The dolichopodine genus Paraclius Loew (Diptera: Dolichopodidae) presently includes over 150 described species worldwide and about 60 from the Neotropics (Yang et al. 2006; Capellari & Amorim 2009). Nevertheless, the genus was recovered as a polyphyletic assemblage of different lineages by Brooks (2005), and splitting of Paraclius into new genera will probably be required in the future to accom...
