Behavioral Evidence of Chemical Communication by Male Caudal Fin Organs of a Glandulocaudine Fish (Teleostei: Characidae)
1 Ichthyological Exploration of Freshwaters/IEF-1127/pp. 1-11 Published 22 September 2020 LSID: http://zoobank.org/urn:lsid:zoobank.org:pub:483EB8ED-1D49-4584-9030-DE92226A6771 DOI: http://doi.org/10.23788/IEF-1127 Behavioral evidence of chemical communication by male caudal fin organs of a glandulocaudine fish (Teleostei: Characidae) Clayton Kunio Fukakusa* All fishes in the tribe Glandulocaudini have hypertrophied tissue with club cells in the caudal fin (the caudal organ). Because this structure is present only in adult males, it is hypothesized that these cells secrete a reproduction-related pheromone. The hypothesis that the caudal organ releases chemicals that attract females is tested in Mimagoniates inequalis. In a Y-maze and an aquarium, females were attracted to a caudal organ extract and to water that was conditioned with caudal organ-bearing males, respectively, but not to caudal-fin lobe extract or water conditioned with males from which the caudal organs were removed (control stimuli). In tests with male-female pairs, there were no differences in the responses to caudal organ extract and male caudal organ-conditioned water, but the responses to both stimuli differed in relation to the controls. Male-female pairs engaged in fewer courtship events and more agonistic interactions than they did without chemical stimuli and with control stimuli. These results provide evidence for a possible pheromonal system in M. inequalis. The caudal organ is a specialized secretory structure that produces a chemical signal that attracts females and increases the aggressiveness of males.

Phylogenetic Relationships Within the Speciose Family Characidae
Oliveira et al. BMC Evolutionary Biology 2011, 11:275 http://www.biomedcentral.com/1471-2148/11/275 RESEARCH ARTICLE Open Access Phylogenetic relationships within the speciose family Characidae (Teleostei: Ostariophysi: Characiformes) based on multilocus analysis and extensive ingroup sampling Claudio Oliveira1*, Gleisy S Avelino1, Kelly T Abe1, Tatiane C Mariguela1, Ricardo C Benine1, Guillermo Ortí2, Richard P Vari3 and Ricardo M Corrêa e Castro4 Abstract Background: With nearly 1,100 species, the fish family Characidae represents more than half of the species of Characiformes, and is a key component of Neotropical freshwater ecosystems. The composition, phylogeny, and classification of Characidae is currently uncertain, despite significant efforts based on analysis of morphological and molecular data. No consensus about the monophyly of this group or its position within the order Characiformes has been reached, challenged by the fact that many key studies to date have non-overlapping taxonomic representation and focus only on subsets of this diversity. Results: In the present study we propose a new definition of the family Characidae and a hypothesis of relationships for the Characiformes based on phylogenetic analysis of DNA sequences of two mitochondrial and three nuclear genes (4,680 base pairs). The sequences were obtained from 211 samples representing 166 genera distributed among all 18 recognized families in the order Characiformes, all 14 recognized subfamilies in the Characidae, plus 56 of the genera so far considered incertae sedis in the Characidae. The phylogeny obtained is robust, with most lineages significantly supported by posterior probabilities in Bayesian analysis, and high bootstrap values from maximum likelihood and parsimony analyses. -

Ciencias Ecológicas, Facultad de Ciencias, Universidad de Chile, Santiago, Chile. [email protected] RESUMEN La ictiofauna nativa de los sistemas límnicos de Chile se compone de 11 familias, 17 géneros y alrededor de 44 especies, incluyendo dos lampreas. De éstas, 81% son endémicas de la provincia biogeográfica chilena y 40% se encuentran clasificadas en peligro de extinción. Los grupos más representados corresponden a los órdenes Siluriformes (11 especies), Osmeriformes (9 especies) y Atheriniformes (7 especies). También están representados en Chile los ciclóstomos Petromyzontiformes (2 especies), y los teleósteos Characiformes (4 especies), Cyprinodontiformes (6 especies), Perciformes (4 especies) y Mugilifromes (1). Latitudinalmente, la mayor riqueza de especies ocurre en la zona centro-sur de la provincia Chilena, en tanto que los extremos norte y sur son de baja riqueza específica. Dado su origen, porcentaje de endemismo y retención de caracteres primitivos, este conjunto ictiofaunístico es de alto valor biogeográfico y de conservación. Existen sin embargo importantes vacíos de conocimiento sobre su sistemática, distribución y biología. PALABRAS CLAVES: Peces, sistemas dulceacuícolas, Chile.

