G. 196: near pond at Boire, 1 km west of Cocoyer; leaf litter of breadfruit and flower of banana tree; 29 January 1980; 1 slide-mounted juvenile. Costa Rica. Cartago, El Salvador; 14 June 2004; C. Guillén, coll.; 1 slide-mounted.

Description: Length to 1.7 mm (smallest= 1.2 mm; average= 1.4 mm; n= 8). Background colour yellowish green, dorsal head pattern formed by narrow blue band along marginal circumference, wider near eyes and between antennae; mesothorax with a scatter of blue and narrow anterior and lateral stripe along margins; Th. 3 –Abd. 5 with dark blue spots with irregular outer edges and unpigmented centres (i.e., Folsom’s amoeboid spots, Fig. 12View FIGURES 1 – 12. 1 – 4), corresponding to macrosetal insertions; ventral pattern formed by scattered light blue pigment on posterior two thirds of head, extending back in an irregular pattern through out all sterna, with higher density just posterior to metathoracic legs and on depression formed to accommodate furcula; antennae light blue, pigment forming rings distally on Ant. 1–3; femora with anterior blue longitudinal bands, one distal ring on femora, and one basal and one distal ring on tibiotarsi. Ant. 1 ( Fig. 27View FIGURES 25 – 33) with 4 (3–5) dorsal macrosetae. Prelabral setae 4. Postlabial column CG with 9 setae (7–10), of which 3 (2–4) are short and smooth ( Fig. 5View FIGURES 1 – 12. 1 – 4). Macrochaetotaxy of Th. 2 –Abd. 2 as 7 (7–8), 6 (5–9), 4 (3–6), 2 ( Figs. 28–31View FIGURES 25 – 33): Th. 2 with a supplementary macroseta posterior to seta number 3. One individual with 9 paired macrosetae on Abd. 4; 3 individuals with unpaired macrosetae inserted in differing patterns on each individual, but always in general area marked by arrow heads in Fig. 32View FIGURES 25 – 33. Abd. 4 with 4 + 4 (3–5, 1 individual with 7) posterior setae. Anterior face of collophore with 3 (4) distal macrosetae and 4 (3–6) microsetae, lateral setae 8–20, but region partially obscured in most individuals and actual number of setae difficult to ascertain (individual with 8 setae is 1.2 mm long, the smallest individual for which number of setae could be determined with confidence), posterior face of collophore ( Fig. 33View FIGURES 25 – 33) with 2 + 2 (1 + 1–4 + 4) short ciliate setae in row parallel to distal margin (joined by dotted lines in Fig. 33View FIGURES 25 – 33) and 1 + 1 (or 2 + 2) perpendicular to the distal margin. Proportion of dens/manubrium≈ 1.2; proportion of dental vesicle/mucro≈ 1. Mucro bidentate, most individuals with both teeth worn (1 individual 14 M= macrosetae. (2) Prelabral setae are ciliate in all species studied. (3) Setae along ventral groove. (4) Chaetotaxy from Yoshi 1981. (5) Parentheses show variation observed when more than 2 individuals were examined. (6) All individuals with 3 setae on one side of the body had 4 or more setae on the other side. (7) ARG= Argentina; BRA = Brazil; COL = Colombia; CR= Costa Rica; CUB= Cuba; GUAD = Guadeloupe; MEX = Mexico; PAN= Panama; PR= Puerto Rico; USA = United States. (8) Species groups: W= beta  , celebensis  ; B= borneensis.

Remarks: Salina thibaudi  n. sp. differs from all other species with bidentate mucro by the combined presence of 4 dorsal macrosetae on Ant. 1, 4 prelabral setae, 7 macrosetae on Th. 2, 6 on Th. 3, and at least 4 posterior setae on Abd. 4. Additional differences with other species are listed in Table 1.
