Oecophoridae Oecophoridae (concealer moths) is a family of small moths in the superfamily Gelechioidea. The phylogeny and systematics of gelechoid moths are still not fully resolved, and the circumscription of the Oecophoridae is strongly affected by this. Also possibly included is the Peruvian species "Auxotricha ochrogypsa", described by Edward Meyrick in 1931 as the sole member of its genus. In the past, the family was circumscribed more widely and
Rockstone poison dart frog Rockstone poison dart frog The Rockstone poison dart frog ("Dendrobates nubeculosus") is a poorly known species of dendrobatid frogs endemic to Guyana. As it is known from only one specimen, very little information is currently available on "D. nubeculosus". It has been suggested to be one of the most poorly known species in the world. "D. nubeculosus" is a small to medium-sized poison dart frog; larger than many of its contemporary "Ranitomeya" species, but smaller than the other members of the genus "Dendrobates". The holotype specimen measures 2.5 centimetres in length, and the species' size range is unknown. It is