Además, analizamos los posibles orígenes de esta ictiofauna, postulando que parte de la cuenca del río Valdivia ha funcionado como un sumidero, principalmente su parte alta, con aportes de fuentes tanto costero-Pacífi cas como del Este de Los Andes. Concluimos que el río San Pedro es de particular valor ictiofaunístico por su alta riqueza específi ca, endemismos y características biogeográfi cas. PALABRAS CLAVE: Fauna íctica, Río San Pedro, Endemismos, Conservación, Chile. ABSTRACT Based on three consecutive years of sampling and bibliographic revision, the composition, singularity and conservation status of the San Pedro River ichthyofauna is described. In addition, the potential origin of this Valdivia River ichthyofauna was analyzed and this basin is proposed to have worked like a sink, mainly the higher zone, having been colonized both from Coastal-Pacifi c as from Eastern Andes sources. It is concluded that this river has a particular conservation value due to its high species richness, endemism and biogeographic characteristics. -

From Rio Grande Do Norte State, Northeastern Brazil

Jerep1,2 and Luiz R. Malabarba3 Serrapinnus potiguar, new species, is described from the rio Ceará-Mirim, a coastal drainage in the Rio Grande do Norte State, northeastern Brazil. The new species is distinguished from the other species of the genus by the shape and arrangement of the ventral procurrent caudal-fin rays of the sexually dimorphic males; where the hypertrophied elements present the shape of a series of scimitars arranged radially, forming a semi-circle on the ventral margin of the caudal peduncle. Furthermore, the new species is diagnosed from S. heterodon and S. piaba, sympatric congeners from the northeastern Brazilian drainages, respectively by the presence of incomplete lateral line and teeth bearing at most five cusps. Serrapinnus potiguar, espécie nova, é descrita para o rio Ceará-Mirim, uma drenagem costeira localizada no estado do Rio Grande do Norte, na região Nordeste do Brasil. A espécie nova distingue-se das demais espécies do gênero pela forma e arranjo dos raios procorrentes ventrais da nadadeira caudal nos machos sexualmente dimórficos; onde os elementos hipertrofiados possuem o formato de uma série de cimitarras arranjados radialmente na margem ventral do pedúnculo caudal, formando um semicírculo. Adicionalmente, a nova espécie diferencia-se de S. heterodon e S. piaba, congêneres simpátricos para as drenagens do Nordeste brasileiro, respectivamente pela presença de linha lateral incompleta e dentes com no máximo cinco cúspides. -

Agudelo-Zamora1, Juan G. Ospina-Pabón 1, 2 y Luz F. Jiménez-Segura1 Resumen En este artículo se revisan los ejemplares del río San Juan de Urabá depositados en museos nacionales e internacionales y, con base en esta revisión y otros estudios publicados, se documenta el primer listado de los peces del río San Juan de Urabá. Hasta la fecha, el conocimiento científico de la fauna íctica de esta región sigue siendo muy pobre. El único estudio sobre el río fue publicado en 1992 y sólo se enfocó en la zona costera donde encontraron 40 especies. Basado en nuestra revisión de especímenes de museos, se identificaron 38 especies en la cuenca, 15 de éstos fueron Perciformes y el orden más abundante. Las cuencas aisladas actúan como sistemas individuales que pueden contener biotas únicas, además son de alta importancia en un contexto biogeográfico, porque ellas actúan como sistemas particulares.
