Etymology: Lutjanus: Malay, ikan lutjan, name of a fish; alexandrei: The specific name honors the pioneer Brazilian naturalist Alexandre Rodrigues Ferreira (1756–1815), whose many years of field work in Brazil during the late 18th Century remain underrecognized due to the confiscation of his and others’ collections at Lisb.

Southwestern Atlantic: the Brazilian snapper, L. alexandrei is only recorded from the tropical portion of the southwestern Atlantic continental shelf, and has a narrower latitudinal range than other Western Atlantic species of Lutjanus. It is known from the state of Maranhão (00°52’S) to the southern coast of the state of Bahia (18°0’S), Brazil, in areas under the influence of the west-flowing Equatorial Current (northern Brazil) and the south-flowing Brazil Current (northeastern Brazil). It is apparently absent from oceanic islands. Additional collections may show an even broader distributional range for this species, as was the case with 48 other poorly known reef-fish species in the southwestern Atlantic (Ref. 57982).
大西洋西南部: 巴西的笛鯛, L. alexandrei 只被記錄西南方大西洋的大陸棚的從熱帶部分, 而且超過 Lutjanus 的其他西大西洋種有一個狹窄的緯度範圍. 它是已知來自馬拉尼昂州 (00 ° 52'S) Bahia 的狀態到南部海岸 (18 ° 0' S) 巴西, 在流動西部近赤道的水流 (巴西北部) 的影響力與南方-流動的巴西水流 (巴西東北部) 下面的區域中. 顯然地它是大洋性島嶼沒有出現。 附加的收集可能顯示甚至比較寬的分佈範圍對於這個魚種, 如同是案例具有 48 另外地在西南方的大西洋知道的很少礁-魚的種.(參考文獻 57982)
