We review the taxonomy and ecology of Chloropidae (Diptera) associated with pitcher plants (Sarraceniaceae) in North America. Tricimba wheeleri Mlynarek sp.n. is described from the pitchers of Sarracenia alata Alph.Wood and S. leucophylla Raf. in the southeastern United States (Alabama, Mississippi). Aphanotrigonum darlingtoniae (Jones) associated with Darlingtonia californica Torr. in northern California is redescribed, including the first description of male genitalic characters. A lectotype is designated for A. darlingtoniae. Published records of other species of Tricimba Lioy in pitcher plants in North America are considered accidental or facultative occurrences; published records of Aphanotrigonum Duda as pitcher plant associates in eastern North America are probably errors in identification.
