The females of Oxysoma itambezinho Ramírez and Monapia tandil Ramírez are described for thefirst time, and new observations are added to a previous dataset for phylogenetic analysis. Oxysomaitambezinho differs from other Oxysoma species by the presence of unmodified copulatory ducts,not encircling the spermathecae. Monapia tandil resembles some Monapia species by the presenceof a posteriorly directed pouch on the median epigynal field, unlike its sister species, M. vittata. Theresulting phylogenetic trees are the same as previously obtained, but these instances of homoplasydecreased the support for some groups inside Oxysoma and Monapia.
