when carl linnaeus first described this species in 1758, he named it "balanus tintinnabulum". the lectotype was depicted by georg eberhard rumphius in 1705, the type locality being ambon, indonesia. in a monograph on barnacles in 1854, charles darwin described the species as being very variable and assigned it to section a of the genus "balanus", characterised by having the parietes, basis, and radii (different plates in the shell wall) permeated by minute pores. in 1916, henry augustus pilsbry elevated "balanus tintinnabulum" to subspecies rank and in subsequent years a number of varieties were described. later it was placed in the subgenus "megabalanus" and in 1976, newman and ross elevated "megabalanus" to generic rank, giving species rank to each of the 22 subspecies of what had previously been known as "balanus (megabalanus) tintinnabulum".

the diversity of galago species has historically been grossly underestimated. in 1931, only 5 species were recognized, 4 in the genus "galago" and 1 in "euoticus", and only one species that would later be placed in the genus "otolemur". in 1979, the genus "otolemur" was separated from "galago". by 1986, eleven species were recognized with revamped systemic classification including "otolemur crassicaudatus" and "otolemur garnettii". additionally, "o. crassidautus" and "o. monteiri" were recognized as separate species instead of "o. monteiri" as a nested subspecies. by 2001, 23 species were recognized. classification by vocalization has particularly become prevalent and helpful as a tool in understanding of these species. all "otolemur" species exhibit trailing advertising calls.
