The Neotropical crab spider genera Tobias Simon, 1895 and Epicadus comprise species with remarkable somatic morphology confounding taxonomic history. results of our recent cladistic analysis corroborate extend preceding assumptions in showing that is a junior synonym Epicadus. In the present paper six recently transferred from to are redescribed. Two new described based on both males females: dimidiaster sp. nov. tigrinus nov.; male granulatus Banks, 1909 for first time. diagnosis genus...
The systematics and taxonomy of Neotropical stephanopines have been extensively studied over the last years (Machado et al. 2015; Silva-Moreira & Machado 2016; 2017, 2018; Prado 2018). According to (2017), genera Epicadus Simon, Epicadinus Simon Onocolus form a clade taxa with characteristic structure male genitalia, consisting long filiform embolus, discoid tegulum canoe-shaped RTA fused at basis an acute curved DTA. However, better diagnostic characters are remarkable somatic features...
The male of Eustala vellardi Mello-Leitão, 1924 and the female E. delasmata Bryant, 1945 are described for first time new distribution records provided. types tridentata (C.L. Koch, 1838), tristis (Blackwall, 1862), essequibensis (Hingston, 1932), uncicurva Franganillo, 1936, nigerrima 1940, albicans (Caporiacco, 1954), apparently lost, those names therefore, considered nomina dubia. andina Chamberlin, 1916, which is based on an immature also a nomen dubium.
Among South American pholcid genera, Mesabolivar Gonzales-Sponga, 1998 is the largest with 94 species (World Spider Catalog 2019). Over last two decades, most of these were described from forest and caves (Huber 2000, 2018a; Huber 2005; Machado et al. 2007a,b,c, 2013). Besides a well-resolved taxonomy, many species' natural history described. Such kind information has been used both to quantify spider diversity in hypothesize how arrived diversified into or around 2018b). Here, we describe...
Suboptimal detection and response to recent outbreaks, including COVID-19 mpox (formerly known as monkeypox), have shown that the world is insufficiently prepared for public health threats. Routine monitoring of performance emergency systems through timeliness metrics has been proposed evaluate improve outbreak preparedness contain threats early. We implemented 7-1-7 measure (target ≤7 days from emergence), notification ≤1 day detection), completion seven early actions notification), we...
A recent phylogenetic analysis has shown that the genus Stephanopis comprises several different lineages of bark-dweller crab spiders. The ones with South American distribution present a close relationship other Neotropical genera like Epicadus, Onocolus, Rejanellus and Epicadinus were recovered in single clade, good support stability. Here, we taxonomic review species attributed to ‘pentacantha clade’, proposing new Kryptochroma Machado gen. nov. accommodate them. New records are provided...
Fulgorídeos são insetos fitófagos sugadores de seiva, conhecidos por suas formas e coloração. Em oposição ao conhecimento evolutivo obtido nos últimos anos, o das descrições espécies mantém-se limitado dos séculos XIX XX, especialmente em grupos neotropicais. Tal limitação fica evidente Zeunasa Distant, 1906, gênero que compreende 13 neotropicais, quatro ocorrentes no Brasil: Z. confusa Nast, 1951 – germari (Gerstaecker, 1860) gerstaeckeri (Jacobi, 1904) turca (Fabricius, 1775). é aqui...
AbstractEnvironmental conditions (i.e., climatic variation) can strongly influence the cost and benefits of reproductive traits. Yet there is still no consensus on whether changing environmental strengthen or relax sexual selection. Evidence from literature suggests that highly variable environments limit mate choice investment in traits, hence relaxing selection pressures. Here, we tested this hypothesis using nuptial gift-giving spider
A composição e a variação sazonal da fauna de Pentatomoidea (Hemiptera) foi avaliada entre setembro 2005 agosto 2006 em três fragmentos Mata Atlântica na região sul Santa Catarina (Brasil): Parque Ecológico José Milanese (Criciúma, 28º41'23''S, 49º25'55''W), Maracajá (Maracajá, 28º52'51''S, 49º27'59''W) Balneário Morro dos Conventos (Araranguá, 28º56'05''S, 49º21'47''W). Foram realizadas coletas mensais ao longo trilhas nas áreas, utilizando guarda-chuva entomológico rede varredura para...
