Taxonomia E Filogenia De Peixes De Riachos Brasileiros
Oecologia Australis 25(2):197–230, 2021 https://doi.org/10.4257/oeco.2021.2502.01 TAXONOMIA E FILOGENIA DE PEIXES DE RIACHOS BRASILEIROS Paulo Andreas Buckup1* 1 Universidade Federal do Rio de Janeiro, Museu Nacional, Quinta da Boa Vista, CEP 20940-040, Rio de Janeiro, RJ, Brasil. E-mail: [email protected] (*autor correspondente). Resumo: A fauna de peixes de riachos brasileiros compreende 36 famílias de peixes teleósteos de água doce. O conhecimento sobre a sistemática e filogenia deste conjunto de espécies ampliou-se consideravelmente nas últimas duas décadas, porém ainda é muito heterogêneo, havendo grupos sobre os quais pouco se conhece, assim como grupos para os quais há chaves de identificação e hipóteses filogenéticas recentes e bem documentadas. O número de famílias de peixes de água doce com presença frequente em riachos brasileiros ampliou-se de 31 para 36. Este crescimento no conhecimento da diversidade dos peixes neotropicais refletiu-se no grande desenvolvimento das hipóteses sobre sua evolução e contribuiu para o entendimento da história filogenética e estruturação das comunidades de peixes de riacho. Palavras-chave: biodiversidade; classificação; filogenia; riachos; sistemática. TAXONOMY AND PHYLOGENY OF FISHES FROM BRAZILIAN SMALL STREAMS: The fish fauna occurring in Brazilian small streams comprises 36 families of teleost freshwater fishes. The systematics and phylogenetic knowledge about this fauna greatly expanded during the last two decades, but is still very heterogeneous. For some taxonomic groups there are taxonomic identification keys and well-documented phylogenetic hypotheses, while other groups are mostly comprised by poorly known species. The increase in the knowledge of Neotropical fish diversity was associated with the significant growth of hypotheses about their evolution and contributed to the understanding of the phylogenetic history of fish comunities and their structure in small streams. -

(Monogenea, Dactylogyridae) from the siluriform catfish Loricaria prolixa Isbrücker & Nijssen, 1978 (Siluriformes, Loricariidae) from the state of São Paulo, Brazil, supported by morphological and molecular data. In add- ition, notes on the circumscription of the genus with a redescription of Demisdospermus anus are presented. Demidospermus spirophallus n. sp. differed from other congeners mainly because of the morphology of the male copulatory organ (MCO), which exhibited 2½ counterclockwise rings, a tubular accessory piece with one bifurcated end and a weakly sclerotized vagina with sinistral open- ing. Demidospermus prolixus n. sp. presents a counterclockwise-coiled MCO with 1½ rings, an ovate base, a non-articulated groove-like accessory piece serving as an MCO guide, two different hook shapes, inconspicuous tegumental annulations, a non-sclerotized vagina with sinistral opening and the absence of eyes or acces- sory eyespots. The present study provides, for the first time, molecular character- ization data using the partial ribosomal gene (28S) of two new species of Demidospermus from Brazil (D. -
