Characidium xavante was described from two tributaries of the Culuene River drainage, in the upper Xingu River basin. New samplings recorded the species for streams from the Kaaiapó River drainage (Teles Pires River drainage, upper Tapajós River basin) with additional specimens also recorded in the Xingu River basin, Paranatinga municipality, Mato Grosso State, Brazil. The new records represent an extension of the geographical distribution of the species, that from now on fits in a pattern of distribution known to be shared with other ca. 20 species of fishes. We suggest that Characidium xavante could be classified as Least Concern (LC), according to the International Union for Conservation of Nature Standards and Petitions Committee (IUCN).
查卡里亚属 xavante 鱼是从欣古河上游的库鲁内河系的两条支流中描述的。新的采样记录了卡亚波河水系（塔帕若斯河上游的特莱斯皮雷斯河水系）溪流中的该物种，在巴西马托格罗索州帕拉纳廷加市的欣古河中也记录了更多的标本。新记录代表了该物种地理分布的扩展，现在该物种的分布模式与其他约 20 种鱼类的分布模式相同。我们建议根据国际自然保护联盟标准和请愿书委员会（IUCN），将查卡里亚属 xavante 鱼列为最不关心（LC）类别。