The males of Tobias caudatus Mello-Leitão, 1929 and pustulosus Simon, are described for the first time, females redescribed both sexes illustrated. New distribution records presented species. monstruosus is considered a junior synonym T. pustulosus. types albovittatus Caporiacco, 1954, gradiens lost, albicans corticatus 1917 known only from poorly preserved specimens, thus they all nomina dubia.
The present paper presents a cladistic analysis of the spider genus Tobias Simon, 1895. analyses were based on matrix with 29 terminal taxa scored for 86 morphological characters, dataset tested under two methodologies character weighting (i.e. equal and implied weighting). Both supported paraphyletic relationship Epicadus 1895, former considered junior synonym latter (new synonymy). Onocolus, Epicadinus form clade by synapomorphies, corroborating previous taxonomic assumptions regarding...
This study tests the monophyly of ant‐mimicking Thomisidae (Aphantochilinae and Strophiinae sensu Simon), redefines composition these taxa, proposes tribes discusses aspects their myrmecomorphy biogeography. The analysis is based on a matrix composed 113 morphological characters 37 terminal taxa (11 Aphantochilinae, 16 10 belonging to out‐group). 12 most parsimonious trees with 232 steps, obtained equally weighted characters, support Aphantochilinae Simon. emerges as paraphyletic group...
We newly diagnose, illustrate, and clarify the distribution ranges of six most common broadly distributed species Tetragnatha Latreille, 1804 found in Neotropical region. Twenty new junior synonyms from around world are included, nine for T. bogotensis Keyserling, 1865, four mandibulata Walckenaer, 1841, three keyserlingi Simon, 1890, nitens (Audouin, 1826), one elongata 1841. vermiformis Emerton, 1884 is recorded South America. The Argentine major Holmberg, 1876 riparia considered nomina...
The anatomical and physiological alterations of pregnancy interfere with the repercussions approach to trauma.
Here we present a revision of the Australian species Stephanopis. The type S. altifrons is redescribed and aspera, depressa, monticola, elongata scabra are considered its junior synonyms. Males altifrons, angulata, nigra, armata, fissifrons longimana described for first time. We propose neotypes nigra barbipes describe female latter. Nine inquirendae, thomisoides as nomen dubium cheesmanae transferred to Phrynarachne. Seven new described, distribution records provided comments made about...

Apollophanes has a wide distribution, with some species in Asia and most of the recorded from North Central America (World Spider Catalog 2016). New described Galapagos Islands by Baert (2013) have extended genus range to South America. According Dondale Redner (1975) (1978), moderately low prosoma, usually yellow orange-brown color black or brown spots on lateral margins. The posterior eyes distances are equally spaced legs long, slender speckled dark spots, leg I being longer than IV...
Petrichus athleticus Mello-Leitão, 1944 was described from Punta Piedras, Argentina, based on male and female specimens. The species originally wrongly assigned to Simon, 1886 because it has the cephalic region more elevated than carapace region. However, examination of holotype revealed presence lateral eye tubercles, legs I II longer stouter III IV. These characteristics are considered synapomorphic for Thomisidae. Furthermore, an epigynal hood (type "hood pocket"), RTA long with simple...
Huriini Simon, 1901 currently consists of six genera and 17 species, distributed exclusively in South America. In this work, the huriine genus Guriurius Marta, Bustamante, Ruiz Rodrigues, gen. nov. is proposed with two new species herein described: minuano sp. (type species) nancyae The female Atelurius segmentatus described illustrated for first time. Scoturius dipterioides Perger Rubio, 2018 transferred to due morphological similarity copulatory ducts epigyne, Hurius pisac Galiano, 1985...
This paper presents a taxonomic revision of the genus Tullgrenella Mello-Leito, 1941. Four new species are described: aisenbergae Marta, sp. nov. (Brazil) (), T. legalissima Marta & Hagopin (Uruguay) galianoae () and sciosciae Bustamante (). The males corrugata Galiano, 1981 peniaflorensis 1970, female selenita 1970 described for first time. An updated diagnosis is provided based on detailed comparative morphological studies. In addition, we present proposal discussion about groups putative...
