Remarks — Charletonia salazari sp. nov. belongs to the group of species with four setae between coxae II-III. This group includes species described from Europe, Africa, Asia, Australia and America. The genus Charletonia is barely known from the New World and there are 7 species reported, one from Central America, two from South America and 4 from North America ( Southcott, 1991; Haitlinger, 2000; Haitlinger, 2004; Treat and Flechtmann, 1979). All of them belong to the group with four setae between coxae II-III. The new species belongs to the species group with four setae between coxae II-III, two hypostomalae, solenidion placed distally on Ge I, fn Ge 12,12,12 and Ti III 200 – 255 µm. In this group the following species are included, C. enhoffi Southcott, 1991 , C. froggatti Oudemans, 1910 , C. feideri Southcott, 1966 , C. rageaui Southcott 1966 , C. paolii Southcott, 1966 , C. aerolata (Tragardh 1908) , C. banksi Southcott, 1966 , C. grandpopensis Hailinger, 2007 and C. hunanensis Zheng, 1996 ( Southcott, 1966; Southcott, 1991; Zheng, 1996; Haitlinger, 2007).
