Total length (head + trunk) of holotype 1.73 mm. Specimens pale yellow with irregular light blue color on antenna, head, Th II–Abd V. Legs pale yellow. Eyepatches black ( Figure 9FView Fig).

Head. Ant I dorsally with 3 mac and 5 basal spiny smooth mic ( Figure 10FView Fig). Posterior labial chaetotaxy series ‘CG’ with 4–5 ciliate chaetae ( CG 1-3, CG 5, CG 7), CG 2 present or absent, and 2 serrated mic ( CG 4, CG 6); series ‘PLM’ with 2 ciliate chaetae ( PLM 1–2); series ‘PLE’ with 2 ciliate chaetae ( PLE 1–2); lateral side with about 13 ciliate chaetae ( Figure 11FView Fig).

Dorsal chaetotaxy. Th II with 1 ‘m’ mac (m7); 1 ‘p’ mac (p3); Th III with 1 ‘p’ mac (p3) ( Figure 12FView Fig). Abd I with 1 ‘m’ mac (m4) ( Figure 13FView Fig). Abd III with 2 ‘m’ mac (am6, pm6); 1 ‘p’ mac (p6) and 1 ‘p’ mes (p7i) ( Figure 14BView Fig). Abd IV with 2 ‘A’ mac (A1, A6); 3 ‘B’ mac (B3–5); 1 ‘Be’ mac (Be1); 1 ‘C’ mac (C1); 3 ‘E’ mac (E1–2, E4); 4 ‘F’ mac (F1–F3p); 2 ‘Fe’ mac (Fe1, Fe6); posterior side with 4 sens type IV (ps and three unnamed) ( Figure 14IView Fig). Abd V with 2 ‘a’ mac (a3, a5); 3 ‘m’ mac (m2–3, m5); and 5 ‘p’ mac (p0-4) (similar to S. brasiliana  sp.n.) ( Figure 15AView Fig).

Appendages. Trochanteral organ with 14 smooth spine-like chaetae ( Figure 16FView Fig). 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 18CView Fig). Manubrial plate with 3 chaetae ( Figure 19CView Fig). Mucro with 3–4 teeth (d1, ap, v1) ( Figure 19HView Fig).


This species name refers to the locality where the species was found in Peru.


Salina peruana  sp.n. resembles S. unisetosa  sp.n. 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, S. peruana  sp.n. differs of this species by dorsal chaetotaxy of Abd III with 3 lateral mac (6 in S. unisetosa  sp.n.), and Abd IV without Ae1, E3 and Fe3 mac (present in S. unisetosa  sp.n.). Other characteristic that is different in S. peruana  sp.n. is cephalic groove with 6–7 chaetae (8 in S. unisetosa  sp.n), collophore with 7 anterior chaetae (3 mac equal), 1 posterior chaetae and 12 chaetae on lateral flap, while S. unisetosa  sp.n. has 8 anterior chaetae (3 mac unequal), 2 posterior chaetae and 15 chaetae lateral flap. The color reduction in S. peruana  sp.n. also differs, since S. unisetosa  sp.n. has appendages yellowish. For additional information, refer to Table 2.
