Species names (incl. publication and synonyms): See Skog, L.E. & J.K. Boggan. 2005: World checklist of Gesneriaceae:

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.
