INTRODUCTIO N One of the characid subfamilies currently recognized is the Stetha­ prioninae. This group is usually diagnosed by the presence of a variably­ shaped, forward directed, bony spine articulating on the dorsal-fin origin, and usually a deep, discoidal body. The subfarnily Stethaprioninae was proposed by Eigenmann (1907) to include the genera Stethaprion Cope, 1870, Fowlerina Eigenmann, 1907 (currently synonym of Poptella Eigenmann, 1908), and Brachychalcinus Boulenger, 1892. The Stethaprioninae has been considered a subfamily of the Serrasalmidae (Fowler, 1950) anda tribe of the Tetragonopterinae (Géry, 1964). The group was divided in two tribes by Fowler ( 1958): the Brachy- 4 Comun. Mus. Ciênc. PUCRS, Sér. zool. Porto Alegre/v.2/n9 6/p.3-86/1989 chalcinidi, incluc.ing those species with less than 40 lateral-line se ales (Brachy­ chalcinus and Poptellat and Stethaprionidi, including those species with more than 60 lateral-line scales (Stethaprion ). This study aims to advance an hypothesis of stethaprionin monophyly, to determine the phylogenetic interrelationships within the subfamily, and to providc diagnoses for the genera and species along with the arcas ofende­ mism for each species. METHODS Toe almost 2000 stethaprionin specimens examined in this study be­ long to 19 fish collections, whose acronyms follow Leviton et AI. {1985), cxccpt for Museu de Historia Natural da Universidade Federal de Minas Ge­ rais (MHNI). Toe osteological material was cleared and coun terstained for bone and cartilage according to the method of Dingerkus & Uhler (1977). All drawings werc made with a Zeiss stereomicroscopic camera lucida. Abbreviations in the text are: C&S, cleared and stained specimen; LI and L2, lower and upper confidence limits; SD, standard deviation; and SL, standard length. Toe measurement ..dorsal head length", present in all tables, was taken f rom the upper lip to the end of the supraoccipital process. Other measurements or counts are self-explanatory. ln the list of specimens examined the number of specimens in each lot follows the catalog numbers. Toe geographic dis­ tribution for each taxa is based solely on specimens actually examined and is prcsented in the maps of figures 1, 18, 25, and 29. Ali statistical treat­ ment was performed with the microcomputer program ..Tratamento de Dàdos Biométricos para Taxonomia - DATAX", available from MCP Lab9- ratório de lctiologia. The study of phylogcnctic relationships followed the principies of the Phylogcnetic Systcmatics, first proposed by Hennig (1966), under which uniquely derived characters are considercd the only valid basis to hypothe­ sizc natural groups (see Wiley, 1981 for a review and update of Hennig's principies). Polarity decisions were baseú on comparisons with the outgroups listcd in thc Appendix. The BraQCh-and-Bound option of the PAUP program (Swofford, 1985) was used to check the cladistíc analysis. Comun. Mus. Ciênc. PUCRS, Sér. zool. Porto Alcgre/v.2/n9 6/p.3-86/1989 5 Toe various stethaprionin genera and species shcw a hlgh degree of mor­ phological unifonnity in numerous characters. ln order to reduce repetition in the species accounts, such invariant characters are described in the sub­ f amily and generic diagnosis, and are not repeated in the subsequent species descriptions. PHYLOGENETIC HYPOTHESIS AND CLASSIFICATION OF STETHAPRIONINAE Possible interrelationships among stethaprionins have been discussed by severa! authors (Cope, 1872; Eigenmann, 1907, and 1908; Eigenmann& Myers, 1929; Tortonese, 1942; Fowler, 1958; Géry, 1964, and 1965). These discussions, however, were based solely on the intuitive ideas of those authors, without a rigorous theoretical basis. Toe stethaprionin genera are very uniform osteologicall} (figs. 3 to 6). Toe only reason they are not currently placed in the Tetragonopterinae is their possession of a well developed predorsal spine. Stethaprionins are pro­ bably closely related (that is, are the sister-group) to some group within the Tetragonopterinae, a vast and complex assemblage of largely little specialized characids. This probably para- or polyphyletic assemblage is not defined by the possession of shared derived characters but rather by their absense. Toe sister-group of stethaprionins, however, was not discovered as no synapomor­ phies uniting them to other characid species were found. To attain this objec­ tive an extensive

  • Behavioral Evidence of Chemical Communication by Male Caudal Fin Organs of a Glandulocaudine Fish (Teleostei: Characidae)

    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.

We also included here Maximum-likelihood and Bayesian topologies, which support two main gymnotiform clades: Gymnoti- dae and Sternopygoidei, the latter comprised of Rhamphichthyoidea (RhamphichthyidaeþHypopomidae) and Sinusoidea (Sternopygi- daeþApteronotidae).

Azevedo Setor de Ictiologia, Museu de Ciências Naturais, Fundação Zoobotânica do Rio Grande do Sul, Rua Dr. Salvador França, 1427, 90690-000 Porto Alegre, RS, Brazil. ([email protected]) ABSTRACT. In this study, I investigated the reproductive biology of fish species from the family Characidae of the order Characiformes. I also investigated the relationship between reproductive biology and body weight and interpreted this relationship in a phylogenetic context. The results of the present study contribute to the understanding of the evolution of the reproductive strategies present in the species of this family. Most larger characid species and other characiforms exhibit a reproductive pattern that is generally characterized by a short seasonal reproductive period that lasts one to three months, between September and April. This is accompanied by total spawning, an extremely high fecundity, and, in many species, a reproductive migration. Many species with lower fecundity exhibit some form of parental care. Although reduction in body size may represent an adaptive advantage, it may also require evolutionary responses to new biological problems that arise. In terms of reproduction, smaller species have a tendency to reduce the number of oocytes that they produce. Many small characids have a reproductive pattern similar to that of larger characiforms. On the other hand they may also exhibit a range of modifications that possibly relate to the decrease in body size and the consequent reduction in fecundity.
