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. There are at least two annual flights, primarily in April and August in Arizona. The larvae have been reared on Condalia species, probably Condalia warnockii var. kearneyana. References Moths described in 1898 Caberini
