A new species of Platydoras is described from the rio Xingu Basin, Brazil (2018) and the genus name has now been reclassified as Centrochir. Description: Centrochir birindellii is distinguished from congeners by having gas bladder simple (vs. with posterior secondary chamber) and dorsal and caudal fins uniformly dusky (vs. with distinct marks composed of dark broad band or blotch on central portion of dorsal fin and pair of dark broad stripes on caudal fin, one central to each lobe). Centrochir birindellii shares a simple gas bladder with the sister taxon to Platydoras, Centrochir crocodili, a monotypic genus endemic to the Magdalena Basin. With respect to the caudal skeleton, the parhypural is incompletely fused to hypurals 1+2 in C. birindellii, a condition that is intermediate between those of Centrochir (parhypural typically separated from hypurals 1+2 by distinct suture) and Platydoras (parhypural typically fully fused to hypurals 1+2). Habitat: Centrochir birindellii is commonly found in rocky clearwater rapids and apparently endemic to the middle and upper portions of the Xingu draining the Brazilian Shield. Aquarium Care: This is a fairly easy catfish to keep as long as you can provide it with shelter such as pipes or cave work. It will even jam itself into the pipe with its pectoral spines and will be unremovable. Would need moving water and large stones to hide, replicating its natural habitat. Diet: Easy to feed on frozen food such as bloodworm, tablet and pellet foods. In youngsters it is better to feed at night after lights out, the older they get they will get bolder and come out at feeding time. Etymology: The specific name birindellii: In honour of colleague and friend José Luís O. Birindelli (b. 1979), Universidade de São Paulo, “for enriching our knowledge of doradid catfishes and inspiring the next generation of Neotropical ichthyologists with his enthusiasm and integrity”. Remarks: Can still be found on some online searches as Platydoras birindellii. |

IUCN Red List |
Centrochir birindellii is endemic to the Xingu River basin where it is common in the main channel and in the Iriri River. Extent of occurrence (EOO) is estimated to be 72,984 km2. Continuing decline in habitat quality throughout much of the upper Xingu River Basin is inferred based on the persistence of and documented impacts associated with deforestation, cattle ranching and expansion of the agricultural frontier, mining, and hydroelectric damming infrastructure. However, this species remains abundant in the main channel of the Xingu River and there is currently no evidence of major, range-wide population declines. Therefore, C. birindellii is assessed as Least Concern. (IUCN 2021). |
