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.
Eponymy: Alexandre Rodrigues Ferreira (1756–1815) was an early Brazilian naturalist. [...] (Ref. 128868), visit book page.

بلوغ: Lm ?  range ? - ? cm
Max length : 33.1 cm TL جنس نر / بدون خواص جنسي; (Ref. 100833); بيشينه وزن گزارش شده: 199.90 g (Ref. 122735)
Adult standard length is greater 20 cm (Ref. 57982). 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).
