Synaptolaemus latofasciatus, a new combination for Leporinus latofasciatus Steindachner, 1910 and its junior synonym Synaptolaemus cingulatus Myers and Fernandez-Yepez, 1950 (Characiformes: Anostomidae)

Leporinus latofasciatus was described by Steindachner (1910) on the basis of a single specimen collected in the rio Orinoco, Venezuela. Since then, no other specimen of the species was mentioned in the literature, and the species was only listed in catalogues, eventually mentioned and treated as a ""poorly known"" species, or even omitted in checklists of fishes from Venezuela. During a visit to the fish collection at the Naturhistorisches Museum at Vienna (NMW) to examine all the type specimens of Leporinus, we were able to study the holotype of Leporinus latofasciatus and recognize that the specimen corresponds to the species described by Myers and Fernandez-Yepez (in Myers, 1950) as Synaptolaemus cingulatus. Thus, the latter is a junior synonym of Leporinus latofasciatus and, based on that, Synaptolaemus latofasciatus (Steindachner, 1910) should be the name applied for this taxon, as a new combination. Herein new data on the holotype of Synaptolaemus latofasciatus are presented and compared with previously data from other authors. In addition, illustrations of live specimens are presented as well as new distribution records for the species.

Taxonomic and distributional notes on Telebasis Selys, 1865, with a redescription of T. pallida Machado, 2010, and an evaluation of the T. racenisi Bick & Bick, 1995 "complex" of species (Odonata, Coenagrionidae)

A full checklist of the species of Telebasis Selys, 1865, housed in the Brazilian collections Colecao Entomologica Prof. Jose Alfredo Pinheiro Dutra, Departamento de Zoologia, Instituto de Biologia, Universidade Federal do Rio do Janeiro (DZRJ), and Museu de Zoologia, Universidade de Sao Paulo (MZSP) is presented. A total of 325 specimens representing 19 species were studied. Ten new records for Brazilian States were found for T. carmesina Calvert, 1909 (Rio de Janeiro and Rio Grande do Sul), T. corallina (Selys, 1876) (Pernambuco), T. demarara (Williamson, 1917) (Maranhao), T. filiola (Perty, 1834) (Paraiba and Santa Catarina), T. gigantea Daigle, 2002 (Sao Paulo), T. inalata (Calvert, 1961) (Mato Grosso do Sul), T. pallida Machado, 2010 (Goias) and T. obsoleta (Selys, 1876) (Mato Grosso do Sul), as well as a new record of T. carminita Calvert, 1909 for Suriname. Telebasis pallida Machado, 2010 is redescribed and diagnosed based on 14 males collected near the type locality, and its genital ligula is described and illustrated for the first time. Furthermore, the status of the three species of the Telebasis racenisi Bick & Bick, 1995 complex is evaluated. Of these, Telebasis pareci Machado, 2010 syn. n. is proposed as junior subjective synonym of Telebasis lenkoi Machado, 2010, and a possible synonymy among the three species is discussed under T. racenisi.
