(R-249A); Paratypes, 5 larvae, same location, collector and host as holotype (R-249E, F, J, K, L). Holotype and one paratype are deposited in the Museum of Universidad de Costa Rica, two paratypes are deposited in "Museo Nacional de Ciencias Naturales de Madrid " (MNCN- CSIC) in Spain; two paratypes are deposited in the author’s collection.
Description based on holotype — Color in life red. Idisoma ovoid, 560 µm long and 420 µm wide, total length of the animal from the tip of the chelicerae to posterior pole of idiosoma 682 µm.
Dorsum — Bears 52 idiosomalae, apically pointed, lightly barbed and arranged in transverse rows across idiosoma (Figure 2). One eye on each side of the idiosoma, cornea circular, 20 µm across. Dorsal scutum wider than long, with a concave anterior border, convex posterior border and antero- and posterolateral angles rounded. Three pairs of scutalae (AL> ML = PL) and two pairs of sensillae with fine setules in only distal half. Anterior pair of sensillae (AM) shorter than the posterior ones (S).
Venter — Idisoma with a pair of setae between coxae I, with long ciliations as figured; between coxae II a pair of pointed ciliate setae; in the area between coxae II and III four setae, tapering, pointed and ciliate (Figure 2).

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). It is possible to distinguish all these species from C. salazari sp. nov. because of its unique tibia setae formula (fn Ti). Also, they differ from the new species in the following characters.
