Pterospoda nigrescens is a species of moth of the family Geometridae. It occurs at moderate elevations in arid scrub and open woodland habitat, ranging from south-eastern Arizona and the Edwards Plateau of west-central Texas south to at least Durango, Mexico. It is not known from New Mexico, but should occur there.
The wingspan is about 24 mm.[1] There are at least two annual flights, primarily in April and August in Arizona.[2]
The larvae have been reared on Condalia species, probably Condalia warnockii var. kearneyana.
