Última Biological variables of Hypostomus francisci (Siluriformes: Loricariidae) from Itapecerica River, Minas Gerais State, Brazil Anais da ABC (AABC) SALES,CAMILA F.; DOMINGOS,FABRÍCIO FLÁVIO T.; BRIGHENTI,LUDMILA S.; RIBEIRO,ROSY I.M.A.; SANTOS,HÉLIO B.; THOMÉ,RALPH G.. ABSTRACT Herein we determine for the first time the reproduction parameters and population structure of Hypostomus francisci in the Itapecerica River, São Francisco Basin. A total of 250 specimens was captured quarterly between March 2010 and February 2012. Body weight, total length and weight of the gonads were obtained in the laboratory. Gonad samples were submitted to histological and histochemical techniques. Females with spawning capable ovaries were used to determine the fecundity and relative fecundity. Sex ratio with 1:1.01 (female:male) was observed. Males were more numerous than females for individuals smaller than 170 mm, however the number of females was significantly greater for specimens larger than 330 mm. The length-weight relationship...

Avulsos de Zool. (São Paulo) Britski,Heraldo A.; Mendonça,André L.C.. Syntypes of Corydoras meridionalis Rodolpho von Ihering, 1911, once regarded as lost, were recently found in the collection of fishes of the Museu de Zoologia da USP. The syntypes had been identified as C. ehrhardti Steindachner, 1910, currently considered a senior synonym of that species. Examination of the rediscovered syntypes corroborates the proposed synonymy. Data on the syntypes are presented and compared with information in the original descriptions of C. ehrhardti and C. meridionalis; a few discrepancies found are discussed. A lectotype is designated for C. meridionalis and a photograph of the specimen is provided. Tipo: Info:eu-repo/semantics/other Palavras-chave: Taxonomy; Catfish; Neotropical freshwater fish.
