candelinella makarevichiae (including holotype and iso- type), as well as additional specimens of Candelaria asiatica from South Korea for the first time. The latter species (Candelaria asiatica) from China, as well as’Candelaria’ murrayi from Argentina, South America are recorded for the first time. Voucher of Candelariella vitellina from Antarctica is also identified based on molecular phylogeny. It is for the first time shown that ’Candelaria’murrayi is positioned in the outermost position to Candelaria s. str. branch of the phylogenetic tree of the Candelariaceae, and may belong to another genus. Status of the ’Candelariella’medians group, the’Candelariella’ placodizans group, as well as single species ’Candelariella’reflexa and’Candelaria’ pacifica, forming separate branches outside the Candelariella s. str. and Candelaria s. str. clades, will be clarified when additional molecular data will be accumulated. Candelariella subsquamulosa D. Liu et Hur, recently described from South Korea (Liu et al. 2019), proved to be a new synonym of Candelinella makarevichiae.

The land snails of the family Amphibulimidae occurring within northwestern South America are critically examined and notes on their distribution are given. The total number of taxa discussed is 61 (7 Dryptus, 54 Plekocheilus); of these, four Colombian Dryptus and 32 Plekocheilus species are included. The following new species are described: Plekocheilus (P.) bigener, P. (P.) incognitus, Plekocheilus (Eurytus) camaritagua, P. (E.) labiosus, and P. (E.) paraguas. The following nominal taxa are now synonymized: Plekocheilus (P.) speciosus (Pfeiffer, 1854) = P. (P.) plectostylus (Pfeiffer, 1848); Plekocheilus (Eurytus) couturesi Ancey, 1900 = P. (P.) glandiformis (Lea, 1838); Plekocheilus (Aeropictus) latilabris (Pfeiffer, 1855) = P. (A.) succineoides (Petit de la Saussaye, 1840); Plekocheilus (Eurytus) virgatus (Pilsbry, 1935) = P. (E.) mabillei (Crosse, 1867) = P. (E.) pulicarius (Reeve, 1848). Also, Simpulopsis fulguratus Miller, 1878 is now considered a junior subjective synonym of Simpulopsis (Eudioptus) citrinovitrea (Moricand, 1836). For the following species, precise localities are given for the first time: Dryptus stuebeli (Martens, 1885), Plekocheilus (Aeropictus) cathcartiae (Reeve, 1848), P. (E.) cardinalis (Pfeiffer, 1853), P. (Eurytus) episcopalis auriformis (Da Costa, 1904), P. (E.) episcopalis corticosus (Sowerby, 1895), and P. (E.) lynciculus (Deville & Huppé, 1850). Newly recorded for the Colombian malacofauna are the following taxa: Plekocheilus (P.) couturesi (Ancey, 1900), P. (Eurytus) piperitus (Sowerby I, 1837). The following taxa are excluded from the Colombian fauna: Dryptus funckii (Nyst, 1843), Plekocheilus (Aeropictus) veranyi (Pfeiffer, 1848), Plekocheilus (Eurytus) jimenezi (Hidalgo, 1872).
