Cartago, N 9 ° 51.25, W 83 ° 50.36, elevation 1390 m; beating Hibiscus bushes; 30 July 2004; 2 slide-mounted individuals. As above, but on chayote ( Sechium edule ); R. Lain coll.; 1 individual on slide. USA . Florida, Indian River Co., Vero Beach; beating grasses along road at intersection of Fourth Street and Rd. 609; September 2001; P. Armbuster, coll.; 1 individual on slide. Broward Co., Ft. Lauderdale, N 26 ° 0 8, W 80 ° 17; beating grasses along road; September 2001, P. Armbuster, coll.; 1 individual on slide. Buena Vista; on lima beans; 8 December 1982; H. Weeks & D. J. Vandel; 1 juvenile, slide mounted. Description : Length to 1.7 mm (smallest individual= 0.8 mm; average=1.2; n= 4). Body yellow, without blue pigment dorsally; ventrally with scattered blue dots concentrated on posterior part of head and abdominal sterna; antennae amber, with narrow apical blue rings on each segment; legs amber with apical rings on femora and tibia. Ant. 1 (Fig. 20) with 3 (2 in smallest individual) macrosetae. Prelabral setae 2. Postlabial columns CG with 5 normal ciliate setae (1 individual 5 + 6 setae). Macrochaetotaxy of Th. 2 –Abd. 2 (Figs. 21– 24) as 6 (5–7), 6, 4 (2–4), 2; Th. 2 macroseta 7 absent and 5 reduced in some individuals, socket of macroseta 8 smaller than others. Abd. 4 with 3 posterior setae. Number of setae in trochanteral organ varies with specimen size from 7 in smallest individual to 14 setae in largest individual. Claw complex normal for the genus, unguis with 1–2 distal unpaired teeth; most distal unpaired tooth always inconspicuous, sometimes apparently absent. Collophore anterior face with 4 macro- and 2 microsetae; lateral setae 11–13; posterior face with 2 + 2 setae (smallest individual with 1 + 1 setae). Proportion of dens:manubrium≈ 1.3 for largest individual and ≈ 1.0 for others; proportion dental vesicle/mucro ≈ 1.0 irrespective of body size. Mucro with basal dorsal denticle. Remarks : The characters separating S . bidentata from S . wolcotti are discussed in the remarks to S. wolcotti . In chaetotaxy, S. bidentata is most similar to S . thibaudi n. sp ., but differs in having only two prelabral setae, in the absence of peg-like smooth setae along head ventral groove, absence of macroseta 2 and presence of macroseta 7 on Th. 2 and the number of setae on the posterior face of the collophore. Salina bidentata apparently differs from S. ventricolor in chaetotaxy of Th. 2 –Abd. 1, but see comments under S. wolcotti . The individual from Buena Vista, Florida, is a small juvenile originally identified by Wray as S. wolcotti (the logical identification since Florida has more faunistic affinities with the Caribbean than with Central America). The specimen is partially folded over and most characters are difficult to see. The only unambiguous character distinguishing wolcotti and bidentata , the chaetotaxy of Th. 3, is clearly visible and this individual has 6 macrosetae arranged as in Figure 23, hence I have identified this specimen as S. bidentata . Hall (1988) reported S. beta from sugarcane in Florida, but the colour description is consistent with S. bidentata , not S. beta . It is likely that the species was identified using the key in Christiansen & Bellinger (1980), and the first couplet in the key separates species using the shape of the mucro. Delamare-Deboutteville (1951 a) reported S. bidentata from Ivory Coast, but the presence of this species in Africa seems doubtful. Two characters illustrated in Delamare-Deboutteville (1951 a: p. 69, Fig. 18) suggest the African species is different from S. bidentata : the very long antennae in the African specimen suggests it may belong in Pseudosalina , unfortunately, the mucro was not illustrated; in the African species Abd. 3 has the paired bothriotricha in a posterior position whereas in S. bidentata (and in all other New World Salina for which this character has been illustrated) the paired bothriotricha are anterior (e.g., Mari Mutt 1987 a, Fig. 28). : Published as part of Soto-Adames, Felipe N., 2010, Review of the New World species of Salina (Collembola: Paronellidae) with bidentate mucro, including a key to all New World members of Salina, pp. 26-40 in Zootaxa 2333 on page 32, DOI: 10.5281/zenodo.193142 : {"references": ["Handschin, E.
