Species number: 2 [N. dodsonii (Wiehler) Roalson & Boggan, N. peruviana (Wiehler) Roalson & Boggan].
Species names (incl. publication and synonyms): See Skog, L.E. & J.K. Boggan. 2005: World checklist of Gesneriaceae: http://persoon.si.edu/Gesneriaceae/Checklist.
Type species: Nomopyle dodsonii (Wiehler) Roalson & Boggan
Distribution: Ecuador and Peru.
Ecology: Terrestrial forest plants, seasonally dormant.
Notes: Based on molecular evidence, Nomopyle was established to include two species that were formerly placed in different genera: Nomopyle dodsonii (formerly Gloxinia dodsonii), Ecuador, and N. peruviana (formerly Niphaea peruviana), Peru (Roalson et al. 2005a,b; Boggan 2006). Their fruits are very similar to those of Monopyle (opening by a dorsal slit), which is probably the closest related genus.
