A new species of Cymbiapophysa Gabriel & Sherwood, 2020, C. magna sp. nov. is described from Colombia. Proshapalopus marimbai Perafán & Valencia-Cuéllar, 2018 is transferred to Cymbiapophysa from Proshapalopus Mello-Leitão, 1923, based on male palpal bulb and tibial apophysis morphology, female spermathecal morphology, comparative labial cuspule counts in
both sexes, and biogeography, creating the new combination Cymbiapophysa marimbai comb. nov. Aspects of some structures of the male palpal bulb are also discussed.
