The skeletal muscles of the dorsolateral region head Nematogenyidae and representatives all major clades Trichomycteridae are described illustrated. A hypothesis on phylogenetic relationships among these taxa exclusively based surveyed musculature is presented. single most parsimonious cladogram obtained from analysis 36 myological characters gathered 35 terminal-taxa mostly agrees with previous hypotheses trichomycterid intrarelationships. Copionodontinae Trichogeninae form a monophyletic...
Responding to purported taxonomic anarchy, in an article published the widely read journal Nature, Garnett & Christidis (2017) [hereafter GC] opined on need for “standardized global species lists”, at behest of conservationists, and proposed construction a judicial committee “restrict … freedom action” promote stability. Here we reflect this perspective contest that view GC conflicts with some basic indisputable principles underpinning philosophy science, most notably: it must be free....
Foram amostrados 17 trechos de riachos com 100 m extensão, todos ordem igual ou menor a três, ao longo ambas as margens do canal principal Rio Paranapanema, SP e PR. O ponto médio cada trecho foi georreferenciado via satélite receptor GPS o uso metodologia padronizada coleta dados ambientais peixes (baseada principalmente na pesca elétrica), possibilitou obtenção das seguintes informações em local: 1) composição taxonômica da ictiofauna contribuição, termos número indivíduos biomassa,...
The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed the Code has already been discussed Zootaxa (Dubois & Nemésio 2007; Donegan 2008, 2009; 2009a-b; Dubois Gentile Snell Minelli Cianferoni Bartolozzi 2016; Amorim et al. 2016). This was again raised a letter supported 35 signatories published journal Nature (Pape 2016) on 15 September 2016. On 25 2016,...

We studied a specialised assemblage of sand-dwelling fish species from streamlet in central Amazonia. The five sanddwelling comprised 15.2 % the total number (33 species). Two sand-dwellers are daytime foragers, Characidium cf. pteroides (Crenuchidae) and Stauroglanis gouldingi (Trichomycteridae), whereas three ones night-time Gymnorhamphichthys rondoni (Rhamphichthyidae), "Imparfinis" pristos Mastiglanis asopos (Heptapteridae). With exception C. pteroides, remainder bury sand during their...
Rhamdiopsis krugi, a new troglobitic heptapterid catfish, is described from the caves of Chapada Diamantina, State Bahia, northeastern Brazil. This species, although frequently cited in scientific literature along last seventeen years, remained undescribed largely due to its uncertain phylogenetic affinities. The generic assignment R. krugi was clouded by high number unusual morphological features (some related cave life), for instance: absence eyes and body pigmentation; presence widely...
Abstract The lateral-line system has been traditionally recognized as an important source of phylogenetic information for different groups fishes. Although extensively studied in Siluriformes and Cypriniformes, the Characiformes remained underexplored. In present study, anatomy cephalic canals characiforms is described detail a unifying terminology that considers ontogeny homologies components this offered. Aspects arrangement canals, well number, location size canal tubules pores, resulted...
(Received 14 June 2019; accepted 23 September 2020) We examine notions of taxonomic 'impediment', 'gap', 'inflation' and 'anarchy', all which are increasingly prevalent in discussions the global biodiversity crisis. Following a critical analysis history those notions, we postulate that entire issue behind them resides deep philosophical deficiency general comprehension principles. In particular, there is profound "conceptual turbulence" knowledge flux between taxonomy conservation biology....
Abstract Heptapteridae is composed of 228 valid species allocated in 24 genera, making it the most diverse family within superfamily Pimelodoidea, a clade endemic to Neotropical freshwaters. Heptapterids are widely distributed from southern Mexico Pampas Argentina and occupy variety habitats generally small‐ medium‐sized rivers. To evaluate phylogenetic relationships Heptapteridae, we used matrix with 1,319 ultraconserved elements (UCEs) genome 56 specimens spanning 42 genera 19 related...
Trichomycterus maracaya, a new species of Trichomycteridae, is described from streamlet in the upper rio Paraná, Poços de Caldas, State Minas Gerais, southeastern Brazil. The following putative autapomorphies distinguishes T. maracaya congeneric species: 1) row lateral blotches not forming stripe at any phase during ontogeny; 2) superficial layer pigmentation juveniles and large (presumably adults) specimens consisting solely scattered chromatophores. Furthermore, characterized by...
Rhamdella cainguae, a new species of the family Heptapteridae is described from Arroyo Cuña-Pirú, tributary Río Paraná, in subtropical forest Misiones, northeastern Argentina. The presence large differentiated ovoid area on supraorbital laterosensory canal along frontal-sphenotic boundary, delimited by slender dorsal walls bones, and with no foramen for branch, an autapomorphy R. cainguae.

Epibranchials are among the main dorsal elements of gill basket in jawed vertebrates (Gnathostomata). Among extant fishes, chondrichthyans most resemble putative ancestral condition as all branchial arches possess every serially homologous piece. In osteichthyans, a primitive rod-like epibranchial 5, articulated to ceratobranchial is absent. Instead, 5 many actinopterygians here identified an accessory element attached 4. Differences shape and attachment raised suspicions about their...
We report on the only known case of independent discovery unrooted trees in a historical science outside biological systematics. The method textual criticism (ecdotics, i.e., building text-version genealogies) created by French philologist Henri Quentin (1872–1935) proposes use type branching scheme equivalent to phylogenetics. Because Quentin's has never become prevailing paradigm philology, his insight into not been noticed previous studies comparing philology and In fact, modern is seen...
Is stability too revered in zoological nomenclature?Recently, the ICZN Commissioners (Ceríaco et al. 2023) issued a formal statement signalling their resistance to promoting replacement of specific epithets honouring historical figures who, for example, advocated racist and/or sexist views, or were otherwise associated with unethical behaviour.Before analysing logic position, we feel compelled comment on origin what believe be 'stability fixation' that forms backdrop most papers criticizing...
Abstract Microcambeva barbata, n. gen. et sp., is described from rio São João, Estado do Rio de Janeiro. It proposed as the sister group of Malacoglanis and Sarcoglanis, on basis three characters: pectoral fin longer than head, rays projecting well beyond membrane, a forked caudal fin. Monophyly Sarcoglanidinae confirmed by unique possession long lateral process premaxilla separate anterior ossification palatine. A relationship between Glanapteryginae supported four synapomorphies:...
