Minyobates steyermarki
''Minyobates steyermarki'' (formerly ''Dendrobates steyermarki'') is a species of frog in the family Dendrobatidae endemic to Cerro Yapacana in southern Venezuela. It is also known by the common names of demonic poison frog, demonic poison-arrow frog, or Yapacana's little red frog.〔 It is monotypic in the genus ''Minyobates''.
Its natural habitat is montane tepui forest where it is common in terrestrial habitats among moss-clad rocks and breeds in bromeliads. Threats to this species include open pit gold mining, collection for the pet trade (and occasionally, for scientific purposes), and possibly wildfires, and the IUCN has assessed it as being "critically endangered".

The underparts are also similar but have rather larger dark blotches.
