| Abstract Among Neotropical freshwater ecoregions, the Mid-Northeastern Caatinga (MNCE) is a fish knowledge gap. Its temporary drainages are receptors of the São Francisco interbasin water transfer project (SFR-IWT) in the Brazilian semiarid. We provide a comprehensive baseline of fish richness of the five SFR-IWT basins. Species richness, shared, endemic, threatened and non-native species were obtained using sampling, ichthyologic collections, literature and online repositories (306 localities). In total 121, species were recorded, 111 of them native, and 16 (14.41%) listed for all basins. Higher richness of native species (78, 70.27%) was recorded in the São Francisco lower-middle stretch (SFRE), including 23 endemic, 61 (54.95%) in MNCE basins (13... |

| One of the most gorgeous colored and endangered Hyphessobryconspecies, H. flammeus Myers, is redescribed. Diagnostic characters of the species are two vertically elongated humeral spots, no caudal peduncle blotch, 5-8 maxillary teeth, caudal fin hyaline, and longitudinal dark stripe of the body absent. Sexual dimorphism is present, with males being more colored than females and having bony hooks in the anal and pelvic fins, which are dark in their terminal portions. Comments about its occurrence in the upper rio Tietê drainage (upper rio Paraná basin), its conservation status, and the phylogenetic position into Characidae context are also presented. |

| Hyphessobrycon uaiso is described from the upper rio Paraná basin, rio Grande drainage, Minas Gerais State. The new species differs from its congeners by the short anal fin with 12-17 branched rays, and dorsal fin with ii,7-8 rays. Besides, it can be distinguished by the presence of i,5-6 pelvic fin rays, and by the coloration of the eyes (in life), slightly blue on the lower half and blackish on the upper half. New records of Hyphessobryconare recognized for the upper rio Paraná basin: H. eilyos Lima & Moreira, H. guarani Mahnert & Géry, and H. herbertaxelrodi Géry. The knowledge status about the ichthyofauna from the upper rio Paraná basin and comments about the type material of some species of Hyphessobrycon are briefly discussed. |

| ABSTRACT Hyphessobrycon itaparicensis was originally described from a small stream in the Itaparica coastal island, Bahia State, Brazil, and has been sampled in several coastal rivers draining Bahia and Sergipe States. Broad examination of type material and recently collected specimens resulted in the redescription provided herein. The presence of one humeral blotch, absence of pseudotympanum, and conservation aspects of H. itaparicensis are briefly discussed. Data obtained from the original description, paratypes and topotypes of H. sergipanus showed broad overlap with H. itaparicensis and absence of morphological diagnostic features supporting the recognition of H. sergipanus as a valid species. Thus, H. sergipanus is considered as junior synonym of H.... |
