- Herein, two species described in Marphysa are transferred to the recently proposed genus Treadwellphysa. After a morphological analysis of the type and additional material, it was found that both species belong to Treadwellphysa, based on the shape of the ventral cirrus with a swollen base as a transverse welt and the shape of maxillae I and II of the maxillary apparatus. Also, two new species, T. rizzoae sp. nov. and T. villalobosi sp. nov., are formally described, with materials studied from Brazil and Costa Rica, respectively. A key to all species of Treadwellphysa is also given. urn:lsid:zoobank.org:pub:693D9279-682F-44E1-B1D5-15A9A5029FB6
