Etymology: Characidium: Diminutive of Charax, -akos = a fish without identification (Ref. 45335); xavante: Named for its type locality, Córrego Xavante. Xavante refers to the indigenous Brazilian ethnic group, inhabiting the region between the Rio das Mortes and Rio Culuene, Mato Grosso; also the stream at the type locality is named after this ethnic group.
Eponymy: The Xavante are an indigenous ethnic group who live in the region between Rio das Mortes and Rio Culuene, Mato Grosso, Brazil. They are the largest Amerindian tribe in the area where the rivuline species was discovered. (Ref. 128868), visit book page.

ຄີຫຼັງຂອງປາ (ຄີອ່ອນ) (ທັງໝົດ) : 12 - 13; ຄີກົ້ນຂອງປາ: 9 - 10; ສັດທີ່ມີກະດູກສັນຫຼັງ: 32 - 33. Belongs to a group of species, including Characidium nupelia, distinguished uniquely by having high number (12-18) of dark vertical bars on the body, each bar having the width of a scale. Diagnosed by a lower number of scales around the caudal peduncle (10 vs. 12 or more in most Characidium species). Differs from Characidium nupelia by its wider interorbital region (interorbital distance 30.1-38.0 vs. 20.5-28.6% HL) and lower caudal peduncle (caudal peduncle depth 35.4-44.9 vs. 46.2-57.8% HL). Additional conspicuous external characters that are not unique but are helpful in the identification of this species include absence of adipose fin, incomplete lateral line, and presence of a dark blotch on the caudal peduncle (Ref. 75787).
Body shape (shape guide): elongated.
