NOTES.— Daniel (1986a) provided a description of this rare species (Fig. 3E), which is endemic to Tamaulipas. Phylogenetic relationships among species of Mirandea (Kiel and McDade 2014), suggest that the genus is not monophyletic as currently delimited. With an EOO of 179 km 2 and an AOO of 16 km 2 this species could potentially be assessed as endangered (EN) if threats and their impacts were to be identified (IUCN 2019).
