Recent reexamination of specimens representing five rarely collected genera of Macrochelidae that I described in 1961 and 1962 has provided valuable supplemental information on their morphology and has uncovered errors in some of the original descriptions. I have incorporated previously unrecognized or misinterpreted features into revised generic diagnoses and have supplemented these with new or corrected illustrations as deemed appropriate. Finally, I present a description of the heretofore undescribed male of Lordocheles desaegeri Krantz, 1961, and synonymize the genus Grafia Krantz, 1962 with Trigonholaspis Vitzthum, 1930.
