Holotype. — From columnar gall on B. salicina, Pecos R., Loving, Eddy Co., New Mexico

Hosts: This species is reported from B. halimifolia, B. heterophylla, B. neglecta, B. pteronioides, B. salicina, and B. sarothroides. The record on B. heterophylla is based only on similarity of the galls, but the other host records are based on adults and/or pupae. A generation of R. sulcata was reared from B. halimifolia and B. sarothroides in a greenhouse from a generation that came from field-collected galls on B. salicina.
