Notes, 4: 53–56, discussed the range of Caecilia mertensi in Mato Grosso, Brazil. Maciel and Hoogmoed, 2011, Zootaxa, 2984: 11–14, provided a detailed account of nominal Caecilia marcusi and a spot map, and noted no substantial diagnostic differences between this taxon and Caecilia mertensi, but having not examined the holotype of the latter, refrained from placing Caecilia marcusi in the synonymy of Caecilia mertensi
