[1] Molecular sequencing data indicates that the closest relatives of M. kalinowski are members of another genus, Nyctinomops.

[3] The eponym for the species name "kalinowskii" was Jan Kalinowski, a Polish zoologist who immigrated to Peru.

[4] Thomas wanted to acknowledge Kalinowski's efforts in collecting the holotype, saying that he was the collector "to whose labours we owe the valuable collection of small Mammals described in the present paper.
