Medellinia bordoni Soares and Avram syn. nov. is transferred from Holocranaus Roewer (Cranaidae) to Manaosbiidae attr. nov. and considered a junior subjective synonym of Rhopalocranaus bordoni Šilhavý; Stygnicranella Caporiacco syn. nov. and attr. nov. is here transferred from Cranaidae to Manaosbiidae, and considered a junior subjective synonym of Rhopalocranaus Roewer; R. flaviaculeatus Caporiacco is considered a senior subjective synonym of S. pizai Caporiacco syn. nov. In Cosmetidae, Paecilaema sexlineatum Goodnight and Goodnight, is considered a senior subjective synonym of Paecilaema vitatta González-Sponga syn. nov., currently Paecilaema gonzalezi Kury syn. nov. In Cranaidae, Phareicranaus francourbanii Avram is transferred from its current synonymy, P. benedictoi Soares & Avram comb. nov. is revalidated and considered as a nomen inquirendum, and 4 synonymies are proposed in Phareicranaus Roewer: P. capayitaensis González-Sponga syn. nov., P. francourbanii Avram syn. nov., and P. guaricoensis González-Sponga syn. nov. are considered as junior subjective synonyms of P. albilineatus (Roewer); and P. leonensis González-Sponga syn. nov. is considered a junior subjective synonym of P. curvipes (Roewer). The use of distributional data of some Venezuelan harvestmen in biogeographic studies is discussed.
