Specimens pale yellow with irregular light blue color on antenna, head, Th II–Abd V. Legs pale yellow. Eyepatches black (Figure 9F). Head. Ant I dorsally with 3 mac and 5 basal spiny smooth mic (Figure 10F). Posterior labial chaetotaxy series ‘CG’ with 4–5 ciliate chaetae (<b>CG 1-3</b>, <b>CG 5</b>, <b>CG 7</b>), <b>CG 2</b> present or absent, and 2 serrated mic (<b>CG 4</b>, <b>CG 6</b>); series ‘PLM’ with 2 ciliate chaetae (<b>PLM 1–2</b>); series ‘PLE’ with 2 ciliate chaetae (<b>PLE 1–2</b>); lateral side with about 13 ciliate chaetae (Figure 11F). Dorsal chaetotaxy. Th II with 1 ‘m’ mac (<b>m7</b>); 1 ‘p’ mac (<b>p3</b>); Th III with 1 ‘p’ mac (<b>p3</b>) (Figure 12F). Abd I with 1 ‘m’ mac (<b>m4</b>) (Figure 13F). Abd III with 2 ‘m’ mac (<b>am6</b>, <b>pm6</b>); 1 ‘p’ mac (<b>p6</b>) and 1 ‘p’ mes (p7i) (Figure 14B). Abd IV with 2 ‘A’ mac (<b>A1</b>, <b>A6</b>); 3 ‘B’ mac (<b>B3–5</b>); 1 ‘Be’ mac (<b>Be1</b>); 1 ‘C’ mac (<b>C1)</b>; 3 ‘E’ mac (<b>E1–2</b>, <b>E4</b>); 4 ‘F’ mac (<b>F1–F3p</b>); 2 ‘Fe’ mac (<b>Fe1</b>, <b>Fe6</b>); posterior side with 4 sens type IV (<b>ps</b> and three unnamed) (Figure 14I). Abd V with 2 ‘a’ mac (<b>a3</b>, <b>a5</b>); 3 ‘m’ mac (<b>m2–3</b>, <b>m5</b>); and 5 ‘p’ mac (<b>p0-4</b>) (similar to <i>S. brasiliana</i> <b>sp.n.</b>) (Figure 15A). Appendages. Trochanteral organ with 14 smooth spine-like chaetae (Figure 16F). Collophore anterior side with 3 subapical mac of equal length, and 4 proximal smooth mic; posterior side with 1 apical smooth chaetae; lateral flap formula 5(s), 2(m), 5(i) smooth chaetae, 1 inferior larger (Figure 18C). Manubrial plate with 3 chaetae (Figure 19C). Mucro with 3–4 teeth (<b>d1</b>, <b>ap</b>, <b>v1</b>) (Figure 19H). <i>Etymology</i> This species name refers to the locality where the species was found in Peru. <i>Remarks</i> <i>Salina peruana</i> <b>sp.n.</b> resembles <i>S. unisetosa</i> <b>sp.n.</b> in reduced body color, Ant I with 3 mac, manubrial plate with 3 chaetae and Th II–Abd I with 1, 1, 1 central mac, respectively. However, <i>S. peruana</i> <b>sp.n.</b> differs of this species by dorsal chaetotaxy of Abd III with 3 lateral mac (6 in <i>S. unisetosa</i> <b>sp.n.</b>), and Abd IV without <b>Ae1</b>, <b>E3</b> and <b>Fe3</b> mac (present in <i>S. unisetosa</i> <b>sp.n.</b>). Other characteristic that is different in <i>S. peruana</i> <b>sp.n.</b> is cephalic groove with 6–7 chaetae (8 in <i>S. unisetosa</i> <b>sp.n</b>), collophore with 7 anterior chaetae (3 mac equal), 1 posterior chaetae and 12 chaetae on lateral flap, while <i>S. unisetosa</i> <b>sp.n.</b> has 8 anterior chaetae (3 mac unequal), 2 posterior chaetae and 15 chaetae lateral flap. The color reduction in <i>S. peruana</i> <b>sp.n.</b> also differs, since <i>S. unisetosa</i> <b>sp.n.</b> has appendages yellowish. For additional information, refer to Table 2.
