Introduction
I currently develop a post doc project on Phylogeography and Integrative Taxonomy of characids in the Universidade Federal da Bahia (UFBA), and contribute to the research program in the Museum of Zoology, University of São Paulo (MZUSP) working on several taxonomic groups.
The main areas of research are Zoology, Systematics (Taxonomy) , Anatomy, and Genetics.
The PhD and Master projects were with Cichlidae, so my main publications are about those cichlids until now.
Recently, I have been involved in projects with Siluriformes, Characiformes (South American Characiformes Inventory - SACI) and Gymnotiformes (Diversity and Evolution of Gymnotiformes).

Crenicichla dandara, new species, is endemic to the rio Xingu above the Belo Monte narrows, and its major left bank tributary the rio Iriri. The new species is distinguished from all congeners by the following combination of characters: body uniformly black (live fishes) or dark brown (preserved specimens) in adults and 74-86 scales in the E1 row....
Crenicichla ploegi, new species, is described based on material from the Rio Juruena (Rio Papagaio, Rio do Sangue, Rio Arinos, and Rio Juruena itself) and from tributaries of the upper Rio Paraguai (upper Rio Jauru, upper Rio Cabaçal and upper Rio Sepotuba) in Mato Grosso, Brazil. Crenicichla ploegi is the twenty-third species of the C. saxatilis g...
In order to change that situation, a new method of sample management has been designed and implemented since October, 2016. The basic principles of this system are: the absolute correlation sample-voucher (individuals as operational units); the partial independence from the “main collection” (lots as operational units); and the optimal cost- benefi...
Over 122 thousand lots are catalogued in the fish collection of the Museum of Zoology of the University of São Paulo (MZUSP), the largest fish collection in Latin America. Traditionally devoted to biodiversity and systematic studies based mainly on morphology, the physical and informational organization of the collection was optimized according to...
Anchoviella hernanni sp. nov. is described from the upper Amazon River basin, in tributaries of the Marañon, Ucayali and Madre de Dios river drainages that drain the Peruvian Andes. The new taxon can be distinguished from all congeners except Anchoviella jamesi, Anchoviella manamensis and Anchoviella perezi, by having 12–15 gill rakers in the lower...
Teleocichla preta nov. sp. inhabits the rapids along the Rio Xingu and lower portion of the Rio Iriri. It is the largest species in the genus, reaching 121·3 mm standard length (LS ) while others do not reach more than 87·8 mm LS . Teleocichla preta is distinguished from all other species of Teleocichla by the unique blackish (in live specimens) or...
Apistogramma eleutheria and Apistogramma flavipedunculata are described from the upper portion of two adjacent tributaries of the rio Curuá on the Serra do Cachimbo. Apistogramma eleutheria, new species, is isolated from the lower portion of rio Treze de Maio (a tributary of the middle rio Curuá), by a waterfall with same name. It is similar to sev...
A cichlid species first collected by Alfred Russell Wallace in the upper Rio Negro in 1852, lost during the transport to England but documented in drawings, is described as Crenicichla monicae on the basis of three specimens collected by the Swedish Amazonas Expedition 1923-1925. Crenicichla monicae is most similar to C. johanna, C. rosemariae, and...
Crenicichla semifasciata was described from the rio Paraguai in “Caiçara” (in front of Cáceres, Mato Grosso, Brazil) and has been reported in the rio Paraguai and lower portion of the rio Paraná downstream of the Itaipu hydroelectric dam, but considered absent in the upper rio Paraná and in the rio Uruguai basin. In this paper, we document the firs...
Apistogramma kullanderi, new species, is described from the upper rio Curuá (Iriri-Xingu drainage) on Serra do Cachimbo, Pará, Brazil, and diagnosed by its maximum size of 79.7 mm SL (vs. 65.3 mm SL among wild-caught congeners); mature females having the unique combination of intense dark pigmentation continuous along base of dorsal fin and on vent...
Teleocichla wajapi, a new species of cichlid from the rio Jari, Brazil, with comments on T. centrarchus Kullander, 1988 (Teleostei: Cichlidae) Abstract Teleocichla wajapi, new species, is described from the rio Jari basin, northern Brazil. The new species differs from its congeners by possessing four anal-fin spines, 56–62 scales in E1 series, smal...
Crenicichla chicha, new species, occurs in clear, fast-running waters with rocky substrates in the rio Papagaio and tributaries. It is distinguished from all other Crenicichla species by the combination of two character states: infraorbitals 3 and 4 co-ossified (vs. separated) and 66-75 scales in the row immediately above to that containing the low...

We hope to propose hypothesis about the biogeography of the southeastern brazilian cichlids and of course a study of the relationships of the species of the same genera too.
This five years thematic project (generously funded by FAPESP and Smithsonian Institution) between the Museu de Zoologia da Universidade de São Paulo (MZUSP) and National Museum of Natural History (NMNH) in alliance with key institutions in Brazil, Europe and USA, will integrate data from morphology, molecules, patterns of geographic distribution and electric organ discharges into a multidisciplinary approach to study biodiversity. Based on the taxonomic (species inventory) and phylogenetic (relationships at various hierarchical levels) components of the proposal, associated with comparative phylogenetic methods, the project will provide study cases in macroevolutionary and microevolutionary scenarios to answer several questions related to patterns and processes of aquatic vertebrate diversity at continental scale. In addition to publishing numerous scientific papers, this effort will serve as a training ground for a new generation of ichthyologists at various academic levels at MZUSP and NMNH. Implementation of this proposal will involve the scientific communities of MZUSP, NMNH, and partners institutions, by conducting workshops and special courses in the graduate program of MZUSP. Educational outreach, among other activities, will be conducted through a permanent exhibit at the National Zoological Park, Youth Access Program, the Sidedoor Podcast, the Q?rius program at the NMNH, and the MZUSP education department.
